Response of Bacterial Community and Enzyme Activity of Greenhouse Tomato under Different Irrigation Systems

The micro-sprinkler irrigation mulched(MSM)has been suggested as a novel water-saving approach in con-trolled environment agriculture.However,the effects of microbial community structure and enzyme activity in the rhizosphere soil on crop growth under MSM remain unclear.This study conducted a randomized experimen-tal design using greenhouse tomatoes to investigate changes in bacterial community structure and enzyme activity in rhizosphere soil under different irrigation frequencies(F)and amounts(I)of MSM.Thefindings revealed that with the increase of F or I,The total count of soil bacteria in tomatoesfirst rose and then fell in terms of Opera-tional Taxonomic Units(OTUs)classification.Compared to other F,the most abundance of nitrogen and phos-phorus metabolism genes and enzyme activities were observed with a 5-day F.Moreover,the diversity of soil bacterial community structure initially rose before eventually declining with the increase of the I.Applying 1.00 Epan(cumulative evaporation of a 20 cm standard pan)under MSM helped boost the abundance of nitrogen and phosphorus metabolism functional genes in soil bacteria,ensuring higher enzyme activities related to nitro-gen,carbon,and phosphorus metabolism in the rhizosphere soil of tomatoes.Tomatoes’yield initially rose before eventually declining with the increase in F or I,whereas I had a more significant effect on yield.A 1.00%increase in I yielded a minimum of 39.24%increase in tomato yield.The study showed a positive correlation between soil bacterial community,soil enzyme activity,and greenhouse tomato yield under MSM.Considering the results comprehensively,the combined irrigation mode of F of 5 d and I of 1.00 Epan was recommended for greenhouse tomatoes under MSM.This conclusion provides theoretical support for water-saving practices and yield improve-ment in facility agriculture,especially tomato cultivation.

Study on Growth and Development and Dry Matter Production of Greenhouse Tomato in North China

[Objective] This study aimed to investigate the growth and development and dry matter production and allocation of greenhouse tomato in North China. [Method] With tomato cultivar ＇Jinguo No.l＇ as the experimental material, the ex- periments were conducted in a solar greenhouse located in Taigu, Shanxi （37o25＇ N, 112o25＇ E） from March to July, in 2014 and 2015. [Result] The plant height, leaf number, leaf area and dry matter production of greenhouse tomato increased lin- early with the increased days after transplantation, and their growth rates were 2.74 cm/d, 0.32 leaf/d, 70 cm2/d and 9.4 g/（m2.d）, respectively. The fruit dry weight also showed a linear relationship with the plant dry weight. After fruit setting, the fruit dry weight was increased by about 0.69 g when the plant dry weight was increased by 1 g. The allocation proportions of dry matter in tomato roots, stems and leaves de- clined significantly from plant flowering to fruiting, while the proportion of fruit dry weight in plant dry weight increased significantly, exceeding 60%. There was a strong linear relationship between dry matter production of tomato and effective cu- mulative temperature （sum of temperature higher than 10 ^（3） in the solar green- house, and the dry matter production was increased by about 0.73 g/m2 when the effective cumulative temperature was increased by one unit. The dry matter produc- tion of tomato plant also showed a strong linear relationship with photosynthetic ac- tive radiation （PAR） in the greenhouse, and about 3.4 g of dry matter was synthe- sized per unit （M J） of PAR. [Conclusion] Extending the growing period and improv- ing the temperature and light conditions could increase the dry matter production of tomato.

Translocation and recovery of 15N-labeled N derived from the foliar uptake of 15NH3 by the greenhouse tomato（Lycopersicon esculentum Mill.）

In order to completely evaluate ammonia emission from greenhouse vegetable fields,crop canopy absorption should not be neglected.The foliar uptake of NH3 applied at two growth stages and the subsequent 15N-labeled N translocation to other plant components were investigated under greenhouse conditions using chambers covered with the soil of a tomato field.Treatments comprised three NH3-N application rates(70,140,and 210 mg/plot) using 15N-labeled ammonium sulfate.Plants were harvested immediately after exposure for 24 h,and the total N concentrations and 15N/14 N ratios were determined.With increased NH3 concentration,total 15NH3-N absorption increased considerably,whereas the applied 15NH3-N uptake decreased gradually.The tomato plants absorbed 33-38% and 24-31% of the 15NH3-N generated at the anthesis and fruit growth stages,respectively.A total of 71-80% of the recovered NH3 was observed in the leaves and 20-30% of the recovered NH3 was remobilized to other components.Among them,an average of 10% of the absorbed 15NH3-N was transferred into the tomato fruits.All these results indicated the potential of the tested tomatoes for the foliar uptake of atmospheric 15NH3 and the distribution of 15N-labeled vegetative N among different plant components.The results are of great importance for the complete evaluation of nitrogen use efficiency in the greenhouse tomato fields.

Effect of Bacillus subtilis and Pseudomonas fluorescens on Growth of Greenhouse Tomato and Rhizosphere Microbial Community

Bacillus subtilis （B. subtilis） and Pseudomonas fluorescens （P. fluorescens） are two of the most important plant growth promoting rhizobacteria （PGPR） in agriculture. An in situ trial was conducted on greenhouse tomato （Lycopersicum esculentum Mill.） to examine the effect of two bacterial strains, Bacillus subtilis （CGMCC 1.3343） and Pseudomonas fluorescens （CGMCC 1.1802）, on tomato growth, gray mold disease control, catabolic and genetic microbial features of indigenous rhizosphere bacteria under lownitrogen conditions. A commercial inoculant （ETS） was also tested as a comparison. Both B. subtilis and P. fluorescens promoted growth and biomass of seedlings, while only B. subtilis was efficient in reducing gray mold incidence in greenhouse tomato. The two bacterial strains could colonization in tomato rhizosphere soil at the end of experiment （10 days after the last inoculation）. Different AWCD trends and DGGE patterns were got in different bacterial treatments; however, analyses of microbial diversities showed that indigenous soil microbes did not seem to have significant differences at either the catabolic or genetic level among treatments. ETS, as a commercial microbial agent, promoted plant growth and gave a higher microbial diversity in rhizosphere soil.

The effects of aeration and irrigation regimes on soil CO_2 and N_2O emissions in a greenhouse tomato production system

Aerated irrigation has been proven to increase crop production and quality, but studies on its environmental impacts are sparse. The effects of aeration and irrigation regimes on soil CO2 and N2O emissions in two consecutive greenhouse tomato rotation cycles in Northwest China were studied via the static closed chamber and gas chromatography technique. Four treatments, aerated deficit irrigation（AI1）, non-aerated deficit irrigation（CK1）, aerated full irrigation（AI2） and non-aerated full irrigation（CK2）, were performed. The results showed that the tomato yield under aeration of each irrigation regime increased by 18.8% on average compared to non-aeration, and the difference was significant under full irrigation（P〈0.05）. Full irrigation significantly increased the tomato yield by 23.9% on average in comparison to deficit irrigation. Moreover, aeration increased the cumulative CO2 emissions compared to non-aeration, and treatment effects were significant in the autumn-winter season（P〈0.05）. A slight increase of CO2 emissions in the two seasons was observed under full irrigation（P〉0.05）. There was no significant difference between aeration and non-aeration in soil N2O emissions in the spring-summer season, whereas aeration enhanced N2O emissions significantly in the autumn-winter season. Furthermore, full irrigation over the two seasons greatly increased soil N2O emissions compared to the deficit irrigation treatment（P〈0.05）. Correlation analysis indicated that soil temperature was the primary factor influencing CO2 fluxes. Soil temperature, soil moisture and NO3^- were the primary factors influencing N2O fluxes. Irrigation coupled with particular soil aeration practices may allow for a balance between crop production yield and greenhouse gas mitigation in greenhouse vegetable fields.

Tomato and cowpea crop evapotranspiration in an unheated greenhouse

With the development of protected cultivation of vegetables in China, it is necessary to study the water requirements of crops in greenhouses. Lysimeter experiments were carried out to investigate tomato （2001） and cowpea （2004） crop evapotranspiration （ETc） in an unheated greenhouse in Eastern China. Results showed remarkably reduced crop evapotranspiration inside the greenhouse as compared with that outside. ETc increased with the growth of the crops, and varied in accordance with the temperature inside the greenhouse and 20-cm pan evaporation outside, reaching its maximum value at the stage when plants’ growth was most active. Differences between the variation of crop evapotranspiration and pan evaporation inside the greenhouse were caused by shading of the pan in the later period when the crops were taller than the location where the pan was installed, 70 cm above ground. The ratio of crop evapotranspiration to pan evaporation was not constant as reported in previous studies, and the variation of the inside ratio αin lagged behind that of the outside ratio αout. Simulation of crop evapotranspiration based on 20-cm pan evaporation inside the greenhouse is more reasonable than that based on 20-cm pan evaporation outside, although pan evaporation outside is more consistent with ETc than that inside. The value of αin, calculated based on air temperature, relative humidity, and ground temperature inside, plays a dominant role in the calculation of ETc. As the crop height increases, altering the location of the inside pan and placing it above the canopy, out of the shade, would help to achieve more reasonable values of crop evapotranspiration.

Therefore, to solve the various problems that exist at present, some efforts are needed achieve a better production model.

Emission Characteristics of Soil Nitrous Oxide from Typical Greenhouse Vegetable Fields in North China

To make clear the emission characteristics of soil N20 from typical green- house vegetable fields in North China, an experiment was conducted in greenhouse tomato field in Shouguang city, Shandong province, China＇s ＂Home of Vegetables＂. The N2O fluxes were observed in four experimental treatments, as follows： none N fertilizer （CK）, single organic fertilizer （OM）, conventional fertilization （FP） and opti- mized and reduced nitrogen fertilization （OPT）, by a close chamber-gas chromato- graph method. The effects of different fertilization treatments on N2O emission and tomato yield were analyzed. The results showed that following the fertilization and ir- rigation, the pulsed emissions of N2O were measured. The N2O emission peak ap- peared after basal fertilizer application and irrigation and could be maintained for about 20 days. While the N2O emission peak caused by topdressing was smaller and last only 3-5 days. The statistical analysis showed that the N2O fluxes were affected by air temperature, soil temperature and WFPS at soil depth of 3 cm. The total contents of soil N2O fluxes had significant differences among experimental groups. The total content orderly was FP of 14. 77 kg/hm^2, OPT of 9. 73 kg/hm^2, OM of 6.84 kg/hm^2 and CK of 2.37 kg/hm^2. The N~：~ emission coefficient ranged from 0.83%-1.10%,which was close to or more than the recommended value （1.0%） by IPCC. Compared with the FP treatment, the tomato yield in OPT treatment, whose application rate of chemical N fertilizer decreased by about 60%, increased by 2.2%. Under the current management measures, the reasonable reduction on ap- plicaUon rate of organic manure and chemical nitrogen fertilizer could effectively re- duce the N=O emissions in greenhouse vegetable fields.

基于RGB和深度双模态的温室番茄图像语义分割模型

图像语义分割作为计算机视觉领域的重要技术,已经被广泛用于设施环境下的植物表型检测、机器人采摘、设施场景解析等领域。由于温室环境下未成熟番茄果实与其茎叶之间具有相似颜色,会导致图像分割精度不高等问题。该研究提出一种基于混合Transformer编码器的“RGB+深度”(RGBD)双模态语义分割模型DFST(depth-fusion semantic transformer),试验在真实温室光照情况下获得深度图像,对深度图像做HHA编码并结合彩色图像输入模型进行训练,经过HHA编码的深度图像可以作为一种辅助模态与RGB图像进行融合并进行特征提取,利用轻量化的多层感知机解码器对特征图进行解码,最终实现图像分割。试验结果表明,DFST模型在测试集的平均交并比可达96.99%,对比不引入深度图像的模型,其平均交并比提高了1.37个百分点;DFST模型对比使用卷积神经网络作为特征提取主干网络的RGBD语义分割模型Shape Conv,其平均交并比提高了2.43个百分点。结果证明,深度信息有助于提高彩色图像的语义分割精度,可以明显提高复杂场景语义分割的准确性和鲁棒性,同时也证明了Transformer结构作为特征提取网络在图像语义分割中也表现出了良好的性能,可为温室环境下的番茄图像语义分割任务提供解决方案和技术支持。

不同土壤改良措施对胶东酸化设施菜田的改良效果

设施菜田表层土壤酸化是限制蔬菜产量、品质提升的重要因素,土壤改良剂以及有机肥的施用是缓解土壤酸化的重要措施。通过在山东海阳开展田间试验,设计对照处理、硅钙钾镁土壤调理剂处理、贝壳粉调理剂处理筛选酸性土壤改良剂,在此基础上设计对照处理以及鸡粪源、牛粪源、粉丝废物源3种不同来源有机肥处理,旨在揭示不同土壤改良剂和不同来源有机肥对设施番茄产量品质的影响,为进一步优化施肥、改良土壤、提升番茄产量品质提供理论依据。结果表明:胶东设施菜田表层土壤有酸化趋势,pH降低0.06个单位,与传统对照处理相比,施用硅钙钾镁土壤调理剂可以平均提高两茬番茄产量12.9%,与番茄果径和单果质量的升高有关,施用硅钙钾镁土壤调理剂和贝壳粉调理剂处理的两茬番茄果实VC含量平均提高15.0%和12.2%。在施用硅钙钾镁土壤调理剂的基础上,鸡粪源有机肥和粉丝废物源有机肥可以平均显著提高两茬番茄产量,增幅分别为15.4%和17.8%,与番茄株高、番茄果径及单果质量的增加有关,粉丝废物源有机肥可以显著提高两茬番茄VC含量14.9%。相关分析表明,0~20 cm土层土壤pH与产量以及植株株高、果实果径、单果质量、果实VC含量显著正相关。综上,硅钙钾镁土壤调理剂配合粉丝废物源有机肥可以缓解设施番茄表层土壤酸化,达到增产提质的目的。

基于产量和N_(2)O排放的温室番茄灌溉模式

为了揭示设施菜地N_(2)O排放的变化规律,了解水肥气耦合对设施菜地土壤N_(2)O的影响,对不同水肥气处理进行综合评价,提出合理的减排措施。试验以番茄为供试作物,设置了灌水水平(I)、施肥水平(F)和加气水平(A)3个因素,以不加气(CK)充分灌溉条件下2个施肥水平为对照,设置I1和I2(分别为亏缺灌溉和充分灌溉,对应作物-皿系数(K_(cp))分别为0.8和1.0)2个灌水水平,F1和F2(分别为低肥和高肥,对应施氮量为180 kg·hm^(-2)和240 kg·hm^(-2))2个施肥水平,A1和A2(分别为1倍气和2倍气)2个加气水平,共10个处理。采用静态暗箱-气相色谱法对番茄全生育期N_(2)O排放进行监测分析,系统研究水肥气耦合对温室番茄土壤N_(2)O排放的影响及其影响因素。结果表明:灌水量和施肥量的增加均会增加土壤N_(2)O排放通量,I2处理的N_(2)O排放通量比I1处理平均增加14.79%(P>0.05),F2处理比F1处理平均增加34.90%(P<0.05)。加气灌溉对土壤N_(2)O排放通量有显著影响,与CK处理相比,A1和A2处理分别增加10.02%(P>0.05)和62.92%(P<0.05)。土壤N_(2)O排放通量与土壤充水孔隙度呈指数正相关关系,与NO_(3)^(-)-N含量呈指数正相关关系,当土壤温度小于等于26℃时,N_(2)O排放通量与土壤湿度呈指数正相关关系,土壤温度大于26℃时,呈线性负相关关系。综合考虑番茄产量、N_(2)O累积排放量、灌溉水分利用效率、氮肥偏生产力和单产N_(2)O累积排放量,推荐施肥量为180 kg·hm^(-2)的1倍气充分灌溉(K_(cp)=1.0)为温室番茄增产、节水、减排的较佳灌溉模式。

不同灌水处理下CROPGRO-Tomato模型全局敏感性和不确定性分析

作物品种参数和土壤参数是作物生长过程模拟和产量预测过程中的基本输入参数,输出变量对输入参数的敏感性分析对提高作物模型的模拟精度具有重要作用。依据辽宁地区的温室番茄田间试验资料,进行了不同灌水水平下CROPGRO-Tomato模型的全局敏感性分析。在4个灌水处理(50%θf、60%θf、70%θf和80%θf为灌水下限,θf为田间持水率)条件下,利用SimLab软件,采用Morris法和EFAST法分析了CROPGRO-Tomato模型的5个输出变量(番茄的开花期、成熟期、产量、地上干物质量和最大叶面积指数)对作物品种参数和土壤参数的全局敏感性,并对两种方法的分析结果进行了比较,同时对EFAST法分析结果进行了不确定性分析。结果表明:两种方法分析得到的开花期天数、成熟期天数、地上干物质量和最大叶面积指数的分析结果相关性较高;产量方面,两种方法得到的XFRT(每日分配给果实的干物质量的最大比例)、EMFL(出苗到第一朵花出现的光热时间)、LFMAX(最适条件下叶片最大光和速率)等作物品种参数的敏感度排序基本一致。其中最敏感参数为XFRT,在EFAST法和Morris法中其值分别为0.505和1305;两种方法得到开花期、成熟期、地上干物质量和叶面积指数等输出变量的最敏感参数均为EMFL。其中EFAST法得到的上述各参数依次为0.999,0.615,0.463,0.690;Morris法得到的各参数依次为19.9,18.2,2450,5.13;不确定性分析结果表明:当土壤水分在70%θf和80%θf条件下,CROPGRO-Tomato模型对番茄生育期划分和地上干物质量的模拟精度比在50%θf和60%θf水分条件下平均高7.25%。研究结果为利用DSSAT-CROPGRO-Tomato模型模拟辽宁地区温室番茄生长过程中参数的优化和适用性的提高提供理论依据。
