Adjusted Nutrition Solution Formula Improves the Growth and Yield of Soilless Tomato Culture in Southern Xinjiang

The tomato production facilities in southern Xinjiang have unique climatic conditions.However,due to the high salinity and degree of mineralization of the soil and the extensive management of irrigation water sources,the tomato production efficiency is low,and there is still much room for improvement.In this study,the formulas of tomato nutrient solutions were adjusted according to the local irrigation water quality characteristics,and tomato was grown in a greenhouse using sand cultivation.To select a nutrient solution formula suitable for the tomato cultivated in the local facilities,various parameters of tomato treated with different formulas were compared.The results showed the following:①Adjusting the nutrient solution formula could effectively improve the vegetative and reproductive growth indexes of tomato.②Properly decreasing the nutrient solution concentration could improve the growth indexes of tomato.③Decreases in Ca^(2+) and Mg^(2+) in the nutrient solution did not affect the growth and yield of tomato.The possible reason for the third result was that excessive cations in the water inhibited the absorption of Ca^(2+) and Mg^(2+) in the nutrient solution and had antagonistic effects.Therefore,a high nutrient solution concentration does not necessarily promote the growth of tomatoes.In summary,this study will improve the production conditions of protected tomato in the southern Xinjiang area by supporting tomato nutrient solution adjustments according to actual conditions in combination with reasonable irrigation systems and scientific management.

Exploration on Ideological and Political Construction of Higher Vocational English Course in Southern Xinjiang from the Perspective of "Cultural Confidence"

At present,the lack of Chinese culture in higher vocational English teaching in southern Xinjiang is serious.The existing English curriculum system is not enough to support the goal of cultivating ethnic minority college students cultural confidence,and its curriculum ideological and political construction is still in the initial stage of exploration.The combination of the Chinese national culture and the ethnic culture of Xinjiang and the ideological and political elements organically integrated into cultural confidence have endowed the vocational English education in Xinjiang with the characteristics of the times.In this paper,from the perspective of China s"cultural confidence",ideological and political elements were explored,and the background of ideological and political construction in higher vocational English teaching course in southern Xinjiang was analyzed;it is expounded that the ideological and political construction is an inevitable requirement for the high-quality development of vocational English education in southern Xinjiang,and the content design and implementation path of higher vocational English course was explored to provide new ideas and new ways for the curriculum ideological and political construction of higher vocational English teaching in southern Xinjiang.

Historical climate changes in southern Xinjiang

Based on the synthetic researches of multi-index geologic records of Niya section, which are of high resolution in southern margin of the Tarim Basin, together with other geologic records in southern Xinjiang, this paper has reconstructed the history of paleoclimatic changes in this region since about 4.00 ka BP. During the last 4.00 ka, the region of southern Xinjiang has experienced alternations of relative cold-wet and relative warm-dry periods. Three remarkable cold-wet periods (4.00-3.45 ka BP., 2.50-1.90 ka BP., ca.1.40-1.00 ka BP.) and three warm-dry periods (3.45-2.50 ka BP., 1.90-1.40 ka BP., 1.00 ka BP.-present) are identified. It is shown that human activities have an intimate relation with the evolution of paleoclimate in southern Xinjiang.

Research on the Seismotectonic Zones and Seismicity State in the Southern Xinjiang Region

Based on the studies of earthquake activity, tectonic movement, crustal shortening rate, fault activity, local stress field and historical characteristics of strong earthquake activities in Xinjiang, we divide the south part of Xinjiang into 4 seismotectonic zones, namely, the eastern segment of south Tianshan seismic belt, the Kalpin block, the Kashi-Wuqia junction zone, and the west Kunlun Mountains seismic belt. Using earthquake catalogues from Xinjiang since 1900, and on the basis of integrity analysis of earthquake records in different magnitude ranges, the seismicity state of different seismotectonic zones is analyzed quantificationaUy by calculating the mean value of annual strain energy release, annual rate of earthquakes with different lower limits of magnitude, b-value, and the parameter m of accelerating strain release model. The characteristic indexes of seismicity state for each of the seismic tectonic zones are then determined, which provide a quantitative basis for earthquake tendency analysis and judgment.

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

Surface pollen and modern vegetation in Southern Xinjiang,China

The study of modern pollen,and vegetation can improve the accuracy of paleoenvironmental reconstruction based on fossil pollen data.A total of 188 pollen surface samples were collected from Southern Xinjiang(34°00’–43°00’N,74°00’–94°00’E)in China,with an elevation range of 888–4530 m.Surface pollen and vegetation were studied in the northern region of the Kunlun Mountains and the southern region of the Tianshan Mountains.The results showed that the surface pollen assemblages on the southern slope of the Tianshan Mountains(3530–1124 m)were divided into three pollen zones,namely,montane steppe,montane desert steppe,and montane desert.These zones were dominated by Artemisia,Chenopodiaceae,and Ephedra pollen.The surface pollen assemblages in the eastern Pamir Plateau(4530–1287 m)could be divided into alpine meadow,montane desert steppe,and montane desert zones,which were predominantly characterized by Artemisia,Chenopodiaceae,and Asteraceae pollen.However,the Southern Tarim Basin(3548–888 m)comprised montane desert steppe and montane desert zones,which was dominated by Artemisia and Chenopodiaceae pollen.The geographic distribution of the surface pollen sites obtained using ArcGIS,the R-value,and Pearson correlation analyses indicated that the over-represented Picea and Pinus pollen were of external origin and were transported by wind,water(rivers),and ice(glacier movement).Over-representation of Ephedra and Nitraria pollen was mainly distributed in the montane desert and desert steppe zones,respectively.Pollen from Chenopodiaceae and Artemisia were over-represented and broadly distributed across Southern Xinjiang.Juglans pollen was concentrated in areas with walnut trees,strongly indicating the presence of local parent plants.According to the Hybrid Singleparticle Lagrangian Integrated Trajectory model,more Pinus pollen was transported to the Pamir region by external airflows during spring and summer,resulting in its higher surface pollen content.Research elucidating the relationship between modern pollen and vegetation in southern Xinjiang could provide data describing the surface palynological database of Xinjiang for use in large-scale paleoenvironmental reconstructions.

Moisture transport and sources of an extreme rainfall event of June 2021 in southern Xinjiang, China

A highly extreme rainfall event occurred during June 15-17,2021(21·6 event)over southern Xinjiang(SXJ)of China,with daily rainfall overwhelming the climatological annual total at three national stations along the north of Kunlun Mountains.During this event,the SXJ is situated upstream of the 500 hPa trough line and close to the 200 hPa upper jet stream entrance,favouring the upper(lower)level divergence(convergence)with intensified ascending motions and prominent moisture convergence.We examined the moisture paths and sources for this significant rainfall event using the Hybrid Single-Particle Lagrangian Integrated Trajectory(HYSPLT)model.The findings indicate that the majority of the moisture sources are located in areas west of the SXJ,extending from central Asia to the North Atlantic,whereas only a small number of trajectories originate from areas south or east of the SXJ.Seven relevant moisture sources for the rainfall event have been divided.About 80.0%of the total moisture is contributed by central Asia,which ranks top in terms of moisture contribution(∼33.2%),north Eurasia(∼25.7%),and water areas(∼17.7%),including the Mediterranean,Black and Caspian Sea region,while fractional moisture contributions among the other four regions are all below 8.0%.When compared to other parts of China(such as South China and East China),where southerly and/or easterly trajectories are the predominant moisture channels,the distribution patterns of moisture trajectories during this event are noticeably different.

How did high temperature extremes in southern Xinjiang,China induce the repaid rise in jujube futures prices in the summer of 2021?

In the summer of 2021,southern Xinjiang,China,experienced a temporary period of high temperature extremes.Because of this weather event,jujube futures prices rose by more than 50%in a short time.To clarify the influence mechanism of these two events,we investigated the current status of jujube farming and collected investors’online comments.We analysed these comments specifically using textual analysis tools,such as co-word networks.Results showed that the concerns of investors about the reduction in jujube production triggered by high temperature extremes were the primary reason for the rapid rise in jujube futures prices.Especially in combination with the cultivation density of jujube and their adaptability to the growing environment,a new understanding can be obtained.That is to say,when a crop is excessively densely cultivated in a region and is highly sensitive to a meteorological variable anomaly at a certain growth stage,a less destructive local extreme weather event could induce severe panic among investors regarding production reduction and thus influence the normal changes in futures price.In response to the impact mechanisms revealed in this study,we proposed policy recommendations,such as strengthening the degree of crop damage disclosure and designing weather futures derivatives,to address similar situations in the future.This study not only fills the gap in the research on the impact paths of high temperature extremes on jujube futures prices but also has a reference value for securing the stability of futures prices of related agricultural products in the future.

地膜覆盖和灌溉量对棉田土壤水盐分布特征的影响

为探究不同地膜覆盖和灌溉量对南疆棉田土壤水盐分布特征的影响,本研究于2021—2022年在新疆阿克苏地区沙雅县棉花地开展试验,以裸地(M0)为对照,设置高堡膜覆盖(M1)和普通PE地膜覆盖(M2)2种地膜处理,以及3150(W1)、4050(W2)、4950 m3·hm^(-2)(W3)3个灌溉量,分析了不同地膜覆盖和灌溉量对棉田0~60 cm土壤含水率、盐分、水盐分布均匀系数、盐分变化量和脱盐率的影响。结果表明:2021—2022年,随着灌溉量的增加,棉田土壤的含水量均呈上升趋势,盐分显著降低。棉田土壤水分的纵向运移能力均显著提高,膜间上层土壤盐分的淋溶效果显著,但水分分布均匀度和盐分分布均匀度均逐渐下降,盐分变化量和脱盐率随着灌溉量的增加而增大。M1处理0~60 cm土层平均土壤含水率较M0和M2处理分别高5.76%~14.03%和0.86%~2.22%,且M1处理可显著提高土壤水分分布的均匀度。随着时间的推进,各处理上层(0~30 cm)的土壤含盐量呈先降低后升高的变化趋势,下层(30~60 cm)的土壤含盐量逐渐升高;M0处理0~60 cm土层平均含盐量较M1和M2处理分别高24.22%~35.87%和18.88%~30.64%,M1和M2处理的盐分分布均匀度下降。在二者互作条件下,W3M1处理的土壤含水率最高,2021、2022年分别为26.48%、23.99%,水分的纵向运移能力显著提高,上层土壤盐分降低,W3M2(2021)、W3M1(2022)的盐分变化量和脱盐率最高,分别为0.33 g·kg^(-1)和38.66%、0.33 g·kg^(-1)和45.65%。综上所述,在高堡膜覆盖条件下,采用4950 m3·hm^(-2)的灌溉量时,可提高棉田土壤含水率,显著降低膜间土壤含盐量,有利于土壤排盐,降低土壤次生盐渍化,促进棉花根系的生长。

Zircon U-Pb Dating of Yushugou Terrain of High-Pressure Granulite Facies in Southern Tianshan Mountain and Its Geological Significance

The Yushugou terrain of high\|pressure granulite facies in southern Tianshan Mountain is composed mainly of an ophiolite suite. Most selected zircons are round or elliptical in shape, and some are of tetragonal prism with round edges. The granulometric analyses show that they are well sorted in sedimentation. ZrO\-2/HfO\-2 ratios in zircons range from 45 to 57. These characters, together with the petrologic and geochemical characters of plagioclase\|garnet\|orthopyroxenite bearing zircons, indicate that the protolith of plagioclase\|garnet\|orthopyroxenite may be derived mainly from volcanic base surge sedimentary debris in oceanic islands and from clays formed by seafloor weathering. Zircons are simply of pyroclastic debris. The ophiolite formation age of (440±18) Ma and the first\|stage metamorphic age (amphibolite or granulite facies) of (364±5) Ma were obtained with a method of multiple grains in different groups and a method of concordia plot. These ages provide important information on the temporal and spatial occurrence of southern Paleozoic Tianshan Ocean, the subduction rate of the oceanic crust and the formation mechanism of ophiolite of granulite facies.

不同肥密措施对南疆水稻抗倒伏及干物质生产特性和产量的影响

以新稻36号为材料,在南疆地区进行了以氮肥水平(N)作为主区、栽插密度(D)作为副区的田间裂区试验。结果表明,随施氮量增加,第1节间长度、第2节间长度、弯曲力矩、株高和重心高度显著增加,抗折力则先增后降以N2处理(纯N 240 kg/hm^(2))最高;合理密植能够控制个体发育,降低节间长度、弯曲力矩、株高与重心高度;茎秆倒伏指数由上述因素共同影响,施氮量240 kg/hm^(2)、栽插密度20.83~27.78万丛/hm^(2)的处理抗倒伏性较优。花后干物质积累量对籽粒贡献占比为51.69%~76.14%,是籽粒干物质积累量的主要来源,适当增施氮肥能够提高花后干物质积累量与积累率;过量施肥则会使干物质在花前的积累量增大,多用于营养器官生长,不利于向籽粒转运。适度密植有利于提高花后干物质积累量,D4处理(27.78万丛/hm^(2))较其他处理提高18.06%~30.22%,同时也促进了干物质向籽粒的转运。综合来看,施氮量240 kg/hm^(2)、栽插密度27.78万丛/hm^(2)时能显著改善水稻地上部分干物质的比例及干物质分配,且未发生倒伏,有利于产量提高。

南疆典型灌区春播前表层土壤含水率空间分布研究

采用7种插值方法(反距离权重法、径向基函数法、全局多项式法、局部多项式法、普通克里金法、泛克里金法、经验贝叶斯克里金法)对小海子灌区(南疆典型灌区)土壤含水率进行空间分布特征评估。结果表明:(1)研究区表层土壤含水率介于4.99%~24.99%,变异系数为27.6%,属于中等变异,且具有中等的空间自相关性,指数模型拟合变异函数的效果较好。(2)对于同时受结构性因素与随机性因素影响的小海子灌区,将确定性插值径向基函数法应用于土壤含水率插值的精度较高。(3)通过对灌区表层土壤含水率空间分布图的分析,发现小海子灌区春播前土壤含水率在空间上呈现出西南高、东北低的规律,且受地下水位及灌溉措施影响较大;表层土壤含水率大于15%的面积占总面积的64.9%,从整体上看,灌区西南部与中部的土壤含水率已达到播种要求,东北部地区达到“干播湿出”的播种要求,灌区可安排相应的春播活动。
