日光温室土壤消毒处理对番茄产量和品质的影响

Soil disinfection affects yield and quality of tomato in greenhouse

为了明确土壤消毒是否会影响番茄产量与品质,以粉果番茄汉姆七号为试材,采用高温闷棚的方法,研究不同土壤消毒方式(CK:不覆膜,不添加消毒剂;FM:仅覆膜,不添加消毒剂;SHN+FM:土壤覆膜+石灰氮;ML+FM:土壤覆膜+棉隆)对番茄产量和品质的影响。结果表明,采用SHN+FM进行土壤消毒时,番茄产量最高为9318.06 kg﹒667 m^(-2),与对照相比显著提高56.68%。SHN+FM处理下,番茄果实硬度、维生素C含量和可溶性糖含量均最高,分别为10.06 kg﹒cm^(-2)、70.74 mg﹒100 g^(-1)和4.49%,分别比CK提高17.11%、2.89%、44.84%。SHN+FM处理时番茄果实中的Mn元素含量最高,比CK显著提高了100.00%。综上所述,SHN+FM进行土壤消毒不仅可以增产,还能有效改善番茄品质。

In order to determine whether soil disinfection affect the yield and quality of tomato in greenhouse,the pink fruit tomato Ham No.7 was used as test material in this experiment.With high temperature stuffy shed,the experiment was conducted to study the effects of different soil disinfection methods(CK,no film covering,no disinfectant added;FM,only covered with film,without adding disinfectant;SHD+FM,soil mulching plus soil disinfectant lime nitrogen;ML+FM,soil mulching plus soil disinfectant micofume)on the yield and quality of tomato.The results showed that the maximum yield of tomato reached 9318.06 kg·667 m^(-2) when SHD+FM was used for soil disinfection,which was significantly increased by 56.68%compared with the control.Under SHN+FM treatment,fruit hardness,vitamin C and soluble sugar contents were the highest,which were 10.06 kg·cm^(-2),70.74 mg·100 g^(-1) and 4.49%,respectively,which were increased by 17.11%,2.89%and 44.84%compared with CK,respectively.The tomato fruit had the highest content of Mn in the SHN+FM treatment,which was significantly higher than CK by 100.00%.Therefore,lime nitrogen combined with film mulching(SHN+FM)can not only increase the yield of tomato,but also effectively improve the fruit quality of tomato.
