绿肥种植及翻压对日光温室土壤环境的影响

Effect of Green Manure Planting and Application on Solar Greenhouse Soil Environment

研究了日光温室休闲季节种植绿肥作物并翻压到土壤中,对土壤肥力和土壤酶活性的影响。结果表明：在日光温室夏季近2个月的休闲时期,种植三叶草能生产863 kg/667m^2的鲜草,种植大豆能生产1 500-1 800 kg/667m^2的鲜草,在下茬作物种植之前将绿肥翻压到土壤中,分析土壤指标发现,种植和翻压绿肥均能有效降低土壤盐分,提高肥力和改善土壤酶环境,是一种修复日光温室设施障碍一种可行的措施,其中以种植和翻压三叶草效果最佳,黄豆和黑豆之间差异不大。

Experiments were carried out to study the effect of green manure planting and application on soil properties and enzyme activities during free time in greenhouse.The results showed that clover can produce 863 kg/acre of fresh grass;soybeans can produce 1 500-1 800 kg/acre fresh during two months of free time in greenhouse.Before the following vegetables will be Cultivated,green manure was ploughed out.Result of analyzing the soil index indicated the green manure by plant or application can effectively reduce the content of soil salt,improve the soil fertility and increase the enzyme activity, was feasible measures of restoring soil obstacle in solar greenhouse. Among them, clover was the best green manure, soybeans and black beans was not the difference between.
