大棚内的土壤,由于不受降雨等自然条件的影响,随着栽培年限的增加,土壤盐渍化日趋严重,从而影响大棚蔬菜的产量和品质。 一、大棚内土壤盐渍化的原因 1.大棚内的土壤,因不受降雨条件的影响,土壤中的盐分不能随雨水流失或淋溶到土壤深层中去,而残留在土壤耕层内。 2.大棚栽培,由于灌水次数频繁,使土壤的团粒结构遭到
Because of the natural conditions such as rainfall, the soil in the greenhouse can not be affected by the natural conditions such as rainfall. With the increase of cultivation years, soil salinization becomes more and more serious, which will affect the yield and quality of greenhouse vegetables. First, the causes of soil salinization in the greenhouse 1. Soil in the greenhouse, because of the impact of rainfall conditions, the soil salt can not drain or leaching into the soil with rainfall, and remain in the soil layer. 2. Greenhouse cultivation, due to frequent irrigation, so that the aggregate structure of the soil was encountered
