大棚蔬菜施肥技术及土壤改良措施

Fertilization Technology and Soil Improvement Measures in Greenhouses

近年来,随着农业种植结构的变化,大棚蔬菜种植面积逐渐增大,满足了人们对蔬菜多样化的要求。但大棚内种植环境封闭,空气流动性差,表层盐渍化,造成土壤板结,长期种植易导致蔬菜产量、品质降低,病虫害加重。针对上述问题,本文探讨了大棚蔬菜的施肥技术原则及技术要点,防控大棚蔬菜亚硝酸盐积累及土壤酸化、板结等的具体措施,从而提高了大棚蔬菜的产量和品质,防止土壤酸化,增强土壤活性。

In recent years, with the change of agricultural planting structure, the planting area of greenhouse vegetable is becoming larger and larger, which meets people＇s requirements for vegetable diversification. Greenhouse has good heat preservation and light transmission performance, but because of the closed planting environment, poor air mobility, surface salinization, resulting in soil hardening, long-term planting leads to reduced yield and quality of vegetables, and increased pests and diseases. In view of the above problems, this paper discussed the technical principles and key points of fertilization for greenhouse vegetables, and the concrete measures for preventing and controlling nitrite accumulation, soil acidification and solidification of greenhouse vegetables, so as to improve the yield and quality of greenhouse vegetables, to prevent soil acidification and enhance soil activity.
