近年来,随着高效设施农业的发展,各地温棚蔬菜种植的规模不断扩大,但由于长时间使用、种植,土壤的酸化问题变得越来越严重。据调查,多年种植的温棚土壤pH值<5.5的占29.4%,pH值<6.0的达50%。蔬菜温棚土壤的酸化,不但破坏了棚内土壤的结构和肥力,而且严重影响了温棚种植的产量和品质,制约了农村经济的可持续发展。
In recent years, with the development of highly efficient facility agriculture, the scale of greenhouse cultivation in various places has been expanding. However, due to prolonged use and cultivation, the acidification problem of soil becomes more and more serious. According to the survey, many years of cultivation of greenhouse soil pH value of <5.5 accounted for 29.4%, pH <6.0 up to 50%. Vegetable acidification of the greenhouse soil, not only destroyed the greenhouse soil structure and fertility, but also seriously affected the yield and quality of greenhouse cultivation, restricted the sustainable development of rural economy.
