大棚土壤由于它所属空间的特殊性,多受到盐害。导致这一现象的主要原因在于棚内没有受到外界雨水的淋灌。使土壤中的盐分过多堆积在土壤表面,使土壤表面的盐分浓度不断升高。导致蔬菜农作物不能正常生长,给大棚种植代来不可估量的经济损失。在实践中总结出多种方法克服这一困难。主要通过对大棚内土壤营养结构的分析,以及对蔬菜对养分的需求加以分析举证。对大棚内土壤进行科学合理地土壤改造工作。
Due to the particularity of the space to which it belongs, the soil in the greenhouse is mostly harmed by salt. The main reason for this phenomenon is that the shed has not been affected by external rainwater. So that excessive accumulation of salt in the soil surface soil, so that the soil surface salt concentration rising. Leading to vegetables can not grow normally, to the greenhouse cultivation to incalculable economic losses. In practice, many methods have been summarized to overcome this difficulty. Mainly through the analysis of soil nutrient structure in the greenhouse, as well as the needs of vegetables on the nutrient analysis and proof. Soil in the greenhouse to carry out scientific and rational soil rebuilding work.
