Vegetable cultivation, with the increase of cultivation years, the degree of soil salinization in the greenhouse is aggravating, seriously affecting the yield and quality of greenhouse vegetables, reduce efficiency. Therefore, we must take precautions carefully. The specific reasons and practices are: First, the reasons for the vegetable greenhouse soil salinization According to years of research shows that the causes of vegetable greenhouse soil salinization mainly in the following aspects: 1, the environmental conditions of airtight. Soil in the greenhouse, due to the inhibition of greenhouse film, evaporation is small; not subject to natural conditions such as rainfall
