黄瓜定植前后有很多工作要做,这里主要介绍基肥的施用和苗期的管理,要做到六个到位。一是解决土壤盐渍化要到位。土壤盐渍化是老旧大棚的通病,具体表现是返盐。作物生长不良,生理性病害增多,产量下降。改良盐渍化土壤的有效办法目前还不多,无非是增施有机肥和生物菌肥,减少化肥使用量,轮作换茬,引淡水压盐。最为实际有效的方法应是引淡水压盐,即在黄瓜定植前深翻地做垄,用大水漫灌一次,土壤中的盐分能随水渗入地下水中,从而达到减少土壤含盐 Before and after cucumber planting a lot of work to do, here mainly introduces the application of basal fertilizer and seedling management, to achieve six in place. First, to solve soil salinization to be in place. Soil salinization is a common problem in the old greenhouse, the specific performance is back to salt. Poor crop growth, physiological diseases increased, the decline in production. There are not many effective ways to improve salinized soils yet. They are nothing more than organic fertilizers and biological fertilizers, reducing the amount of chemical fertilizers, shifting crops and shifting water pressure salt. The most practical and effective method should be dredging water pressure salt, that is, deep cupping before planting curtilage ridge, flood irrigation with water once, soil salt with water into the groundwater, so as to reduce soil salt
