含盐量高的土壤种菜关键是栽不活苗,且苗生长缓慢,植株瘦弱,产量低而不稳。在盐碱地种蔬菜,应采取以下措施。一、改良盐碱地目前有冲水洗盐、压盐、使用盐碱丰、增施有机肥、耕地晒地等措施。一般含盐量超过0.3%的土壤必须采取改良盐碱地措施,含盐量低于0.3%的土壤要增施有机肥,提高土壤肥力。二、改良土壤结构提高土壤供肥能力,必须增施有机肥料,深耕晒地。要求
The key to planting soil with high salinity is planting seedlings, and the seedlings grow slowly, the plants are emaciated, the yield is low and unstable. In saline soil vegetables, should take the following measures. First, the improvement of saline and alkali current flushing salt washing, pressure salt, the use of salt and alkali abundance, the application of organic fertilizer, cultivated land drying and other measures. In general, soil with salinities exceeding 0.3% must take measures to improve saline land. For soils with salt content less than 0.3%, organic fertilizers should be added to improve soil fertility. Second, improve soil structure Improve soil fertility, organic fertilizer must be increased, cultivating sun. Claim
