沙土土壤沙性大,土质松散,粗粒多,毛管性能差,肥水易流失,其潜在养分含量低。这类土壤宜多施有机肥,如土杂肥、秸秆还田或种绿肥适时翻压培肥地力,逐步改善土壤性状。黏土这类土壤质地黏重,具有较强的保肥保水能力,但通透性能差,肥效较慢。故施用有机肥必须充分沤制腐熟,追施化肥应适当提早,并宜多吃少餐,适当减少施肥次数,后期忌过量多施氮肥,以防作物贪青迟熟。此外,还应勤中耕松土,提高土壤通气性。 Soil sandy soil, loose soil, coarse grains, poor capillary performance, easy loss of fertilizer and water, and its potential nutrient content is low. Such soil should be more organic fertilizer, such as Tuza Fei, straw or green fertilizer timely turn fertilization fertility, and gradually improve the soil properties. Clay soil texture sticky, with strong ability to retain fertilizer and water, but poor permeability, fertilizer slow. Therefore, the application of organic fertilizer must be fully compounded decomposed, topdressing fertilizers should be appropriate early, and should eat more meals, reduce the number of fertilizers appropriate, excessive excessive avoid nitrogen late to prevent late ripening of crops. In addition, it should also cultivate loose soil, increase soil aeration.
