砂质土壤砂粒多粘粒少,土体结构松散,漏水漏肥严重,土壤肥力低。科学施肥要把改良土壤放在首位,最大限度地提高肥料利用率,在单位面积土地上以最小的投入获得较高的经济效益。总结实践经验,砂质土壤施肥技术应从以下几个方面去做。 一、掺施泥肥。泥肥是沟、湖、河、塘中的肥沃淤泥及洪水淤积物,其中粘粒多砂粒少,是改良砂质土壤土体结构的好肥料,施泥肥要逐年进行,一般每年亩施2—3方为宜。前作收获后结合秋季翻地撒施,均匀混入土壤耕层20—30厘米处。 Sandy sandy grit has less clay, loose soil structure, serious leaking leakage and poor soil fertility. Scientific fertilization should put improved soil in the first place to maximize the utilization rate of fertilizer and obtain the higher economic benefit with the minimum investment on the unit area of ​​land. Summarizing practical experience, sandy soil fertilization techniques should be done from the following aspects. First, mixed with mud. Muddy fertilizer is a fertile silt and flood sediment in ditches, lakes, rivers and ponds. Less clay is composed of many grit and sand, which is a good fertilizer to improve the soil structure of sandy soil. Mud must be applied year by year. Generally, Mushi 2 -3 party is appropriate. After the harvest combined with the autumn turned to the soil, evenly mixed with 20-30 cm soil plow.
