摘  要:
硫酸钾镁肥是一种天然的矿质肥料,能提供钾、镁、硫等养分元素。为明确硫酸钾镁肥在水稻上的施用效果,采用大田试验方法研究了不同硫酸钾镁施用量对水稻产量和土壤养分的影响。结果表明,施用硫酸钾镁肥对水稻有增产作用,增产幅度为0.8%~13.9%,最高产量可达11.58 t/hm2,比施用硫酸钾增产4.7%;硫酸钾镁肥可以有效减缓有机质分解,缓解土壤酸化,提高土壤有效总氮、磷、硫含量,增强水稻吸收利用氮磷钾等营养元素的能力。

摘  要:
The potassium and magnesium sulphate is a natural mineral fertilize,providing potassium(K), magnesium(Mg), sulfur(S) nutrients for crop growth. To illustrate effects of applying the potassium and magnesium sulphate fertilizer on rice field, studies were made with two different fertilization varieties and three levels of treatment. The results showed that applying the potassium and magnesium sulphate had a significant role in rice production. The yield increased from 0.8% to 13.9%. The maximum output is 11.58 t / hm2with an increase of 4.7% more than that of the potassium sulfate. It can slow down decomposition of organic matter, ease soil acidification, effectively improve the content of mineral elements in soil and enhance the ability of rice to absorb the N, P, K, Ca, Mg and S and other nutrients.
