摘要
通过盆栽试验,对大豆施用硫钙肥的效果进行了研究。结果表明,施用硫钙肥能显著增加大豆生物产量,增加土壤有效硫、交换钙含量,提高大豆籽实氮、硫、钙的含量,是盐碱土有效的改良剂。
Fertilizer efficiency of sulphur-calcium fertilizer was studied in soil of short sulphur and calcium with pot incubation test of soybean. The results showed that sulphur-calcium fertilizer could increase soybean yieid markedly and nitrogen, phosphorus and cal- cium content in soybean grain. Simuhaneously,it could improve effective sulphur and exchange calcium content in soil. sulphur-calci- um fertilizer was effective improvement agent of alkaline soil.
