新型加硫尿素在油料作物中施用效果研究

EFFECT STUDY ON NEW TYPE SULFUR COATED UREA IN OIL-CROPS

采用硫磺粉和高分子粘结剂包裹尿素制备新型加硫尿素产品,并对新型加硫尿素(US)进行了2 a的田间应用试验。试验结果表明,施硫可以提高作物产量和作物品质,其中产量增幅黄豆为9.9%～18.2%、花生为3%～14.9%、油菜为6.6%～9.6%;作物蛋白质含量增幅花生为1.3%～2.6%,黄豆增加极微,油菜籽为1.9%～2.9%;花生和油菜籽含油率提高1%～2%,对黄豆含油率影响不大。

The new type sulfur coated urea（US） had been prepared by coating material,which was prepared by sulfur powder and organic polymer.The new type sulfur coated urea had been applied in the field for two years.The test results show that US can improve crop yield and quality of crops,of which the yield of soybean increases for 9.9% to 18.2%,peanuts for 3%～14.9%,rapes of 6.6%～9.6%;protein content of peanuts increases for 1.3%～2.6% and soybean for little,rapeseed for 1.9%～2.9%;oil content of peanuts and rapeseed increases for 1%～2%,soybean oil content not to much.
