我场位于中卫县城北紧靠腾格里沙漠边缘的龙信滩,是全县有名的湖坑碱地。1980年以来着重抓了增施有机肥等技术措施,使小麦单产显著提高,总产成倍增加。通过四年实践,对比了几种有机肥的经济效益。1.圈肥。1980年以前曾采取多拉土、勤垫圈、勤起肥的作法,一个工能积2.2车粪,按社会工资1.65元计算,每车肥合0.75元,加上运到地里的工资0.25元,每亩上肥20车,成本达20元。但根据化验结果,猪圈肥(垫黄沙)中除有效磷比土壤高
My field is located in Zhongwei County, close to the edge of the Tengger Desert Long Beach, is the county’s famous lake pit alkaline. Since 1980, we have mainly focused on the technical measures such as increasing organic manures and have significantly increased wheat yields and doubled the total output. Through four years of practice, compared the economic benefits of several organic fertilizer. 1. Circle fat.
