去年秋种时,我们在颛桥公社中沟大队三队进行了夏熟作物的施肥技术承包。实践证明,这种形式能加速试验—示范—推广的进程。经土壤普查,中沟大队土壤有效磷含量较低,平均为8,7ppm(P)。去年夏熟作物磷肥试验曾获得明显的增产效果,因此承包的第一条施肥措施就是夏熟作物普遍增施磷肥,共用了7500斤磷肥,比去年增加了5000斤。第二条施肥措施就是根据当地三麦生产上挥发性氮肥多次追施、面施的习惯,而推广了三麦分层施肥法。
Autumn last autumn, we Zhuanqiao commune in the ditch in the three teams carried out summer fertilizer fertilization technology contract. Practice has proved that this form can speed up the experiment - demonstration - promotion process. After soil census, the content of soil available phosphorus in Zhonggou Brigade was low, with an average of 8,7 ppm (P). Last summer, summer crop phosphorus fertilizer test has been significantly increased yield, so the contracting of the first fertilization measure is the summer crop generally increased phosphorus fertilizer, share of 7500 kg of phosphate fertilizer, an increase of 5000 kg more than last year. The second fertilization measure is based on the local Sanmai production of volatile nitrogen fertilizer chase, face the habit of promoting the three wheat stratified fertilization method.
