聚丙烯酰胺缓释肥料的玉米肥效试验

PolyacryIamide made slow-release fertilizer's effects on Zea ways

新研制的缓释肥料具有环保、保持水土、改良土壤、提高肥料利用率和增加农业的经济效益等优点。试验结果表明,采用聚丙烯酰胺(PAM)生产的缓释肥料可以增产0 76%～12 82%,增加经济效益179 5～579元·hm-2,对玉米生长中后期的性状也有很大改善,是一种很有发展前景的新型缓释肥料。

The new slowrelease fertilizer protects environment,conserves soil and water,improves soil quality and increase effciency and economic benefits.The results of experiments show the yield can be increased by 076%～1282% and economic benefit can be increased by 1795～5790 yuan(RMB)per hectare by using the slowrelease fertilizer made from polyacrylamide(PAM).The fertilizer can also improve the characters of corn during its medium and later period of growth.It is a very promising new slowrelease fertilizer.[Ch,3 tab.7 ref.]
