摘要
在石灰性土壤上进行田间小区试验,结果表明,秸秆黄腐酸包膜尿素能满足水稻生长最大效率期对营养的要求,有利于有效穗的分化,提高结实率。等氮量试验平均增产9.6%,等重量试验平均增产7.4%。
Doing the field district experiment on the lime soil.The result indicates that stalk fulvic acid coated urea on rice can meet the requirements for nutrition when growing big efficiency issue most in rice.It is favorable to the division of the effective fringe.It raises the fecundity.The experiment of equal nitrogen amount increases yield 9.6% averagely.The experiment of equal weight increases yield 7.4% averagely.
