湿润灌溉下晚稻肥料运筹方式研究
Research on the Fertilizer Manage ment Approach of Late-rice under Moistening Irrigation
摘要
Abstract
Hybrid rice ‘Shengtaiyou 018’was used to investigate the water and fertilizer-saving cultivation technolo-gy. Under the condition of moistening irrigation and applied N 150 kg/hm2 ,through 6 fertilizer management pattern:NPK=1∶0. 5∶1 or 1∶0. 6∶1. 2 combined with base fertilizer(B)∶tillering fertilizer(T)∶earing fertilizer(E)=4∶3∶3、5∶3∶2 or 6∶3∶1. The influence of different fertilization methods on rice root、leaf group quality and yield formation,and their relation-ship were researched,and the relatively optimal fertilization technology was screened out. Results showed that:under the condition of this research,the fertilization pattern of NPK=1∶0. 5∶1 and B∶T∶E=5∶3∶2 or NPK=1∶0. 6∶1. 2 and B∶T∶E=6∶3∶1 ,may better regulate and control the rice to grow more reasonable roots and population leaf structure,and gain higher economic yield. It is the relative optimal fertilizing pattern in this experiment.关键词
