摘  要:
试验结果表明 ,培杂 2 75在肥力中等条件下 ,早稻采用旱育抛秧 ,以施N总量的60 %作基肥 ,2 0 %作分蘖肥 ,2 0 %作穗粒肥 ,可缓解群体与个体间的矛盾 ,减轻病虫害发生 ,防早衰 ,提高成穗率 ,穗粒结构较合理 ,容易获得较高产量。

摘  要:
Experiments showed that,under medium fertility,dry breeding and seedling throwing were applied in the early hybrid rice of Pei Zha 275.Applying the 60% amount of the total N as the base fertilizer,the 20% amount of the total N as the tillering fertilizer and the asme amount of the total N as the ear fertilizer,the contradiction between the population and individuality could be relieved,the plant diseases and insect pests could be reduced,early ageing could be prevented,the percentage of earbearing tiller could be raised up and the structure of the ear granules was more reasonable.As a result,higher output would be obtained.
