杂交水稻生产潜力大,对促进粮食增产起积极作用.由于对杂交稻需肥特性认识不清,各地反映其需肥量大,影响它的推广.国内对杂交稻施肥技术研究,虽有一些报导,但偏重于施肥量和施肥时期的单项试验,尚缺乏全面系统的科学数据.本试验将施肥量和施用方法综合设计,从不同生育时期不同部位的需肥动态,来研究其需肥特性和施肥技术,为杂交稻省肥高产施肥提供依据.
Hybrid rice has great potential for production and plays a positive role in promoting grain yield. Due to the unclear understanding of the characteristics of hybrid rice to be fertilized, the demand for hybrid fertilizers has been greatly affected throughout the country, affecting its popularization. , But the emphasis on the amount of fertilizer and fertilization period of a single test, the lack of comprehensive and systematic scientific data.This experiment will be the amount of fertilizer and application methods integrated design, from different parts of different growth stages of the dynamic needs of fertilizer to study the need for fertilizer characteristics and Fertilization technology for high yield fertilization of hybrid rice provide the basis for fertilization.
