本试验研究了水稻“三控”施肥技术氮肥调减施氮量及施肥时期对水稻产量、病虫害发生及经济效益的影响。结果表明:水稻“三控”施肥技术调减施氮量,减少基蘖肥比例和推迟分蘖肥施用时期,能有效地控制苗峰,提高成穗率,增加穗粒数,提高结实率,减轻病虫害的发生,达到增产增收的目的。
This experiment studied the rice “three control ” fertilization technology of nitrogen and reducing nitrogen application rate of fertilizer on the yield, pests and diseases and economic benefits. The results showed that the rice “three control” fertilization techniques could reduce the amount of nitrogen application, decrease the proportion of base tiller and tillering, and control the application of tillering fertilizer effectively, control the seedling peak effectively, increase the percentage of ear to ear, increase the number of grains per spike, and increase the seed setting rate , Reduce the occurrence of pests and diseases, to achieve the purpose of increasing production and income.
