摘要
以攻前保后施肥法和常规施肥法为对照,采用大区比较试验,研究了三控施肥法对抛栽早稻倒伏及产量的影响。结果表明:三控施肥法通过控制苗峰,增加群体通透性,控制病虫害发生,增加植株抗倒力,减轻倒伏,优化产量结构,提高经济系数,实现稳产、高产。本试验条件下,三控施肥法水稻产量达8 028.7 kg/hm2,较常规施肥法增产6.07%,增收11.3%。
The effects of three control fertilization on the lodging and yield of early rice with scattered-planting were studied using the comparative experiment. The results showed that the three control fertilization could control the seedling peak, improve the population permeability, reduce the diseases and insect pests, enhance the lodging resistance, optimize the yield structure, increase the economic coefficient, and realize stable and high yield. The yield of rice reached 8 028.7 kg/hm^2, which increased by 6. 07% than the conventional fertilization, and the income increased by 11.3%.
