本试验表明:杂交水稻应用三高一稳栽培法能有效地控制后期无效分蘖,大幅度提高成穗率。其中深水控蘖效果又优于超前晒田;在施氮肥方法上,不同化学氮肥施用比例早季(6:1:2.5:0.5)法、晚季以(5:1:3:1)法为好,同时适当提高栽插密度对早杂有明显的增产效应。
The experiment shows that: hybrid rice application of three high and one stable cultivation method can effectively control the late invalid tillers, significantly increase the rate of ear. Among them, the effect of deep-water control tillers was superior to that of advanced sun-shading. The rates of different chemical nitrogen fertilizers in early-season (6: 1: 2.5: 0.5) and late-season (5: 1: 3: 1) Well, at the same time appropriate planting density increased early yield significantly increased yield effect.
