在武运粳8号高产栽培中,适期、适量施用磷、钾肥,有利于秧苗生长,减少无效分蘖,控制高峰苗,提高成穗率,有利于改善中后期群体条件,培育壮秆大穗,提高抗逆性,增加抽穗至成熟阶段干物质生产量,协调库、源关系,是构造武运粳8号高产群体的重要条件和有效调控手段。 In the high-yielding cultivation of Wuyunjing 8, Phosphorus and Potash fertilizers were applied at the proper and proper levels for the growth of seedlings, reducing ineffective tillers, controlling the peak seedlings and increasing the percentage of spikelets, improving the population condition in middle and late stage, , Increasing the resistance, increasing the dry matter production from heading to maturity, and coordinating the relationship between the source and the sink, is an important condition and an effective regulatory means for constructing the high-yielding population of Wuyunjing 8.
