夺取水稻高产,栽培往往会出现两个问题:一是如果施肥较多,苗期疯长,无效分蘖增多,形成所谓的“分蘖有余,成穗不足”;二是如果施肥不足,则后期早衰,穗粒矛盾加剧,形成所谓的“穗大有余,结实不足”。这大大地影响着杂交水稻产量的再提高。为协调这两大矛盾,我们利用麦壳、糠渣和稿秆在腐熟过程中消耗氮素的特性,控制无效分蘖;稿秆一经腐熟,还能提高土壤肥力,保证后期稳长健壮,延长功能叶寿命,促进粒 To seize the high yield of rice, cultivation will often have two problems: First, if more fertilizers, seedling soaring, invalid tillering increased, the formation of the so-called “tiller more than spike inadequate”; Second, if the lack of fertilization, the late premature aging, spike Aggravate the contradictions between the grain and grain, forming the so-called “big spike, stubborn enough.” This greatly affects the yield increase of hybrid rice. In order to coordinate these two contradictions, we use the properties of wheat straw, bran residue and manure to consume nitrogen in the decomposing process to control the ineffective tillers. Once the manure is decomposed, the soil fertility can be improved to ensure a stable and robust growth in the later period Leaf life, to promote grain
