玉米种整穗收购方法简便,优点多。它是防止假劣种子,提高种子质量的好办法。一是能够剔除因隔离不严串粉后有花粉直感的果穗和杂粒。二是可以根据穗型、轴色、粒型、粒色去掉杂穗、杂粒及掺入混入的杂交种子F_2和父本自交系。三是可以摒弃因后期去雄不及时造成的顶端自交小粒。四是可以减小分散加工工序,减少混杂机会,方便去杂,节省时间和劳力,缓解用工多与秋季农忙的矛盾。整穗收购直接供应种穗,或实行统一脱粒供种,可防止机械混杂。五是整穗收购可为实行果穗贮藏、提高种子质量创造条件。在空气相对湿度一般低于75%的北方,整穗贮藏,子粒中的水分可经疏松的穗轴散出,穗轴中的糖分等营养物质,则可继 Whole-grain corn acquisition method is simple, many advantages. It is a good way to prevent counterfeit seeds and improve the quality of the seeds. First, to be able to remove the insignificant string of pollen after the direct sense of the ears and grains. Second, according to the panicle type, axial color, grain type, grain size to remove the hybrid spike, hybrids and mixed with the hybrid seeds F_2 and male inbred lines. Third, you can get rid of due to the latter part of the cockroach caused by the top self-small particles. Fourth, we can reduce the dispersion of processing operations, reduce the chance of promiscuity, easy to miscellaneous, save time and labor, to ease the contradiction between more employment and autumn agricultural busy. The whole spike purchase direct supply of spikes, or the implementation of a unified threshing for seed, to prevent mechanical confounding. Fifth, the whole-grain acquisition can create conditions for implementing ear storage and improving seed quality. In the north of the relative air humidity is generally lower than 75%, the entire panicle storage, the water particles can be sparse loose spike, cob sugar in nutrients, you can continue
