在一定密度范围内,充分合理的利用父本花粉,最大限度的增加母本株数,是实现玉米制种高产更高产的关键。自推广玉米杂交种以来,为了提高制种产量,母父行比由2:1逐渐增加到6:1或10:2,这样母本株数是增加了,但同时也加大了父本散粉间距,授粉不佳。为了大幅度提高制种产量,探索制种高产途径,作者在多年试验研究的基础上,改革了传统的行比制种形式,设计了父本以点分布的制种形式,简称点父法,并与目前采用
In a certain range of density, using the parental pollen reasonably and maximizing the number of female parent plants is the key to achieve higher yield and higher yield of maize seeds. Since the promotion of maize hybrids, in order to increase seed production, the ratio of mother to father increased from 2: 1 to 6: 1 or 10: 2, so that the number of mother plants was increased but the spacing of male parents was also increased Poor pollination. In order to greatly improve the seed production and explore ways to seed production, the author based on years of experimental research, the reform of the traditional line of seed production, the design of the male parent to point distribution of seed production, referred to as the parent point, And with the current adoption
