一、推广杂交棉的好处棉花和其它作物一样,由两个或两个以上遗传性不同的品种进行杂交,所得的杂交种潜伏着巨大的内部矛盾性,故杂交种棉花表现出旺盛的生活力,长势壮、发育早、抗逆性强、产量高、品质好。这就是“杂种优势”。利用杂种优势,积极推广杂交棉花,可以很快的提高产量和改进纤维品质,是一个多快好省地办法。 First, the benefits of promoting hybrid cotton Cotton, like other crops, by two or more hereditary varieties of hybrids, the resulting hybrid lurking huge internal conflicts, so hybrid cotton showed strong viability , Growing strong, early development, strong resistance, high yield, good quality. This is the “heterosis.” The use of heterosis, the active promotion of hybrid cotton, can quickly improve the yield and improve fiber quality, is a much faster and better way.
