我省自1982年大面积推广杂交棉以来,扩大建立了以杂交棉繁殖、制种为主体的良繁基地。逐步实行了“省繁、县制”的繁殖、制种体系,并总结推广了繁殖、制种高产技术经验,狠抓了繁殖、制种的纯度和质量。形成了良种“产、供、销”一条龙。两者通过“省繁、县制”的途径,相互连接互为整体,形成了一种新的棉花良繁体系,即“育、繁、推,产,供、销”一体化,保证了杂交棉的稳定发展,取得了一定的成绩和经验。一、杂交棉繁殖、制种的主要成绩 1、繁殖、制种技术的改进。在杂交棉种子生产基地中、繁殖、制种推行了“五改’技术措施,即一改以往的花期育性识别为芮期育性识别,提
Since the popularization of hybrid cotton in 1982 in large scale in our province, the province has expanded its establishment of a well-to-do base that mainly reproduces and produces hybrid cotton. Gradually implemented the “provincial Fan, county system” breeding, seed system, and summed up the promotion of breeding, seed production and high yielding technical experience, pay close attention to reproduction, seed purity and quality. Formed a seed “production, supply and marketing” train. Both of them are interconnected and integrated with each other through the means of “making the province prosperous and county-level” and forming a new system of cotton multiplication, that is, the integration of “breeding, multiplication, pushing, producing, supplying and selling” ensures the hybridization The steady development of cotton, has made some achievements and experience. First, hybrid cotton breeding, seed production of the main achievements 1, breeding, seed production technology improvements. In hybrid cotton seed production base, breeding, seed production implemented the “five changes” technical measures, that is, to change the recognition of flowering in the past as Rui fertility identification, mention
