我们经过多年的实践,在制种体系建设、制种技术操作规程方面摸索出一些经验。一、建立稳固的制种基地栖霞县是从1959年开始试制玉米杂交种的,1963年繁殖推广自成体系配套繁殖,1966年全县实现杂交种化。现在常年玉米制种面积1.5万亩,总产杂交种300万公斤,全部达到国家一级标准。
After years of practice, we have worked out some experiences in seed production system construction and seed production techniques and procedures. First, the establishment of a solid base for seed production Qixia County is from 1959 trial corn hybrids, 1963 breeding propagation system supporting reproduction, the county in 1966 to achieve hybridization. Now perennial corn seedling area of 15000 mu, total hybrids 3000000 kilograms, all reached the national standard.
