我从1973年开始用“三圃”法搞小麦良种提纯复壮,取得了较好的增产效果,比未提纯的平均增产5～10%。我体会,搞好小麦提纯复壮要抓好“早、准、快、易”四个字。 “早”即早抓。为了保持品种的优良种性,一个新品种开始推广就抓保纯,不要等到混杂退化后再抓。早抓容易识别混杂的植株,节省时间,简化“三圃”程序。
I started in 1973 with the “three nursery” law of wheat seed purification purification and rejuvenation, and achieved a better yield, compared with no purification of the average increase of 5 to 10%. I understand, do a good job of purification and rejuvenation of wheat “early, accurate, fast, easy ” four words. “Early ” that is caught early. In order to maintain the good breed varieties, a new breed began to promote grasping Paul pure, do not wait until the hybrid degeneration and then caught. Early caught easy to identify hybrid plants, save time, simplify “three nursery ” program.
