上海市青浦县农业科研究所所属农场退休种子员,70岁有余的傅佐敏对种子提纯复壮发表见解: 实行家庭联产承包责任制后,种子提纯复壮工作有所忽视,这是一大失策。要夺取高产,种子的好坏是关键,这是众所周知的。但引进一个优良品种能种植几年,知道的人就并不多了。据我30多年试验,若不采取提纯复壮措施,多则五六年,少则三四年,种子往往变成“一年纯、二年变、三年变成大花脸。”如果你继续种植,将会造成严重减产。什么叫种子的提纯复壮呢?提纯:就是将一个品种内的机械混杂和生物学混杂植株去掉,提高其品种的纯度;复壮:就是将品种种性纯化,恢复或提高原有的生产能力。提纯复壮是要采用一定的措施,使生产上不断地得到相对纯的、生活力强的、无混杂退化现象的种子过程。30年来,我对小麦扬麦1号、大麦早熟3号、沪麦4号、沪麦8
Qingpu County, Shanghai Institute of Agricultural Sciences belongs to the farm retired seed workers, more than 70-year-old Fu Zuomin Purification and Rejuvenation of the seed expressed the view: the implementation of household contract responsibility system, the seed purification and rejuvenation neglected, which is a big mistake. It is well-known that the key to winning high yields and the quality of the seeds is. However, the introduction of a good variety can be planted for a few years, people do not know much. According to my 30-year trial, if not to take measures to purify and rejuvenate, as many as five or six years, as little as three or four years, the seeds tend to become “a pure year, two years change, three years into a big face.” "If you continue Planting will result in serious cuts. What is the purification and rejuvenation of seeds? Purification: that is, to remove the hybrid machinery and biological hybrid plants within a variety and improve the purity of the varieties; Rejuvenation: Purification, restoration or improvement of original production capacity. Purification and rejuvenation is to adopt certain measures to make the production continue to be relatively pure, strong vitality, no mixed degradation of the seed process. In the past 30 years, I have been on the wheat Yangmai 1, barley precocity 3, Shanghai wheat 4, Shanghai wheat 8
