在毛主席革命路线指引下,我们在水稻杂种优势利用,特别是不育系的繁殖方面,做了一些工作,取得了较好的成绩。1975年4.81亩夏季不育系繁殖田,共收不育系种子545.4斤,平均亩产113斤,其中2.4亩的一丘总产363斤,单产高达151斤。我们主要抓了以下技术措施:(一)稀播壮秧,适龄插秧我们根据不育系生育期短等特点,首先抓住了培育壮秧,适龄插秧这一关健措施,播前进行晒种和严格消毒,亩播60斤(为防止鸟雀危害,在两叶期前,用薄膜进行了短期覆
Under the guidance of Chairman Mao’s revolutionary line, we have done some work in rice heterosis utilization, especially in the breeding of sterile lines and have achieved good results. In 1975, 4.81 mu of summer CMS breeding field received a total of 545.4 kg of CMS seeds, with an average yield of 113 kg per mu, of which, a total yield of 363 kg per mu for 2.4 mu and a yield of 151 kg per mu. We mainly focus on the following technical measures: (A) thin sowing seedlings, age-appropriate transplanting We based on the CMS characteristics such as short duration, first of all, to seize the strong seedling cultivation, age-appropriate transplanting this key health measures before sowing And strict disinfection, mu sowing 60 pounds (to prevent bird damage, in the two leaves before the film was short-term cover
