为探索杂交稻制种对减轻不育系包颈、提早花时,提高异交结实,增加制种产量比喷施赤霉素更有效的激素配置。我们从1981年开始,连续6年对多种激素进行了不同的配置试验。虽有几个配置方案取得一些成效,但增产幅度都不太大。1986年我们引进了新型植物生长调节剂——“花调灵”,进行了小面积的对比试验。当年,比单喷赤霉素的每亩增产23公斤。1987年在镇江市种子公司主持下,在全市4个县进行了联
In order to explore the hybrid rice seed production to reduce the sterile neck of the package, as early as possible to improve the outcrossing, increased seed production than spray gibberellin more effective hormone configuration. Since 1981, we have conducted various configuration experiments for various hormones for six consecutive years. Although there are several configuration programs to achieve some results, but the rate of increase is not too large. In 1986 we introduced a new plant growth regulator - “Hua Tu Ling”, carried out a small area of the comparative test. That year, an increase of 23 kilograms per acre than single-spraying gibberellin. Under the auspices of Zhenjiang Seed Company in 1987, Lianhe was conducted in 4 counties in the city
