摘要
本文综述了1986年底以来进行的亲本生育特性观察、父本栽插方式、生长激素应用、稻粒黑粉病防治等有关试验研究结果及其对改进我省制种技术,提高制种产量,扩大制种面积和实现全省杂交稻种子自给所起的重要作用.1990年全省制种16.9万亩,实施了以"一二三"工程为核心的综合配套技术措施,虽遇不利气候条件的影响,但仍获得亩产118.06公斤的较好收成,总产达1995.3万公斤.与1986年相比.制种面积扩大178.96%,单产提高11.79%,总产增加212.0%.全省杂交稻种植面积由1987年的1024.2万亩扩大到1991年的1600.0万亩(计划面积),而用种自给率却从49.9%提高到99.76%,基本上实现了我省杂交稻种自给的目标.
During the years that have passed since the end of 1986, a series ofexperiments as Parents growth regularity observation, Male parent planting form,Growth hormone application & Rice Kernel Smut controls etc. completed bythe Cooperation Group of Anhui Hybrid Rice Seed Production had played an im-portant role in improving seed production techniques, increasing seed productionyield, expanding seed production area and realising seed self-sufficient through-out the province. In 1990, the seed production area of the province arrived at169-000 mu, and the comprehensive technical measures which take‘1 2 3’project asprinciple part have been carried out to obtain good harvest(118.06 kg per mu) un-der adverse climate condition, and then the total output come up to 19593000 kg.In comparison with 1986, the seed production area expanded by 178. 96%, the yieldper unit area rose by 11.79%, and the total output went up by 212. 0%. The areaof hybrid rice has now expanded from 10242000 mu (1987) to 16000000 mu (1991. p-lanned area) in the province, and yet the seed self-sufficient rate increased from49.9% to 99.78%, becoming self-sufficient basically in bybrid rice seed.
