我省杂交水稻的研究、示范推广及生产应用曾一度形势喜人,为我省粮食增产作出了一定的贡献,在全国可算是较好的省区之一.但近年来我省杂交水稻无论是面积或单产发展速度都很缓慢,尤其是杂交制种质量不高、产量一直徘徊不前,已成为我省进一步发展杂交水稻的重要障碍。据1982年底农牧渔业部召开的“全国杂交水稻会议”统计,全国18个省区杂交制种产量,北方稻区4.51万亩杂交粳稻制种田,平均单产255斤,南
In our province, the research, demonstration, popularization, production and application of hybrid rice have been enjoying gratifying situation for some time, which has made some contribution to grain yield increase in our province and can be regarded as one of the better provinces and autonomous regions in China. However, in recent years, Or the rate of development of yield is very slow, especially the quality of hybrid seed production is not high, the output has been stagnant, has become an important obstacle to the further development of hybrid rice in our province. According to the “National Hybrid Rice Conference” held by the Ministry of Agriculture, Animal and Animal Husbandry in late 1982, the output of hybrid seed production in 18 provinces and autonomous regions across the country was 4.51 million mu of hybrid japonica rice in the northern rice planting area with an average yield of 255 kg
