我所的育种工作是根据本地区各个时期生产发展的需要而进行的。随着良种的推广和应用,使全区晚粳品种实现了四次改革,基本上做到了每五、六年更换一次。1954年以前,我区粳稻品种复杂,产量不高。在农业互助合作运动以后,迅速推广了八五三、四一二等良种,使水稻大面积亩产由400多斤 My breeding work is based on the needs of the development of production in various periods in the region. With the popularization and application of elite varieties, the four varieties of late japonica varieties have been implemented in the whole region, and basically the products have been replaced every five or six years. Before 1954, our region had a complicated variety of japonica rice and its yield was not high. After the agricultural cooperation and cooperation movement, the rapid promotion of 853, 412 and other elite varieties made the large-area rice yield increase from 400 kilos
