黄岩县鼓屿公社十里铺大队1977年和1978年大面积种植杂交水稻,都获得好收成。1978晚季全大队种植630亩杂交水稻,平均亩产1,050斤,比1977年亩产871.5斤增产20.5%,其中11.976亩平均亩产1,327.5斤;最高的一丘1.67亩,平均亩产1,414斤。实现了晚稻单产和总产超历史,超千斤,超早稻。现将1978年杂交晚稻的主要技术经验归纳于下。一、选用高产稳产杂交组合汕优6号。两年来,我们通过不同组合比较试验和大面积示范种植,认为目前在生产上试用的杂交组合,以汕优6号表现最好。1977年39.19亩汕优6号,平均亩产1,012斤,比402.8亩南优2号和南优6号平均每亩增产156斤,增产率达18.2%。第四生产队对10个杂交组合对比试验结果,汕优6号亩产983.7斤,比 Shiyu commune, Shiyu commune, Huangyan County Brigade Shilipu 1977 and 1978, large areas of hybrid rice cultivation, have received a good harvest. In the late autumn of 1978, 630 mu of hybrid rice was planted in the entire brigade, with an average yield of 1,050 kg per mu, an increase of 20.5% over that of 871.5 kg per mu in 1977, of which 11.976 mu was 1,327.5 kg per mu. The highest mound was 1.67 mu with an average yield of 1,414 kg per mu. Realization of late rice yield and total production of ultra-history, ultra-jin, super-early rice. The main technical experience of late hybrid rice in 1978 is summarized below. First, the selection of high yield and stability of hybrid combinations Shanyou 6. In the past two years, we have experimented with different combinations and conducted large-scale demonstration planting. We think that the hybrid combination that is currently being tested in production is best performed by Shanyou No. 6. In 1977, 39.19 mu of Shanyou 6 had an average mu yield of 1,012 jin, an increase of 156 jin per mu compared with 402.8 mu of Nan You 2 and Nan You 6, with an increase rate of 18.2%. The fourth production team on the 10 hybrid combinations comparison test results, Shanyou 6 per mu 983.7 kg,
