1984年我县从湖南省引入几个杂交早稻组合,进行适应性试验,以探索早稻高产的新途径。全县杂交早稻共试种730亩,其中威优64种植450亩,威优35种植195亩,汕优16种植90亩。通过第一年试种,初获成功。现将试种情况简单总结如下。据调查,杂交早稻无论在泽雅山区或永强浜海种植,无论是作绿肥田或作迟熟春花田后作,都比当地当家迟熟品种竹科2号增产。在试种的五个区九个片中,四个区八个 In 1984, the county introduced several hybrid early-rice combinations from Hunan Province to carry out adaptive experiments to explore new ways for high-yielding early rice. The county hybrid rice planted a total of 730 acres, of which Weiyou 64 planted 450 acres, Weiyou 35 planted 195 acres, Shanyou 16 planted 90 acres. Through the first year of trial planting, first success. The trial situation is now briefly summarized below. According to the survey, early hybrid rice in both Zaigaoshan or Yongqiang Hamam planting, either for green manure or late spring for the Chunhua after the crop, than the local late maturing varieties bamboo Branch No. 2 yield.
