在最近召开的全国杂交水稻栽培科研协作会议上,浙江温州市农科所和河南农林科学院粮食作物所,利用旱地试种杂交水稻获得成功一事,被认为是杂交稻栽培技术的新发展。河南省1976年开始在旱地上试种麦茬稻(粳稻组合),1982年全省试种面积已达1.3万亩,一般单产6～7百斤,高的超过千斤。温州市农科所1979年开始在文成县用汕优6号作旱地栽培适应性试验,1980年扩大试种40亩,获得平均单产530.3斤的好收成。1981年扩展到永增、苍南、平阳、瑞安、单文等县,其中,单文县试种250余亩,有3亩平均单产721斤(其中 At the recently held National Cooperative Meeting on Cultivation and Research of Hybrid Rice, the successful application of dry hybrid rice cultivation in dry land was considered as a new development of hybrid rice cultivation techniques at the Agricultural Science Institute of Wenzhou City and the Food Crops Institute of Henan Academy of Agriculture and Forestry. Henan Province began to test wheat stubble rice (japonica rice combination) in dry land in 1976. In 1982, the test area of ​​the province reached 13,000 mu and the average yield was 6-7 kilograms per hectare, which was over 1,000 kilos. Wenzhou Academy of Agricultural Sciences in 1979 started using Wenyi County, Shanyou 6 for dry cultivation adaptability test, expanding the test in 40 acres in 1980, access to an average yield 530.3 kg of good harvest. In 1981, it was expanded to Yongzheng, Cangnan, Pingyang, Shui’an and Shanwen counties, of which, more than 250 mu were cultivated in Shanwen County, with an average yield of 721 kg in 3 mu
