沿江圩区是安徽省主要水稻产区,自六十年代以来,双季稻发展较快,一部分地少人多的地区则实行“双三熟制”。究竟“稻麦两熟”还是“双三熟”制好呢?1978年秋季至1981年我们在公徽省含山县农科所进行了稻田不同熟制增产效果的对比试验,现将试验结果及其经济效益简介如下。 The polder area along the Yangtze River is the main paddy producing area in Anhui Province. Since the 1960s, double cropping rice has developed rapidly and some areas have fewer people and cultivated land. In the autumn of 1978 to 1981, we carried out a comparative experiment on the effects of different cooked and increased yields of paddy field in Hanshan County, Anhui Province, and compared the results of these tests with those of “Shuangsan Shu” The economic benefits are as follows.
