近年来,杂交水稻早熟高产组合的选育成功,解决了早、晚稻不同熟期组合的配套问题,为实现双季杂交稻亩产过吨粮,促进农业生产的大发展,开辟了新的途径。为了探讨双季杂交稻亩产吨粮的高产规律及综合配套栽培技术,1985年春,我们在社溪乡古陂村的新建、田段、排上、桥头、中岭等五个村民小组81户农户的责任田上,早稻选用威优35,晚稻选用威优6号,建立了105.94亩双季杂交稻亩产吨粮的高产栽培示范样板。现将栽培技术总结如下: In recent years, the hybridization of early maturity and high yield of hybrid rice has been successfully carried out, which has solved the matching problems of early maturity and late maturity, and opened up a new way to realize the per ton of grain yield per mu of double-crop hybrid rice and promote the great development of agricultural production . In order to investigate the high-yielding law of double-cropped hybrid rice per mu of grain yield and its integrated cultivation techniques, in the spring of 1985, we organized 81 villagers groups of five villagers groups in the newly built Kunshan Village, Tianzhu, Pai Pai, Qiaotou, Zhongling, Responsibility of farmers Tian, ​​early rice selection Granville 35, late rice selection Weiyou 6, established 105.94 acres of double crop hybrid rice yield per ton of high-yield cultivation demonstration model. Now cultivation techniques are summarized as follows:
