Abstract试验研究表明,当早稻收获时间作晚稻才开始幼穗分化,即适宜早、晚稻出穗开花之间有60多天的时间,种植双杂间作稻就可获得好的收成,效果、效益都很显著。1992年用D 优287间汕优63,在达县永进乡的示范田中个别田块产量已达15t/ha,而盆地丘陵区适宜早、晚稻出穗开花之间的时间多数地区不到70天,种植双杂连作稻有困难。且双杂间作稻在抗灾增产,合理利用农村劳动力,提高稻田复种等方面优于双杂连作稻。因此,四川盆地丘陵区的中稻→冬水田在耕作改制中发展部分双杂间作稻是恰当的,其范围在巴中、盐亭、简阳一线以南海拔400m 以下的广大丘陵区。
Other AbstractExperimental results showed,when early rice was harvested,spikelet of late rice just began to differentiate,that is to say,more than 60 days were good for heading and flower of esrly and late rice,planting double-hybrid intercropping rice could reap a good harvest.The effect and benifit were significant.In 1992,the yields of a few fields amounted to 15t/ha when D-you 287 intercropped Shah-you 63 in demonstration fields in Yongjin of Daxian county.
