早籼稻双季双直播种植模式探析

Discussion on Double Season and Double Live Planting Patterns of Early Indica Rice

以绍兴市农业科学研究院自主选育的早籼稻新品系绍籼122为试验材料,以中早39和金早47为对照,对早籼稻双季双直播种植模式进行试验。结果表明,绍籼122正季生育期与对照金早47相仿,产量与对照中早39相仿;翻秋生育期均比2个对照提早,产量均比2个对照增加;通过早、晚两季直播种植,绍籼122生育期可比对照提早5~9 d,产量可达13 500 kg/hm2以上。

Taking new early indica rice variety Shaoxian 122 which was independent bred by Shaoxing City Academy of Agricultural Sciences as the test material, and taking Zhongzao 39 and Jinzao 47 as controls, the Double-cropping and double-seeding model for early indica rice was conducted.The results showed that Shaoxing 122 was the same as CK 47, and the yield was similar to that in the control. The growth period of autumn was earlier than that of two control, and the yield was increased compared with the two. Through early and late planting direct seeding, Shaoxing 122 growth period was earlier than the control 5-9 d, and yield up to 13 500 kg/hm2 or more.
