摘要
1996～ 1 997年 ,对双季杂交稻盘育抛栽的适宜组合模式进行了研究。结果表明 :适宜于双季杂交稻盘育抛栽的新组合模式为早稻K青A/ 40 2配晚稻K优 1 7,在早稻抛栽 30～ 37.5万穴 /hm2 ,施纯N 1 2 0～ 1 5 0kg/hm2 ,晚稻抛栽 33/hm2 万穴 ,施纯N1 35kg/hm2 左右的情况下 ,双季产量可达 1 4 31 0kg/hm2 ,略优于双季稻手栽秧配套组合的产量水平 (1 386 0kg/hm2 ) 。
Suitable cultural modes of throwing seedling of hybrid rice in two crops were studied from 1996 to 1997.The results show that the best cultural mode is: variety combination “K Qing A/402”in the first crop and 'K You 17' in the second crop,300-375 thousand spots/hm 2 and 120-150 kg /hm 2 N in the first crop,330 thousand spots/hm 2 and about 135 kg /hm 2 N in the second crop. The total grain yield of two crops in this cultural mode of throwing seedling is 14130 kg/hm 2, higher than 13860 kg/hm 2 of manual planting seedling.
