- 摘要:
- 合丰25大豆品种在15、22. 5、30cm行距,播量66. 7、55. 6和44. 4万株/hm2 情况下,分别增产1. 4%、9. 04% 和23. 39% ,其中播量44. 4万株/hm2条件下,增产最高。在窄行密植条件下,随着密度的增加,单株有效荚、单株粒数、单株粒重减少; 密植后,大豆结荚部位上移,结荚主要集中在中、上部,以中部结荚高于上部结荚,下部结荚为最少,密度和行距不同对百粒重影响不大。在目前条件下,合丰25类型大豆品种的播量不应超过44. 4万株/hm2。
- Abstract:
- The seed yields of soybea n Hefeng 25 under row widthes 15, 22. 5, 30cm and seeding ra tes 66. 7, 55. 6, 44. 4 seeds Per m2 w ere respectiv ely 1. 4% , 9. 04% a nd 23. 39% hig her than that o f check. Amo ng o f tho se, seed yield under 44. 4 seeds per m2 was the highest. The number of pods, seeds and seed weight per plant reduced wi th th e seeding rate increasing. Under solidseeded planting , height o f low est pod increa sed, the pods w ere mainly dist ributed o n middle and upper sectio n o f stem, the number of po ds on middle sectio n was more tha n that on upper sectio n, and the low er section of stem had the least pods. The seeding rate and row width had no sig ni ficant inf luence to 100-seed w eight. In current soybean productio n, seeding ra te per m2 of Hefeng 25, a nd the ones simi lar to i t , sho uld not be mo re tha n 44. 4 seeds Per m2 .
