- 摘要:
- 为促进花生高产栽培,在大田高产条件下,以珍珠豆型花生唐A8252为材料,研究了不同施钙量对花生干物质积累和产量的影响。结果表明:花生饱果数、单株干重、出仁率、荚果产量等均随着施钙量的增加而增加,但当施钙量超过150 kg?hm-2时,继续增加施钙量产量反而下降。主茎高、侧枝长等植株性状随着施钙量的增加而降低。因此,在施钙量150 kg?hm-2时可获得最优农艺性状指数和最高产量效益。
- Abstract:
- In order to promote high-yielding cultivation of peanut,the Spanish-type peanut variety Tang A8252 was used as materials,the effects of calcium application rates on dry matter accumulation and yield of peanut were studied under high-yielding field condition.The results showed that number of mature pods,dry matter weight per plant,ratio of shelled peanut and yield increased with the increase of calcium application.However,the above indexes of Tang A8252 did not increase then calcium application rates more than 150 kg?hm-2.While other plant characteristics decreased with the increase of calcium application,such asthe height of main stem,the length of lateral branch,etc.Therefore,the optimal agronomic character index and the highest yield benefit could be obtained when the amount of calcium was 150 kg?hm-2.
