【摘要】 以常规抗虫棉鲁棉研28号为材料,在山东鲁西北棉区的临清市、商河县两地大田条件下纯作种植,研究施用盖顶肥对棉花产量的影响。结果表明,施用盖顶肥增产效果明显。尤以8月10日施用尿素150kg.hm-2处理,平均果枝达到13.9个,单株成铃14.3个,铃重6.5g,皮棉平均产量1317kg.hm-2,棉花后期生长稳健,秋桃比例增加且铃重增加,增产效果最佳。更多还原

【Abstract】 In order to study the effect of covered fat prevent premature senility,cotton cultivar Lumianyan No.28 was grown in linqin,Shanghe of Shandong Luxibei cotton region.The results showed that applying covered fat can improve the production.Especially applying 150 kg·hm-2 carbamide in august 10 can get the optimum production.It can increase the rate of the autumn cotton boll and the weight of cotton boll.Cotton grow steadyily at the late growth stage.The average of boll-bearing branch is 13.9 per plant,the ripe cotton boll is 14.3 per plant,the average weight of cotton boll is 6.5 g,and the average production is 1317 kg·hm-2.更多还原
