摘　　要：设置不施氮肥、分别施纯氮150、300、450、600kg/hm2和施纯氮300kg/hm2+鸡粪1500kg/hm2等6个处理,4次重复,研究不同氮肥施用量对油后棉产量的影响。结果表明:在中等肥力棉田、密度24000株/hm2的条件下,施纯氮300kg/hm2+鸡粪1500kg/hm2,能够明显地提高油后棉产量。Setting 6 treatments including non-fertilizer application,150,300,450,600 kg/hm2 in nitrogen fertilizer and one with 300 kg/hm2 in nitrogen fertilizer and 1 500 kg/hm2 in hen manure,adopted 4 repetition,studied the effects of application amount of nitrogen fertilizer on yield of cotton after preceding crop rape. The results showed that the treatment in which cotton field with medium fertility,24 000 plant per hectare in planting density,having 300 kg/hm2 in nitrogen fertilizer and 1 500 kg/hm2 in hen manure...
