摘　　要：试验研究了不同种植密度、不同施肥水平对棉花(Gossypium spp.)新品种鄂杂棉34的产量及主要性状的影响。结果表明,中等肥力田块,鄂杂棉34在密度2.70万株/hm^2,施肥水平N 210 kg/hm^2、P2O5105 kg/hm^2、K2O 165 kg/hm^2时,皮棉产量最高,为1 907.1 kg/hm^2。The effects of different planting density and different fertilizer levels on yield and main characters of new cotton variety Ezamian34were studied.The results showed that the highest lint yield of1907.1kg/hm2in the middle soil fertility could be obtained when the density was27thousand plants/hm2and the N,P2〇5,K20application amounts were210kg/hm2,105kg/hm2,165kg/hm2.
