【Abstract】 The effects of different planting density and different fertilizer levels on yield and main characters of new cotton variety Ezamian 34 were studied. The results showed that the highest lint yield of 1 907.1 kg/hm~2 in the middle soil fertility could be obtained when the density was 27 thousand plants/hm~2 and the N,P2 O5,K2 O application amounts were 210 kg/hm~2,105 kg/hm~2,165 kg/hm~2.更多还原
