Effects of planting densities on canopy apparent photosynthesis, canopy structure and yield of cotton drip-irrigated under the mulch in Xinjiang
种植密度对新疆膜下滴灌棉花群体光合速率、冠层结构及产量的影响

The field experiments on the effects of 3 planting densities on the canopy apparent photosynthesis,canopy structure and yield of cotton drip-irrigated under the mulch were conducted in earlier harvest area of North Xinjiang.The results indicate that the optimum population density of the cotton is 240000 plantlets/hm2,under which the canopy structure,canopy apparent photosynthesis,leaf index,dry matter accumulation and distribution and lint yield of cotton are better than those under other densities.
