摘  要:
田间试验研究了3个水平的种植密度(21万株/hm2、24万株/hm2、27万株/hm2)对膜下滴灌棉花群体光合速率(CAP)、冠层结构及产量的影响。结果表明北疆棉区适宜播种条件下,24万株/hm2密度的群体冠层结构优于其他密度,生育后期仍可保持较高CAP,叶面积指数高值持续期进入早、持续时间长,光合物质累积多且分配到生殖器官中的比例大,皮棉产量较高。

摘  要:
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.
