摘要： Planting density is important for a high yield and quality of cotton, but still little is known about its effects on seed yield and fiber quality in Anhui province, China A field experiment was carried out with two varieties (Wankemian-1 and Wanmian-191), and five planting densities (D1, D2, D3, D4, D5). Results showed that the boll number per plant and boll weight decreased significantly with increasing planting density. The highest yields of Wanmian-191 and Wankemian-1 were 3591.0 and 3504.5 kg ha(-1) in D2 and D4, respectively. It was estimated that the planting densities in Wanmian-191 and Wankemian-1 for the maximum seed yield were 79000 and 115000 plants ha(-1), and the corresponding yields were 3610.3 and 3513.2 kg ha(-1), respectively. Suitable planting density increased the seed yield mainly by regulating the boll number per unit area and boll weight. Although the fiber quality was better for Wanmian-191 and Wankemian-1 under the planting density of 90000 and 79000 plants ha(-1), in order to obtain high seed yield, quality and economic benefits, the optimal planting densities are 79000 and 115000 plants ha(-1), respectively. There results will provide guideline for planting density to maximize yield and quality of cotton production in Anhui, China.
