摘　　要：在露地简约化栽培条件下,研究不同栽培密度对无籽西瓜单瓜质量、产量及品质的影响。以‘雪峰花皮无籽’西瓜为供试品种,分别设置每667 m2150株(S1)、200株(S2)、300株(S3)和450株(S4)(CK)4个处理进行田间小区试验。比较在不整枝条件下不同栽培密度处理对西瓜单瓜质量、产量和品质的差异。结果表明,4种栽培密度处理下西瓜的单瓜质量和产量存在一定差异,品质无差异。不同栽培密度处理的单瓜质量随密度增加呈递减趋势,S1处理的单瓜质量最大,显著高于其他处理;产量随密度的增加呈先增后减趋势,S2处理的产量最高,显著高于S1和S4(CK)处理;可溶性固形物含量没有显著差异。露地简约化栽培无籽西瓜以每667 m^2 200株的栽培密度最佳,此密度产量增加14.68%,每hm^2投入种苗费减少4 500元,每hm^2增收12 150.36元,丰产性和经济效益最好。The purpose of this paper is to study the effects of planting density on watermelon fruit weight, yield and quality in open field. ＇Xuefeng Huapiwuzi＇ was used as the experimental material, 4 planting densities （S 1 ： 150 plants per 667 m2, $2 ： 200 plants per 667 m2, $3 ： 300 plants per 667 m2 and S4 ： 450 plants per 667 m2 （CK）） were set in this research , the single fruit weight, yield and quality of each treatments with leafy shoots retained were compared. The results showed that there were some differences in the weight and yield of watermelon under the 4 planting densities. The single fruit weight was in- creased with the planting density decreasing, the single fruit weight of S 1 was significantly higher than other treatments. The yield was first increased and then decreased with the increase of planting density, yield of $2 was the highest, which was significantly higher than that of S1 and $4 （CK）. The soluble solid content was found no significant difference among different treatments. In conclusion, the best planting density of seedless watermelon under simplified cultivation was 200 plants per 667 m2, in such condition, the yield increased by 14.68%, investment cost decreased by 4 500 yuan per hectare and income increased by 12 150.36 yuan per hectare, and the overall yield and economic benefit were highest.
