摘　　要：以苏梦6号小果型西瓜为试验材料,研究了不同种植密度和整枝留果方式对小果型西瓜大小、产量和品质的影响。结果表明:不同种植密度和整枝留果方式对西瓜果实的大小、产量和收益均产生了很大的影响,但对品质的影响相对较小;西瓜的单果重随着株距的加大而逐渐增加,随着留果数的增加,西瓜单果重均呈现出显著的下降趋势,在留蔓数和留瓜数均相同的处理条件下的单果重没有明显的差异;西瓜产量随着株距的增加而逐渐下降,随着留果数的增加,产量有极显著的提高;各个处理的相对收益随着株距的增加而逐渐减少,随留果数的增加而提高,相对收益呈现出先增加后减少的趋势。The small-fruit watermelon“Sumeng 6”was taken as the experimental material,and the effects of different planting densities and pruning and fruit retention methods on the size,yield and quality of small-fruit watermelon were studied.The results showed that different planting densities and pruning methods had a great impact on the size,yield and income of watermelon fruit,but had a relatively small impact on the quality.The single fruit weight of watermelon gradually increased with the increase of plant spacing.With the increase of the number of preserved fruits,the single fruit weight showed a significant decline.Under the condition that the number of preserved vines and preserved fruits per unit area was the same,the single fruit weight had no significant difference.Watermelon yield decreased gradually with the increase of plant spacing.The yield increased significantly with the increase of fruit number.When the number of melons per unit area was the same as the number of vines,the relative income showed a change of first increasing and then decreasing with the increase of the number of preserved fruits.
