本试验研究了不同整枝方式及不同密度对西瓜种子产量的影响,以为获得种子的高产提供依据。一、材料和方法试验分两个年度进行。 1985年在济南市长清县良种场进行,以中育6号为材料。在行距为1.8米,株距为0.6米,每亩种植617株的相同密度下,采取了四种不同的整枝方式:只留主蔓,除去全部侧枝(下称单蔓整枝);留主蔓及基部一侧枝(下称双蔓整枝);留主蔓及 This experiment studied the different pruning methods and different density on the yield of watermelon seeds in order to obtain the basis for the high yield of seeds. First, materials and methods The experiment is divided into two annuals. In 1985, Changqing County, Jinan City, good seed field to Zhongyu 6 as material. Four different pruning methods were adopted at the same density of 1.8 m in row spacing, 0.6 m spacing and 617 lines per acre. Basal side of the branch (hereinafter referred to as double vine pruning); stay Lord Man
