在湖南西瓜生长前期低温、多雨、寡照 ,后期高温、干旱的气候条件下 ,对栽培密度与整枝方式、播种期、有机肥种类与用量等栽培因子对少籽西瓜产量和品质的影响进行研究的结果表明 :在海拔 30 0m左右的平原和丘陵区 ,肥力中等的砂质水稻土上 ,少籽西瓜适宜播种期为 3月中下旬到 4月初 ,栽培密度为 60 0株 /667m2 ,整枝方式为双蔓整枝较适宜。有机肥可明显提高少籽西瓜的产量和品质 ,有机肥用量至少应占总用氮量的 30 %以上 ,栽培少籽西瓜才能获得较好的效果。有机肥中菜籽饼最好 ,其次为鸡鸭粪 ,猪粪渣较差 The effects of planting density, pruning methods, sowing date, types and amount of organic manure on the yield and quality of seedless watermelon were studied under the conditions of low temperature, rain, low light and high temperature and drought in the early growing stage of watermelon in Hunan Province The results showed that suitable sowing dates of juvenile watermelon were in medium and late March to early April in the plains and hilly areas at an altitude of 300 m and sandy soil with medium fertility. The planting density was 60 0/667 m 2 and the pruning pattern was Double vine pruning more appropriate. Organic fertilizer can significantly improve the yield and quality of seedless watermelon, organic fertilizer should account for at least 30% of the total nitrogen, cultivation of seed watermelon in order to obtain better results. Organic fertilizer in the best rapeseed cake, followed by chicken and duck dung, pig dung poor
