密度和品种及生长调节剂对籽用南瓜产质量的影响

为了大面积发展籽用南瓜种植业,最大限度地挖掘籽用南瓜的增产潜力,提高籽用南瓜单位面积的产量和质量,增加农民收入,探讨了不同密度、不同品种及生长调节剂等栽培措施对籽用南瓜产质量和经济性状的影响。结果表明:试验品种生育期差异不大,银辉2号和林口圆板的分枝性较弱,产量性状优良,是大面积种植的首选品种;种植密度以保苗15 000株.hm-2(株距0.5m、行距1.32m)为宜,成熟果数、单果重、单果种子数最多,种子产量最高可达到1 201.5kg.hm-2;"彩特美"细胞酶植物生长调节剂在籽用南瓜、籽用角瓜上应用可促进生长,显著提高坐果率和产量,增产幅度达10%以上,可大面积应用。

Effects of Density,Varieties and Growth Regulator on Yield and Quality of Seeds-Used Pumpkin

in order to develop pumpkin seeds planting at large area,make best potential of seed’s yield of pumpkin,improve the unit area yield as well as quality and increase farmers’ income,the effect of different densities,varieties and growth regulator on yield and quality of seeds-used pumpkin were explored.The results showed that there was no difference on the growth period between the experimental verities,Yinhui No.2 was the first suitable variety because of its weak branchiness and good yield characteristics;The optimal density was 15 000 plant·hm-2,for its yield could reach 1 201.5 kg·hm-2;The growth regulator of ’Caitemer’ could improve the growth and fruit setting percentage,as well as increase yield by more than 10%,it could be used at large area.
