不同砧木嫁接对西瓜生长发育及产量的影响

Effects of Different Rootstock on the Yield and Development of Citrullus lanatus var. lanatus

研究了豫园砧木王(Citrullus lanatus var.citroides cv.Yuyuanzhenmu)、超丰F1(Lagenaria sicer-aria cv.Chaofeng F1)、新土佐(Cucurbita maxima×C.moschata,Sintozwa)3个西瓜砧木嫁接对西瓜(Cit-rullus lanatus var.lanatus)生长发育、根系的分布及产量的影响。结果表明,3种不同砧木西瓜嫁接苗与自根苗相比,根系发达,茎叶生长旺盛,且有增产作用。其中豫园砧木王和新土佐砧木的嫁接效果最好,其能明显增强嫁接苗的长势,可分别使西瓜增产21.4%和25.0%。因此,建议选择豫园砧木王和新土佐嫁接西瓜为好,以达到丰产的目的。

Effects of Citrullus lanatus var.citroides cv.Yuyuanzhenmu,Lagenaria siceraria cv.Chaofeng F1 and Sintozwa（Cucurbita maxima ×C.moschata） on the development,distruction of the roots and the yield of C.lanatus var.lanatus were studied.The results showed that,compared with non-grafted seedling,the roots and shoots of the grafted seedlings with three rootstocks developed faster,and the yield increased.Of the three rootstocks,the grafting effect of C.lanatus var.citroides Yuyuanzhenmu and Sintozwa（Cucurbita maxima ×C.moschata） was better.The growth vigor and yields of grafted seedlings increased by 21.4% and 25.0% respectively.So,to grain high production,C.lanatus var.citroides Yuyuanzhenmu and Sintozwa（Cucurbita maxima ×C.moschata） were recommended to be used as rootstocks of C.lanatus var.lanatus.
