不同砧木嫁接对甜瓜抗病性及生长发育的影响

Effecct of Different Stock Varieties on Disease Resistance and Growth of Melon

为促进甜瓜产业的发展,增加瓜农收入,选用6种常用嫁接砧木作为试验材料,以薄皮甜瓜金妃作为接穗,研究不同砧木嫁接对甜瓜抗病性及生长发育的影响。结果表明:各砧木均能显著增强枯萎病防治效果,并具有显著的增产作用。其中尤以京欣砧3号表现出色,其枯萎病和白粉病发病率相比自根嫁接植株分别低了38.1和8.2个百分点,产量提高了17.89%,且亲和性及果实品质等指标均接近于自根嫁接植株,是黑龙江省金妃甜瓜保护地栽培的理想砧木。

In order to promote the development of melon industry and increase the income for farmers, taking six common grafting rootstocks as experimental materials and thin-skinned melon Jinfei as grafting, the effects of difference rootstock on disease resistance and development of melon were studied. The results indicated that all kinds of rootstocks could increase the resistance to Fusarium wilt and its yield significantly. Comprehensive a- nalysis of six stock varieties characters showed that Jingxinzhen 3 was suited for stock on the Jinfei melon,the yield of grating increased by 17.89% ,the disease rate of Fusarium wilt and powdery mildew were 38.1 and 8.2 which was lower than control and there were no significant differences in affinity and quality between grafting and own-root plants, so Jingxinzhen 3 as rootstock of Jinfei was suitable and could be popularized in Hei- longjiang province.
