以西瓜品种淮蜜2号为接穗,强根为砧木,以普通贴接、插接法为对照,研究无萌蘖嫁接方法对嫁接工效、嫁接苗成活率、成苗率、萌蘖率、幼苗株高、接穗干质量、叶绿素含量、第1雌花节位、果实中心糖含量、皮厚及单果质量的影响。结果发现,与贴接、顶插接常用嫁接方法相比,无萌蘖贴接、蘖插接法的嫁接苗成活率、成苗率、幼苗株高,但第1雌花节位、平均单果质量、果实中心糖含量、皮厚及产量等指标无显著差异,嫁接工效、接穗干质量、幼苗真叶叶绿素含量存在极显著差异。但采用该技术嫁接的西瓜苗产生的萌蘖率均为0,极显著低于常用嫁接法,因此该方法可在生产中推广应用。无萌蘖嫁接幼苗生长量、真叶叶绿素含量明显低于常用的贴接和插接,但定植后,第1雌花开放时期与常用嫁接方法无明显差异,幼苗这一缺点可采用延长苗龄的方法来克服。
With watermelon variety Huai honey 2 as the scion and strong root as the rootstock, the common method of splicing and plugging was used to study the effects of grafting efficiency, the survival rate of grafted seedlings, the rate of seedling emergence, the seedling rate Plant height, dry scion quality, chlorophyll content, the first female flower node, sugar content in the center of the fruit, skin thickness and fruit quality. The results showed that compared with the conventional grafting method, the survival rate of grafted seedlings without sprout, tillering and plugging method, the seedling emergence rate and seedling height of the grafted seedlings were the highest, but the first female flower node, the average fruit weight There was no significant difference in the sugar content, thickness and yield between the fruit center, the grafting efficiency, the quality of scion and the leaf chlorophyll content of seedlings. However, the watermelon seedlings grafted by this technique all had 0, very significantly lower than the common grafting method, so the method can be applied in production. No sprout grafted seedling growth, true leaf chlorophyll content was significantly lower than the commonly used paste and plug, but the first female flower opening after planting and grafting methods no significant difference, the shortcomings of seedling can be used to extend the seedling age Method to overcome.
