西瓜嫁接技术在日本早已普遍应用于生产,我国北京市、湖南省、大连市近几年也开始应用。1986年我所接受了中日合作设施园艺试验任务,与日方技术人员合作,进行了不同品种西瓜,不同砧木的试验。结果表明,嫁接西瓜比自根西瓜增产30—50％,早熟2—7天,而且嫁接后的西瓜苗,具有耐低温、耐涝、耐旱和较强的抗病能力。1987年在沈阳市于洪区高花乡进行试验,在重茬连作发病严重地块种植西瓜,自根苗由于蔓割病引起枯死株率达85％,而嫁接苗无一发生蔓割病。嫁接苗新结的西瓜,经多人品尝没有异味,通过糖度计测试、糖度亦不降低。一、砧木的选择
Watermelon grafting technology in Japan has long been widely used in production, China’s Beijing, Hunan, Dalian has also begun to apply in recent years. In 1986, I accepted the tasks of Sino-Japanese cooperation in horticultural experiment and cooperated with Japanese technicians to carry out experiments on different varieties of watermelon and different rootstocks. The results showed that the grafted watermelon yield 30-50% more than the root watermelon, early 2-7 days, and grafted watermelon seedlings, with low temperature, water logging, drought tolerance and strong resistance to disease. In 1987, Gaohuaxiang, Yuhong District, Shenyang City, experiment was carried out. Watermelon was planted in severely vegetated continuous cropping area. The rate of dead plant due to sprouting caused by root-cause seedling was 85%, but none of the grafted seedlings were suffering from the disease. Grafted watermelon knot new knot, taste no smell after many people, through the sugar meter test, sugar level is not reduced. First, the choice of rootstock
