西瓜嫁接栽培技术在国内外已推广应用。应用面积较大的是日本,占西瓜栽培面积的95%以上,其次是南朝鲜、菲律宾等国家。我省在六十年代初曾进行西瓜嫁接试验,以后江苏、浙江、湖南等省科研院校也曾开展过西瓜嫁接试验,但由于采用嫁接方法单一,未能在生产上大面积推广应用。自1986年中日合作建立大连、沈阳园艺试验场以来,开展了西瓜嫁接栽培技术,砧木选育,嫁接方法等方面试验,初步摸清了西瓜嫁接栽培方面的关键技术环节,取得了理想的效 Watermelon grafting cultivation techniques have been popularized at home and abroad. Larger area is Japan, accounting for more than 95% of watermelon cultivation area, followed by South Korea, the Philippines and other countries. In the early 1960s, our province had carried out watermelon grafting experiments. Later, scientific research institutions in Jiangsu, Zhejiang and Hunan provinces also carried out watermelon grafting experiments. However, due to the single grafting method, large-scale production and application were not promoted. Since 1986, Sino-Japanese cooperation in establishing Dalian, Shenyang Gardening Experimental Field since the start of the watermelon grafting cultivation techniques, stock selection, grafting methods and other aspects of testing, preliminary find out the key aspects of watermelon grafting cultivation aspects and achieved the desired effect
