疫病对我市西瓜生产威胁很大,在结瓜初期死苗达35％,严重时无收。 1983年采用嫁接换根连续三年重复试种,发现连作土内未发生疫病死苗,而且植株生长茂盛,蔓叶粗壮肥大,单瓜重量提高50％以上。比在同样栽培条件的未经嫁接、不连作的同品种西瓜产量提高107.9％。经品质鉴定,同未嫁接的西瓜风味基本一致。西瓜嫁接换根,砧木具有强大的根群系统,有抗高温、抗病的生理特点并且亲和力强。试种结果,瓠瓜砧木嫁接的西瓜苗成活
The disease poses a great threat to the production of watermelon in our city, with 35% dead seedlings in the early stage of fruiting and no income in severe cases. In 1983, grafting for roots for three consecutive years repeated trial and found that even in the earth did not occur disease dead seedlings, and plant growth, lush, thick vine, single melon weight increased by 50%. Compared with the same cultivation conditions, the yield of watermelon of the same breed without the grafting increased 107.9%. The quality appraisal, with the grafted watermelon flavor basically the same. Watermelon grafting roots, rootstocks have a strong root system, with high temperature, disease resistance and physiological characteristics and affinity. Test results, the melon rootstock grafted watermelon seedlings survive
