近年来,随着西瓜种植面积的增加,在西瓜集中产区造成轮作困难,枯萎病越来越严重。据调查,枯萎病一般发生使西瓜减产1/3或1/2,严重田块甚至绝收。为了防治西瓜枯萎病的发生,并进一步提高产量、改进品质,我们于1989年引进了西瓜嫁接新技术,并作了试验、示范,1992年推广嫁接西瓜面积达4000亩以上。现将西瓜嫁接试验、推广情况总结如下,以探讨其推广价值。
In recent years, with the increase of watermelon planting area, it is difficult to produce rotation in the concentrated watermelon producing area, and the wilt disease is more and more serious. According to the survey, Fusarium so that the general occurrence of watermelon cut 1/3 or 1/2, a serious field even adversary. In order to prevent the occurrence of watermelon wilt, and further improve the yield and improve quality, we introduced a new technology of watermelon grafting in 1989 and made experiments and demonstrations. In 1992, the area of grafted watermelon was more than 4,000 mu. Now watermelon grafting test, the promotion of the situation are summarized as follows, to explore its promotional value.
