近年来,上海郊区冬瓜枯萎病很为严重,造成死苗、死藤,严重田块有种无收,使冬瓜生产受到很大的影响,为此我们开展了冬瓜嫁接栽培技术的研究。试验初步表明,嫁接的冬瓜对防止枯萎病有较好的效果,并能增强生长势,提高产量。现将冬瓜的嫁接技术小结如下。(一)砧木的选择冬瓜枯萎病菌(Fusarium oxysporum)在土壤中能存活多年,是以土壤带菌为主而引起的病害,选择砧木必须抗枯萎病,并与冬瓜有较好的亲合力,而且不影响产量、品质。供试的砧木,普通南瓜类型有本地猪头南瓜、黄狼南瓜、日本的白菊座南瓜;笋瓜类型有南京黄皮笋瓜、金山笋瓜;西葫芦类 In recent years, the suburbs of Shanghai melon wilt disease is very serious, resulting in dead seedlings, dead rattan, a serious crop of crop failure, so that the production of melon was greatly affected, for which we have carried out the melon grafting cultivation techniques. Preliminary tests showed that the grafted melon to prevent blight have a good effect, and can enhance the growth potential, increase production. Now melon grafting technology is summarized as follows. (A) the choice of rootstock Fusarium oxysporum Fusarium oxysporum in the soil can survive for many years, is mainly caused by soil-borne diseases, the choice of rootstocks must Fusarium Wilt, and melon has better affinity, and not Affect the yield, quality. For the rootstock test, the common pumpkin types are local pig head pumpkin, yellow wolf pumpkin, Japanese white chrysanthemum pumpkin; winter squash types are Nanjing Huangpi winter squash, Jinshan winter squash; zucchini
