蔓割病是西瓜最危險的病害,由土壤传染,病原菌在土壤中能生活10年以上,致瓜田不得不长期輪作。嫁接法不但能防止蔓割病縮短輪作年限,且因砧木强健可早播、早定植,吸肥力强,生长势旺盛,早收丰碩果实。兹将具体操作方法簡述于次。 (1)砧木歧阜农試曾用扁蒲,南瓜、胡瓜、冬瓜等做过試验,所得結果,以扁蒲砧最佳。扁蒲一般发芽不良,处理时先于种胚部稍稍凸
Manchurian disease is the most dangerous watermelon disease, from soil infection, the pathogen in the soil can live more than 10 years, causing melon field had long-term rotation. Grafting method can not only prevent the crop rotation shortened crop rotation, and because of strong rootstock early sowing, early colonization, strong absorption of fertility, strong growth potential, early harvest of rich fruit. The specific method of operation will be described in the second. (1) Rootstock Gifu farming test had used flat Pu, pumpkin, cucumber, melon and other tests done, the results to the best Bupleurum. Bupleurum general malformations, dealing with the first embryo slightly convex
