日本蔬菜栽培的特点之一是多采用嫁接,尤其在果菜类上较盛行。其目的主要是抗病、高产。但存在的问题是品质劣化。品质易下降的有西瓜、甜瓜、西红柿。这些果菜通过嫁接后果形乱,糖分下降,这都是优势砧木即西瓜、甜瓜的南瓜砧木、西红柿的杂交种(一方亲本是野生种)砧木根的活性,养分吸收能力强的原因。黄瓜、茄子嫁接一般不影响品质,相反地由于砧木的选择株势变强,不仅产量提高,且多使品质变好。选择砧木首先要考虑当地发生的土壤病害种
One of the characteristics of Japanese vegetable cultivation is to use more grafting, especially in fruits and vegetables more prevalent. Its main purpose is disease resistance, high yield. But the problem is the quality of the deterioration. Easy to drop the quality of watermelon, melon, tomatoes. These fruits and vegetables through the grafting after the fruit chaos, sugar decreased, which are dominant rootstock that watermelon, melon pumpkin rootstocks, tomato hybrids (one parent is the wild species) rootstock root activity, nutrient absorption reasons. Cucumber, eggplant grafting generally does not affect the quality, on the contrary due to the stock selection of stockstock becomes stronger, not only to increase production, and more to make better quality. Rootstock selection must first consider the local occurrence of soil diseases
