黄瓜苗期嫁接是一项新技术,其好处是能提高黄瓜的抗病性,加强根系的吸收能力,从而达到丰产的目的。日本在黄瓜、西瓜、甜瓜、西红柿栽培中已普遍采用嫁接法。我国一些省市也已应用这一新技术,并取得了可喜的成果。黄瓜与南瓜嫁接的技术原理是:在幼苗期间通过嫁接使接穗黄瓜和砧木南瓜的胚轴部分的输导组织接通,形成层愈合,用南瓜的根系取代黄瓜的根系。由于南瓜对枯萎病有免疫性,加上根系发达,吸收面广,嫁接苗比不嫁接菌生长迅速,健壮,这对因重茬而发生的病害具有重大的意义。
Grafting of cucumber seedling is a new technology, the benefits of which can improve the disease resistance of cucumber and enhance the absorption capacity of the root system, so as to achieve the purpose of high yield. Japan in the cucumber, watermelon, melon, tomato cultivation has been widely used in grafting. Some provinces and cities in our country have also applied this new technology and have achieved encouraging results. Cucumber and pumpkin grafting technical principle is that during grafting by grafting so that the scion and rootstock squash pumpkin hypocotyl part of the conduction tissue connected to form a layer of healing, with the root system of cucumber to replace the root system. As the pumpkin is resistant to blight disease, coupled with developed root system, wide absorption, grafted seedlings than non-grafting bacteria grow rapidly and robustly, which is of great significance for the occurrence of disease due to continuous cropping.
