嫁接技术在黄瓜栽培中的应用研究

Study of the Application of Grafting in Cucumber Growing

嫁接是日光温室黄瓜高产栽培中的一项重要措施。嫁接苗较自根苗生长势强,株高、叶大、雌花率高、成瓜率高、化瓜率低、始收期提前、拉蔓期推迟、采果期延长、单瓜重增加,前期产量、总产量均有较大幅度提高,苗期死苗率及枯萎病、霜霉病、白粉病的发病率均降低。

Grafting is an important technique ted seedlings adopted in growing high - yield cucumber in sunlit greenhouses. Grafare growing better than self- root seedlings, with higher plants, larger leaves, higher female flower ratio, higher fruit yield ratio, lower fruit abortion ratio, earlier harvest, later ending time, longer harvest period, and larger single fruit weight. Grafting can greatly increase the early yield and total yield, and at the same time decrease the dying seedling ratio as well as blight, downy mildew and powdery mildew ratio.
