嫁接黄瓜具有抗病、丰产、耐低温的特性。实践证明,嫁接黄瓜不仅可以防治蔓割病、疫病、白粉病和沤根,而且还能促使黄瓜蔓在低温下伸长。在土传病害发生严重的地区,一般采用云南黑籽南瓜作砧木进行黄瓜嫁接栽培。近几年来,多采用黄瓜嫁接新技术——生长点直插法,方法简便,容易操作,工效高。但在生产实践中,由于生产者对生长点直播法的技术掌握不当,嫁接苗的成活率较低,在很大程度上影响了经济效益和社会效益。我们认为要提高嫁接苗成活率,必须抓好以下关键措施。
Grafted cucumber with disease resistance, high yield, low temperature characteristics. Practice has proved that grafted cucumbers can not only prevent and control the crop disease, blight, powdery mildew and prickly heat root, but also to promote cucumber creep at low temperatures. Severe soil-borne diseases occur in regions, the general use of Yunnan black seed pumpkin for rootstocks grafted cucumber cultivation. In recent years, the more use of cucumber grafting new technology - growing point interpolation method, the method is simple, easy to operate, high efficiency. However, in the practice of production, the survival rate of grafted seedlings is relatively low due to improper mastery of the producer’s direct-seeding method of growing point, which has greatly affected the economic and social benefits. We believe that to improve the survival rate of grafted seedlings, we must grasp the following key measures.
