The latest course of grafting techniques and methods of cucumber

Cucumber grafting is the key to high yield. Grafting refers to grafting branches or buds of one plant onto other plants to make them a complete plant. At present, grafting is widely used in cucumber production. It can improve the stress resistance and disease resistance of cucumber, and improve the yield and efficiency. Let's take a look at the detailed introduction together with Xiaobian.

1. Rootstock and scion selection

Suitable for cucumber rootstocks larger, such as common pumpkin, loofah, gourd, gourd, etc., and according to experiments, that China's black-seeded pumpkin and white-seeded pumpkin are more suitable, they can withstand low temperature, and cucumber affinity is good, early after grafting, can be listed ahead of time, seize the market, and cucumber has no adverse effects. The scion should be selected mainly from varieties suitable for greenhouse cultivation, and should be selected from excellent varieties with low temperature tolerance, early maturity and strong disease resistance.

2. Contact method

The grafting method is a commonly used grafting method in rural areas. It is simple to learn and has a very high survival rate. When applied, cucumber should be sown 3-5 days earlier than grafted rootstock, and rootstock and scion with similar growth height should be selected for grafting. Grafting time is when pumpkin grows two cotyledons and cucumber grows the first true leaf. Take out the two kinds of seedlings, remove the true leaves of pumpkin seedlings, and cut obliquely 1-1.5 cm below the pumpkin seed leaves with a knife, the depth is half of the stem diameter. Then in cucumber cotyledons under 1.5-2 cm plant oblique hanging, depth of stem diameter three-fifths, two cut embedded, cucumber leaves to press on the pumpkin leaves, fixed well can.

3. Oblique insertion method

Oblique grafting method requires larger trees and smaller cuttings, so it should be sown first rootstock pumpkin, then scion cucumber, rootstock grafting time is suitable when seedlings grow to one leaf and one heart, true leaves spread 3- 5 cm, and scion should wait until cucumber seedlings cotyledons spread, cotyledons color becomes dark green, true leaves do not grow out. During grafting, the true leaves, heart leaves and growth nodes of the rootstock are removed, and then the stem base is obliquely inserted within 1 cm with a bamboo stick of scion thickness, so as to destroy the epidermis of the hypocotyl. The bamboo stick is not pulled out temporarily. The selected scion and bamboo stick have the same thickness, balance the knife at the position of cotyledon 1 cm, obliquely cut into two thirds of the hypocotyl, cut the scion from the opposite side, cut the scion, pull out the bamboo stick at this time, and insert the scion obliquely into the hole.

The above is the introduction of cucumber grafting technology, I hope to help you, want to know more about the relevant knowledge, please pay attention to us.
