Cucumber grafting method

Abstract

The invention discloses a cucumber grafting method which comprises the steps of growing seedlings of stock and scion seed respectively; when the hypocotyl of the stock out of earth is 5-6cm long and the cotyledon tends to get flat and the scion seedling cotyledon is flat, removing the growing point of the stock seedling from the cotyledon; vertically and transversely inserting a disinfected bamboo stick into the hypocotyl on the vertical side of the cotyledon 0.3cm below the base of the cotyledon of the stock seedling, and transversely cutting the part 1.5-2cm below the growing point of the scion seedling into a single bevel; pulling out the bamboo stick, quickly inserting the single-bevel hypocotyl obtained by cutting the scion seedling while keeping the stock and the scion in a vertical state to finish the grafting; transplanting the grafted seedling into a tunnel, and managing the temperature, humidity, illumination and ventilation; about 18 days later, performing planting. The method disclosed by the invention has the advantages of simplicity in operation and quick grafting; the probability of infection at the wound of the grafted seedling can be remarkably reduced, and the survival rate of the grafted seedling is greatly improved; the requirement for the seedling age of the stock and scion is relatively low, and the period for obtaining the grafted seedling is short.

Description

technical field [0001] The invention relates to a method for grafting melons, fruits and vegetables, in particular to a method for grafting cucumbers. Background technique [0002] Cucumber, also known as pickled cucumbers and green cucumbers, belongs to Cucurbitaceae and is widely distributed throughout China. Cucumber grafting technology is a major technical measure to overcome continuous cropping obstacles, improve plant stress resistance, prevent cucumber wilt and blight and other diseases, and obtain high yield in cucumber production and cultivation. [0003] my country's cucumber grafting technology began in the 1980s, mainly using the advantages of rootstocks with developed root systems, strong water and mineral absorption, disease resistance, salt resistance, drought resistance, low temperature or high temperature resistance, and high yield, good quality, and high quality. The scions of cucumber varieties are combined into new plants to achieve the purpose of high qu...

Problems solved by technology

[0005] Although the above three methods have been used so far, there are still many defects in grafting: 1. The grafting method needs to use fixing tools such as grafting clips or gauze, which is troublesome to operate; After survival, the roots need to be cut off. After transplantation, the scion may fail due to the growth of fibrous roots at the low grafting site; the wound is large and easy to be infected by the outside world; the rootstock and scion seedling age are required to be relatively high

2. The splicing method needs to use fixed tools such as grafting clips or gauze, which is troublesome to operate; during moisturizing treatment, the cotyledon water droplets gather and easily flow into the wound, resulting in slow or non-healing of the healing site; the wound is large and easy to be infected by the outside world

3. During the moisturizing treatment of the top grafting method, the cotyledon water droplets are easy to flow into the wound downstream, resulting in slow or non-healing of the healing site; at the same time, if the top grafting method is inserted too deep, the grafting needle will be inserted into the hollow medullary cavity of the rootstock, and the scion will There are fibrous roots growing in the medullary cavity, causing false living
