Method for grafting citrus seedlings by using citrange cutting stock

Abstract

The invention relates to a method for grafting citrus seedlings by using a citrange cutting stock. The method comprises the following steps of: sowing a citrange stock in February and March of the current year, grafting a citrus variety on the citrange stock in October of the current year, performing the first stock pruning in February of the next year, and grafting the citrus variety on a cut citrange stock cutting for plantation; and cutting the citrange stock cutting on a cutting seedbed, and performing stock pruning, sprout removal, bud picking and the like according to normal maintenancemanagement after the end of April. A proper citrus variety is grafted by the citrange stock in October, the upper part stock of the citrange is pruned in March of the next year, the citrus is graftedby the pruned stock, and the grafted stock is put on the seedbed or in a greenhouse for management to promote simultaneous stock rooting and grafting healing. By the method, a single citrange stock can exert the benefit of 3 to 4 citrange stocks, so that the cost of the citrange stock is reduced. Besides, a seedling cultivation period of the stock is shortened, and the benefit is improved.

Description

【Technical field】 [0001] The invention belongs to the technical field of plant cultivation. More specifically, the present invention relates to a method for grafting citrus seedlings with citrange cutting rootstocks. 【Background technique】 [0002] There are many ways to propagate citrus seedlings, such as seeding, layering, cutting and grafting. At present, the grafting method is still the best and common method. It is also a mature citrus seedling raising technology. [0003] The grafted seedlings of citrus are combined by scion and rootstock. The rootstock is the plant that bears the scion during grafting and propagation. It can be the whole fruit tree, or the root segment or branch segment of the tree body, which plays the role of fixing and supporting the scion, and forms the plant growth and fruit after healing with the scion. Commonly used rootstocks for grafting citrus are trifoliate orange, orange, sour orange, sweet orange, sour lemon, orange, pomelo, etc. [00...

AI Technical Summary

Problems solved by technology

This method can solve the purpose of cultivating seedlings by grafting citrus oranges, but it has the following disadvantages: 1, because most of the seeds of citranges are imported, and each seed is close to 0.8 yuan, so the cost is very high; It usually takes one year for grafting, so the cycle is longer; 3. Importing citrange seeds requires a cycle and time, so the flexibility is poor, and the quality of the seeds cannot be effectively guaranteed
