Problems solved by technology

The production and planting of pomelo mainly adopt high-quality grafted seedlings, and the grafting methods of pomelo grafted seedlings mainly adopt the cutting method and abdominal grafting method; the cutting method has the disadvantages of long rootstock cultivation time, low utilization rate of ear buds, large labor and tidy grafting. Poor degree of grafting, only suitable for winter grafting and other problems; abdominal grafting method has the disadvantages of timely erasing rootstock buds 2 to 3 times, cutting stock 1 to 2 times, slow growth, poor uniformity, and only suitable for spring and autumn grafting.

Embodiment 1

[0018] Embodiment one: a kind of method that improves pomelo class grafting seedling raising efficiency

[0019] The present embodiment takes Guanxi honey pomelo as an example, and the method for improving Guanxi honey pomelo grafting seedling efficiency is as follows:

[0020] 1, select rootstock seedling: be rootstock seedling with sour pomelo seedling;

[0021] 2. Select the grafting site and grafting method:

[0022] (1) Select the grafting site: take advantage of the advantages of the top of the plant growth, the strong healing ability of the pomelo branch diameter, and the rapid germination of the ear buds for grafting. The gradient test is set in the interval from 0 to 5.0 cm from the grafting cut to the top. Table 1 shows the comparative test results of different grafting sites.

Embodiment 2

[0028] Embodiment two: the method for improving the efficiency of red-fleshed honey pomelo grafting seedling raising

[0029] In October, select pomelo seedlings with a diameter of not less than 0.5 cm at a distance of 8 to 10 cm from the ground as rootstock seedlings, and cut the stock at 8 to 12 cm from the ground one day before grafting or on the day of grafting. 0.5-1.5cm away from the top notch, and cut downwards to a length of 1.2-1.5cm. The depth should slightly damage the xylem (see Bailiuqing). Cut off 1 / 2 of the peeled cortex. The single ear buds are put into the grafting interface, and the single ear buds of the red-fleshed honey pomelo are selected from healthy spring shoots that have been bred and bred in the same year; the cut surface of the ear buds is aligned with the cambium on at least one side of the cut edge of the stock, and is wound and tied tightly with a special grafting plastic film , Grafting cuts, ear buds, and cuts at the top of the rootstock must b...

Abstract

The invention relates to a method for improving the seedling cultivating efficiency of pomelo grafting. A top side end bud grafting method is adopted. Top side end single-ear bud grafting is carried out on the optimal portion of a stock, the characteristic of apical dominance of plant growth can be brought into full play, growth of grafted ear buds is promoted, and the grafting success rate and the uniformity are improved; meanwhile, two to three times of stock bud picking after grafting can be reduced, labor for cutting the stock again after grafting survival can be saved, the seedling cultivating cost can be saved, the seedling cultivation rate of high-quality pomelo seedlings is increased, pomelo grafting can be carried out on anniversary, and the seedling cultivating efficiency of pomelo grafting can be multiplied. The method is easy to operate, easy to learn and popularize, stable in effect, free from toxic and side effect and pollution, small in investment, high in benefit, and wide in application prospect, and is a new effective way for farmers to become rich.

Description

technical field [0001] The invention relates to a method for improving the efficiency of fruit tree grafting and seedling cultivation, in particular to a method for improving the efficiency of grapefruit grafting and seedling cultivation, belonging to the technical field of fruit tree cultivation. Background technique [0002] In recent years, China's pomelo planting industry has developed rapidly, with pomelo planting area and output ranking first in the world, and the demand for high-grade grafted seedlings of fine pomelo varieties is strong. The production and planting of pomelo mainly adopt high-quality grafted seedlings, and the grafting methods of pomelo grafted seedlings mainly adopt the cutting method and abdominal grafting method; the cutting method has the disadvantages of long rootstock cultivation time, low utilization rate of ear buds, large labor and tidy grafting. Poor degree, only suitable for grafting in winter and other problems; abdominal grafting method h...
