Is it good to graft peach seedlings? How much is one? What are the techniques and methods?

Grafting is one of the methods of artificial propagation of plants, which is divided into branch grafting and bud grafting. So how about grafting peach seedlings? How much is one? What are the techniques and methods? Learned from the Shandong seedling base, the annual seedling price is about 1.6 yuan to 2 yuan, the more the quantity purchased, the price can be discounted.

Is it good to graft peach seedlings?

The main results are as follows: 1. Peach seedling grafting can not only achieve early fruit, enhance cold resistance, drought resistance, disease and pest resistance, but also economically utilize breeding materials and increase the number of seedlings.

2. Enhance the disease resistance of the plant.

3. Improve the ability of low temperature tolerance of plants.

4. It is beneficial to increase the output. The grafted seedlings have large thick stems and leaves, which can increase the yield by more than 40%.

5. The absorption range and capacity of root system were expanded. The root system of the grafted plant is twice as large as that of the self-rooted seedling, and it can absorb about 30% more nitrogen, potassium and more than 80% phosphorus than the self-rooted seedling in the same area, and can utilize the phosphorus in the deep layer of the soil.

What are the grafting techniques and methods of peach seedlings?

For the grafting of peach trees, the general fruit growers are used to grafting in spring and summer. In fact, it can also be grafted in autumn and winter, which can increase income. The methods are as follows:

1. Spring grafting: from the middle of February to the end of April, when the moisture of the rootstock has increased, it can be cut at 8-10 cm from the ground, and the variety scion can be grafted by cutting method. The survival rate of this method can reach more than 95%.

2. Summer grafting: from mid-May to early August, when the sap flows vigorously, peach trees sprout and spread leaves, and the new buds are not yet full, which is a good time for bud grafting. Dormant buds can be cut at the lower end of the growing branch or sprouting branch as a scion and budded on the sunny side of the rootstock about 10 cm from the ground. Two weeks later, the interface was obviously bloated, and some colloids were secreted, and the budding eyes were green, which indicated that they had been taken over. After 2-3 days, the anvil trunk was cut outward at 0.5 cm above the interface, and the cut was horseshoe-shaped to facilitate rapid wound healing. When the new tip grows to 6-8 cm, insert a support column on the edge of the rootstock to tie up the new tip and guide the growth in the upward direction. If it is found that no grafting survived, the second grafting can be carried out in time.

3. Autumn grafting: from late July to late September, when the bract leaves of the new buds have been formed, the scions with petioles can be cut for budding. Seven or eight days after grafting, if the retained petiole falls off at a touch, it proves that the grafting survived. After grafting, the rootstock can be cut off 0.5-1 cm above the interface before sprouting in the following spring. It can also be planted directly by semi-seedling method.

4. Grafting in winter: from the beginning of November to the end of January of the following year, the sap of rootstock has stopped flowing, and the method of rhizome grafting can be used at this time. That is, cut off the rootstock at the upper end of the rhizome, remove the soil around the rhizome for grafting, gently cover the moist fine soil around and let the scion show a little, and then cover with plastic film to protect soil moisture, heat preservation and drought prevention, in order to survive the winter. In the following spring, where the surviving scion will sprout quickly, the plastic film can be removed from mid-late March to early April. But to observe on time, the early germination of the scion will uncover the plastic film early, and the late germination will uncover the plastic film later. In short, it depends on the germination.
