The grafting of peach root branches can reduce the breeding anvil link, and the direct colonization of grafted seedlings grows faster than that of the nursery. The results can be obtained in the second year, and the high yield can be produced in the third year. The technical points are as follows:
1. Anvil root collection. Peach seedlings or Taoyuan winter and spring soil, collect peach seedlings or peach roots within 5 years of life, select the fibrous roots, no pests, no damage, 0.5 ~ 1.5cm in diameter roots for the anvil. The roots of the anvil are bundled into small ones and placed in the indoor wet sand pit for burying and standby. The humidity of the sand in the pit is suitable for loosening by hand and loosening.
2. Scion collection. Select high-quality, high-yield, and high-resistance varieties as the mother tree for cuttings, and cut the full-length one-year-old leafy shoots for scion in the outer part of the crown, usually with the graft. In winter, scion collection is used in conjunction with pruning. The scion is bundled into different varieties and buried in a wet sand pit for storage. The humidity of the sand is the same as that of the storage anvil.
3. Grafting method. Grafting should be carried out in indoor or outdoor leeches during the spring peach trees. Commonly used cutting method and splicing method, scion length 8 ~ 12cm, the upper end retains 2 to 3 full leaf buds; anvil root length 15cm, retain fibrous roots, with anvil root (big head) smooth and straight side to make a bit, align Form a layer and then use a plastic film strap to secure the port.
4. Colonization. Grafting seedlings need to dig a hole before planting, with a hole width of 70cm and a depth of 60cm, backfill with fine soil, and apply the base fertilizer layer by layer. The backfill soil is 20cm above the ground. The upper part of grafted seedlings was covered with plastic bags. When planting, planting acupuncture points to dig a small hole, put the anvil root in the hole, the fine soil culture around the roots, cover soil to 3cm below the interface, step on the soil, cover loose soil made of bread-shaped. After planting, the cavity surface was covered with a plastic film that was larger than the hole surface, the middle shear hole exposed the scion, and the soil was compacted around the middle of the film and in the middle. In case of dry soil, it should be irrigated when planting.
5. Post-plant management. When the soil is dry, or when the scion tip is full of bagging, cut the upper end of the bagging to expose the new tip, remove the bagging after a few days, and choose to leave a robust new tip as the main trunk, erase the rest, and release the tie. band. Afterwards, according to the growth condition of the grafted seedlings, it should be dried in due course and cultivated into a canopy.
