Seedling
After grafting, seedlings should be planted on the seedbed prepared in time. It should be planted on a raised bed, equipped with enough base fertilizer, deep and fine tillage, and the bed surface should be leveled. Press 10cm × Dig planting ditches at an interval of 0cm. If the water is insufficient, water the bottom of the planting ditch. The planting ditch shall be dug vertically from one side to the bottom. Hold the bandage in your hand and place it vertically into the ditch from one side and the other. Seal the fine soil on the surface of scion buds to expose the buds slightly, and then compact the soil without hurting the bandage. After planting, an arched shed shall be built immediately. The vertical height between the center of the bow shed and the air should be 50 cm, and the surrounding area should also be compressed to prevent wind and ventilation. The temperature in the shed is maintained at 18-0 ° C. Usually, the check-in must be completed before the beginning of April.
Nursery management methods.
1. Adhere to the temperature and humidity in the plastic shed: when the temperature in the shed rises to 0 ° C, immediately open the plastic film on both sides of the shed, ventilate and cool down, and keep the relative humidity in the shed above 90%. Spray water every -5 days, and it is recommended to always adhere to spray.
2. Seedling refining: Seedling refining is the main measure to promote the growth and development of grafted seedlings and improve the quality of seedlings. Seedlings can heal within 10-15 days after grafting, and leaves can be released within 0 days. At the end of April, when the daily average temperature reaches above 15 ℃, the hardening of seedlings should be stopped. On a sunny day, at 1 p.m., all the films were uncovered, and then covered before sunset, gradually increasing the time for sunlight to reach the seedlings. After hardening for 5-7 days, the plastic film can be removed.
3. De germination: in order to speed up the healing of the grafted joint and improve the survival rate, the adventitious buds on the rootstock should be removed in time, and do not be in a hurry to cultivate the seedling buds, so as not to affect the healing, germination and growth of the grafted seedlings. Even if the scion cannot survive, it can only leave a bud to promote the growth of grafted seedlings.
4. Strengthen water and fertilizer management: after the seedlings are exposed, they should often loosen the soil and weed, and water them in time. From June to July, fertilize once every 10-15 days, and fertilize four times in the whole growth period. Spray intensively, apply 4-5 kg of urea per mu, and water immediately after application, without affecting the growth of seedlings. At the same time, pay attention to drainage in flood season.
