First, the use of fast-growing rootstock jellyfish, West House jellyfish compared cold, drought, waterlogging resistance, salt and alkali resistance, and apple graft affinity, root development, rapid seedling growth, then can reach the grafting of the summer rough. Fourth, early picking up the heart, early grafting When the anvil seedlings grow to 30 centimeters or so when the heart can be tossed, to promote its bold growth; base diameter of 0.5 to 0.6 centimeters can be grafted and completed before the end of June. Only in this way, grafted seedlings have a longer growth time. Fifth, take high budding measures Do not immediately cut and paste after budding, but in the bud 1 or 2 cm above the rootstock will not break broken, prompt budding germination, bud to be long to 5 to 6 true leaves Then cut the anvil again. In addition, to improve the grafting site, leave 5 to 7 functional leaves under the bud to provide the nutrients needed for budding, and then cut the anvil after budding. 6. Strengthen fertilizer and water management Select fertile land plots as nurseries and increase the amount of base fertilizer to be applied. Before the seedlings are grafted, 10 to 15 kg of topdressing urea can be combined with watering; after grafting, 8 to 10 kg of urea per acre is applied; in early August and early September, each time the compound fertilizer is applied to each acre of 8 to 10 kg, foliar spraying fertilizer once every 15 days, spraying 300 times urea in the early stage and spraying 300 times potassium dihydrogen phosphate in the later stage.

Second, grasp the appropriate seedling time is appropriate for autumn sowing, filming immediately after sowing, spring sowing will be sowed earlier. In this way, early emergence and early growth can be achieved, and the number of days of early growth can be prolonged to reach the goal of early grafting and seedling growth in the same year.
Third, take protective measures in the early spring should do a good job of cold, moisturizing and other measures. Common protective measures include cold wind barriers, impotence, hotbeds, and plastic film coverage. The mulch film and shed film cover seedbeds for seedlings, and then transplanted to the open field grafting garden. This method of sowing can be advanced, but must wait until the late frost can be transplanted, otherwise the nursery should also take protective measures. In order to solve this contradiction, double membranes are often used to cover live seedlings in production, but the cost is high.
