Embodiment 1
[0025] A method for grafting guava, comprising the following steps:
[0026] A. Selection of scion and rootstock: Scion is selected from high-quality guava cut strips, with a thickness of 3-5mm; stock is selected from guava seedlings that are more than 0.5 years old, and the average cut height of each seedling is above 12cm, and the cut thickness is 15-5 20mm;
[0027] B. Grafting preparation: the grafting time is March 10, 2013, on a cloudy day, cut the high-quality guava seedlings into 1.5cm long scions, and keep 2 full bud eyes on the scions; remove the leaves;
[0028] C, grafting: cut off the scion epidermis on the flat side, the cut surface is 1.0cm long, 0.3cm wide, and the depth just reaches the xylem; cut the scion to 2cm long; select the position where the rootstockdiameter is slightly larger than the scion to cut off the rootstock, and then from the section The epidermis towards the south is peeled off, the depth just reaches the xylem, and the width is consistent...

Abstract
The invention provides a psidium guajave tree grafting method. The psidium guajave tree grafting method comprises following steps of scion and rootstock selection; grafting preparation; grafting; and management after grafting. A seedlingpsidium guajave sapling has an arbor woody root, the root system of the sapling is developed, and the grafting survival rate is guaranteed; the seedling psidium guajave sapling and a high-quality psidium guajave sapling belong to the same family and the scion has strong affinity with the stock, so that the success rate of grafting is greatly increased and the growing speed of the grafted sapling after grafting is also increased; the psidium guajave seedling sapling has strong drought resistance, and under the drought condition, the grafting survival rate can be ensured, so that the grafted psidium guajave sapling can blossom and bear fruits within two years. The method of grafting the seedling psidium guajave sapling with the high-quality psidium guajave sapling is simple and convenient and has the high survival rate; the coverage rate of the high-quality psidium guajave varieties is increased; and the fact that the psidium guajave tree blossoms and bears fruits in advance is achieved.
Description
[0001] 【Technical field】 [0002] The invention relates to the field of plant grafting, in particular to a guava grafting method. [0003] 【Background technique】 [0004] Guava, which belongs to the family Myrtaceae, is an evergreen small tree or shrub, commonly known as guava seeds and that pull.
