[0054] (2) Remove the plastic film around the grafted bud 30 days after grafting, and timely remove the buds sprouting on the straight main stem of Huizhi, only keep the buds and branches of multiple flower Huizhi;

[0055] (3) In the autumn of the grafting year, you can get the water stacking pot type tree shape, because the annual branches of multiple flower Huizhi have poor cold resistance, directly move the plant to the plastic greenhouse for wintering after the fall of leaves.

[0056] Example 3

[0057] A method for making a Huizhi water stacking pot type, the specific technical solutions are as follows:

[0058] 1. Rootstock cultivation

[0059] (1) Container seedling of Hujuzi was carried out by using softwood cutting method. The cuttings were taken from adult Hujuzi without disease and insect pests. The branches on the upper part of the crown with a length of 8-10 cm were selected in June and July for cutting with a cutting depth of 1.5-2 cm. The cutting substrate was a mixture of equal volume of grass charcoal and vermiculite. The cultivation container was a 1-gallon pot, and the conventional management was carried out.

[0060] (2) After leaf fall in the first autumn, 2 / 3 of the branches above ground were cut off, combined with pot changing, and 1.5-2 g of compound fertilizer with a ratio of N:P:K of 20:20:20 was applied as basal fertilizer at the same time;

[0061] (3) After leaf fall in the second autumn, the base sprouts were cut off, and only three main branches were retained. The length of 1 / 3 of the branches of main branch 1 was cut off, the length of 1 / 2 of the branches of main branch 2 was cut off, and the length of 2 / 3 of the branches of main branch 3 was cut off.

[0062] (4) After leaf fall in the third autumn, the straight branches of each main branch, the branches near the base of each main stem, and the top shoots were cut off, and only the curved downward branches were retained.

[0063] 2. Grafting

[0064] (1) In the middle and late April, the buds of Hujuzi that were about to sprout in spring were selected for grafting.

[0065] (2) The rootstocks of four-year-old Hujuzi within a range of 70-80 cm from the ground were selected and grafted from bottom to top in a spiral pattern. The interval between each grafting point was 4.8-5.2 cm, and a total of 6 bud bodies were grafted.

[0066] (3) A 1-1.5 cm incision was made along the phloem at the rootstock cut surface to obtain the rootstock incision.

[0067] (4) A horizontal cut was first made 0.5 cm above the leaf bud with a width of 0.8-1 cm, and then a horizontal cut was made 1 cm below the leaf bud. The cutting was performed from the upper cut position along the xylem from top to bottom with a lower part of 0.3-0.5 cm to obtain the shield-shaped scion.

[0068] (5) The shield-shaped scion was inserted into the interface, and the scion was completely wrapped with plastic film.

[0069] 3. Post-grafting management

[0070] (1) After grafting, the whole plant was placed in a plastic greenhouse and watered thoroughly.

[0071] (2) After 30 days, the plastic film around the grafted bud is removed, and the buds growing on the straight trunk of Hu zhi Zi are removed in time, only the buds and branches of Hu zhi Zi are reserved;

[0072] (3) The tree shape of the water pot type can be obtained in the autumn of the grafting year. Since the annual branches of Hu zhi Zi have poor cold resistance, the grafted Hu zhi Zi part needs to be wrapped for protection in time in the winter of the second year, and the protection is removed in the early spring of the second year.

[0073] The flowering periods of Hu zhi Zi, Hu zhi Zi and the water pot type are counted, as shown in Table 1

[0074] Table 1 Flowering period survey statistics

[0075]

[0076] As shown in Table 1, the flowering periods of Hu zhi Zi and Hu zhi Zi are slightly overlapped, and the flowering time of the water pot type plant is about 20 days and 60 days longer than that of Hu zhi Zi and Hu zhi Zi before grafting, respectively, which improves the flowering and viewing time.

[0077] The effect of the height of the grafting position from the ground on the survival rate is counted, as shown in Table 2.

[0078] Table 2 Effect of grafting height on water pot type tree

[0079]

[0080] Note: The length of the drooping branches of Hu zhi Zi can reach 1m, and the length of the drooping branches of Hu zhi Zi can reach 60cm. As shown in Table 2, it is not easy to form a beautiful tree shape if the distance from the ground is too close or too far, and grafting at a distance of 60-70cm from the ground is beneficial to the formation of the water pot type.

[0081] The effect of grafting method and grafting number on the water pot type tree is counted, as shown in Table 3.

[0082] Table 3 Effect of grafting method and grafting number on water pot type tree

[0083]

[0084] Note: The grafting position is 60-70cm from the ground, the grafting points of spiral grafting are spaced 4.8-5.2cm apart, and the grafting points of ring grafting are at the same height from the ground. As shown in Table 3, the grafting form of arranging the grafting buds on the trunk in a spiral shape has appropriate operation difficulty and easy to ensure the survival rate, and the grafting operation difficulty of arranging the grafting buds on the trunk in a ring shape is larger and the survival rate is lower. Too few or too many grafting buds will affect the overall viewing effect. Considering the grafting difficulty, viewing effect and survival rate, the number of grafting buds is 6, and the spiral grafting effect is the best.
