Embodiment 1

[0021] 1. Slotting bed preparation

[0022] Go to the red bayberry planting area to dig mountain loess, its pH value is between 5.0 and 6.5, which belongs to sandy soil, transport it to the slotting bed to be flat, with a thickness of 30 to 40 cm, and then make ridges in the east-west direction, with an interval of 10 cm between ridges and a height of 5 cm. Width 5cm, spray 800 times of 50% carbendazim or 40% thiophanate-methyl 800 times solution at the same time to carry out soil sterilization.

[0023] 2. Treatment of cuttings

[0024] At the end of September and mid-October every year, select a strong mother tree that has borne fruit for 15 years to collect lignified branches of the year. The thickness of the base of the branches is more than 0.3cm and less than 0.5cm. The base of the cuttings is cut at an angle of 45°, the upper part of the cuttings is flat, and 2 to 3 leaves are left on the upper part of the cuttings. Every 20 cuttings are tied into a bundle, and the ba...

Embodiment 2

[0033] The red bayberry propagation method comprises the steps:

[0034] 1. Slotting bed preparation

[0035] In summer, go to the red bayberry planting area to dig mountain loess and it is raw soil. Its pH value is about 5.5. Transport it to the slotting bed and add 5% peat soil to make it flat with a thickness of 30-40cm. It is 4cm high and 6cm wide, and covered with black plastic film for high temperature sterilization of soil.

[0036] 2. Treatment of cuttings

[0037] In mid-September of that year, select a strong mother tree that has borne fruit for 15 years to collect lignified branches of that year. The thickness of the cut is more than 0.3cm and less than 0.5cm, and cut into cuttings about 15cm long. The base of the cuttings is cut at 45° Oblique cuts, the upper part of the cuttings are flat, and 2 leaves are left on the upper part of the cuttings. After binding every 20-30 cuttings, soak the base of the cuttings in 0.15% silver nitrate solution for 12 hours in the...

Abstract

The invention provides a method for cutting and breeding myrica rubra seedlings. The method comprises the following steps: (1) preparation of slotting machine: the mountain loess is selected as matrix, and the loess is sand soil, the pH value of the matrix is ranged from 5.0 to 6.5; after being flattened, the slotting machine is ridged, fungicide is applied to a ridge to disinfect; (2) cutting treatment: myrica rubra branches with a certain thickness and length are selected, branch bases are sheared to be an oblique incision, the upper part of the branch is reserved with 2-3 leaves as cutting slips for cutting; base parts of the cutting slips are immersed in silver nitrate solution in the dark for 12 hours or in the clean water for 24 hours; (3) cutting method: the immersed cutting slips are inserted to a matrix of the ridge watered thoroughly and covered with a black mulching film; the inserting part of the cutting slips is one third of the cutting slips; (4) after-cutting treatment: the cutting slips are inserted to the ridge and then immediately watered thoroughly and covered with a sunshield screen; then the cutting slips are timely poured with the right amount of water and nutrient solution. With the adoption of the method, the survival rate of cutting and breeding myrica rubra seedlings is effectively improved.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to the technology of bayberry seedling propagation. Background technique [0002] Red bayberry is a unique evergreen fruit tree in southern my country. It is rich in nutrition and is deeply loved by consumers. It has become one of the high-effect trees vigorously developed in the hilly and mountainous areas of southern my country. The cost is high and the cycle is long, which has seriously affected the popularization and application of new varieties of fruit trees, and there is an urgent need for a low-cost and easy propagation method to propagate red bayberry seedlings. [0003] Cutting propagation is an important method of asexual propagation of fruit trees, but bayberry cuttings contain relatively high tannins, and cuttings are not easy to take root, resulting in low reproductive survival rate. Therefore, how to improve the survival rate of red bayberry cutting pro...
