Công nghệ canh tác
1. Seed reproduction: Take plants with strong tree vigor and many fruits, harvest them after the fruits are ripe, dry them in the shade, and avoid sun exposure, otherwise the seeds will easily lose their germination ability. In spring sowing, in late March to early April, use the strip cutting method, dig a furrow with a row spacing of 15-20cm, 3-5cm deep, sow the seeds evenly, cover them with a thin layer of fine soil, cover them with a layer of grass, and water them to keep them moist. Now it is rarely used in production because of its slow reproduction speed.
2. Division reproduction: In late December, you can dig up the topsoil of the lateral roots at a distance of 0.6m from the mother plant to expose the thicker lateral roots, cut a wound every 7cm or so, and then cover them with soil and apply manure. Seedlings grow out of the wound in spring. When the seedlings grow up, they can be separated from the mother plant.
3. Cutting propagation: Branch cutting method, in November-December or January-February before the plant sprouts, cut 1-2 year old strong branches as cuttings, 20-25cm long, with 3-4 buds, cut both ends into bevels, and cut them into the seedbed, 5-10cm above the ground, cover with a layer of grass, pay attention to watering and shade. Rooting takes about 1-2 months after cutting. Transplant the seedlings at a height of 30cm in the second year. Root cutting method, select trees 4-6 years old, around early February, select thicker lateral roots, cut into 15-18cm small sections as cuttings, dig holes according to the row spacing of 15cm×15cm, insert a section obliquely in each hole, cover with soil, and water. Seedlings can be transplanted in the second year of seedling cultivation. The transplanting time is March-April or November-December. Dig holes with a row spacing of (1.5-2) m×(1.5-2) m, with a hole diameter of 60 cm and a depth of 45 cm. Apply decomposed manure, dip the roots of the seedlings in yellow mud and plant them, cover the soil, compact and water them.
Disease and insect control
1. Sooty mold, kill the infectious source in May-June, spray 1:1:200 times Bordeaux liquid.
2. Rust, spray 0.2-0.3 degrees of Baume lime sulfur or 100 times of 25% triadimefon when the disease occurs in mid-May. There are also resin diseases and other harms.
3. Brown longhorn beetle, harms from July to October, the larvae bore into the trunk and eat the wood, which can be caught manually.
4. Orange swallowtail butterfly, in March, the larvae bite buds, young leaves or bite into notches and holes, and can be sprayed with 300 times Bt emulsion. Aphids, red wax scale insects and other pests are also present.
