Is Sapium sebiferum evergreen or deciduous?

Chinese tallow is a deciduous tree plant of Euphorbiaceae and Sapium sebiferum. Generally fall leaves in winter, in spring and autumn will grow beautiful leaves, no less than maple leaves. At present, it is widely planted next to houses, villages, roads or parks.

What are the high yield cultivation techniques of Sapium sebiferum?

1. Harvest seeds

The tree with normal growth, straight trunk, no diseases and insect pests and high fruiting rate was selected as the mother plant. Then the seeds are collected around November every year. When about 75% of the fruits are cracked, it is the best time to collect seeds. If the seeds are harvested prematurely, the seeds will be eaten by birds if they are harvested too late. After harvesting seeds, keep healthy and full seeds, and then pick out impurities, dryness and other useless seeds. Store it in a dry place.

2. Sowing seeds at the right time

(1) treatment of seeds: put the seeds in a container, add washing powder in warm water of about 55 degrees, and soak for 1 day. Then when the wax softens, rub it to remove the wax, clean it, and then soak it in potassium permanganate for about two hours for disinfection.

(2) sowing: when sowing, we should pay attention to the sowing density and dig a good planting hole, which is generally carried out in spring and autumn, and the seeds are evenly put into the hole. After sowing, cover about 2 cm of fine soil, and then pour enough water to do a good job of sowing management.

3. Seedling management

If sown in spring, it will be unearthed in about two months. During the seedling growth period, we should pay attention to the work of weeding by ploughing, not less than 3 times a year, and carry out inter-seedling work when the seedlings grow to about 12 cm, so as to ensure the healthy growth of seedlings. Keep the strong seedlings, on the contrary, remove the weak seedlings and replace the healthy seedlings with the same growth. At the same time, attention should be paid to topdressing and the prevention and control of diseases and insect pests to promote the healthy growth of Sapium sebiferum young trees. Through careful management, young trees can grow about 80 centimeters in that year and can be transplanted and planted after falling leaves in autumn.

4. Transplanting and planting

(1) when transplanting, the soil ball must be carried out, and the diameter of the soil ball should be kept at about 38 cm. Before transplanting, it is necessary to dig the planting hole and remove the gravel, slag and other sundries in the planting hole.

(2) apply sufficient base fertilizer, the base fertilizer is mainly fully mature farm manure, and then cover a layer of soil on the base fertilizer before planting.

(3) the main depth of planting is that the soil surface is about 8 cm away from the root of the seedling. Set up a support frame after planting, water it thoroughly, and water it again about three days after planting.

(4) according to the weather change and soil water content, the water and fertilizer demand of Sapium sebiferum is relatively large, so it is necessary to meet the nutrient and water demand of Sapium sebiferum.
