High-yield cultivation techniques of Sapium sebiferum

Sapium sebiferum is a deciduous tree of Euphorbiaceae. Sapium sebiferum is a kind of economic tree species with bright and colorful colors and high ornamental value. It has been cultivated for nearly 1500 years in China. And the root bark, bark and leaves of Sapium sebiferum all have certain medicinal value, such as detoxification, diuresis, detoxification and so on. They are mainly used to treat injuries caused by falls and snakebites. So how to grow Chinese tallow? The following editor brings you the cultivation techniques of Sapium sebiferum. Let's have a look!

1. Harvest seeds

The seeds should be harvested before planting. In order to ensure the germination rate of the seeds, we should ensure that the age of the mother plant is more than 18 years. 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

The wax on the seed coat should be removed before sowing to improve the germination rate. First of all, put it into the container, use about 55 degrees warm water to add laundry detergent, 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. When sowing, we should pay attention to the planting density to dig a good planting hole, generally in the spring and autumn, and put the seeds evenly 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

After sowing, it is necessary to strengthen the water management of the seedbed. If you sow seeds in spring, they 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

When transplanting, the soil ball must be carried out, and the diameter of the soil ball is 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. Then 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. The depth of planting is mainly about 8 cm from the root of the seedling on the soil surface. Set up a support frame after planting, water it thoroughly, and water it again about three days after planting. Then according to the weather changes and soil water content to control the watering frequency and dosage, the water and fertilizer demand of Sapium sebiferum is relatively large, so it is necessary to meet the nutritional and water needs of Sapium sebiferum when planting.

In the process of planting, it is necessary to keep the soil moist to prevent water shortage. if there is a shortage of water in the growing period of Chinese tallow, it should be watered immediately, otherwise Chinese tallow will grow badly because of lack of water. In addition, we should also pay attention to the prevention and control of diseases and insect pests, prevent diseases and insect pests from affecting the growth of Sapium sebiferum, and reduce the economic benefits of planting.
