The latest course of disease-free seed planting techniques and methods

They are deciduous trees, mainly distributed in the Yangtze River Basin and Indo-China Peninsula. Its fruit is rich in diosgenin, can replace soap, is the raw material of soil detergent, root, skin, branches and leaves, pulp, seeds can be used as medicine, with heat-clearing, expectorant, accumulation, insecticidal effect. In addition, the oil content of the seed is up to 43%, which is the raw material for the manufacture of diesel oil and lubricating oil, and its economic value is very high. Let's take a look at its planting technology.

1. Seed selection and nursery

There are many varieties of disease-free seeds, each variety is different, the yield of different varieties is different, diosgenin and oil content are also different, so the selection of good varieties is a major event before planting, and good varieties must be selected. The seeds are stored at the end of the year, planted after the beginning of spring next year, soaked in warm hot water for a day before planting, and then sowed with the technique of sand bed germination, so that the germination rate is high. The seedlings grow very fast after they are unearthed, and they can come out of the nursery in one year, and the propagation methods such as cuttings and root buds can also be used, or the grafting method can be used to cultivate excellent plants.

2. Select land for afforestation

The disease-free son is a light-loving, deep-rooted plant, and the sex likes the environment with sufficient light, so it is appropriate to choose sunny sloping land or semi-sunny sloping land to plant, requiring a slightly acidic soil with deep soil layer, loose and fertile soil and good drainage. After selecting the forest land, clean up all aspects of it in autumn, clean up weeds, shrubs and other plants, and clean up dead branches and leaves. After being done, the planting points were excavated according to the plant spacing of 4 × 4 meters, with 60 × 60cm on the surface, 40cm in the depth and 50 × 50cm at the bottom of the acupoint. In January, about 3 kg of barnyard manure, compost and other organic manure were applied to each hole as base fertilizer, and a layer of soil was mixed after fertilization to be transplanted.

3. Colonization

Dig up the young trees that have been cultivated for a year, be careful not to hurt the roots of the seedlings, and then take them to afforestation and transplant, so as to ensure the survival rate. Put the young tree Fuzheng into the planting hole, expand the root system in the planting hole, do not twist together, in the filling, fill to the middle of the planting hole, lift the young tree up, make its root system stretch, then fill and water.

4. Forest management

After the young trees were planted and survived for one month, they could be fertilized every half a year, mainly nitrogen fertilizer combined with phosphorus and potassium fertilizer, and the amount of fertilizer should be increased according to the tree age. In the management, we should pay attention to the change of moisture, no sick children are afraid of waterlogging, pay attention to drainage in the rainy season to avoid stagnant water causing rotten roots, and timely watering when the young trees grow to 1 meter, prune and shape the terminal buds in time, cut off the terminal buds, retain the trunk, promote the growth of lateral buds and form a tree crown, which can increase the yield.

The above is the disease-free tree planting technology, hope to help you, want to know more planting knowledge, please follow us.
