Planting method of hawthorn:
1, selective cultivation
Before planting hawthorn, it is very important to choose a planting plot. Hawthorn has a strong ability to adapt to the soil, but fertile soil and loose soil can promote the growth of hawthorn. The garden can be built in plains or hills, as long as the irrigation and drainage system in the garden is well done. Hawthorn can be planted all year round, but try not to plant it in winter. The temperature in winter is too low, which is not conducive to the germination and emergence of seeds, and its growth rate is also fast and slow, which will have a certain impact on the later fruiting rate and quality.
2, soil preparation and sowing
After selecting a good plot, then start to prepare the soil, turn the soil 15-20cm, spray chemicals for disinfection and then expose it to the sun for one month to eliminate bacteria and parasites in the soil. Then mix the base fertilizer with the soil, put it in the into the pit, put the hawthorn seedlings in the middle, and start to fill the soil, and gently step on it with your feet while filling it again. Let the roots of seedlings stretch better, contact the soil with a larger area, and enhance the absorption capacity of roots. After planting, pour enough root water, and the soil must be trampled to form a mound to prevent the seedlings from being blown down in windy weather.
3, intertillage and soil cultivation
During the planting process, according to the soil fertility and tree growth, the soil can be cultivated in time to improve the permeability of the soil, increase nutrients and promote the growth and development of roots. Then start fertilization, fertilization can not be a single fertilizer, but should be equipped with reasonable nutrients and balanced nutrition. Too little fertilization will make hawthorn trees lack nutrients, slow down the growth rate and affect the maturity and quality of fruits. Excessive fertilization leads to overnutrition, excessive branches, and early fruit drop, which will also have a certain impact on yield and quality.
4, plastic pruning
The branches of hawthorn have strong growth ability, and the failure to manage the branches in time will have a serious impact on the growth and development of the trunk. There is not enough nutrition supply, which makes the trunk very weak. Therefore, in the process of planting, we must prevent the increase of branches and the excessive growth of branches, cut off the branches with strong growth and diseased branches, and keep some branches with no excessive growth. Let hawthorn trees become stronger and grow better. When the crown branches of hawthorn grow to about 40 cm, cut them off by 30 cm and continue to grow. Too many branches will reduce both the growth of trunk and the permeability in tree.
