First, scientific site selection.
Hawthorn has strong vitality and adaptability. It is better in sandy soil, worse in cohesive soil or saline-alkali soil, and neutral or slightly acidic is the best. It needs deep soil, plenty of light and convenient transportation. It can be planted properly under the condition of sufficient water, fertilizer and light.
Second, scientific seed selection.
The planting varieties are Da Jinxing, Da Wuling, Da Mianqiu, etc. 18. Seedling should have a complete root system, with more than three bare roots evenly distributed, the length of bare roots is more than 25cm, and the number of roots should be as large as possible, and attention should be paid to ensuring that there are no root pests such as nodules. The grafting interface of seedlings healed well. The diameter of 5cm above the grafting interface is greater than 1cm, the seedling height is greater than 1 m, there is no branch disease, pests and diseases, the branches are mature and the buds are full. When the seedlings are very different, they should be classified according to size, and the damaged parts of the roots should be cut off. If there are plastic strips in the grafting parts of seedlings, they must be removed, otherwise it is easy to hang seedlings.
Third, planting density.
Seedlings should be sown before autumn leaves are frozen and before spring thawing and germination. The row spacing of fertile land is 4m × 4m or 5m × 4m. The hillside distance is 4m × 4m or 4m × 3m. Planting in the north-south line is beneficial to ventilation and light transmission between hawthorn trees. When the foundation pit is excavated, the excavated topsoil and core soil should be stacked separately. The hole is 80 cm deep and 100 cm in diameter. After digging the pit, 75 kg of miscellaneous fertilizer is applied to each pit, which is mixed with the topsoil and filled into the pit. At the same time, fill it to about 27 cm from the ground, a little higher in the middle. Put the planted hawthorn seedlings in into the pit, compact the root soil, and then compact. After filling the tree hole, build a ridge around the tree hole, water it and keep it moist until it survives.
4, selecting mating pollination trees
In order to significantly improve the seed setting rate and yield, late-maturing hawthorn varieties or wild hawthorn with similar flowering period should be selected as pollination trees. For example, pollinators in some areas of Dashan should choose wild hawthorn with big fruit and late maturity (this area is called late red). The ratio of main varieties to pollinated varieties is (5 ~ 10): 1.
Verb (abbreviation of verb) is intercropped reasonably.
In the first three years after planting, short-stalk crops such as potatoes, melons, peanuts and medicinal materials can be interplanted to increase income, but long-stalk crops such as corn cannot be planted. Natural grass can be used after 3 years. Pay attention to the removal of harmful weeds, such as Artemisia, quinoa, flax and so on.
