Hawthorn is made of ripe and dried flesh, and it is mainly produced in Zhejiang, Henan and other provinces.
Habitat Hawthorn hi warm and humid climate, the general soil can be planted, but moderate and slightly acidic soil is appropriate.
Cultivation technology selection land preparation: After the selection of nursery land, in the fall and winter, apply fertilizer 3500-4000 kg per acre, superphosphate 50 kg, deep cast after the application of 30 cm, fine leveling. Shallow plowing before sowing, fine leveling, making a 1.2 meters wide sorghum, sulcus width 40 to 45 cm. It is advisable to select leeward sunny slopes and riverside lands for the planting sites, and it is advisable to plant terraces in the mountains to prevent and control soil erosion. Propagation methods: The main method is seed propagation. Cutting methods such as cutting, layering and grafting can also be used. Seed propagation is carried out from late September to early October. In the vigorous and productive mother plants at fruit stage, red, large and flesh-colored fruits are selected, the flesh is peeled off, the seeds are washed, the impurities are rinsed, and the grains are rinsed. Seed, immediately sowing (Sun-dried seeds are not easy to germinate). Can also be sowed in the early spring of the following year. On the seedbed, a groove with a spacing of 20 to 25 centimeters and a depth of 3 to 5 centimeters is to be planted, and the seedlings are planted at a spacing of 10 centimeters. After sowing, the cover soil is slightly repressed, then the grass is covered and watered to keep the surface moist. Use 6 to 10 kg per acre. Cultivate 2 to 3 years, when the seedling height 60 to 80 cm can be planted. The colonization period should be carried out after autumn leaves or before spring sprouting. On the planting ground, dig a hole at a spacing of 2.5 meters and 2 meters, the depth and diameter of each hole are 50 centimeters, apply 15 kilograms of fertilizer and 15 grams of superphosphate per hole, 50 grams of superphosphate, plant one seedling per hole, and cover the hole with soil after planting. Around the building a ring of soil. Grafting was carried out in July-August, using T-shaped buds. The rootstock for grafting is selected from the 2-year-old seedlings of the good cultivar of Hawthorn, and the stalks are selected from the shoots on the mother plant of the robust and productive motherland in the full fruit period.
Field management tillage weeding: After colonization and survival, each year cultivator weeding 4 to 5 times, spring weeding to diligence, loose soil should be shallow, so as not to hurt the roots; in summer and autumn, the number of weeding less, deeper soil; early winter tillage weeding, To combine soils to ensure safe wintering. Top dressing: Combine with cultivating and weeding, top dressing 3 to 4 times a year, reapplying in spring and autumn, mainly organic fertilizer. Flowering and fruit setting spraying with 0.1% boric acid solution and 0.5% potassium dihydrogen phosphate solution to facilitate flowering results. Irrigation and drainage: Watering should always be performed after planting to keep the soil moist. The adult plants poured 3 times of water, the first time before flowering in the spring, the second in the summer fruit filling period, and the third time before the winter freezing. There is accumulated water in the rainy season and it should be eliminated in time. Pruning: The pruning of saplings begins with cultivating the sturdy trunk and deciding on the trimmed tree. The young trees are usually about 70 cm high and the final height of the tree is controlled at about 3 meters. In the first year, 3 to 4 robust lateral branches distributed uniformly and grown in different directions were selected and cultured as the first main branch, and the remaining branches were all cut off from the base; in the fall of the second year, the main branch from the first layer was 50 to 80 cm to stay in the distribution of uniform Zhuangzhi 3 ~ 4, training into the second main branch; the third year in the 50 meters away from the main branch of the second layer, the election reserved Zhuangzhi 3 ~ 4, training into the third The main branch. The pruning of saplings should master the principle of more sparse shearing and less short-cutting, so that the tree can be shaped as soon as possible. Poor growth saplings should master the principle of keeping more branches and less sparse shear. The pruning of adult trees should be based on the maintenance of a strong tree vigor and the cultivation of more results. The principle of short shearing and thinning and shearing should be mastered.
