Cultivation and Management of Heyin Pomegranate Seedlings

Breeding 1. Cutting Propagation 1) Selection of Cuttings: Tender shoots are used for cuttings. Because the tissue is tender, the growth is strong and the results are late. The use of long branches or Wang branches for cuttings is not easy to take root, and the results are also late. When the result is used as the mother branch or the last year's result branch as the cutting, the future growth will be poor and the life span will be short. When cuttings with more than three years of age are inserted into the flowering period, the canopy is not easy to grow and cannot produce high yields. When using the older branches for cutting, the survival rate is not easy to be low, and the best cutting is Grey-white, 1-2-year-old shoots from a sturdy tree. Its diameter is 0.5-1CM. 2) Cutting period: pomegranate branches do not have to be stored, and they can be picked from the tree and can be cut. As long as the temperature and humidity are appropriate, all seasons can be. However, because of different regions, the cutting and burying are changed, and the spring and autumn seasons in the north are good. . Spring is in late March until the bud. Fall is better from October to November. The autumnal plug is better than the spring plug, and the autumn plug branches have sufficient nutrients, and the low temperature and moisture are not easy to evaporate, which is conducive to rooting and survival. However, autumn is too early to insert, and it is easy to be frozen in winter. 3) Cutting method: The field requires sand permeability with strong permeability and 5,000 kg of fertilizer per acre. Deep-turning, leveling, strips, width 1M (Squatting surface 0.8, stalks 0.2M) 4 lines per plant, spacing 15CM. The cuttings are 15cm long, and compacted, watered, sprayed with herbicide, and covered with plastic film. After germination, the plastic film plugs will grow. 2. Seed propagation - When the seeds are harvested from August to September, they are picked. Remove the seeds, remove the rind, dry them and store them. The seed and river sand can be mixed in a ratio of 1:5 and stored. Seed sowing in spring from March to March. Before sowing, the seeds were soaked in warm water at 40°C for 6 to 8 hours until the seed coats expanded and then sowed. This treatment is conducive to early seed germination. The soaked seeds were sown in the culture soil at a 25 cm line spacing and covered with 1 to 1.5 cm thick soil. Above the grass, pouring a permeable. Afterwards, the basin soil is kept moist and the soil temperature is controlled between 20°C and 25°C. After about a month, new shoots and new roots can be issued. Seedlings were managed at a seedling spacing of 6 to 9 cm when the seedlings were 4 cm high. Weeding water was applied after the weeds were removed from June to July, and phosphorus and potassium were topdressed in August. Anti-drought in summer and antifreeze in winter. After transplanting leaves in autumn, it can be transplanted before sprouting next spring. 3 layering method to reproduce a small area to develop seedlings. The long branches of the roots of large trees are usually used to dig pits in situ and arched from branches. The ends of the bow are buried with soil, and the pits are retained after being buried. Water is continuously applied to keep the soil moist at the fillets. , about 40 days can take root. After the rooting, the mother is cut off and allowed to grow naturally. After 20 days, it can be transplanted. The top of the bow was cut before transplanting, and each burying point was further divided into two (cut according to the root condition).

[Post-planting management] Spring can be watered 2 times depending on weather conditions. In mid-to-late and late June, 150-200 grams of compound fertilizer is applied per plant and watering is performed at the same time. It is necessary to carry out cultivating and weeding regularly to keep the park clean. After deciduous, the cold-resistant genus is used according to the decrease in the local temperature, which is usually done from late November to early December. The cold-proof method, when saplings first, pushes the trunk up to 30cm thick. The second is to put the main soil 50cm. After three years of life, trees can only be well-grown with trunks. After thawing, remove it.

【Management after harvesting pomegranate trees】 Apply a reasonable fertilization to increase tree vigor: After plucking the pomegranate garden, apply 0.5% urea and 0.2%-0.4% potassium dihydrogen phosphate every 10-15 days. According to the age of trees, tree vigor and the results of the year the state of fertilization. 2-3 years old pomegranate trees apply 2.5 kg of phosphate fertilizer or 2-3 kg of fruit-specific fertilizer, soil miscellaneous hypertrophy about 100 kg. Available ring groove, radiation groove, application, top dressing and other methods. The second plowing weeding, cleaning the tree plate: the tree plate plough depth of about 20 cm, and then gradually deepens from the inside out, to remove the weeds and litter within the tree tray, and further enhance soil permeability, activation of root physiological functions. Pour frozen water before wintering. 3. Spraying pesticides to prevent pests and diseases: After harvesting, the whole garden must be sprayed with 800 times 40% carbendazim suspension or 50% WP wettable powder 800 times in time to eliminate dry rot and pathogenic bacteria in the garden.
