According to the author's many years of experimentation, the use of pomegranate tender shoots in the breeding of pomegranate seedlings in July has a high survival rate.
Breeding seedlings in the nursery to choose convenient open and flat land, requiring deep soil, fertile soil, moderate or slightly alkaline sandy loam soil is appropriate. Before planting, combine deep-turning 4,000 to 5,000 kilograms of organic fertilizer per acre and water it. After the surface is slightly dry, make it 1 meter wide and 20 to 30 meters long.
Cuttings are generally collected in the early morning or on a cloudy day with no wind. From the good mother plants with many results, good quality, and strong tree vigor, cuttings are removed from the rough shoots that have no l 0.8 to 1.5 cm is appropriate.
Before the cutting method, the cuttings that have just been cut or stored in the wet sand are cut, the stem thorns and the portions that are dehydrated and shrunk are cut, and then the long cuttings are cut into 12 to 15 cm from bottom to top. There are 2 Short cuts of ~3 sections. Cut a smooth slope at the proximal end of each cutting, which not only increases the contact surface with the soil, but also facilitates rooting. It also facilitates the identification of the upper and lower ends of the cutting insert to avoid reverse insertion. In addition, cut the tip of the cutting tip 0.5 to 1 cm away from the bud. Immediately after cutting, the cuttings are immersed in clean water for 12 to 24 hours at the bottom so that the cuttings are fully absorbed, and soaked in a solution of naphthalene acetic acid from 1510-6 to 2010-6 for 12 hours to promote rooting. When the cuttings are inserted, the cuttings are inserted into the soil at a spacing of 12 centimeters and 30 centimeters and inserted obliquely into the soil. The buds at the top of the cuttings are 1 to 2 centimeters from the ground. Watering immediately after cutting is completed so that the cuttings are in close contact with the soil. After the surface is slightly dry, loosen the soil immediately.
Post-insertion management timely irrigation: Rooting can be done 20 days after cutting, and soil should be kept moist during this period. When the film is dry, the film must be uncovered and watered in time. However, the watering should not be too much work, and the water should be poured in a small amount to prevent the mud from getting onto the young leaves or submerging the seedlings and affecting the survival rate. After the watering, it should be cultivated. During the rooting period of the cuttings, the loose soil will slam the cuttings and affect the rooting. Therefore, it is not appropriate to loosen the soil and remove weeds during this period of time. If too much grass can be removed manually. In addition to sprouting pods: When the pomegranate seedlings are about 10 cm tall, only one robust new shoot is kept, and all other sprouting pods are cut off. Topdressing: When the new shoot grows to 15 cm, topdressing 1 quick-acting nitrogen fertilizer, topdressing 15 kg of urea per acre, watering after application. In late July, top-dressing will be performed once. Afterwards, the amount of nitrogen fertilizer should be controlled, and phosphorus and potassium fertilizer should be properly applied to prevent leggy growth. In addition, in the growing season of the pomegranate seedlings, it can spray 3 to 4 times foliar fertilizer, with 0.3% urea solution in the early stage and 0.4% potassium dihydrogen phosphate solution in the latter stage.
