I. Main varieties of apricot trees Choose varieties with early maturity, good quality and strong self-pollination ability, such as Kate apricot, red purse, agate apricot and other varieties. II. Orchard establishment in apricot trees 1. Select the site to choose the leeward sunny, drainage and irrigation facilities, high dry terrain, sandy soil fertile land construction park. Each shed was cooked with 3000-4000 kg of manure, 15 kg of potassium sulfate, and 25 kg of apricot-specific fertilizer. Digging planting ditch, ridge on the ditch, the seedlings planted on the ridge, north and south line, spacing 12 meters. 2. The structure of the facility adopts a string-style solar greenhouse. East to west, length 50 to 80 meters, span 8 to 9 meters. The back wall is 1.6 to 2 meters high, the ridge height is 2.8 to 3.4 meters, and the rear roof is 1.2 to 1.6 meters long. The front roof is straight and the front wall is 1 meter high. The rear wall has eight 1-meter-high vents. The top vent is a two-piece membrane. When vented, the membrane and backslope connector are opened. Skeleton spacing 60 to 80 cm. The shed film is a longevity drop-free polyethylene film. Grass curtains are 3 to 5 cm thick, 1.2 to 1.4 meters wide, and 0.5 meters longer than the front roof. 3. Choose seedlings to choose seedlings with full shoots, thick branches, and complete and well-developed root systems. After the seedlings were selected, the roots were immersed for 24 hours before planting, and then the roots were soaked with 0.3% copper sulfate for 1 hour or sprayed with 3 Baumide Lithosulfur. The plants were sterilized and then planted. 4. Planting methods Planting time is best at the end of March and early April after the spring temperature rises. When planting, the seedlings are planted in the planned plots, and the seedlings are to maintain the extension of the roots. After the planting, watering, filming and set dry, dry high 40 to 50 cm. Third, cultivation technology measures 1. Prune trimming At the end of May and early June, dry and fixed tips are selected, leaving 7 to 12 tips with better angles, and the rest erased. When the new shoot grows to 40 centimeters, 2 to 4 tip cultures are selected for "V"-shaped or happy-shape pruning; for the rest of the new shoots, the tip is picked up, 2 shoots are made, and the upright shoots on the back are repeatedly picked up; Erased too densely. At the beginning of August, 2000 times of paclobutrazol was used to suppress the growth of new shoots and promote flowering, spraying again every 10 days. In the middle or late August, the branches were opened. Spray 10% to 12% urea in early November. Before the shed, remove too much and too dense branches, stand upright on the back, remove branches and branches, and adjust the structure of the tree. After the shed has warmed up, it carries out flowering cuts and cuts short some of the result branches that are too large to control the amount of flowers. Before the fruit enlarges until the fruit matures, it picks up many times for new shoots to control the growth of new shoots, increases the fruit setting rate and fruit weight, and can use the method of erasing or twisting shoots on the back upright shoots. After the fruit was harvested in the middle and mid-May, the growth balance of the tree was adjusted by means of retraction and thinning to prevent compensatory growth. 2. Flower and fruit management During the flowering period, greenhouses have high humidity and pollinators are not available. Artificial pollination is required. After flowering, 8 to 11 am every morning, flowers are pollinated by brush to increase the fruit setting rate. About 20 days after flowering, fruit thinning was combined to remove fruit and small fruit and deformed fruit. During fruit thinning, generally 3 to 4 fruit trees are left in the long fruiting branch, 2 to 3 fruit in the middle fruiting branch, and 1 fruit in the short fruiting branch, so that the fruit is evenly distributed in the canopy and reaches a reasonable load. 3. The principle of fertilizer and water management is to promote the post-control, that is to promote the main before July 15, after the main control. When the new shoot grows to about 15 centimeters in length, chase fast-acting fertilizers and alternate with foliar sprays. Top dressing 50 grams of urea per plant, foliar spraying of 0.3% urea or 0.4% to 0.5% potassium dihydrogen phosphate, spraying once every 10 to 15 days, 3 to 4 times in a row, after August, mainly phosphorus and potassium fertilizer, leaves Surface spraying of 0.3% potassium dihydrogen phosphate 2 to 3 times, the end of September to early October application of farmyard manure and compound fertilizer, chicken manure 500 kg per pot, 75 kg of potassium sulfate compound fertilizer. After the shed, 100 grams of urea were applied to each plant before germination, 100 grams of sulfuric acid compound fertilizer was applied to each plant after deferring until fruit expansion, and 0.3% urea and 0.3% to 0.4% phosphoric acid were sprayed every 10 to 15 days. Dihydrogen potassium. Irrigate three times, the first time around 20 days before the shed, the second time after the flower is poured with water as the soil conditions, and the third watering is at the hard nucleus stage. 4. Insect and disease prevention and control shed after the bud before spraying 3 to 5 Baume degree lime sulfur agent, prevention and control of overwintering pests and diseases, bell spur spray 1 time of flood control pesticides, eliminate aphids and red spider, growing season depending on the situation of pests and diseases, spray 1 ~ 2 times insecticide and fungicide. 5. The environmental conditions in the shed will be adjusted in early December. Pull up 1/3 of the grasshopper first, and then pull up 1/2 grasshopper, until the mid-December, pull the draft in the day and start warming up. During the 15 to 20 days before the temperature rise of the greenhouse, covering the mulching film, the ground temperature rises slowly. When the temperature rises in the greenhouse, the ground temperature and temperature are coordinated. After Xie Hua, in addition to mulching to prevent high temperature damage. Wiggle wire lock is designed to be used with poly lock base cap- sold separately. Greenhouse wiggle wire and base care are an effective method of attaching your poly film roof and or shade cloth. The greenhouse wiggle wire lock will hold form 4 mil to 20 mil thickness of material. Use one wire to hold the roof in place and then add a second wire to hold your shade cloth. When it is time to remove the shade cloth, you will not disturb the roof plastic.
