Shelter Black Red Brown Technology

First, preparatory work before planting According to the east and west walls to leave 1.5 meters for the ditch centerline, the distance between the centerline of the two ditch is 2 meters, dig deep and 80 cm wide horizontal groove. Fill the first layer of the ditch with 20 cm thick organic matter, mix the second layer of manure with topsoil in 1:2 to 3, and add 0.5 kg of methyl isofluosaphos granules to each groove to fill 20 cm of the ditch (each 6- to 7-meter-long ditch with 100 kg of manure), the third layer backfill all the soil, and made squat, water permeable ditch. Second, the planting density of 0.8-1.0 meters 2 meters, 400 acres per acre. Before planting, the roots of seedlings should be soaked in fresh water for 12-24 hours. After the rooting powder and the resulting mud, the seedlings should be planted. During the colonization, the roots of the seedlings should be flush with the ground. After planting, sufficient water should be poured and irrigated on the third day. Once, the water is covered with earthen film. Third, the main tree in the shed 1, 丫 shape: The first row in the shed more than the use of the tree. Dry height 20 cm, the main branch of the two things and the ground into 45, the main branch directly on the results of Zhizu. 2. Happy-shaped: The second and third rows in the shed use this tree. The stem is 20-25 cm high, and the three branches that are evenly growing are chosen as the sovereign. The angle between the main branches is 120, the angle between the main branch and the ground is 45, and the result is directly generated on the main branch. 3, spindle: suitable for the last 2-3 rows in the shed. The last row of trees is usually up to 1.8-2 meters, leaving 3-4 branches, the front row is gradually reduced by one layer, spindle-shaped three main branches per layer, the upper layer interspersed with the gap of the lower branches, each main branch are single The shaft extends 70 to 80 centimeters into the center. Fourth, the management of the year of colonization 1, dry front row 30 cm, rear row 45 cm, each row into a slope cut the upper part. 2, wipe buds, twigs and new shoot management (1) 丫 shape: When the new shoots grow to about 2-3 cm when the buds. Remove all sub tips less than 20 cm from the ground. Select the left and right sides of the new shoots to make two main branches. When the remaining shoots grow to 25-30 cm, they will grow flat and control the growth. They will pick up more than 30 centimeters and will soften the branches. When the two main branches grow to 40-50 centimeters by the end of June, leave the lateral buds to take care of the head. The rest of the auxiliary shoots go to the upright branches and leave the oblique branches. Leave about 15 centimeters on the main branch. (2) Happy shape: When the new shoot grows to 2-3 cm, wipe the buds, select the three new shoots that grow similarly to be the main stick, and erase the rest. When the new shoot grows to 40-50 cm, leave the buds Topping, the main branch anticline shoots leave every 15 cm, excess erase. (3) Spindle shape: When the new shoot grows to 2-3 cm, it chooses to leave an upward tip as the center stem, and the center dryly selects the first layer of the main branch in three directions. The center extends the length of the head to 60 cm. Pick up the heart, promote branching, and leave 1 standing branch as the central stem, and then select three interspersed first-level main branch voids to make the second-level main branch, erase the remaining auxiliary tips, and so on to leave the third layer. The fourth floor. 3. Spraying growth inhibitors to promote flower bud differentiation If tree vigor is available in late June, it may be delayed until July 20. There are two kinds of agents, one is paclobutrazol, spray concentration 150-200 times, the other is pbo, concentration 100 times liquid, depending on the situation, spray 2-4-4, interval 7-10 days. 4, fertilizer and water management (1) When the new shoot grows to 10 cm, began to top dressing, mainly urea, 10-15 days once, about 50 grams per plant, after gradually increase the amount, after the middle of July, phosphorus and potassium fertilizer, Potassium sulphate or potassium dihydrogen phosphate, about 100 grams per plant, perfusing water after top dressing. (2) In the autumn, the base fertilizer is mainly organic fertilizer with sufficient decomposability. It is applied in the ditch with a width of 40 cm in the periphery of the canopy, and the water is poured after the application.
