First, focus on summer cuts. While removing the film, the crown must be retracted in time for heavy intensity trimming. 1. Fall back to the central leadership. This method can reduce the overall height of each cherry tree crown by 50-80 cm, preventing it from growing taller and affecting indoor ventilation and light transmission conditions. 2, cut off, remove the main branch. It is necessary to cut back the strong main branch and the middle main branch, allowing it to retract to the middle or rear part of the birthplace, and to re-cultivate and develop the main branch. 3. Finely cut each stick. We must meticulously prune the branches and branches of the main branch and the main stem, and weed out the dense chicken legs, upright branches, overlapping branches, and peripheral competition branches, cut short and medium long branches, and keep the meandering meandering branches. 4, training new results sticks. When the tree body is recut, it will inspire many new shoots and new shoots. If the part is suitable, it should be cultivated into a new main branch or result branch group; if it is inappropriate for the part, it should be promptly removed and cleaned. Second, fertilizer and water management 1, top-dressing watering. After fertilizing the film, fertilize in time. Between each two plants in each row, dig 30 cm deep, 30 cm wide from north to south, and 100 cm from east to west. Fertilize the ditch with nitrogen, phosphorus, and potassium fertilizer 250-300 per ditch. G, after sealing the soil, it was restored to a high ridge, covered with plastic film, and soil was dripped and sealed. It is necessary to combine the trenches to cut the roots that have been discovered after excavation, and to renew and shrink the root system so as to reduce the root volume and control the expansion of the tree body. When digging trenches, be careful not to scab the bottom of the agricultural film. Apply water while fertilizing. The second fertilization is carried out in the middle and late September. The fertilization ditch should be excavated on the other side of the planting line. Afterwards, the annual rotation will be sufficient. 2, root spray fertilizer. After removing the membrane and shrinking, combined with disease prevention and extermination, spray 1,000 times of fruit tree-specific “Tianda-2116â€+0.7% brown sugar+0.3% urea solution for 3-4 times every 7-15 days. After the end of June, use 0.4% potassium dihydrogen phosphate solution + 0.7% brown sugar solution + 0.3% urea solution and use it alternately. Spray once every 7-10 days, and spray 3-4 times continuously. Third, spray paclobutrazol. From the beginning of July, spray 200-300 times 15% paclobutrazol every 10-15 days, spray 1-3 times in succession to suppress shoot growth and promote flower bud differentiation. Fourth, drainage flood control. The cherry trees are afraid of picking, and once the field has accumulated water, the trees will die due to flooding when the time is about 24 hours. Therefore, after removing the film, it is still necessary to raise a high ridge, cover the mulch with a mulch, and use a waterproof rake. When it rains, it is also necessary to pay attention to timely drainage, and it is forbidden to accumulate water between the sheds.
