What should we pay attention to when planting cherries in greenhouse in summer? Experienced netizens are also invited to introduce in detail that the cherries are basically harvested in the summer greenhouse, and at the same time they have entered the blind period of cherry management, so the farming network has sorted out the key points of cherry management in the summer greenhouse, which are listed in detail below for netizens' reference. Point 1, cherry summer shears: greenhouse cherry summer shears are generally carried out when the film is removed, mainly to retract the cherry crown and carry out heavy strength pruning. 1. Retraction method: this method can reduce the overall height of each cherry crown by 50 cm to 80 cm respectively, preventing the tree from growing higher and higher, affecting the indoor ventilation and light transmission conditions. 2. Pruning and thinning method: this method mainly truncates and strengthens the main branch and cuts the mediocre main branch in the middle, so that it can be retracted to the middle or posterior branch, and then re-cultivated and developed into the main branch. 3. The method of fine pruning group: mainly through meticulous pruning of the main branch and each branch group and branch planted on the trunk, the dense chicken claw branch, erect branch, overlapping branch and peripheral competitive branch are removed, the medium and long branches are heavily cut, and the flat oblique mediocre branch group is retained. 4. Strengthen the cultivation of new fruiting branches: after re-pruning, many new buds and branches will be stimulated, and those with suitable positions should be cultivated into new main branches or fruiting branches, and those with inappropriate positions should be de-sprouted in time to clean up the layers. Key points 2, fertilizer and water management: 1. Topdressing and watering: fertilizing should be carried out in time after film removal. Between every two plants in each row, a fertilizer ditch with a depth of 30 cm, a width of 30 cm from north to south and a length of 100 cm from east to west should be dug, and each ditch should be sprinkled with 250 grams of nitrogen, phosphorus and potassium compound fertilizer. After sealing the soil, it will be restored to a high ridge, covered with plastic film, sprinkled on the film and sealed strictly. Combined with trenching, the exposed roots should be cut off, and the roots should be renewed and shrunk to reduce the amount of roots and control the expansion of the tree. When digging ditches, be careful not to shovel the agricultural film at the bottom of the ditch. Water should be watered once while fertilizing. The second fertilization is carried out in the middle and late September, and the fertilization ditch should be dug on the other side of the planting row. In the future, the operation can be rotated every year. 2. Extra-root fertilizer spraying: after removing film and shearing, combined with disease prevention and pest control, 1000 times liquid fruit tree special type "Tianda-2116" + 0.7% brown sugar + 0.3% urea solution was sprayed every 7-15 days for 3 times in a row. After the end of June, 0.4% potassium dihydrogen phosphate solution + 0.7% brown sugar solution + 0.3% urea solution was used alternately, spraying once every 7 days and 4 times in a row. Point 3. Spraying paclobutrazol on cherry trees: summer cherry trees can spray 200 times 300 times liquid 15% paclobutrazol every 10 to 15 days from the beginning of July, and spray 1% paclobutrazol 3 times in a row, so as to inhibit the growth of new shoots and promote flower bud differentiation. Point 4, timely drainage and waterlogging prevention: Cherry trees are afraid of waterlogging. Once the field is flooded, when the time is about 24 hours, the tree will die because of flooding. Therefore, after removing the film, it is still necessary to raise a high ridge, and the ridge surface is covered with plastic film to prevent waterlogging. When it rains, we should also pay attention to timely drainage, and it is strictly forbidden to accumulate water between rows in the shed. Cherry tree planting video cherry planting environment
