Greenhouse peach sheds forced dormancy, usually from mid-October to mid-November. The management of the 10 days before the hibernation was forced to sleep was very important. The management was not good, and it directly affected the improvement of fruit setting rate, yield and quality. The key management measures for this period are as follows: Foliar spraying fertilizer forced dormancy 10 days before, spraying 3% - 5% of the high concentration of urea solution, and add adhesives, penetrants, such as synergy and special effects king Let the tree quickly absorb certain nutrients, so as to lay a good foundation for later germination and enlargement, peach blossom. The spraying time should be carried out at 4 pm, pay attention to uniform spraying. Adding base fertilizer to increase base fertilizer is carried out 9 days before dormancy. Greenhouse peaches have a longer growth period than open-field peaches. Fertilizer application and frequency of fertilization also need to be increased and increased. Mushi organic fertilizer is applied for 4,000 kilograms. Fertilizer application amount is for the whole year. Half of the dosage, 0.2 kg per plant, the ratio of nitrogen, phosphorus and potassium is 10:3-4:13-16, which can be applied first to fertilizer and then to coarse fertilizer, deep-turning 10-15 cm. Can also ditch, in the middle of the two rows of peach trees (half the spacing of 1-1.2 meters) ditch, deep 10-15 cm, width 20 cm, buried deep after the strict practice. On the third day after fertilization, water should be poured, but it should not be too large. Then cover the mulch, and then in the young fruit period, hard nucleus, and mature water each pouring 1 times, to meet the water needs of peach. On the third day after the watering, the third day after the watering of the peach mulch is covered, the black mulch with the same width as the peach tree is covered, and the joint between the membrane and the membrane is pressed with soil, or with fine branches on the membrane. The edge is firmly inserted to prevent the wind from lifting the film. Two days before the dormancy of the temporal lobe, we must squat up from the base of each shoot. For those leaves that are not well controlled or tender in the summer, we must gently smash the leaves so that they do not stay. After the squatting, the leaves were cleared out of the shed. You can spray the medicine after spraying it. Peach mainly suffers from perforation, scab, and fluid injection. It can spray 100 times 65% of dexamethasone or 50% of methadone or 9281. Insect pests mainly include leafhoppers, aphids, leaf leaf moths, etc. They can be sprayed with 800-1000 times liquid infestations to prevent and treat them. Fungicides and insecticides should be evenly sprayed onto the trunks and branches of peach trees in order to reduce the source of infection of pests and diseases.
