Common shed nectarines are shed in mid-December to mid-January of the following year. After the shed, focus on the following several management tasks.
1, temperature and humidity control. The temperature from the buckle shed to the pre-emergence temperature can be between 0-28°C. The germination period is 5-28°C. The flowering period is maintained at 10-15°C during the day (not to exceed 25°C) and not less than 7°C during the night. The fast-to-hard core shoots are 5-25°C. The fruit enlargement period is 10-25°C. The fruit coloring period is 15-28°C. Harvest period is 17-30°C. The relative air temperature from the shed to the bud should be kept at about 80%, and the flowering period should be controlled at 50%-60%. Afterwards, it should maintain 60%-70%.
2, watering fertilizer. Water should be poured after the shed to ensure proper temperature and humidity to facilitate germination. In combination with watering, each hole is topped with 0.3-1 kg of ternary compound fertilizer. After fruit set, water was poured in hard-core and fruit-inflated periods, respectively, and the water was topdressed twice in the hard-core and fruit-inflated stages. After the leaf is spread, a 0.2% solution of Cinhan liquid fertilizer, 0.1% of rare earth and 0.2% of Nongzhan No. 1 or No. 3 liquid fertilizer should be sprayed once every 10-15 days to increase the tree vigor and promote fruits. Expands, enhances coloration, improves yield and quality.
3, preserved fruit thinning. Artificial pollination or pollination by honeybees during flowering. At the flowering stage, a 50 mg/kg gibberellin + 0.2% borax solution was sprayed again to increase the fruit setting rate. Immediately 3-4 weeks after flowering fruits and vegetables, the results will be too much, too dense and deformed fruit, small fruit as soon as possible. Generally, 3-5 fruit-bearing fruits (30-60 cm long), 2-3 fruit-bearing fruits (15-35 cm), and 1-2 fruit-bearing short fruit branches (5-15 cm).
4, prevention and treatment of pests. The diseases and pests of nectarines in greenhouses are mainly anthracnose, black spot disease, aphids, and ticks. The specific prevention and control method is to spray the whole plant 1-2 times with 5 Baume degrees of lime sulfur after the shed, spraying 80% of Dasheng M-45 or 70% thiotoxin 600 once every 10-15 days after flowering. 800 times liquid, even spray 3-5 times. In the case of aphids and mites, 10% imidacloprid 2000-2500 times solution and 15% daptanone 1500 times solution were used for spraying.
