It is important to make good choices for profit In the production, the main choice of land early ripe peach, or late ripe peach cultivation. In order to be listed in advance, it is recommended to choose early maturing, extremely early maturing varieties; to select varieties with low calorie intake, the time for natural dormancy is short, and the time for warming the canopy can be correspondingly advanced, and the fruits mature earlier; Flower buds, pollen volume, self-flowering rate, adaptability varieties. In addition, we must choose a dwarf tree with a compact crown and a flower bud that can produce flowering results the following year. Nectarine seedling transplanting attention å•¥ The construction of sheds in the nectarine garden does not require transplanting, and the management of fertilizer and water can be strengthened. Before the transplanting of the new greenhouse nectarine seedlings, it is necessary to deepen the soil and apply 4,000 to 5,000 kilograms of high-quality organic fertilizer to each shed. Dig 60 cm in depth and 80 cm in width to form a planting ditch, north-south direction, plant spacing 1.5 meters 4 meters, watering after planting, and covering the mulch. Nectarine nectar temperature and humidity control is most suitable The nectarine flowering period of the greenhouse: It is required that the daytime temperature is controlled at 10°C to 28°C, and the temperature should be maintained at 5°C to 10°C at night, and the humidity should be maintained at 70% to 80%. Young fruit period - hard core period: The daytime air temperature is controlled at 15 °C ~ 25 °C, night at 8 °C ~ 15 °C, humidity 50% ~ 60%. Fruit enlargement period - Harvest period: The daytime air temperature is controlled at 15 °C ~ 30 °C, the night temperature is controlled at about 10 °C, and the humidity is kept at 60%. The nectar in greenhouses is the key to producing thin fruits and thinning fruits Sparse fruit thinning is an important measure to increase the fruit setting rate and fruit quality of nectarine in greenhouses, especially for nectarine trees under the conditions of facility cultivation. Flowering time is often affected by factors such as temperature, humidity, light, and pollination, and fruit setting is unstable. Therefore, the thinning and fruit thinning of nectarines in greenhouses should be based on the principle of “light sparse flowering and heavy fruit thinningâ€. Sparse flowering time is best in bud stage. In the case of a large number of flower buds, most flower buds and long-medium fruiting branches on thin and thin branches can be sparsed, and double flower buds that are longer due to longer cuts, as well as late flowering buds that are stunted. Fruit thinning 1 fruit thinning period. The fruit peeling is generally performed twice. For the first time in 3 to 4 weeks after flowering, nectarines were made as large as apricot kernels. The second fruit-shredding is the fixing of the fruit, which is carried out after the nectarine hard-core period, and will dredge the overloaded fruit. 2 amount of fruit left. The amount of fruit left should be determined based on the fruit set rate, size, tree vigor, and tree size of the nectarine varieties. Generally, 4 to 6 fruit branches are left, 3 to 4 fruits are left in the middle fruit branch, 1 to 2 fruit are left in the short fruit branch, and 1 fruit or fruit is left in the bouquet-like fruit branch, and the fruit is prolonged. 3 thinning method. It should be based on the principle of "reserving excellence and reducing the inferiority." Peach fruit on the same branch spacing of about 10 to 15 cm. Remove malformed fruit, small fruit, pests and diseases; stay lateral, lower position fruit, sparse on the fruit; leave strong fruit, weak fruit. The order of fruit shrubs should be from the inside to the outside, and from top to bottom, branch by branch, in order to prevent leakage or damage the fruit. Greenhouse nectarine management Temperature and Humidity: The daytime temperature in the shed should be maintained at 23°C~28°C, and the minimum temperature at night should be kept at 15°C. The humidity in the booth should be maintained at 50% to 70%. When the humidity is too low, spray water to humidify before sunset. Coloring period to increase the temperature difference between day and night, usually day and night temperature requirements in the 10 °C ~ 12 °C. Fertilizer water clearance: Apply about 125 kilograms of compound fertilizer per acre (each plant applies 0.25 kilograms), apply a hole or ditch, apply water after fertilization, and dry and wet the soil evenly. Combined pest control, spraying 0.3% ~ 0.5% potassium dihydrogen phosphate 2 ~ 3 times. In addition, you can spray fruity red, red fruit 88 and other fertilizers to promote fruit enlargement and coloring. Xia Jian Guan: The task of Xia Jian is to improve lighting and control new shoots. One is to continue topping up the new shoots. The second is the retraction of excessive branches. The third is to leave 1~2 leaf weights for the leggy branches with space, and to eliminate those without space. The fourth is to remove the leaves within 5 cm around the fruit.

The greenhouse nectarine tube has good quality and high yield
Cold weather, shelter has been shed. Nectarine is no exception. Speaking of nectarines in greenhouses, we cannot but speak about its effectiveness. The cultivation of nectarines in greenhouses has yielded considerable benefits. Therefore, there are more farmers growing nectarines in greenhouses. So, how to produce good-looking and delicious nectarines has become a problem faced by many fruit growers. This issue of the "Orchard Management Greenhouse Nectarine" edition will be selected from the nectarine species in the greenhouse to the nectarine shed. This will introduce the management techniques for nectarines in greenhouses and hopes to help farmers.
