Selection of varieties: selection of medium- and early-finished cherry varieties for cultivation, usually with a range of 2-2. 5 x 3-3. 5 m
(c) large hut construction: usually covers the sheds around the third year after planting, and construction must take place after the cherry tree is dormant, i. E. Between late january and early february。
Temperature management: align the temperature of the shed to the growth phase to ensure that the shed cherries grow well。
Cherry trims: the tree shapes are generally hammered and year-round trims are completed during the summer. The building of the shed must be carried out before it can be built, and the new company must continue to take care of it for the long term。
I. How to grow cherry in the shed
1. Selection of varieties
(1) the choice of varieties is important and is a top priority for cherry cultivation。
(2) it is important to choose medium- and early-maturity varieties for garbage cultivation, and the logs may choose to be short-sized cherries。
(3) if costs are taken into account, it is also possible to use prune cherries, usually with a range of 2. 0-2. 5 x 3. 0-3. 5 metres, with different regional differences, but mainly based on dwarfation。
Construction of sheds
(1) the construction of the sheds must be determined according to the conditions of the shed facilities and the timing of the marketing of the fruits, and generally cover the sheds after the planting of the plants in the third year after they have grown to a certain amount。
(2) it is essential that the sheds use the archer vegetable sheds so that they are fully luminous and have an area of about 3 acres。
(3) the construction time must be from late january to early february, after the hibernation of the cherry tree。
3. Temperature management
(1) prior to the gestation, the temperature during the day must be around 18-20°c and at night around 2-5°c。
(2) at the flowering period, the temperature during the day must be around 20-22°c and at night around 5-7°c。
(3) during the period of fruit expansion, the temperature during the day must be around 22-25°c and at night around 10-12°c。
(4) during the harvest period, the temperature must be around 22-25°c during the day and 12-15°c at night。
Four, the cherries of the shed
(1) the light conditions under which the sheds are grown are poor, and it is important to choose a good light hammer。
(2) to complete the year-round exercise during the summer, it is necessary to pull branches and adjust the angle of the branches before building the sheds。
(3) in the long term, it is necessary to maintain a continuum of care and control of growth。
Ii. Temperature management methods for greenhouse cherries
1. Facing temperatures
(1) when managing the temperature of cherry growth, management is based on changes in the stage of cherry growth. At the time of flowering, the temperature should not be too high or too low for a more stable temperature to be maintained. The minimum temperature should be maintained at around 10 degrees, with particular attention to the temperature at night, and if it is too low, it must be increased in a timely manner。
(2) in the event of a clear day, be careful to act as a cooler and be equipped with thermometers in the shed. Temperature changes are regularly observed and must be reduced in a timely manner when the temperature is too high. For example, rising temperatures to 30 degrees reduce the vitality of cherry pollen and affect pollination fertilization。
2 temperature of the sibling period
(1) it has just been said that the temperature will be adjusted as the stage of cherry growth changes. The temperature will remain at about 18 degrees after the cherries begin to sit on the fruit when they enter the season。
(2) the temperature then gradually rises to about 22 degrees after the pre-development of the cherries and when the flower starts to swell。
(3) the temperature cannot exceed 30 degrees, otherwise there will be significant effects on the growth of the cherry. It is also necessary to keep the temperature of the day and night at around 8 degrees at night, up to 10 degrees。
3. Enrichment period temperature
(1) after the cherry-sitting fruit, over time, it slowly enters the booming period of the fruit. The temperature must not be too high in the period of cherries ' expansion, otherwise it will not only affect the expansion of the fruit, reduce its quality, but also lead to the appearance of the fruit, for example。
(2) temperature is to be contained at around 23-24 degrees during the period between the colour of the fruit and its maturity. The temperature difference between day and night is maintained at around 10 degrees, and the appropriate temperature is favourable for the colour and expansion of the fruit。
4. Temperature control
(1) the temperature and humidity of the cherries in the shed can be regulated through vents or defilms. Temperature regulation directly affects the production of cherries in the pre-growth period, while later temperatures directly affect the quality of the temperature。
(2) at the beginning of the warming to the flowering period, the temperature is increased appropriately, usually for about a month or so, and if the temperature rises quickly, the flower may start to bloom in about 25 days, although there will be a more severe drop。
