How to manage the temperature of cherries in greenhouse

Cherry is a kind of fruit with expensive market price, but there is still a very large market demand in China. At present, cherry planting methods are generally based on greenhouse planting, and when we plant greenhouse cherries, management work is very important. Especially the temperature management, so greenhouse cherry how to manage the temperature? Today's small series will give you a brief introduction. Let's take a look at it together.

1, flowering temperature

When we manage the cherry growth temperature, we should manage it according to the change of cherry growth stage. In flowering time, to maintain a relatively stable temperature, the temperature should not be too high or too low. The minimum temperature should be kept at about 10 degrees, especially at night. If the temperature is too low, it must be heated in time. Then encounter sunny days, also pay attention to ventilation and cooling work, in the shed should be equipped with a thermometer. Often observe temperature changes, temperature is too high, must be timely cooling. For example, after the temperature rises to 30 degrees, it will reduce the vitality of cherry pollen and affect the pollination and fertilization rate.

2. Temperature during fruit setting

As mentioned earlier, we need to adjust the temperature appropriately with the change of cherry growth stage. After the cherries enter the fruiting period and begin to set, the temperature should be maintained at about 18 degrees. Then in the early stage of cherry fruit development, and after the flower drops to the young fruit begins to expand, the temperature gradually rises to about 22 degrees. The highest temperature can not exceed 30 degrees, otherwise the growth of cherries will have a very large impact. And also to maintain a good temperature difference between day and night, night temperature control at about 8 degrees, the highest can not exceed 10 degrees.

3. Temperature during expansion period

After cherry fruit setting, with the passage of time, it will slowly enter the fruit expansion period. In the cherry fruit expansion period, the temperature must not be too high, otherwise it will not only affect the fruit expansion, reduce the quality of the fruit, but also lead to fruit drop and other phenomena. During the period from fruit coloring to fruit ripening, the temperature should be controlled at about 23-24 degrees. The temperature difference between day and night should be kept at about 10 degrees, and the appropriate temperature is very beneficial to the coloring and expansion of the fruit.

4. Temperature regulation

The temperature and humidity of greenhouse cherries can be adjusted by ventilation or film removal. In the early growth period of cherry, temperature regulation directly affects the yield of cherry, and later temperature directly affects the quality of temperature. At the beginning of the warming to flowering, to increase the temperature appropriately, this period is generally about a month, if the warming rate is fast, then about 25 days may begin to bloom, but there will be more serious flower drop phenomenon.

The above is a simple introduction to how to manage the temperature of greenhouse. Today's introduction is here, this article is for reference only, I hope to help everyone oh!
