How to manage the temperature of cherries in greenhouse

Cherry is a kind of fruit with high market price, but there is still a great market demand in our country. Now the cherry planting method is generally based on the greenhouse, and when we grow cherries in the greenhouse, the management work is very important. Especially the temperature management, so how to manage the temperature of greenhouse cherries? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Flowering temperature

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

2. Temperature during fruit setting period

As I just said, we should adjust the temperature appropriately with the change of cherry growth stage. After the cherry enters the fruit-setting period and begins to set fruit, the temperature should be kept at about 18 degrees. Then in the early stage of cherry young fruit development, and after falling flowers to the young fruit began to expand, the temperature will gradually rise to about 22 degrees. The highest temperature should not exceed 30 degrees, otherwise it will have a great impact on the growth of cherries. And also to maintain a good temperature difference between day and night, the temperature at night is controlled at about 8 degrees, the highest can not exceed 10 degrees.

3. Temperature during expansion period

After the cherry sits on the fruit, 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 control

The temperature and humidity control of greenhouse cherries can be adjusted by means of vents or uncovering film. In the early stage of cherry growth, temperature regulation directly affects the yield of cherry, while the temperature in the later stage directly affects the quality of temperature. In the beginning to the flowering period, it is necessary to appropriately increase the temperature, this period is usually about a month, if the heating rate is fast, then about 25 days may begin to blossom, but there will be a more serious phenomenon of falling flowers.

The above is a brief introduction to how the greenhouse manages the temperature. That's all for today's introduction. This article is for reference only. I hope it can help you all.
