The Latest Temperature Management Methods for Greenhouse Cherries
The cherry is a fruit with a relatively high market price, but there is still very large market demand for it in our country. At present, cherry cultivation methods are generally based on greenhouse planting, and when we grow greenhouse cherries, management work is very important. Temperature management in particular, so how should greenhouse cherries be managed for temperature? Today the editor will give everyone a brief introduction, so let's take a look below!
1. Temperature during the flowering period
When managing the temperature for cherry growth, we should manage it according to the changes in the cherry's growth stages. During the flowering period, a relatively stable temperature must be maintained, and the temperature must not be too high or too low. The minimum temperature should be kept at around 10 degrees, and special attention should be paid to the temperature at night. If the temperature is too low, heating must be applied in time. Then, if sunny weather occurs, attention should also be paid to doing a good job of ventilation and cooling, and a thermometer should be properly equipped inside the shed. Observe temperature changes frequently, and when the temperature is too high, it must be cooled in time. 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 the fruit-setting period
As just mentioned, we should appropriately adjust the temperature as the cherry's growth stages change. After the cherry enters the fruit-setting period and begins to set fruit, the temperature should be kept at around 18 degrees. Then, in the early stage of young fruit development, and after the flowers fall and the young fruit begins to swell, the temperature should gradually rise to around 22 degrees. The temperature must not exceed 30 degrees at most, otherwise it will have a very large impact on cherry growth. And the day-night temperature difference should also be maintained well, with the nighttime temperature controlled at around 8 degrees, and not exceeding 10 degrees at most.
3. Temperature during the swelling period
After the cherry sets fruit, as time goes on, it will gradually enter the fruit swelling period. During the cherry fruit swelling period, the temperature must absolutely not be too high, otherwise it will not only affect fruit swelling and lower fruit quality, but also cause phenomena such as fruit drop. During the period from fruit coloring all the way to fruit maturity, the temperature should be controlled at around 23-24 degrees. The day-night temperature difference should be maintained at around 10 degrees, and a suitable temperature is very favorable for fruit coloring and swelling.
⟦NL>4. Temperature regulation
The temperature and humidity regulation of greenhouse cherries can be adjusted through methods such as ventilation openings or removing the film. In the early stage of cherry growth, temperature regulation directly affects the cherry yield, while the temperature in the later stage directly affects the quality. When starting to raise the temperature until the flowering period, the temperature should be appropriately increased. This period is generally about one month. If the temperature rises quickly, then flowering may begin in about 25 days, but there will be a relatively serious flower drop phenomenon.
The above is a brief introduction to how to manage temperature in greenhouses. That is all for today's introduction. This article is for reference only, and I hope it can help everyone!
