How to properly manage greenhouse cherries when bad weather hits

Greenhouse cherries

    In recent years, because greenhouse cherries bring high returns, the growing area has expanded rapidly. When bad weather strikes, a single case of poor management can cause huge losses for growers. During management, the following points should be noted:

    1. Cold, overcast weather. In winter or early spring, when there is sustained low temperature or a cold wave, straw mats and other covers should be uncovered a little later than usual. After uncovering the mats, watch the changes in greenhouse temperature. If the greenhouse temperature changes only slightly, uncover and cover again as you go, so that the greenhouse temperature rises, and cover everything again before 2 p.m. To raise the nighttime temperature inside the greenhouse, you can appropriately increase the thickness of the covers, or extend the time the stove is burning. Remember never to leave the covers off all day, or for several days in a row, during cold, overcast weather.

    2. Windy weather. During the day, secure the transparent covers so they are not blown away by the wind, and at night weigh down the straw mats properly. Once covers are blown off by the wind, the cherries are very likely to suffer frozen blossoms or frozen fruit, causing a reduction in yield.

    3. Cloudy weather around midday. When the light is fairly strong around midday, the greenhouse temperature changes quickly. If clouds appear in the sky, keep watching the greenhouse temperature at all times: when clouds block the sun and the greenhouse temperature drops, close the vents properly; when the clouds pass and the sun comes out, the greenhouse temperature will rise quickly again, so open the vents promptly to prevent scorching, especially after fruit set.

⟧    4. Rain and snow weather. When rain or snow falls during the day, cover the straw mats properly and add a rain- and snow-proof film on top of them; once the rain or snow stops, immediately clear away the accumulated rain and snow. When snow falls at night, sweep the snow away promptly the next morning after it stops, keep the covers dry, and remove the covers so the trees get light. After continuous snowfall, when the sky suddenly clears, pay attention to the changes in the cherry trees when you remove the covers again, and check whether the new leaves are wilting. If wilting is found, immediately cover them again with straw mats, and uncover them again once they recover. Repeat this for 2-3 days, and then you can return to normal management.
