When the continuous rain and snow fog suddenly turn cloudy, the grass blades in the solar greenhouse will appear wilting, especially the cucumbers and zucchini with the largest leaves. The reason is that the indoor temperature and ground temperature are very low during continuous cloudy days, the root activity is weak, and the absorptive capacity is drastically reduced. After the sunny days, the light is sufficient, the temperature rises rapidly, the air humidity drops, the leaf surface water transpiration is large, and the root water absorption cannot satisfy the transpiration water above the ground. The consumption. If measures are not taken in time, the wilting leaves will not be restored and they will even die. In the sunlight greenhouse when it encounters continuous rain or snow, it can take three measures: 1. Repeatedly uncover the grasshopper. If the leaves are found to be wilting after being uncovered, they should be immediately covered with a part of it and wait until the leaves have returned to normal. Then cover them again, and then repeat until no more wilting occurs. 2. During the unrolling of grasshoppers, spray the leaves with fresh water or nutrient solution. If you use a 1% glucose solution to spray the leaves, the effect is better. If there is not enough moisture in the soil, it should be poured once per day before and after noon on sunny days, but do not flood the water to avoid cooling. On the day before spraying and watering, part or most of the flowers and young fruits on the plants can be removed, which has a significant effect on promoting the recovery of the crops, and is particularly effective on cucumbers with flower tops. 3. Before the onset of cloudy days, use medical vitamins B1, B6, and amide to mix into 800 times liquid, and press 5000 ml of solution to add a line of medical penicillin (which can kill freezing point bacteria). Plant tolerance to low temperature.
