During the winter and spring seasons, greenhouses often suffer from severe weather such as cold currents, continuous yin, rain and snow, and high winds. Corresponding management measures should be taken in time to reduce losses.
First, snowfall management measures encountered snowfall, it is necessary to cover a layer of mane hair, and then cover a layer of rice straw, snow stopped immediately remove the snow, to prevent the melting of snow, to ensure that the cover is dry, in order to facilitate insulation. When the weather began to clear, slowly remove the cover to facilitate penetration into the sun. If the weather is suddenly clear after continuous snowfall, it is even more important that all coverings be removed, and that they should be gradually removed to prevent "flashings." After the exposing, we should pay attention to observe crop changes. When wilting occurs, we must immediately cover the grass weeds. After the recovery of the seedlings, remove the grass weeds. This repeated two or three days, and then transferred to normal management.
Second, cold weather days management measures in the winter or early spring often cold invasion, in order to avoid the occurrence of frost damage, should be based on the weather forecast, should do a good job in cold work. According to observations, the eggplant's temperature dropped to 5°C, tomatoes dropped to 10°C, and peppers and cucumbers dropped to 12°C for a long time and prone to frost damage. When the cold current comes, you must plug the vents and thicken the cover. If it is still not possible to control the temperature drop, hot air, electric heating lines, and fire pit coal stoves should be used for heating to prevent smoke damage. When the cold current lasts for a long time, the covering shall be removed before and after noon, and the temperature change shall be carefully observed after the exposing. If the temperature drops, it shall be immediately covered. If the temperature rises, it shall be covered again. After two o'clock in the afternoon, the cover shall be kept warm.
Third, the windy days management measures before the arrival of the winds, the roof, the plastic film covering the shed in front of the shed firmly at night to pressure the grass to prevent wind blown off. Since mid-February, the weather has gradually warmed up, and there have been more windy days, and the temperature of the shed has risen rapidly. Therefore, in the event of strong winds, attention should be paid to preventing the high-temperature hazards before and after noon. During the day, it is not advisable to block the vents, and do not let the strong wind directly blow in. You can change the vents to prevent heat and wind damage.
Fourth, the long-term haze sunny management measures to clear the first sunny days to keep up with the management, in addition to using the cover to adjust the temperature and light, but also immediately spray foliar fertilizer to supplement crop nutrition, enhance plant resistance , resilience, and promote growth and development. The demand for nitrogen, phosphorus, and potassium in melons and solanaceous vegetables is more balanced in a year, and three-element compound fertilizer, sprayed treasure and photosynthetic micronutrients should be sprayed. Leaf vegetables need more nitrogen in their lifetime, spraying urea, ammonium sulfate, etc., and adding appropriate amount of gibberellin. The root vegetables need more phosphorus and potassium fertilizers in their lifetime. It is better to spray potassium dihydrogen phosphate, potassium sulfate and superphosphate. Plant Power 2003 fertilizer, suitable for spraying a variety of crops, significant increase in production, and does not pollute the environment, it is worth promoting. 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.
