Precautionary measures before the arrival of severe weather 1 Lower the management temperature, implement low-temperature hardening, improve the cold resistance of vegetables, and 2 spray antifreeze chemicals to improve the cold resistance of vegetables. When the cooling rate is relatively large, medicinal vitamins B1, B6, amide, penicillin and other agents can be sprayed to spray the plants. Each 5 kg aqueous solution contains 2 mg of vitamin B1, B6 and amide, and 1 penicillin. When the cooling rate is small, you can spray 1 nutrient foliar fertilizer. 3 Wipe the film to increase the light transmittance. 4 Check the greenhouse facilities to ensure the insulation performance of the greenhouse. 5 Prepare warm items such as straws, paper quilts, saggers, etc., and warm items such as stoves, coal-fired or mobile stoves.
Corresponding measures for the arrival of severe weather 1 Multi-layer coverage, pay attention to insulation. 2 In case of strong winds, it is necessary to compress the shelter. 31 Lianyungang’s weather spreads. If the temperature is not very low, you should open your eyes every day and make proper ventilation. Can be covered as early as possible cover 4 rain and snow weather, sheds and snow. 5 When the temperature is too low, artificial warming is applied. When the temperature in the greenhouse falls to the minimum temperature required by the vegetables, warming measures are taken, such as adding small and medium arch sheds, covering the shed, increasing the temperature of the fire, etc. The temperature is too fast and too high. 6 Thinning and fruit thinning reduce nutrient consumption. If there is a long period of low-temperature weather, the plants with weaker growth or more results will be harvested in time, and appropriate fruit thinning and thinning will occur. 7 When the disease occurs, timely prevention and treatment. In case of severe weather, it is easy to cause disease infestation and occurrence, and it can be prevented and treated with aerosols in time.
Management measures after the severe weather 1 See the light slowly and avoid flashing seedlings. When the shade is clear after the shade, one method can be used to remove one to three grasshoppers, so that the vegetables can gradually see the light and avoid the seedlings hitting the seedlings. So repeated several times or a few days, the number of uncovered oysters from a little to as much as normal until the growth of vegetables. Rollers are used to roll grasshoppers to the middle of the shed. 2 foliar spray fertilizer, nutritional supplements. 3 In the event of freezing injury, promptly remedy. Cut away dead branches and artificially spray water, manage with low temperature and less light, and gradually increase light and temperature. 4 Strengthen management and promote Miao and rejuvenation.

Insect net greenhouse also known as plant and vegetables greenhouse net. Used for prevent the insect fly into the greenhouse during the plant growing, and cover the plants. Key off the approaches that the pests (adult insect) breeding. Effective control of the spread of all kinds of harmful pests spread, such as Cabbage caterpillar, diamondback moth, aphids, flea beetles, Sweet agnates, American leaf miner, literal etc and prevent the harmful of virus spread. Significantly reduced the use of chemical pesticides, so that the planting vegetables good-quality and health.
