According to the forecast of the Qinghai Provincial Meteorological Observatory, in the past two days, most of the province has about 7 west winds, and the gusts can reach 9 levels, the temperature drops by 6-8 degrees, and the local area can reach 8-10 degrees. The air blow will have a destructive effect on all greenhouse facilities and equipment. In the process of cooling, except for the facility agriculture of Xunhua, Minhe and the two places, the rest of the agricultural area is at an unsuitable level. It is recommended that all users do antifreeze and windproof preparation work.
Agricultural production advice:
1. Before the onset of cooling, apply grass ash or decomposed fine organic fertilizer to increase the ground temperature.
2. Increase the cover of straw curtains and quilts in time to prevent freezing and prevent low temperature from invading greenhouse crops.
3. During the cooling period of the facility agriculture, according to the weather conditions, the curtains should be appropriately postponed in the morning, and the curtains should be covered in advance in the afternoon to prevent the loss caused by low temperature.
4. Reinforce existing greenhouses or greenhouses, repair membranes and film strips in time to prevent damage to greenhouses or greenhouses by windy weather.
5. After the weather has cooled down, strengthen the field management, actively pursue the foliar fertilizer, and promote the recovery and growth of the plants.
