How to manage vegetables during typhoon weather? Latest technical key points
Recently, the coastal provinces of our country have suffered very severe typhoon weather. It has had a great impact on people's lives, and there may even be some casualties. It has also caused serious harm to people's economy. Especially for some vegetable growers, it is hard for people to guarantee their own safety, let alone vegetable crops. So how should vegetables be managed under typhoon weather? Let's take a look together with the editor below!
1. Preventive measures
Reinforcement and protection
First, we must pay attention to weather changes. Before a typhoon arrives, there are generally related news and warnings issued. When we learn that a typhoon is coming, the first thing we must do well is reinforcement and protection, especially for climbing and tall-stalk crops such as cucurbits and beans. Seedling beds should be protected against wind and rain. If seedlings have not yet emerged, then films should be covered to prevent rainwater from washing away the soil and causing failure to emerge. If the typhoon level is greater than 10, then the greenhouse film should be removed in advance to avoid damage to greenhouse facilities. If the wind is not strong, then the greenhouse should be reinforced to prevent collapse caused by wind.
Other precautions
Vegetable planting is most vulnerable to waterlogging, and typhoon weather usually brings rainstorms. Therefore, we should also pay attention to doing a good job in flood prevention and waterlogging prevention for vegetable greenhouses, check the ditches around the greenhouses, do a good job in dredging the canals, ensure the canals are unobstructed with no blockages, and reduce the hidden danger of water accumulation in vegetable fields. Then, for some vegetables that can be harvested appropriately earlier, it is best to harvest them in advance. This can effectively reduce losses, avoid too many damaged vegetables, and even prevent total crop failure.
2. Measures for restoring production after a typhoon
Vegetable management
After the typhoon and rainstorm, drainage work should be done well, the accumulated water in the field should be drained promptly, and plant residues should be removed. For vegetables that still have use value, wash off the sand and soil, and then stand up the plants that fell over during the typhoon. Then carry out intertillage on the soil to avoid soil hardening, improve soil permeability, and promote the root system to resume growth as soon as possible. Enhance the soil's ability to absorb nutrients and water. Then combine intertillage with earthing up. After a typhoon, field humidity is relatively high, and plants are susceptible to damage from pathogens, so attention should also be paid to doing a good job in pest and disease control.
Rush harvest for market
For vegetables in the field that can be harvested, rush harvesting for market should be carried out. Then plow on sunny days, and use the method of sowing in batches to plant some fast-growing vegetables suitable for growing in the current season. For example, water spinach, baby bok choy, etc., and then use liquid foliar fertilizer, potassium dihydrogen phosphate, etc. for extra-root topdressing. Promote the rapid restoration of vitality, and appropriately add brassinolide to promote vegetable growth and enhance plant stress resistance.
