In spring, the temperature varies and the vegetables in the shed are often faced with strong cooling, causing various degrees of cold damage to the vegetables. These two methods solve the problem: 1. Temporarily increase insulation measures. In a fair interposition of bamboo arches, covering with a layer of plastic film to form a shed in the shed mode, the temperature of the vegetables in the small arch shelter can be increased by 2°C to 3°C. 2. Drug control. Can be divided into two methods: First, listen to the weather forecast in a timely manner, that there is a message to cool the wind, spray on the vegetables in advance Yunda 120; the second is to spray again on the vegetable before the cooling sugar and potassium liquid (0.3% of brown sugar Mix with 0.3% potassium dihydrogen phosphate). Spraying clear water at 10°C to 15°C on vegetables in the early morning after frost damage can also reduce the occurrence of frost damage. Do not warm up the fuel in the shed, so it is very easy to make the vegetables smoked.
