1. Citrus: Lightly knock off or shake off the ice and snow that hung on the tree with your hands or bamboo poles. Then, remove snow from the ground around the tree trunk and cultivate 20-30 cm of soil around the root of the tree to prevent the entire tree from freezing. For nurseries or saplings, some straw or hay can be laid on the basis of snow and covered with plastic film. It is the time of spring fertilizer. The main role of spring fertilizer is to spawn spring shoots and lay the material foundation for flowering results and high yields throughout the year. However, in the case of snow and ice cover this year, the roots and leaves have suffered various degrees of damage and it is difficult to absorb and produce nutrients. Therefore, based on the degree of frostbite trimming, different methods of fertilizer application should be adopted. For trees with heavier frostbite, foliar spray fertilizer is the main ingredient. In sunny days from 10 am to 4 pm, a 0.2%-0.4% solution of urea is sprayed once a day and 0. 1% - 0.2% potassium dihydrogen phosphate solution, continuous spraying 3-5 days. On the one hand, it can quickly supplement the trees with nutrients. On the other hand, it can add moisture to the trees and prevent them from suddenly losing water due to frost damage or sudden turning of the weather, resulting in wilting. As the trees are damaged, the concentration of spray fertilizer should be reduced as compared with normal foliar fertilizers, and it should be applied continuously. The concentration of urea is generally not more than 0.5%, and the concentration of potassium dihydrogen phosphate does not exceed 0.3%. For the lighter freezing damage, especially for fruit trees without basal fertility in the fall, base fertilizer should be applied. It is recommended that 30 to 40 kg of composted organic fertilizer be applied per citrus or 1 to 1.5 kg of high-nitrogen and phosphorus-type compound fertilizer. Citrus fertilization also pay attention to the following three points: 1. It is easy to breed pests and diseases in low-temperature and wet weather, so fertilization should be combined with pest control. 2. Fertilization should be combined with appropriate sparse fruit thinning. 3. It is necessary to increase the soil temperature and improve the ventilation of root soil by cultivating loose soil and drainage. Second, greenhouse vegetables: This is the most serious freeze damage is the eggplant vegetables, if the severe cold injury, to change the melons, cabbage and other vegetables that can be nursed and transplanted in time, you can also change the spinach, garland chrysanthemum, bok choy , radish and other short-growing vegetables. For the greenhouses, no basal fertilizer may be used, but for the open-land vegetables, 1000-3000 kg of fully-fertilized organic fertilizers and 100% of the high-nitrogen compound fertilizers will be used. 3. Wheat seedlings: The area of ​​rice crops in southern China is relatively large. The rains and snows have increased the damage and adversely affected the return of green wheat. The first task is to dig trenches and drains, so that vertical trenches, gutters, and Tiantougou facilities are provided. The trenches communicate with each other and the main river communicates. The groundwater level in the wheat field is controlled to be at least 50 cm. After the wheat seedlings grow back to normal, they are combined with cultivator loose soil. Alas, Mushi applies about 5 kilograms of urea, or 10 kilograms of ammonium sulfate. Pay attention to topdressing fertilizer can not be too much at a time, the fertilizer varieties to ammonium nitrate or nitro compound fertilizer best, ammonium sulfate, urea followed. Since it is not possible to fully irrigate and cover the soil, it is better not to use ammonium bicarbonate. For drought-ripe and wheat fields, due to the low temperature of the snow, the wheat seedlings are delayed or subjected to different degrees of frost damage. They must be combined with the cultivator to spread leeches and raise the soil temperature.
