The growth rate of various types of vegetables in winter has become slow and prone to frost damage. Take the following five measures: 1. Use cold-tolerant vegetable varieties. For vegetables that are not tolerant to cold and prone to freezing, they should be planted on plots that are relatively sunny and sheltered from the wind. 2, dense planting. The dense planting in winter is conducive to the increase of the temperature of the microclimate in the field. At the same time, the dense planting can greatly reduce the invasion of the cold wind and can reduce the wind speed. Therefore, the heat loss of the soil is slower, which is conducive to delaying the temperature drop of the ground and the plant cluster. 3, appropriate deep planting. The roots of the vegetable seedlings (stem and root junctions) are very “delicious†and easily freeze and cause the whole plant to die. When properly planted, the root neck can be protected by the soil. 4, rational fertilization. After vegetable planting in November, the top manure was appropriately applied to make it grow. In December, nitrogen fertilizer was controlled because the growth was too prosperous and there were more "free waters" in the cells. The seedlings were susceptible to freezing injury. 5, timely harvest. In the cold before the invasion of the cold, the vegetables may be looted frozen, stored indoors, listed in batches. If the cauliflower is uprooted, it can be stored in the room for two weeks and the flower bulb can continue to grow.
