The temperature in our province is low in winter, and the vegetable growing period encounters severe weather such as low temperature, cold current and frost, which often leads to plant death and disease death, which often brings greater economic losses to growers. Here are some more practical vegetable antifreeze method: 1. Choose good varieties and cultivate more soil. When planting vegetables in winter, you should choose varieties with stronger cold tolerance, and try to plant them on plots that are more sunny and sheltered from wind. At the same time, combining cultivating and cultivating soil next to the roots can loosen the soil, increase soil temperature, protect the root system, and enhance root vigor. The cultivating soil must be carried out before the soil is frozen, and the depth of cultivating should be 7-10 cm. 2. Apply organic fertilizer to strengthen coverage. Before frost, use pig, cow dung or soil manure and other heat-preserving farmyard manure, and cultivating it at the roots of vegetable trees can increase the soil temperature by 2 to 3 degrees. At the same time, spray plant nutrient solution to improve the cold resistance of plants. 3. Clean ditch and drain, control nitrogen and spread ash. Rainy weather, high humidity in the field, and insufficient sunlight, are unfavorable to the growth and development of vegetables. Clean the ditch and drain water in time to ensure that the ditch and ditch field are unblocked so that the frozen water can be removed in time, which is good for preventing freezing and cold of vegetables and preventing waterlogging and moisture in the coming spring. . Before the low temperature comes, sprinkle a thin layer of plant ash on the vegetables and between the rows of vegetable plots, which can prevent cold and freeze and increase nutrients. Nitrogen fertilizers should not be applied during vegetable seedlings to avoid young plants and poor cold resistance. The top dressing should be done early to promote healthy vegetable seedlings. Before the low temperature, do not apply quick-acting nitrogen fertilizers. It is advisable to apply phosphorus and potassium fertilizer once to enhance the vegetable’s growth. Cold resistance. 4. When the temperature is lowest in the early morning, some candles can be lit in the greenhouse to increase the temperature. Although this measure does not have a great impact on the indoor temperature, it can *** reduce the temperature-loving crops (leaf vegetables, melons) at critical times. In addition, lighting candles can also supplement part of the light. Disclaimer: Some articles on this website are transferred from the Internet.
