Anti-season vegetable antifreeze measures

In the winter season, vegetable production in the off-season is vulnerable to low temperature and freezing. In the field management, appropriate antifreeze measures should be taken.

The first is to increase farmyard fertilizers. Warm manure such as pig cow dung or earth miscellaneous fertilizer is applied to the stem base of vegetables, and the soil temperature in the roots can be appropriately increased, and the application rate is between 1,000 and 1,500 kilograms per mu.

The second is to protect the earth. Before the soil is frozen, combining cultivators and cultivating the roots will not only loosen the soil, increase soil temperature, but also directly protect the roots of vegetables.

The third is foliar dressing. Foliar spraying 1 to 2 times 0.2% potassium dihydrogen phosphate solution, can enhance cold resistance.

The fourth is to cover the straw. Before the frost comes, the use of straw or other dry grasses or weeds on the vegetable plants will reduce frost damage.
