The wintering cultivation method of garlic can effectively improve the survival rate and harvesting yield of wintering garlic during the planting period. The garlic planted by this method can be raised from 1.5 to 18,000 per acre to 4.5 to 60,000, which meets the requirements of reasonable close planting. Increased land use rate, stable wintering, no damage to seedlings, after seeding, the seedling rate reached 98%, the yield increased by 40% to 50%, and the trace element content was the same as that of the conventional method. The cultivation of garlic by wintering cultivation method is simple and easy to operate, and the production cost is low. When the garlic is screened, the sandwich small garlic can carry out the production of garlic yellow, further improve the economic benefit of planting, increase the added value of agricultural products, and have a good promotion. value. At the same time, under the premise of pouring the frozen water, the flat temperature and fertilizer is 4~5 cm of the cow dung, and the mulch is covered to keep the soil, filling the cracks and cracks, and the purpose of heat preservation and protection has been achieved. In order to enable garlic to be listed before the Spring Festival, the cold shed can be added to the planted garlic 7 to 10 days after the soil is frozen, so that the garlic is premature and the economic benefits of planting are improved. The specific management methods are as follows:

The garlic clams are watered once every 7 days, and the garlic is stopped 4 days before harvest.

After the garlic is expanded, the garlic is added with 2 to 3 kg of nitrogen fertilizer per acre in 1 to 5 days, and the potassium fertilizer is 2 to 4 kg, and water is poured every 5 to 6 days, and water is stopped 5 to 7 days before harvesting.

After the seedlings, the garlic seedlings were planted with three leaves and then poured once to promote the seedling water, and the cultivating and weeding, the soil was poured over the winter water before freezing, and the temperature and fertilizer were 9 cubic meters per mu, the average thickness was 5 cm, and the compaction was covered with plastic film. Filling the cracks and cracks has reached the goal of heat preservation and protection.

During the differentiation period of the flower buds of garlic flower buds, the spring air gradually warms up, uncovering the film and pouring it back into the green water once, and applying 3 to 4 kg of nitrogen fertilizer per mu.
