In winter, part of the soil in winter is idle, old trees depend on it, and soil and grass cover is a common phenomenon. As the saying goes, "early winter money is better than plowing the field." Winter plough can improve soil physical and chemical properties. After the soil is ploughed, after a long period of winter drying and freezing, it can eliminate deadlocked blocks, ripen raw soil, promote loose soil, loose structure, facilitate soil permeability, promote aerobic activity, eliminate ferrous ions, etc. Toxic substances, and the insoluble nitrogen, phosphorus, potassium, etc., in the soil are converted into easily soluble substances for release in the second year and are absorbed and utilized by crops. In winter plowing, some pests that are good at overwintering in the surface layer, such as sclerotinia sclerotia and ground tiger, can also be buried in the bottom layer. At the same time, a group of insects that need to overwinter at the base of rice plants can be plowed out to destroy their overwintering sites. . Winter ploughing will also expose the roots of most weeds to the soil surface, causing the weeds to suffer from sunlight, freezing and dead. In order to make significant winter plowing effect, plowing time should be good early and the depth should be appropriate. Generally, seven pounds or so of paddy fields should be plowed, and dry land should be up and down. Plow only and do not break flat. There are two methods of dry tillage and hydroponic tillage. Hydroponics means that the winter foam will help the plowshares in the next year, make water easy to use, and save labor; dry farming means that the winter dryness will benefit soil improvement. Both have their advantages and disadvantages, and they should be determined as appropriate. In winter plowing, it can be combined with mixed soil, clay mixed with sand and sand mixed with mud. If we apply fertilizers or manure and animal fertilizers on infertile land, then winter plowing will be the icing on the cake.
