Avoid dry freezing: After winter irrigation, soil water content will increase, heat capacity and thermal conductivity will increase accordingly, day and night temperature will decrease, and near-surface temperature will be moderated, which will reduce wheat dry freezing damage.
Water storage and storage: After winter irrigation, water will exist in the soil in a crystalline state, will not be lost due to factors such as gravity, and the mineral nutrients dissolved in the soil solution will not be leached and lost, and can be well preserved in the soil. Among them, it functions as a water storage tank.
Prevention of spring drought: The northern wheat region of China has a long winter and less snowfall. In spring, there is also a general drought in the spring. After winter irrigation, it can not only meet the winter physiological activities of wheat, but also provide sufficient water for the smooth and early return of wheat in spring.
Improve soil structure: After three seasons of soil cultivation, especially unreasonable soil cultivation, the soil compaction and tillage layer will be hard and the block structure will increase. After winter irrigation, the soil will be affected by the interaction of freezing and thawing. The structure of the granulation, the soil rhizosphere environment of wheat is improved. Premature wintering of wheat can lead to excessive growth of wheat seedlings and no freezing resistance; watering too late, soil freezing, is unfavorable for wheat root development and safe wintering.

The main differences between powder,premixed agent, granule are as follows:
Veterinary Soluble Powder: means a dry powder preparation made of one or more drugs by grinding and evenly mixing, with or without dressing.
Premix: refers to one or more drugs, and a suitable substrate evenly mixed to make a powder or granular preparation.
As a dosage form of feed drug additive, it is specially used for mixed feeding.
Powder powder, that is, powder, and premixed agent, the main differences of granules are as follows:
1.the production method is different
1.powder: medicine or with appropriate auxiliary materials by grinding, evenly mixed dry powder preparation.
2.Veterianary premix: powder or granular preparation made by evenly mixing the drug with an appropriate substrate.
3.granules: raw materials and appropriate excipients mixed into a certain particle size of dry granular preparation.
2.different characteristics
1. Dispersing agent: compared with other solid dosage forms, dispersing agent is easy to disperse, dissolves quickly, absorbs quickly and takes effect quickly; The preparation process is simple, the dosage is easy to control, and it is easy for infants to take.
2.Premix for animal: Premix used in the matrix including carrier, diluent, etc. The substrate should be stable, with good fluidity, and easy to mix with drugs and feed.
3. Granule: the dispersion, adhesion, agglomeration and hygroscopicity of granule are lower than that of granule; The separation of various components in granule is avoided because of the adhesive used to make granule after mixing. Convenient storage and transportation; Particles can change their function by coating.
