It is winter now, and there are frequent low-temperature rains and snow. After strong cooling and snowfall, how to strengthen field soil and fertilizer management to recover losses?
Soil and fertilizer management reduces the impact of freezing damage
For crops suffering from freezing damage, you can apply super-large amounts of potassium dihydrogen phosphate, spray plant growth nutrient solutions, and use organic water-soluble fertilizers and other products and technologies to improve crop resistance and resistance, and lay a solid foundation for the restoration of growth. In addition, fertilizer-deficient plots should be topdressed with quick-acting nitrogen fertilizers as soon as possible according to the growth of crops, and appropriate amounts of phosphorus and potassium fertilizers should be applied to promote crops to resume growth as soon as possible.
Supplement nutrition to enhance crop resistance
Winter wheat has strong vitality. After freezing damage, apply quick-acting nitrogen fertilizer immediately, apply 5 to 7.5 kg of urea per acre, combine watering, cultivating soil loosening and soil moisture to remedy, and do a good job of foliar fertilization and pest control in time.
In order to promote the growth of branches, rapeseed generally apply 5-7 kg of urea, 3-4 kg of potassium chloride or spray 0.2% potassium dihydrogen phosphate solution, or apply a compound fertilizer with higher nutrient content. After plucking the stalks, fertilize appropriately according to the situation, and topdressing 5-7 kg of urea per mu to promote the growth of branches. In addition, about 50 kg of 0.1% to 0.2% boron fertilizer solution is sprayed on each mu of foliage to promote flower bud differentiation.
Facility vegetables For unharmed or less affected vegetables, spray 0.2% potassium dihydrogen phosphate solution 2 to 3 times as appropriate; spray 0.3% urea solution 2 to 3 times for nitrogen-deficient plants. Even if nitrogen fertilizer is applied, cover the soil after application to avoid ammonia volatilization and burning seedlings under closed conditions.

Cosmetics are compound mixtures made of various raw materials through reasonable deployment and processing. Cosmetics have a wide variety of raw materials with different properties. According to the raw material properties and uses of cosmetics, it can be roughly divided into two categories: matrix raw materials and auxiliary raw materials.
The former is a kind of main raw material of cosmetics, which occupies a large proportion in cosmetic formulations and plays a major functional role in cosmetics. The latter is responsible for shaping, stabilizing or imparting color, fragrance and other properties to cosmetics, which are not used in cosmetic formulations, but are extremely important. Cosmetics are chemical mixtures made of natural, synthetic or extracted substances with different functions as raw materials and processed through production procedures such as heating, stirring and emulsification.
