Agricultural practices have shown that the use of wax fertilizers mainly for manures containing more phosphorus and potassium for overwintering crops such as wheat, rapeseed, green manure, and ramie can generally increase the ground temperature by 2°C to 3°C and can increase the potassium content of plant cells. Enhance the water holding capacity of the cells, so that the plants are not easy to freeze at low temperatures, so as to play the role of insulation and cold. At the same time, the concentration of salt in the soil solution can be increased, and the degree of damage to the crop root system can be reduced. In addition, the wax fertilizer "Winter Shi Chun" can effectively promote the growth and development in the spring, and the overwintering crops in spring will enter an important period of vegetative growth and reproductive growth. This will require absorption of more nitrogen and potassium nutrients. The wax fertilizer can ensure this period. The supply of phosphorus and potassium nutrients promotes the increase of flower bud differentiation and effective branching (effective panicles), thereby increasing yield. How to improve the application effect of winter crop wax fertilizer? In summing up local experiences, the key to mastering “three observations and two attentions†is the key.
Look at the fertility of the soil to apply fertilizer to overwintering crops in accordance with local conditions. Generally, the plots with high fertility and sufficient fertility can be applied with little or no fertilization. For plots with low fertility, low base fertilizer, or plots without base fertilizer, additional fertilization is required. Phosphorus and Potassium Fertilizers; Organic fertilizers are applied to plots of mono-chemical fertilizers that are used year-round. Do not blindly abuse, or easily lead to spring crops grow out of discipline, late lodging, greed, late maturity and lead to production and other adverse consequences. In addition, the application of a small amount of sand fertilizer to sandy soil, to prevent loss of fertilizer leaching.
Looking at the growth trend of seedlings depends on the growth of the seedlings and fertilizer requirements of overwintering crops. In general, dark-green long-green seedlings should not be applied to wax fertilizer. Green-green strong seedlings should be applied with little or no wax, and leafy yellow-green or thin-leaved red seedlings should be re-fertilized.
See crop species application of wax fertilizer depends on the crop. 1. The application of rapeseed wax fertilizer: The manure and phosphorus fertilizers should be mixed and rotted. The 1500 kilograms per acre should be applied between the rows of rapeseed, combined with earthworms, and applied from late December to early January of the following year. Early maturing rape varieties should be applied earlier than late mature rape varieties due to early spring development. 2. The application of wheat wax fertilizer: should be applied in the middle and late December is appropriate, and strong seedlings should be applied more soil miscellaneous fertilizer, and weak seedlings and late-maturing wheat should be mixed in soil miscellaneous fertilizer appropriate phosphorus fertilizer. In general, about 2,500 kg of fertilizer is applied or spread per acre. 3. The application of green fat wax fertilizer: 150-250 kg of ash or a layer of thin pigs, cattle pen manure applied per acre. 4. The application of castor wax fertilizer: the amount of fertilizer should account for about 50% of the annual fertilization amount, about 4,000 kilograms of soil miscellaneous fertilizer per acre and about 2000 kilograms of pig, cow pen manure.
Pay attention to the choice of clear weather to improve the effect of applying wax fertilizer on overwintering crops, generally should pay attention to select the "snow after frost" fine weather. Usually the temperature is lower, then the application of delayed manure, compost, pond mud, ash or manure urine. When the temperature is high, grab the easily decomposable urea, ammonium chloride, ammonium bicarbonate and other fertilizers. Under low temperature conditions, ammonium bicarbonate evaporates less and can be quickly absorbed and utilized by overwintering crops when applied to soil. At the same time, the application of ammonium bicarbonate is more economical than urea. The topdressing of ammonium bicarbonate is 25-30 kg per mu for wheat and rape, but precautions must be taken when top-dressing ammonium bicarbonate to prevent burns.
Pay attention to the proper mix of fertilizers. Apply wax fertilizers and also pay attention to the selection of fertilizer types according to different crops and seedlings. Such as decomposing pig dung, human excreta, fermented pond mud, river mud, old brick soil, fire and earth ash, cake fat, etc. are all high-quality organic fertilizers. For thin and thin seedlings, human feces and urine plus nitrogen fertilizers are mainly used. , To promote seedling thick; strong seedlings should be pond mud, soil miscellaneous fertilizer based. If the application of cake fat, 40 ~ 50 kg per acre is appropriate. Organic fertilizers used as wax fertilizers should be concentrated in the roots to prevent excessive concentrations of fertilizers around the roots of the crops during the drought, resulting in reverse osmosis and physiological water loss, resulting in overwintering crops. If a drought occurs after the application of wax fertilizer, it should be combined with water drought, water to adjust fertilizer, improve fertilizer utilization.

Vitamins:
Vitamin A: Retinol. Carotene compounds responsible for transmitting light sensation in the retina of the eye. Deficiency leads to night blindness.
Beta carotene: An antioxidant which protects cells against oxidation damage that can lead to cancer. Beta carotene is converted, as needed, to vitamin A. Food sources of beta carotene include vegetables such as carrots, sweet potatoes, spinach and other leafy green vegetables; and fruit such as cantaloupes and apricots. Excessive carotene in the diet can temporarily yellow the skin, a condition called carotenemia, commonly seen in infants fed largely mushed carrots.
Vitamin B1: Thiamin, acts as a coenzyme in body metabolism. Deficiency leads to beriberi, a disease of the heart and nervous system.
Vitamin B2: Riboflavin, essential for the reactions of coenzymes. Deficiency causes inflammation of the lining of the mouth and skin.
Vitamin B3: Niacin, an essential part of coenzymes of body metabolism. Deficiency causes inflammation of the skin, vagina, rectum and mouth, as well as mental slowing.
Vitamin B6: Pyridoxine, a cofactor for enzymes. Deficiency leads to inflammation of the skin and mouth, nausea, vomiting, dizziness , weakness and anemia.
Folate (folic acid): Folic acid is an important factor in nucleic acid synthesis (the genetic material). Folate deficiency leads to megaloblastic anemia.
Vitamin B12: An essential factor in nucleic acid synthesis (the genetic material of all cells). Deficiency leads to megaloblastic anemia, as can be seen in pernicious anemia.
Vitamin C: Ascorbic acid, important in the synthesis of collagen, the framework protein for tissues of the body. Deficiency leads to scurvy, characterized by fragile capillaries, poor wound healing, and bone deformity in children.
Vitamin D: A steroid vitamin which promotes absorption and metabolism of calcium and phosphorus. Under normal conditions of sunlight exposure, no dietary supplementation is necessary because sunlight promotes adequate vitamin D synthesis in the skin. Deficiency can lead to osteomalacia in adults and bone deformity (rickets) in children.
Vitamin E: Deficiency can lead to anemia.
Vitamin K: An essential factor in the formation of blood clotting factors. Deficiency can lead to abnormal bleeding.
Nutritions:
For the treatment of nutritional disease, any of the nutrient-related diseases and conditions that cause illness in humans. They may include deficiencies or excesses in the diet, obesity and eating disorders, and chronic diseases such as cardiovascular disease, hypertension, cancer, and diabetes mellitus. Nutritional diseases also include developmental abnormalities that can be prevented by diet, hereditary metabolic disorders that respond to dietary treatment, the interaction of foods and nutrients with drugs, food allergies and intolerances, and potential hazards in the food supply. All of these categories are described in this article. For a discussion of essential nutrients, dietary recommendations, and human nutritional needs and concerns throughout the life cycle, see nutrition, human.
