According to local experience, the application of brown sugar decaurea deca superphosphate in ponds where fish and shrimp are farmed can play a role in fattening water, reduce moss, and promote the growth of fish and shrimp. Foliar spray can also be carried out using brown sugar decaurea superphosphate solution to supplement nutrition and promote high quality and high yield. All localities can choose according to their actual situation, and implement them on the basis of personal and small-scale experiments, and do not copy and paste.
The brown sugar urea calcium superphosphate solution is able to fertilize water and act as a principle of foliar fertilizer
Brown sugar is a primary sugar processed from sugarcane, not edible sugar, it contains about 95% of sucrose, but also contains fructose, glucose a variety of monosaccharides and polysaccharide energy substances, carbohydrates, cellulose, riboflavin, carotene and other vitamins, malic acid, niacin, folic acid and other amino acids, antioxidant substances, phosphorus, potassium, calcium, iron, manganese, zinc, chromium and other a large number of elements, medium elements and trace elements. Sugars, amino acids and trace elements can not only increase the organic matter and mineral content of the pond to achieve the purpose of fertilizer water, but also promote the reproduction of microorganisms such as aquatic plants and algae, increase the food source of fish and shrimp, and promote the production of aquatic products.
Brown sugar is used for foliar fertilization, which can supplement the glucose, fructose, various amino acids and trace elements needed by plants, and is directly absorbed by the foliar surface of crops to promote vegetative growth and fruit expansion.
The active ingredients of calcium superphosphate fertilizer are mainly monocalcium phosphate, dicalcium phosphate and a small amount of phosphoric acid, but also contains anhydrous calcium phosphate, most of which are easily soluble in water, calcium superphosphate leaching solution is applied to the pond, which can increase the phosphorus concentration and free calcium element of the aqueous solution, and play a role in fertilizing water. Calcium superphosphate leaching solution can also be sprayed foliarly to supplement phosphorus, calcium and sulfur.
Urea is the nitrogen fertilizer with the highest nitrogen content, often used as a foliar fertilizer to supplement nitrogen elements, to promote the normal growth of seedlings and fruit expansion, urea can also be sprinkled in ponds for fertilizer.
In what ways can the brown sugar urea superphosphate solution be used?
Farming of crayfish is preceded by fertilization. Before stocking crayfish, according to the weight of brown sugar, urea and calcium superphosphate in the ratio of 1.5 to 2.5: 0.8 to 1.2: 1, stir, sprinkle in the pond, every 10 acres of land to sprinkle brown sugar urea calcium superphosphate solution according to the amount of calcium superphosphate 1.8-2.5 kg of calcium superphosphate is appropriate. Sprinkle at 11 to 12 o'clock in the morning, and put in the shrimp fry at 15-16 o'clock in the afternoon, the fertilizer water effect is very good, which can meet the basic needs of the crayfish for the environment.
Brown sugar urea calcium superphosphate solution anti-moss. When the crayfish hatchlings begin to operate normally, the brown sugar urea superphosphate solution is sprayed or sprinkled on the surface of the entire breeding pond or rice field, which helps the reproduction of algae such as Elekella, promotes the reproduction of beneficial bacteria such as amino acid bacteria and yeasts, and meets the needs of the normal growth of shrimp fry. Each mu of water surface is prepared according to the ratio of 2 kg of calcium superphosphate.
Foliar spraying of brown sugar urea calcium superphosphate solution from the seedling stage to the expansion stage of melon fruit. The configuration ratio is 1% brown sugar, 0.2% urea, 10% calcium superphosphate, and 0.3% brassicalin endolipid, which is conducive to the high yield of watermelon.
Topdressing is carried out with brown sugar urea calcium superphosphate at the seedling stage of celery. Each mu of land is applied with 0.5 kg of brown sugar, 10 kg of urea, 3 kg of calcium superphosphate, and 2 kg of potassium chlorate, which can be applied at the root or sprayed after adding 500 times water.
During the harvest period of celery, foliar spraying of brown sugar potassium dihydrogen phosphate solution and foliar spraying can improve the quality of celery and prolong the storage period of celery. Foliar spraying was carried out using 100 g of potassium dihydrogen phosphate and 200 g of brown sugar per acre, diluted 500 times.
Tips:
1. When spraying fertilizer on the foliar surface of crops, it is necessary to strictly control the proportion of brown sugar used, and it should not be excessive.
2. Brown sugar urea superphosphate calcium solution is widely used, suitable for foliar spraying of various crops, but it needs to be selected according to the crop growth period, external temperature, etc., and applied in a large area on the basis of experiments.
3. Foliar spraying of urea needs to pay attention to the content of diurea, unqualified urea will produce leaf burning phenomenon.
4. After the foliar spray containing brown sugar is easy, it will increase the number of aphids, ants and other pests that like sweetness, and insecticides can be added appropriately to prevent the flooding of pests.
