About water soluble fertilizer
What is water soluble fertilizer? Water soluble fertilizer is a new type of fertilizer that can be completely dissolved in water and developed in China in recent years. It is an industrial-grade fertilizer that is easily soluble in water such as diammonium phosphate, urea and potassium chloride. It is scientifically proportioned according to a certain proportion, and is added with boron, iron, zinc, copper, molybdenum and chelated trace elements. A fertilizer that can be completely dissolved in water combined with the new production technology can be used to complete fertilization through irrigation and drip irrigation water-saving agricultural facilities. It has the characteristics of high fertilizer efficiency, saving fertilizer, labor saving, and increasing production.
What are the classification of water-soluble fertilizer products (1) A large number of elements of water-soluble fertilizers: mainly one or more of nitrogen, phosphorus, and potassium. The nitrogen fertilizer can use organic nitrogen sources such as amide nitrogen, ammonium nitrogen, nitrate nitrogen, or amino acids. The raw materials can be urea, ammonium nitrate, potassium nitrate, ammonium chloride, amino acids, etc. The main phosphate fertilizers are orthophosphate and metaphosphate. Polyphosphate, etc., generally used in production of potassium dihydrogen phosphate, dipotassium phosphate, ammonium phosphate, phosphoric acid, and some metaphosphate and polyphosphate; Potassium is generally used potassium nitrate, potassium dihydrogen phosphate, potassium sulfate Such as raw materials.
(2) Water soluble fertilizer with medium amount: Generally refers to calcium, magnesium, boron, silicon and other ingredients. Among them, calcium fertilizers mainly use water-soluble inorganic calcium salts and chelated calcium. The raw materials for the products include calcium chloride, calcium nitrate, calcium ammonium nitrate, calcium acetate, and calcium chelated with EDTA, citric acid, amino acids, sugar alcohols and other organic substances. Magnesium mainly uses water-soluble inorganic magnesium such as magnesium chloride and magnesium sulfate; silicon mainly uses sodium silicate as a source, and since it is alkaline and easily reacts with ions of calcium, magnesium, zinc, iron, and the like to generate flocculent precipitates, it is generally used alone. .
(3) functional water-soluble fertilizer: As the name suggests has a special effect of water-soluble fertilizer. For example, plant growth regulator type water-soluble fertilizers, such water-soluble fertilizers added substances with biological growth regulating functions such as gibberellin, naphthaleneacetic acid (sodium), and fertilizer-type water-soluble fertilizers. These water-soluble fertilizers contain the necessary nutrition for plant growth. In addition to the elements, a certain number of different types of pesticides and herbicides will also be added. In addition to promoting the growth and development of crops, the occurrence of pests and weeds can also be prevented. Usually, they can be divided into weeding special fertilizers, bactericidal special fertilizers, and insecticide-specific fertilizers. In addition, water-soluble fertilizers can also be divided into amino acid water-soluble fertilizers, humic acid water-soluble fertilizers, sugar alcohol-containing water-soluble fertilizers, alginic acid water-soluble fertilizers, sea urchin water-soluble fertilizers. Some water-soluble fertilizers do have the effect of preventing and controlling diseases and insect pests, but not all water-soluble fertilizers have a significant role in controlling pests and diseases. At the same time, from another perspective, water-soluble fertilizers can directly supplement plants with the nutrients they need to grow, which will increase the plant's resistance to a certain extent, thereby reducing the probability of disease occurrence and effectively reducing the occurrence of physiological diseases.
How to use the key depends on the water
Water-soluble fertilizers have a wide range of applications. Corresponding to this, there are many ways and methods of application. In well irrigated areas, water-soluble fertilizers can be used for equipment fertilization. Water-saving agricultural facilities such as sprinkler irrigation and drip irrigation can be used in combination with fertilisers to achieve the effect of water and fertilizer integration. At the same time, it is not limited by terrain, such as slopes and depressions. As long as the irrigation system is designed properly, it can be used to directly transfer fertilizer and moisture to the roots of crops, improve the efficiency of water and fertilizer utilization, increase production efficiency, and achieve semi-automated, automated management, saving manpower, which is the best application of water-soluble fertilizers.
In the channel irrigation area, flushing can be used. The fertilizer is poured into the irrigation water at a certain proportion in the irrigation inlet. The operation is simple but the quantification is inaccurate. In the process of fertilization, the liquid fertilizer should be uniformly applied according to the amount of irrigation and irrigation time. Pour into irrigation water and master the dilution factor of fertilizer. It is generally recommended that the dilution of water-soluble fertilizer be 1000-1500 times.
In arid regions, water-soluble fertilizers can be used as spraying foliar fertilizers. Spraying foliar fertilizers can provide nutrients for crops and direct absorption and utilization of foliage. At the same time, the foliar fertilizer can also be flexibly matched with anti-drought and anti-drug reagents, fertilizer synergists, etc., in order to improve the ability of crops to resist stress and nutrient absorption. However, during the operation, pay attention to the concentration of fertilizer and spray it strictly in accordance with the instructions for use. If the concentration exceeds the limit, the blade will be damaged. Spraying will generally be diluted 500-800 times.
Want to use good nutrition to match
For a long time, the three major elements of nitrogen, phosphorus, and potassium are considered in the fertilization process of crops. However, little attention has been paid to trace elements. Basically, it depends on soil supply, and year after year causes the trace elements in the soil to be hollowed out. No longer meet the needs of crop growth, it will also affect crop growth.
Therefore, it is necessary to pay attention to soil testing results, and constantly look for short boards of nutrients in crop growth. When liquid fertilizers are used, they should be supplemented with medium and trace element fertilizers to supplement the crops in time and make up for short boards.
Want to be efficient coupled with water and fertilizer
In practice, some experts concluded: “The root is the seedling's mouth, and the water is the fat's leg.†Water plays an important and precious role in the process of fertilizer transfer. Fertilizer can only rely on water to reach the crop root and be absorbed by crops. Pay attention to water and fertilizer coupling when applying liquid fertilizers.
If the irrigation volume is too large, excessive irrigation will be formed. The fertilizer dissolved in the water will continue to move downward along with the infiltration of the irrigation water, eventually exceeding the range of absorption of the roots, and the nutrients of the fertilizer will be lost, causing waste. Too little irrigation volume not only fails to meet the crop's demand for water, but also results in excessively high concentrations of fertilizers, which accumulate on the surface of the soil and scald the roots of the crops, causing “burning seedlingsâ€.
Only moderate irrigation can meet the water and fertilizer demand of crops. At the same time, the nutrient solution is evenly distributed around the roots of the crops. It neither burns seedlings nor is lost. It also reduces the migration distance of nutrients in the soil and promotes the absorption of nutrients by crops to achieve water and fertilizer. Synchronous and efficient purpose.
