Description
Technical Field
The invention belongs to the technical field of agricultural fertilizer preparation, and particularly relates to a liquid nitrogen fertilizer for improving crop planting and a preparation method thereof.

Liquid fertilizers, also known as fluid fertilizers, include clear liquid, suspended, and slurry types. The liquid fertilizer has the following advantages: dust and smoke can not appear in the production, application and transportation, and the pollution is less; the product has no problems of moisture absorption and caking; can be mixed with pesticide, bactericide and herbicide and can be mixed uniformly; the quality is not different like the segregation of solid fertilizers in storage and transportation; the application method is various, can be sprayed on the leaf surface, can be applied along with water, can also be used for sprinkling irrigation, drip irrigation or irrigation, and has the advantages of convenient use, cost saving and quick effect. Therefore, liquid fertilizers are one of the trends in the development of the fertilizer industry in the world today. In the 90 s of the 20 th century, the liquid fertilizer consumed in the United states each year accounts for more than 38% of the total fertilizer consumption. In recent years, liquid fertilizers have been rapidly developed due to the application of foliar fertilizers and irrigation techniques, particularly drip irrigation techniques.
The liquid slow-release nitrogen fertilizer adopts an advanced polymethylene urea slow-release technology and combines American active small molecular carbon, the traditional striking root fertilizer can be replaced by spraying the liquid slow-release nitrogen fertilizer on a seedbed before rice transplanting, the striking root speed is extremely high, the seedling reviving process is almost not generated, and the spraying method is labor-saving; the fertilizer can be used on corn to replace topdressing, and can be used as spike fertilizer in the later period, and the yield increasing effect is particularly obvious when the fertilizer is used before soybean pod setting. The liquid slow-release nitrogen fertilizer is very safe for spraying rice seedlings, and because the salt index of the liquid slow-release nitrogen fertilizer product is extremely low and is within 0.5, and the urea height is up to 70, the seedling burning phenomenon can be caused by spraying after the common urea is converted into water. Therefore, the adoption of the liquid nitrogen fertilizer can greatly promote the increase of the crop yield and reduce the occurrence probability of plant diseases and insect pests.
