How to properly choose and use commercial organic fertilizer

This period is the concentration period for the greenhouses to change the garden. Many vegetable farmers call to ask the author how to use fertilizer in the summer, especially how to choose organic fertilizer, how to use the commodity organic fertilizer correctly. Here we will discuss how to correctly understand and use commercial organic fertilizer.
The organic fertilizers that we usually refer to are organic fertilizers that are produced in accordance with industry standards and processed in a multi-process such as high-quality organic matter (soybean meal, animal manure, crop straw, etc.). . Common shapes of commercial organic fertilizers are various shapes such as columnar and granular, and the color is generally yellowish brown or dark brown. Its main components are simply divided into organic matter, beneficial microorganisms, nitrogen, phosphorus and potassium. The production process mainly has the following aspects: 1. Open-air accumulation, exposure, primary decomposing and impurity removal of raw materials. 2. Enter the decomposing pool of the workshop, add the decomposed bacteria, continuously plow the material, promote the reproduction of the bacteria and accelerate the maturity. 3. After the raw materials are fully decomposed, they are dried in the drying workshop. 4. After adding a large amount of elements such as NPK, granulation and packaging are carried out.
The production process of organic fertilizer is made through a process of strict decomposing and sterilizing, but now the organic fertilizer advertisement on the market is “flying in the sky”. In the case of extremely fierce competition, many small workshop products are sub-charged in the market. Ok, the fish are mixed. Therefore, when choosing a vegetable farmer's friend, they must look for the logo on the packaging and choose the branded products produced by regular manufacturers. According to the introduction of the industry, in addition to identifying the quality of commercial organic fertilizer, in addition to identifying the logo of the outer packaging, you can also refer to several aspects for simple identification: 1. After opening the package, visually observe the shape of the product in the package, the particles are even. The size is basically the same, indicating that the process technology is high, the moisture content is up to standard, and the quality is reliable. Different shapes or powders indicate that the moisture content of the product is not up to standard or the product is placed for a long time, which destroys the original processing structure of the product and has a certain influence on the application effect of the product. 2, you can use the nose to smell the smell of the sample fertilizer, organic fertilizer after the full maturity and multi-process processing, still with the original taste of raw materials, such as soybean meal organic fertilizer with a light bean flavor, with fish bone powder as raw materials Organic fertilizers will have obvious astringency and so on. Conversely, it is not suitable for use with obvious odor, sourness or other odors that are inconsistent with the taste of the raw materials, indicating that the raw materials are deteriorated or the decomposing process is short. 3, take a small amount of sample into the water, good quality organic fertilizer, see water after dispersing evenly, no residue or a little residue of the material specific to the residue.
The commercial organic fertilizer has undergone a fully decomposed process, and its harmful substances and harmful fungi are greatly reduced, which reduces soil and environmental pollution. The application process is simple, and the soil and rhizosphere environment can be effectively improved after application. The nutrient supply in the early stage of crop growth is more obvious, so commercial organic fertilizer is gradually becoming the new favorite of farmers. However, we should correctly recognize the different effects of manure, commercial organic fertilizer and fertilizer, so as to be reasonably applied. After the application of commercial organic fertilizer, the early stage effect is obvious, which can obviously promote the growth of the crop in the early stage, but it is prone to the phenomenon that the bottom fertilizer is insufficient in the late stage, leading to premature aging of the crop. Therefore, when applying, the vegetable farmers should reasonably calculate the cost input according to the geographical situation, and rationally select and apply them, so as to effectively combine the manure, commercial organic fertilizer and chemical fertilizer, and lay a good foundation for the supply of nutrients with high yield and stable production.
