In the past few years, there was a saying in the countryside: “One policy depends on the sky, and the grain production depends on diammonium.†As the grain output increases, the soil potassium deficiency has already been shown. Now farmers have more choices of ternary compound fertilizer. .
The three major trends in the development of compound fertilizer: The first is the specialization of multiple varieties. Different crops have different special fertilizers, and special fertilizers are developed according to the law of crop growth and development and the amount of fertilizer absorbed. When farmers choose compound fertilizer, they should choose the corresponding special fertilizer for different crops. If it is not used, it will violate the law of crop absorption, and the potential for crop yield will not be realized, and some nutrients will be wasted. The second is multi-functional medicinalization. The combination of pesticides and fertilizers eliminates the pesticide dressing procedure. Once applied, it can not only ensure the nutrients needed for crops, but also prevent underground pests and seedlings, and play multiple effects. The third is long-term high concentration. With the development of agricultural production, high-concentration and long-acting compound fertilizer is more and more popular among farmers. The application of this type of fertilizer reduces the amount of fertilization, facilitates cultivation, eliminates the problem of topdressing, reduces labor and improves fertilizer utilization. , saving labor, saving effort, saving time, improving quality and efficiency.
How to choose compound fertilizer? Look at the packaging. Qualified products are double-layered to protect against moisture and moisture. There are three license numbers on the exterior of the package: the production license number, the business license number, the product quality registration certificate number, and the three major nutrient element contents of nitrogen, phosphorus and potassium, and the manufacturer and address. Open the outer packaging and have a product joint instruction manual.
Second, look at the physical properties of compound fertilizer. The compound fertilizer with good product quality has uniform particle size, no agglomeration and no powder.
Third, the production equipment and production technology of the regular manufacturers are relatively advanced, the products produced are evenly distributed, the nutrients are balanced, and the quality is stable. The product production is developed by experts on the soil nutrient status and crop fertilizer requirements. The formula is scientific and reasonable, with strong pertinence, full nutrients and sufficient content.
Fourth, it is necessary to select a suitable compound fertilizer for local use. Most of the compound fertilizers produced locally are based on the soil nutrient content of the region and surrounding areas, the fertilizers produced by crops and the fertilizer effect, and are highly targeted. Some farmers blindly purchase compound fertilizers that are not suitable for local application, which not only affects crop growth and development, but also causes waste of individual nutrients and affects production.
Five bogey use "double chlorine" compound fertilizer for years. "Dichloro" compound fertilizer is a compound fertilizer produced by using ammonium chloride and potassium chloride as raw materials, and the chlorine ion content is high. Chloride ion is a trace element required for growth, and an appropriate amount can promote the growth of the action, and excessive amount will cause fat damage. If the "dichloro" compound fertilizer is applied year after year, the recommended amount of chlorine chloride soil is large, and the excessive absorption will cause "chlorine damage", and the soil will also suffer from "salt damage".
Compound fertilizer is generally used as a base fertilizer. For the application of the basic application method before sowing, there is a kind of fertilizer applied in the first line, and the second line of seed fertilizer is applied by lateral deep application. At present, it is best to see the compound fertilizer and animal husbandry as the long-acting compound fertilizer. The lateral deep application position is generally 5-7 cm deep at the side of the fertilizer. Side-deep application achieves seed fertilizer isolation and avoids burning seedlings.
