Now there are too many compound fertilizers sold on the market, manufacturers 20 kg of barrel fertilizer are my example, deep-sea fish peptide protein, chitin seaweed fertilizer, organic water-soluble fertilizer, special fertilizer for puffing fruit, special fertilizer for color change and sweetening, a large number of elements, balance. High potassium, high nitrogen, large packaging and small packaging, all kinds of ** activities are endless.
To promote the green development of agriculture, the supply of "green agricultural materials" cannot be less. Recently, Tongchuan Supply and Marketing Cooperatives invested more than 20 yuan to purchase a large number of fermented sheep manure and water-soluble fertilizer, which were distributed free of charge to local farmers and professional cooperatives, and at the same time provided field technical services to provide "green" power for agricultural harvest. With the change of fertilizer demand for agricultural production, multi-compound water-soluble fertilizer is an efficient, environmentally friendly and multi-functional fertilizer, and its types are diverse.
According to different classification criteria, it can be divided into different types. The following is an introduction to some common types of multi-compound water-soluble fertilizers according to different classification standards. According to the solubility, it can be divided into:1Fully water-soluble fertilizer: This fertilizer can be completely dissolved in water without any residue remaining. This fertilizer is high in nutrients and rich in nutrients, which can meet the multiple nutrients required for plant growth.
2.Semi-water-soluble fertilizer: This fertilizer is partially dissolved in water and produces some sediment or residue. This fertilizer is suitable for soil improvement and trace element supplementation, but attention needs to be paid to its solubility and application method. According to the production of raw materials can be divided into: 1Chemically synthesized water-soluble fertilizer: This fertilizer is prepared by chemical synthesis method, and its raw materials are mostly inorganic salts and complexes. This fertilizer is high in nutrients, but long-term use can have a negative impact on the soil environment. 2.Organic natural water-soluble fertilizer: This fertilizer is prepared by using organic matter as raw material and through biological fermentation and other processes. This fertilizer has a relatively low nutrient content, but it has the advantages of environmental protection, safety, and sustainability.
According to plant growth regulators, they can be divided into:1Plant growth regulator water-soluble fertilizer: In addition to being rich in nutrients, this fertilizer also adds plant growth regulators, which can regulate the growth metabolism of plants and improve the stress resistance and yield of plants. However, it is necessary to pay attention to its usage and scope of application. 2.Water-soluble fertilizer without growth regulators: This fertilizer contains only nutrients and does not add any plant growth regulators. This fertilizer is mainly used to supplement the nutrients needed by plants, but it can also improve the growth metabolism level of plants through reasonable fertilization methods. According to the nutrient content, it can be divided into:1High-concentration water-soluble fertilizer: This fertilizer has a high nutrient content and can meet the needs of plants for rapid growth. However, it is necessary to pay attention to the amount of fertilizer used and the way of fertilization to avoid problems such as root burning or excess nutrients. 2.Low-concentration water-soluble fertilizer: This fertilizer has a relatively low nutrient content, but can meet the long-term, stable needs of plants.
This fertilizer is suitable for base or top dressing, but needs to be adjusted according to the growth stage and needs of the plant. In addition to the above classification methods, multi-compound water-soluble fertilizers can also be classified according to different crop needs, soil conditions and other factors. When using multi-compound water-soluble fertilizer, it is necessary to choose the appropriate type and fertilization method according to the specific situation to achieve the best fertilization effect. At the same time, it is also necessary to pay attention to controlling the amount and frequency of fertilization to avoid environmental burden and waste of resources.
By cultivating leading enterprises, improving the first-class distribution system, creating demonstration models, and broadening supporting services, we will comprehensively improve the strength of "green agricultural materials" such as soil testing formula fertilizer, organic microbial fertilizer, and degradable and environmentally friendly pesticides. At the same time, we will actively explore new models of waste development and utilization such as pesticides and agricultural film packaging, combine UAV flight defense services, establish a scientific, accurate and ecological prevention and control concept, provide greener and more environmentally friendly agrochemical services for the majority of farmers, and truly achieve a "golden" harvest in a green way while promoting the high-quality development of agricultural green transformation.
