A special organic-inorganic compound fertilizer for corn and preparation method thereof

Abstract

The invention discloses a special organic / inorganic compound fertilizer for corn and a preparation method thereof, belonging to the fields of agricultural resource recycling and environment protection. The invention combines two aspects of the agricultural waste reclamation utilization and novel fertilizer manufacture; inorganic chemical fertilizer is added into the chicken manure and tikitiki according to growth characteristics and nutrient requirement of corn to prepare nutritional organic / inorganic compound fertilizer. The organic matter content of the compound fertilizer reaches 20.35-24.05%, and the nutrient thereof accounts for 20.92-26.85% of the total nutrient, wherein, nitrogen content is 8.72-10.13%, phosphorus pentoxide content is 3.85-7.07% and potassium oxide content is 8.35-9.65%. The invention solves the problem of post processing of chicken manure, avoids rural environment pollution, has long-acting fertilizer property of the organic fertilizer and quick-acting fertilizer efficiency of the inorganic fertilizer, obvious production increasing effect, simple preparation process and low requirement on machinery equipment manufacture, saves cost, and is beneficial for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the fields of agricultural waste recycling and fertilizer production, and in particular relates to a special organic-inorganic compound fertilizer for corn, which uses chicken manure compost and inorganic fertilizers as components. Background technique [0002] With the rapid development of the livestock and poultry breeding industry, the amount of various livestock and poultry wastes has also increased sharply. If they are not treated effectively, it will bring serious non-point source pollution to the entire rural environment, and even affect people's normal life. production and life. Therefore, it is particularly important to strengthen the prevention and control of livestock and poultry waste pollution, and the resource utilization makes the value of these agricultural wastes manifest. Chicken manure is one of the most common livestock and poultry farming wastes in rural areas. According to the determination of relevant de...

Problems solved by technology

However, the proportion of organic granular fertilizer is 14%-15%, and the organic matter content only accounts for 5%-7.5% of the total amount of organic-inorganic long-acting corn special compound fertilizer. In addition, the raw materials used in organic granular fertilizer include livestock Poultry manure, bean cake, straw, etc., the raw material composition is relatively complex, and the whole preparation process is relatively cumbersome, and the requirements for manufacturing equipment are also high, which greatly increases the cost
