Farmyard organic planting fertilizer and preparation method thereof

Abstract

The invention relates to the field of fertilizers, and specifically relates to a farmyard organic planting fertilizer and a preparation method thereof. The fertilizer is characterized in that the fertilizer is composed of the raw materials of, by weight, 20-25 parts of tea tree, 12-18 parts of mulberry tree, 23-30 parts of crop stalks, 18-24 parts of plant ash, 5-8 parts of oil cake residue, 7-12 parts of night soil, and 30-35 parts of livestock and poultry manure. The preparation method comprises the steps of: (1) material preparation and processing; (2) drying; (3) mixing; (4) fermentation and composting; (5) drying; (6) crushing and sieving; and (7) packaging and storing. According to the invention, discarded crop stalks and leaves during an agricultural planting process and manure discharged from an ecological culture process are mainly utilized as raw materials. Environment pollution is reduced, and the preparation method is simple and is easy to popularize. The prepared farmyard fertilizer is rich in nutrients, and is easy to absorb. Fertilizer effect is long-lasting. The fertilizer can be widely utilized.

Description

Technical field: [0001] The invention belongs to the field of fertilizers, and in particular relates to a farm organic planting fertilizer and a preparation method. Background technique: [0002] Ecological agriculture and green food have become the strategic goals of my country's agricultural development. Protecting the environment and protecting arable land are important guarantees for the development of ecological agriculture. Long-term application of chemical compound fertilizers in the agricultural production process will destroy the soil structure, cause the cultivated layer to become shallow, and plant The agricultural products produced are not tasty, thereby reducing the quality of agricultural products. Therefore, the demand for farmyard manure application on arable land is becoming more and more urgent. Applying organic farmyard manure can not only adjust soil acidity and alkalinity, improve soil structure, loosen soil, and maintain soil fertility; It is convenient...

Problems solved by technology

[0003] In modern agricultural production, the study of farm organic fertilizers is of great significance for organic farming. There have been many studies on organic farm fertilizers, and there are many types. According to different geography, the preparation methods and processes are different, but most The production and processing of most organic farm fertilizers is difficult, and it is not easy to promote; at the same time, most of the fertilizers are prepared by adding chemical fertilizer components for mixed fermentation. The duration is also relatively short, and the added chemical fertilizer components will also affect the quality of crops, and the fertilizer residues left behind cannot be degraded and corrupted for a long time, which is likely to cause secondary pollution of the environment

More importantly, the stems and branches of many crops are discarded during the agricultural planting process, and the feces discharged during the ecological breeding process are not well utilized, causing a lot of pollution to the environment. How to recycle these products It is also a very important research topic
