Animal wastes are commonly considered the excreted materials from live animals. However, under certain production conditions, the waste may also include straw, hay, wood shavings, or other sources of organic debris.

Method for preparing organic fertilizer by using plant residues as raw material

The invention relates to a method for preparing an organic fertilizer by using plant residues as a raw material. The method comprises the following steps: crushing the raw material to below 20mm, stirring and mixing the broken material with animal wastes or an inorganic fertilizer; controlling the C/N ratio of the mixed materials to be (15-35) to 1 and the pH to be 6-9; adding water, so that the moisture content in the mixed materials in the step (2) is 55-70wt%; adding a first composite microbial agent to ferment; after once fermentation, raising the temperature of windrows to above 50 DEG C; and spraying a water-dispersed second composite microbial agent to ferment for the second time. With plant residues heap corruption (composting) as a biological process for succession of a microbial community, through inoculation of exogenous complex microbial agents, efficient decomposition on agricultural wastes is facilitated; different composite microbial agents are respectively added at different composting stages; and a small amount of additives (animal wastes, urea, ammonium nitrate and the like) are added, so that the composting speed is increased, and the quality of the product organic fertilizer is really improved.

Controlled-release compound pesticide fertilizer

The invention discloses a controlled-release compound pesticide fertilizer. The controlled-release compound pesticide fertilizer is characterized by being prepared from the following raw materials in parts by weight: 60-70 parts of biological fertilizer, 20-30 parts of pesticide fertilizer, 2-5 parts of calcium phosphate, 2-5 parts of magnesium sulfate, 0.5-1 part of zinc sulfate, 0.5-1 part of borax and 0.5-1 part of compound sodium nitrophenolate; the biological fertilizer is formed from the following materials in parts by weight: 30-50 parts of sugarcane molasses alcohol wastewater, 30-50 parts of animal waste, 20-30 parts of bagasse, 20-30 parts of straws and also a fermenting microbial agent accounting for 0.2-5% of the total weight of the materials through microbial fermentation; the pesticide fertilizer is formed by crushing the following materials in parts by weight: 20-30 parts of tea seed cake and 0.5-2 parts of chlorantraniliprole, mixing the materials evenly, pelleting, and coating the granular pesticide fertilizer by using a coating material accounting for 2-10% of the total weight of the materials. The controlled-release compound pesticide fertilizer is scientific in formula, and capable of providing comprehensive nutrition for crops, promoting the growth of the crops and improving the quality of soil, and also has the effects of insect prevention and insect killing; the active ingredients are slowly released in the growth process of the crops, and therefore, the utilization rate of the fertilizer and the pesticide can be increased and the pollution on the environment caused by the pesticide and the fertilizer can be reduced.

Animal carrion and static compost hazard-free treatment method of products thereof

InactiveCN101838166AEnvironmental degradationEconomic degradationBio-organic fraction processingAnimal corpse fertilisersFecesPlant disease
The invention relates to an animal and a static compost hazard-free treatment method of products thereof, belonging to the field of environment protection. The method is characterized by comprising the step of simultaneously mixing carbon source accessories such as dry hay and the like and nitrogen source accessories such as animal wastes and the like with animal carrion and products thereof for composting. Based on the compost construction method, a single-layer or multi-layer construction method is adopted according to animal weight. After compost is constructed, the temperature of the compost is increased to 55 DEG C and maintained for more than 3 days or is increased to 45 DEG C and maintained for 7 days, so that disease microorganisms are inactivated basically. After the compost is constructed, the compost is statically treated and turned after a certain period of time, and the process is repeated until the compost is fermented so that the compost becomes thoroughly decomposed and can be applied. The invention is safe, environmental friendly and economical, and cheap compost accessories easily obtained in villages, such as dry hay, straw, animal wastes and on the like, are used for decomposing the animal carrion; the animal carrion and the products thereof can be thoroughly decomposed and converted into a beneficial green organic plant fertilizer; and a feasible method is provided for an application in animal epidemic outbreaks.

Method for making biological organic fertilizer by using rice straws as main raw material

The invention relates to a making technology of a biological organic fertilizer, which belongs to the field of crop straw deep processing, and in particular relates to a method for making the biological organic fertilizer by using rice straws as a main raw material. More specifically, rice straws are adopted as the main raw material; animal wastes and pond sludge are adopted as auxiliary materials; and the main raw material and the auxiliary materials are fermented by EM (Effective Microorganism) strain, which is enlarged in multiple stages, so as to obtain the biological organic fertilizer. The method for making the biological organic fertilizer by using rice straws as the main raw material, provided by the invention, has the advantages of wide raw material source, low price, simple product making process and high beneficial bacteria content in the formed product as well as has the characteristics of increasing soil organic matter, improving the soil structure, promoting the soil microbial activities, enhancing the soil fertility keeping and fertility supplying properties and the like; and the crop yield is also obviously increased, the crop quality is improved and the fertilizer input can be reduced in the product application; therefore, the production cost is reduced and the farmer income is increased.
