Problems solved by technology

At present, many commercially available fertilizers are general-purpose fertilizers, and some rice-specific fertilizers are not accepted by farmers due to their narrow applicability. Therefore, there is an urgent need in the market for a long-acting rice-specific organic-inorganic compound fertilizer with wide applicability.

Abstract

The invention discloses a special rice organic-inorganic compound fertilizer and a preparation method thereof, belonging to the agricultural resource recycling and environmental protection fields. The invention combines the two areas of the resource recycling of agricultural wastes and the development of new fertilizers together and adds fowl manure and rice bran in the inorganic fertilizer according to the growth characteristics and nutritional needs of rice to prepare the nutritious organic-inorganic compound fertilizer. The organic matter content of the compound fertilizer is 20.35%-25.16%, the total nutrient content is 19.57%-26.44%, wherein the nitrogen content is 8.9%-9.96%, the phosphorus pentoxide content is 3.99%-6.93%, and the potassium oxide content is 6.68%-9.55%. The compound fertilizer of the invention solves the post processing problem of fowl manure, avoids the pollution to the rural environment and combines the organic and inorganic nutrients so that only one basic fertilization is performed without aftermanuring so as to achieve the aim of saving cost, improving effect and increasing yield; in addition, the preparation process is easy, the requirement of machinery equipment used for preparation is low, the cost is saved and the compound fertilizer is applicable to large-scale promotion and application.

Description

Technical field [0001] The invention belongs to the fields of livestock and poultry waste treatment and utilization and fertilizer production, and particularly relates to a special organic-inorganic compound fertilizer for rice using chicken manure compost and inorganic fertilizer as raw materials. Background technique [0002] The recycling of agricultural resources is an important guarantee for restoring production and rebuilding the ecological environment in the disaster area. In the recycling of agricultural resources, the use of agricultural waste is the focus and difficulty of its research. In the early days, agricultural waste was not recycled as a resource in the world, so it became one of the main pollution sources that polluted the ecological environment. In recent years, with extensive international attention and key research on ecological and environmental issues, the recycling of agricultural waste has become an important means of energy conservation and emission re...
