Special biological type organic-inorganic compound fertilizer for peanuts

Abstract

The invention discloses special biological type organic-inorganic compound fertilizer for peanuts. The special biological type organic-inorganic compound fertilizer is prepared from original fertilizer, an organic material and a microbial agent, wherein the original fertilizer contains 30%-40% by mass of N+P2O5+K2O, N content is 12%-15% by mass, P2O5 content is 8%-12% by mass, K2O content is 10%-13% by mass, organic matter content is higher than or equal to 15% in parts by mass, moisture (fresh sample) content is lower than or equal to 30% in parts by mass, total viable count is larger than orequal to 0.02 billion / g, urea formaldehyde content is 3%, active humic acid content is 5%-10%, and the total amount of amino acid is 0.4%-3%. With addition of a certain amount of urea formaldehyde, fertilizer particle strength is effectively improved, and fertilizer quality is improved; with addition of a certain quantity of humic acid, amino acid and the microbial agent, nutrients required for peanut lifetime are effectively guaranteed, fertilizer efficiency and crop yield are increased, quality is improved, and the compound fertilizer has special effects that land utilization and land maintenance are combined, long acting and quick acting are synergistic, water retention and fertilizer conservation effects are obvious and the like; compared with only application of nitrogen, phosphorusand potassium fertilizer, absorption and utilization rate of nutrients can be increased by about 30%-50%, peanut yield can be remarkably increased, and peanut quality can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizers, in particular to a special bio-organic-inorganic compound fertilizer for peanuts. Background technique [0002] Over the years, in order to increase production and ensure supply, agricultural resources have been super-utilized, excessive input of chemical fertilizers, especially the continuous expansion of the production scale of cash crops, coupled with the accelerated transfer of rural labor force, the rapid development of industrialization, livestock and poultry breeding waste, industrial waste and urban Insufficient utilization of organic resources such as sludge brings about cost increases and environmental pollution, and also affects product quality and production efficiency. [0003] Organic resources contain a large amount of organic substances, which not only provide various nutrients needed for crop growth, but also improve the structure of the soil, enhance the ability...
