Problems solved by technology

Moreover, diosgenin wastewater has large chroma (up to several thousand), high concentration of organic pollutants (chemical oxygen demand COD> 10 g·L -1 ), high acidity (pH=1-2, SO 4 2- The content is 400-800mg·L -1 ), high temperature (55-65°C) and other characteristics, the treatment is difficult. If it is only discharged into the environment after simple neutralization and precipitation, it will cause serious pollution to the surrounding water and soil

Abstract

The invention belongs to the technical field of crop fertilizers, and specifically discloses a preparation method and a use method of a special fertilizer for konjac. The preparation method of the special fertilizer for konjac comprises the following steps: (1) Sterilization and extraction: adjust the pH of the diosgenin wastewater with water, then mix it with konjac skin dregs, press and filter after heating and keeping warm, to obtain filtrate A and filter residue B; ( 2) Ingredients before fermentation: Mix filter residue B, diosgenin waste residue, rapeseed cake, distiller's grains, and cow dung to obtain ingredient C, adjust the moisture content and pH of ingredient C, add starter, stir, and pile up into a cuboid pile; (3) Fermentation: Cover the pile with a plastic film for fermentation to obtain fermented fertilizer D; (4) Compounding: Mix fermented fertilizer D, superphosphate, silicon calcium magnesium potassium fertilizer evenly, and dry in the air. The special fertilizer for konjac prepared by the invention has high humification degree, plant germination index and effective bacterial count, which enhances the disease resistance of konjac plants and improves the yield and quality of konjac bulbs.

Description

technical field [0001] The invention belongs to the technical field of crop fertilizers, and in particular relates to a method for preparing a special fertilizer for konjac and a method for using the same. Background technique [0002] Konjac is a perennial herbaceous plant of the Araceae family Amorphophallus, which originated in the tropical rainforest climate zone. It is a herbaceous plant in the understory of the forest. It is suitable for growth and development under the ecological conditions of warm and humid, scarce direct sunlight, loose and fertile soil rich in organic matter. The underground tubers of konjac are economic organs. The roots of konjac are fleshy string-like fibrous roots and shallow root systems. Most of them are distributed horizontally in the soil 10 cm below the soil surface. The soil is required to be deep, loose, rich in organic matter and transparent. Good loam or sandy loam. [0003] There are two maximum restrictions on the soil suitable for ...
