Pepper organic fertilizer based on stillages and production method of pepper organic fertilizer

Abstract

The invention discloses pepper organic fertilizer based on stillages and a production method of the pepper organic fertilizer. The pepper organic fertilizer is prepared from the components in parts bymass: 90 parts of stillages, 6-8 parts of straws, 2 parts of mineral powder, 3-5 parts of quick lime and 0.2-0.3 part of a culture. According to the method for producing the stillage organic fertilizer, the fermentation time is short, the temperature is controllable, and the method is suitable for cultivation of pepper crops. The stillage organic fertilizer obtained by the method is prepared formthe components in percentage: 80% of organic matter, 3.78% of N, 2.0% of P2O5, 1.68% of K2O and 7.46% of total nutrients, wherein the pH is about 6.5, and the moisture content is 28%. The mortality of roundworm eggs and fecal coliform group number indexes meet the requirements for the executive standard (NY884-2012) of a bio-organic fertilizer.

Description

technical field [0001] The invention relates to the comprehensive utilization of distiller's grains, in particular to a pepper organic fertilizer based on distiller's grains and a production method thereof. Background technique [0002] The annual production of liquor in my country is about 9 million kiloliters. According to the ratio of 1:3 between liquor and distiller's grains, the annual discharge of distiller's grains is as high as 2.7×10 7 t. Distiller's grains have high acidity and a water content of more than 60%. They are easily corrupted and inconvenient to store. If they are not disposed of in time, they will easily cause great pollution to the environment. As a by-product of liquor production, distiller's grains are rich in nutrients such as crude protein, crude fat, crude starch, crude fiber, and nitrogen-free extracts, as well as inorganic elements such as phosphorus and potassium, and pentose and total sugar. Excellent source of organic fertilizer. Using ric...

Problems solved by technology

[0006] However, the natural fermentation and utilization of distiller's grains used in the prior art has a poor effect, the fermentation process is difficult to control, the consumption time is long, and the quality is uneven

Immature distiller's grains are acidic, directly applied to the soil may cause environmental problems and the occurrence and aggravation of soil-borne diseases, and the fertilizer effect is not long-lasting
