Soil improved organic fertilizer using cow dung as main material and preparation method thereof

Abstract

The invention discloses a soil improved organic fertilizer using cow dung as a main material and a preparation method of the organic fertilizer. The soil improved organic fertilizer comprises the raw materials in parts by weight: 250-300 parts of dry cow dung, 50-70 parts of edible mushroom residues, 20-25 parts of sawing wood ash and 5-15 parts of bacillus subtilis fermentation. The preparation method comprises the following steps: (1) preparing the raw materials of the dry cow dung; (2) preparing the dry cow dung; (3) preparing the edible mushroom residues; (4) preparing the sawing wood ash; (5) preparing the bacillus subtilis fermentation; and (6) mixing and drying all raw materials. According to the organic fertilizer, the fertilizer efficiency can be achieved to the maximum limit, the rich content of beneficial biological bacterium in the organic fertilizer is realized, the acid-alkali degree is effectively controlled, the product is slightly weakly-alkaline, the acidity of the soil is reduced, and the contents of soil organic matters and nitrogen phosphorus and potassium are increased; and moreover, the organic fertilizer has low water content, and is easy to store, easy to use and low in user cost.

Description

technical field [0001] The invention relates to a red yellow soil acidic soil improvement method, in particular to a soil improvement organic fertilizer with cow dung as the main material and a preparation method thereof. Background technique [0002] In view of the rich soil resources of red-yellow soil and the potential for increasing production but the soil quality is declining, it is a problem in the current agricultural production to develop efficient, harmless and cheap soil improvement organic fertilizers. To this end, we aim to restore the degraded red-yellow soil and rapidly improve soil quality, and aim at the characteristics of accelerated acidification and low nutrient content in the dry land of red-yellow soil in the region. Rural non-point source pollution requires the development of a red-yellow soil improvement organic fertilizer with cow dung as the main raw material. Contents of the invention [0003] The object of the present invention is to provide...
