Embodiment

[0013] The first step: crop straw collection and crushing: After the crops are harvested, the straws are spread out in the field, dried, collected, and transported back to the production plant for temporary storage in the greenhouse, and kept dry in the greenhouse. Check the condition of the machine before starting the crusher. The crushing length of the straw is selected according to the use of the fertilizer. The length of the straw used as the base fertilizer is 5-8 mm, and the length of the seedling fertilizer is 3 mm. The straw should be kept dry to absorb the moisture in the manure.

[0014] The second step: collection and treatment of pig manure: collect pig manure, remove long debris, remove stones, bricks, metal shavings, etc., store it in a manure storage tank for later use, and the moisture content of the manure is 85-95%;

[0015] The third step: mix 1kg of crushed crop straw and 4kg of pig manure evenly, then add 150g molasses and 150g EM bacterial liquid, and mix evenl...

Abstract

The invention discloses a preparation method for acidic microbial organic fertilizer and the acidic microbial organic fertilizer prepared with the preparation method. The preparation method for the acidic microbial organic fertilizer is characterized by comprising the following steps: collecting crop straws; after the crop straws are aired and smashed, evenly mixing with pig manure at the mass ratio of 1:2-1:4; adding 1.5-3wt% of molasses and 1-3wt% of effective microorganisms (EM) fungicide used for fermentation; after the mixture is evenly stirring, putting into an aluminum foil bag with a vent valve; and carrying out complete anaerobic fermentation in a fermentation room of 28-30DEG C for 14-20 days to obtain the acidic microbial organic fertilizer. With the preparation method disclosed by the invention, a great quantity of crop straws and wastes, such as feces, urine and the like in a pig farm can be effectively utilized. The preparation method has the advantages of simple production technology, cheap and abundant raw material and low cost. The pH value of the obtained acidic microbial organic fertilizer is smaller than 5, and the acidic microbial organic fertilizer can be applied to saline-alkali soil on a large amount for a long time to effectively improve soil geology and lighten plant diseases and insect pests.

Description

Technical field [0001] The invention relates to an acidic biological organic fertilizer, belonging to the technical field of organic fertilizers. Background technique [0002] Over the years, due to the impact of chemical fertilizers on the market, the amount of farmyard fertilizers has become less and less, and some of them are not even used. Since chemical fertilizers did play a significant role in increasing crop yields when they were first used in the soil, people gradually ignored the use of farmyard manure. The long-term and large-scale use of chemical fertilizers has caused soil compaction, reduced soil permeability, water retention, and organic matter content, which eventually led to an increase in pests and diseases, and a reduction in the quality of crops. Organic fertilizer plays an important role in improving soil texture and promoting crop growth. The organic fertilizers produced by the commonly used aerobic fermentation processes are all alkaline, and their pH val...
