Method. for preparing quick-acting compound organic fertilizer

Abstract

A quick-acting composite organic fertilizer is prepared proportionally from the powder of edible fungus, bran and stalk, fresh droppings or dung of fowls and animals, water, N source and living microbe preparation EM through mixing, stacking, fermenting, filtering to obtain liquid extract, and adding xanthonic acid and amino acid proportionally. It can increase the yield of agricultural crops by 10-20%.

Description

technical field [0001] The invention relates to a compound fertilizer and a preparation method thereof, in particular to a compound fertilizer made by compounding various organic fertilizers or organic and inorganic fertilizers, and belongs to the field of fertilizer technology. Background technique [0002] Fertilizer is the food for the growth of various plants. In addition to providing various nutrients necessary for plant growth, fertilizer can also improve the soil. Reasonable application of fertilizer is an important measure to increase crop yield. Traditional agricultural production mainly uses organic fertilizers, while modern agriculture uses more chemical fertilizers. In recent years, with the increasing demand for agricultural products, the amount of chemical fertilizers is increasing and there are more and more varieties. Compared with traditional organic fertilizers, they are easy to dissolve in water, easy to be absorbed and utilized, and have rapid effects. Pe...

Problems solved by technology

However, while the extensive use of chemical fertilizers has brought huge benefits to agriculture, it has also caused a series of negative effects, such as soil compaction and barrenness due to the reduction of soil organic matter, and large-scale occurrence of diseases and insect pests due to micro-ecological imbalance.

With the emergence of bio-organic fertilizers and organic-inorganic compound fertilizers, the above-mentioned problems of single application of chemical fertilizers have been solved to a certain extent, but there are problems: the application of organic fertilizers without harmless treatment is likely to cause pests and diseases; Organic fertilizers such as dried chicken manure are solid, and their aqueous solutions are slag-containing liquids, which are difficult to apply and are not conducive to water-saving irrigation of economic crops; ordinary organic fertilizers are in the form of slag-containing solids, which are unevenly dispersed after being applied to the soil. Slow, especially in the germination period and spreading period of crops, it is difficult to combine with the plant root system to exert its due efficiency

At present, using industrial amino acid or mineral humic acid as quick-acting organic fertilizer is a more commonly used method, but there are also defects, that is, industrial amino acid has higher nitrogen-containing ions and lower pH value (powder pH value is about 4), This is not good for nitrogen avoiding crops such as watermelon, potato, sugar beet, tobacco, sugar cane, etc.

Mineral humic acid is prone to flocculation and precipitation in hard water and acidic soil, and loses its activity.
