Organic fertilizer for agriculture

Abstract

The invention discloses an organic fertilizer for agriculture. The organic fertilizer comprises the following raw materials in parts by weight: 15-25 parts of straw powder, 8-12 parts of poultry manures, 3-5 parts of vitamins, 4-8 parts of plant ash, 1-2 parts of strain powder, 3-5 parts of nanometer calcium carbonate powder and 6-13 parts of humic acid. In such a manner, the organic fertilizer for agriculture, disclosed by the invention, takes organic nutrients as main components, is reasonably prepared with a proper amount of inorganic fertilizers and not only can provide comprehensive and reasonable nutrients for crops, but also can comprehensively improve the soil quality, so that the soil fertility is increased, and the cost is low; after long-term use of the organic fertilizer, soil which is acidized and alkalized or salinized and alkalized and other soils of which the quality is reduced are improved; the fertilizer efficiency is fast and lasting, and the fertilizer damage cannot be caused; comprehensive and balanced nutrients can be provided for the crops, so that the crop disease resistance is greatly improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to an organic fertilizer for agriculture. Background technique [0002] At present, the world is facing severe problems of population increase and environmental degradation, and the extensive use of inorganic fertilizers in agricultural production will also make environmental degradation more serious. The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year; A...

Problems solved by technology

The deficiencies of this inorganic fertilizer mainly include: destroying the soil, resulting in a decrease in the content of soil organic matter, an imbalance in the proportion of various nutrients, acidification and compaction of the soil, and serious damage to the physical and chemical properties of the soil and soil microbial flora, resulting in its water retention. Fertilizer and air permeability are poor, which is difficult to meet the actual growth needs of crops; crops are highly dependent on chemical fertilizers and pesticides, and the amount of use must be increased year by year; After farmland, the actual utilization rate is only 30% on average, and most of it flows into rivers and lakes with farmland drainage or remains in the soil, plants and crops, which not only brings environmental pollution but also endangers the safety and health of human beings and lives. These have become sustainable agriculture. Obstacles to sexual development; the above conditions can be improved by applying organic fertilizers, but many varieties of organic fertilizers in China are uneven, have single effects, and are sold at high prices
