Biological organic fertilizer with effect of controlling soil-borne diseases and preparation method of biological organic fertilizer

Abstract

The invention discloses a biological organic fertilizer with an effect of controlling soil-borne diseases and a preparation method of the biological organic fertilizer. The biological organic fertilizer is prepared from the following raw materials in parts by weight: 100-160 parts of excrements of livestock, 60-80 parts of straws, 20-30 parts of wormcast, 0.4-0.6 part of a compound microorganism bacterium agent, 0.1-0.3 part of a fermentation accelerator and 3-5 parts of pururan. According to the biological organic fertilizer with the effect of controlling soil-borne diseases, disclosed by theinvention, on one hand, the soil fertility can be improved, and formation of a granular structure of the soil is facilitated, so that soil properties are improved, the activities of defense enzymes are improved, supply of moisture and nutrients of a relative overground part, cytokinin and other active materials is ensured, enhancement of normal activity of the overground part of plants is promoted, the crop yield is obviously increased, and a good foundation is laid for enhancing the disease resistance of the plants; on the other hand, pathogenic bacteria can be inhibited, the soil microflorais effectively improved, and the soil-borne diseases are inhibited.

Description

technical field

[0001] The invention belongs to the technical field of bio-organic fertilizers, and in particular relates to a bio-organic fertilizer capable of preventing and controlling soil-borne diseases and a preparation method thereof. Background technique

[0002] With the separation of aquaculture and planting in our country, there is not enough farmland to absorb a large amount of aquaculture waste produced by large-scale and intensive aquaculture, which has a serious impact on the ecological environment. However, the application of chemical fertilizers in farmland is increasing year by year, and the bottleneck of contribution to crop yield is becoming increasingly prominent.

[0003] Fertilization in my country's agricultural production is characterized by partial application of chemical fertilizers. The long-term application of large amounts of chemical fertilizers reduces the quality of crops, causes soil compaction, decline in organic matter, damage to the micro...
