Organic fertilizer prepared by taking biochar and algae as raw materials

Abstract

The invention discloses organic fertilizer prepared by taking biochar and algae as raw materials. The organic fertilizer is prepared from the following components: 550 to 650 kg of the biochar, 280 to 320 kg of alga extract, 25 to 35 kg of a mixed bacteria solution and 55 to 65 kg of chitosan hydrolysate, wherein the biochar is prepared through the following steps: drying cotton straws, corn straws or / and potato seedlings in the sun until the water content is below 20 percent, then cutting or smashing, putting the cotton straws, the corn straws or / and the potato seedlings in a carbonizing oven, and carbonizing for 2.5 to 3.5 hours under 420 to 480 DEG C; obtaining charcoal after carbonizing is completed, filtering by using water, cooling to a room temperature, then drying the charcoal, and smashing, thus obtaining the biochar. According to the organic fertilizer prepared by taking the biochar and the algae as the raw materials, disclosed by the invention, the nutrition is rich and comprehensive, other chemical fertilizer is not required to be added, the nutrition for growth of plants can be provided, the plant growth is promoted, and a fruiting rate is increased; a practice proves that the organic fertilizer has an obvious yield increment function on cucumbers.

Description

technical field [0001] The invention relates to an organic fertilizer prepared from biochar and seaweed. Background technique [0002] Most of the world-wide aquaculture and planting industries use chemical antibiotics, growth agents, pesticides, etc. to promote the growth of animals and plants, prevent plant epidemic diseases, etc. Although the effect is obvious, it often causes excessive agrochemical residues and environmental pollution. Adverse consequences also have a great impact on the quality of crops. In particular, excessive application of simple chemical fertilizers such as nitrogen fertilizers will intensify soil compaction and reduce soil fertility, making it difficult for the quality and nutrition of crop products to meet people's needs, let alone meet the requirements of green food, and cause serious environmental pollution. [0003] Seaweed fertilizer is a natural seaweed extract, which is harmless to humans and animals and has no pollution to the environment...

Problems solved by technology

In addition, in recent years, algae such as Enteromorpha have flooded coastal areas such as Yantai, Weihai, and Qingdao, seriously polluting the environment and even affecting coastal landscapes.

[0006] At present, most manufacturers at home and abroad mainly use chemical hydrolysis to produce seaweed fertilizer, that is, use strong acid and strong alkali to treat seaweed under severe conditions of high temperature and high pressure. lots of active ingredients

In addition, there is no report on the compounding of seaweed and biochar to prepare organic fertilizers.
