Embodiment 1

[0035] . A method of utilizing straw to produce biomass fertilizer, comprising the following steps:

[0036] A) Spread wheat straw on the bottom of an airtight container, spray the wheat straw with biogas slurry, the thickness of wheat straw is 1 / 10 of the height of the whole container; the mass ratio of biogas slurry to wheat straw is 1:10. The experimental location of this embodiment is selected from a rural area in Nanjing.

[0037] B) Spread a layer of biogas residue on the wheat straw. Both the biogas slurry and biogas residue in this example come from a biogas digester of a farmer in Nanjing.

[0038] C) Spread crop straws such as corn, wheat, rice, rapeseed and cotton on the biogas residue, and after spreading the crop straws, insert a hollow tube into the straw, and the other end of the hollow tube extends out of the airtight container; in this step The type of crop stalks has no influence on the present invention. The present invention is mainly for processing these...

Embodiment 2

[0044]. Same as Example 1, the difference is that Xuzhou was selected as the experimental site. The biogas slurry and biogas residue in this example come from a biogas digester of a farmer in Xuzhou. The thickness of the wheat straw in step A) is 1 / 5 of the height of the whole container; the mass ratio of the biogas slurry to the wheat straw is 1:2. In step D), a blower is used to ventilate the airtight container through the hollow tube for 120 minutes. After 35 days in step E), all the materials were taken out and dried in the sun to obtain straw decomposition products. In step F), the biomass fertilizer is configured, and the straw decomposition products are mixed with chemical fertilizers. The weight percentages of various components are: nitrogen fertilizer 15%, phosphorus fertilizer 15%, potassium fertilizer 10%, and the balance is straw decomposition products. Stir and mix to obtain bio material fertilizer.

Embodiment 3

[0046] Same as Example 1, the difference is that this time the experiment site is Lianyungang. The biogas slurry and biogas residue in this example come from a biogas digester of a farmer in Lianyungang. The thickness of the wheat straw in step A) is 1 / 8 of the height of the whole container; the mass ratio of the biogas slurry to the wheat straw is 3:10. In step D), a blower is used to ventilate the airtight container through the hollow tube for 60 minutes; in step E), all the materials are taken out and dried in the sun after 40 days, and the straw decomposition product is obtained; in step F), biomass fertilizer is prepared, and the straw decomposition product is mixed with chemical fertilizer, The weight percentages of various components are: 20% of nitrogen fertilizer, 25% of phosphorus fertilizer, 15% of potassium fertilizer, and the balance is straw decomposed matter, which is stirred and mixed to obtain biomass fertilizer.

Abstract

The invention discloses a method for producing a biomass fertilizer by using straw, which belongs to the field of biomass fertilizers. The method comprises the following steps: A) laying wheat straw on the bottom of an enclosed container and wetting the wheat straw through spraying of biogas slurry; B) laying a layer of biogas residue on the wheat straw; C) laying crop straw on the biogas residue and inserting a hollow pipe into the straw; D) introducing air into the enclosed container for 30 to 120 min through the hollow pipe by using a blower every other day; E) taking out all the materials for drying in the sun in 35 to 50 d so as to obtain a catabolite of the straw; and F) preparing the biomass fertilizer through uniform mixing of the catabolite of the straw with a fertilizer under stirring. According to the invention, decomposition of the straw can be realized through usage of a special microbial inoculums; the obtained biomass fertilizer can increase soil organic matters and beneficial microorganisms year after year and has the advantages of low cost and capacity of improving the ecological structure of soil.

Description

technical field [0001] The invention belongs to the field of biomass fertilizers, and more specifically relates to a method for producing biomass fertilizers by using straws. Background technique [0002] Straw usually refers to the remaining part of wheat, rice, corn, potato, oilseed, cotton, sugarcane and other crops after harvesting seeds. The stalks of these crops are generally abandoned and piled up in the field. They are relatively humid and cannot be completely burned when ignited. They will produce a large amount of smoke that is highly irritating to the eyes and respiratory tract, and contains a large amount of dust, liquid droplets and other pollutants. The smoke spreads with the wind, causing serious harm to the environment, people and other animals. Its main hazards are as follows. [0003] 1) Health threats. The burning of straw in the wild leads to a significant increase in the number of total suspended particles in the air, causing serious harm to human hea...
