Embodiment 1

[0021]This example is an example in which a biochane fertilizer is prepared.

[0022]A prepared bio-carbon base fertilizer, bioaccharide fertilizer is made of raw materials from the following ratio: 20-30% of humic salts, 10-20% pig manure, 10-15% straw, 10-15% charcoal, avian bone 10-15%, fruit shell 10-15%, urea 1-2%, calcium phosphate 1-2%, 1-2% of potassium chloride, 1-2% magnesium sulfate, 1-2% ammonium chloride.

Embodiment 2

[0024]This example is an example of a method of preparing a biochane fertilizer.

[0025]A method of preparing biochane fertilizers, including the following steps:

[0026]S1: Put the appropriate amount of charcoal, avian bone, and fruit shell into the pulverizer, 1200 mesh sieves;

[0027]S2: Put the appropriate amount of humus and pig manure into the stirring tank, stirred at a low temperature of 25 ° C for 48min;

[0028]S3: Place charcoal, avian bone, fruit shell fine powder, and straw ash are placed in a stirring tank, add charcoal, avian bone, fruit shell fine powder, and straw gray weight, three times the weight of the straw, continuously stirring 2-3h;

[0029]S4: Put the appropriate amount of urea, calcium phosphate, potassium chloride, magnesium sulfate, and ammonium chloride, in a stirring tank, continuously stirred at a temperature of 80 ° C to evaporate, and form a fertilizer.

Embodiment 3

[0031]On the basis of Example 1, the sharing of humic culture was 20%, and the share of pig manure was 10%, the shades of straw ashes were 15%, and the proportion of charcoal was 15%, and the share of the avian bone was 15%. The share was 15%, the share of urea was 2%, the magnification of calcium phosphite was 2%, and the share of potassium chloride was 2%, the magnification of magnesium sulfate was 2%, and the ammonium chloride was 2%.

Abstract

The invention discloses a biochar-based fertilizer and a preparation method thereof. The biochar-based fertilizer is prepared from the following raw materials in percentage: 20-30% of humus soil, 10-20% of pig manure, 10-15% of straw ash, 10-15% of charcoal, 10-15% of poultry bones, 10-15% of fruit shells, 1-2% of urea, 1-2% of calcium superphosphate, 1-2% of potassium chloride, 1-2% of magnesium sulfate and 1-2% of ammonium chloride. According to the prepared biochar-based fertilizer and the preparation method thereof, the biochar-based fertilizer prepared by matching humus soil and pig manure with straw ash, charcoal, poultry bones and fruit shells is loose in pores and good in air permeability, can purify water and is beneficial to reducing the use of chemical fertilizers; and the fertilizer can increase crop yield, improve agricultural product quality, improve soil fertility, reduce nutrient loss, and reduce soil heavy metals.

Description

Technical field[0001]The present invention relates to the field of biocarbon-based fertilizers, and more particularly to the preparation of biochane fertilizers and preparation methods thereof.Background technique[0002]At present, due to unreasonable fertilizer structure and its fertilization methods, there is a variety of problems such as soil nutrient disorders, acidification, fattening, low nutrient utilization rate, and facial source pollution. At the same time, with the rapid development of our province, the rapid development of urbanization, the heavy metal pollution of cultivated land is becoming more serious, and the harm of soil organic pollution and potential harm are greater. The reduction of cultivated land, the decline in soil degradation and quality have become a major threat to the safety supply of agricultural products in agricultural development, ensuring the safety supply of agricultural products, and it is necessary to improve the improvement in the fertilizer ind...
