Problems solved by technology

However, due to the long-term application of chemical fertilizers in most areas of my country, the soil ecological environment, soil physical and chemical properties, and soil microbial flora have been damaged to varying degrees. Fertility supply capacity has declined, soil compaction has intensified, and the dominant population of rhizosphere soil microorganisms has decreased significantly, which has polluted the quality of agricultural products to a certain extent, making it difficult for products to meet the requirements of pollution-free food

Embodiment 1

[0033] A method of using straw to make charcoal and charcoal fertilizer , including the following steps:

[0034] 1) Will straw Crush until the length is 50-55mm, let stand for 24h;

[0035] 2) After the above pulverized straw compressed into blocks so that the resulting straw The water content in the block is ±0.2g / cm 3 ;

[0036] 3) the obtained in step 2) straw The block is laid in the open carbonization kiln, and it is ensured when laying straw The upper surface of the block is flat to avoid raw material vacancies, so that straw The block fills the carbonization kiln, and at the same time straw The upper surface of the block is covered with a layer of 4cm-thick crushed material; firstly, the ignition positions are evenly distributed and equidistant on the upper surface of the crushed material. Oxygen supply, after igniting the surrounding ignition positions for 30 minutes, ignite the ignition positions in the carbonization kiln. After 20 minutes, ignite the...

Embodiment 2

[0041] A method of using straw to make charcoal and charcoal fertilizer , including the following steps:

[0042] 1) Will straw Crush until the length is 50-55mm, let stand for 24h;

[0043] 2) After the above pulverized straw compressed into blocks so that the resulting straw The water content in the block is ±0.2g / cm 3 .

[0044] 3) the obtained in step 2) straw The block is laid in the open carbonization kiln, and it is ensured when laying straw The upper surface of the block is flat to avoid raw material vacancies, so that straw The block fills the carbonization kiln, and at the same time straw The upper surface of the block is covered with a layer of 4-6cm thick crushed material; firstly, the ignition positions are evenly distributed and equidistant on the upper surface of the crushed material. After igniting the surrounding ignition positions for 40 minutes, ignite the ignition positions in the carbonization kiln. After 30 minutes, ignite the ignition pos...

Embodiment 3

[0049] Repeat embodiment 2, difference is, change gibberellin into triiodobenzoic acid, other conditions are constant, obtain carbon-based active organic fertilizer. According to the detection method of NY798-2004-T, it is measured that the moisture content of the obtained carbon-based active organic fertilizer is 0.02%, the pH is 6, and the organic matter content is 66%.

Abstract

The invention discloses a method for manufacturing carbon and carbon fertilizers by the aid of straw. By the aid of the method, the carbon and the carbon-based active organic fertilizers which are beneficial to crop growth can be manufactured for ratios of soil structures according to characteristics of local soil. The method has the advantages of energy conservation, environmental protection, simplicity in operation, easiness in learning and high biomass comprehensive utilization rate.

Description

technical field [0001] The present invention relates to biochar fertilizer. More specifically, it relates to a method for making charcoal and charcoal fertilizer by using straw. Background technique [0002] Matter is the organic matter produced by plants through photosynthesis. Biomass energy is a kind of solar energy. Biomass is the main absorber and storage of solar energy. As the main components of plant biomass—— lignin and cellulose The regeneration rate of 100 million tons is equivalent to 15-20 times of oil production in terms of energy conversion. If these resources are well utilized, human beings will have an inexhaustible treasure house of resources. Moreover, the CO in the air derived from biomass 2 , CO is produced after combustion 2 , so it does not increase the CO in the air 2 Therefore, biomass is cleaner than mineral energy. [0003] In recent years, the application of biochar in agriculture has become a domestic hot topic, and making biochar into fert...
