The application discloses a kind of for decomposing forest litter composite microbial inoculant, preparation method and its application method, it is related to litter decomposition technical field.The application includes a kind of for decomposing forest litter composite microbial inoculant preparation method, comprising the following steps: S1.to Phanerochaete chrysosporium, Trichoderma reesei and ropegillus catenulatum are respectively carried out directional metabolism preactivation;S2.the three preactivation wet bacteria bodies obtained in step S1 are mixed according to the fresh weight ratio of Phanerochaete chrysosporium:Trichoderma reesei:ropegillus catenulatum 3:2:1, obtain mixed bacteria body;S3.mixed bacteria body is mixed with the straw carrier that is preprocessed by steam explosion according to the mass ratio of bacteria body fresh weight:carrier dry weight 1:2, under the condition of temperature 28 DEG C, relative humidity 92~95%, stationary culture 72 hours, carry out phased micro-perturbation aeration, construct physical symbiosis;S4.the material obtained in step S3 is dried to 15% moisture content at 40 DEG C, obtain composite microbial inoculant;Efficient and stable decomposition of pine forest litter is realized.

The application discloses a device and method for monitoring forest litter decomposition rate, which comprises a sealed monitoring container, an internal sampling part for placing litter samples, and integrated gas concentration sensors, carbon dioxide sensors and carbon removal modules with carbon removal functions. The carbon removal module is connected with a weighing module for monitoring the carbon dioxide absorption amount through mass change. The application realizes quantitative evaluation of the litter decomposition process by real-time collection of dynamic changes of gas concentration in the monitoring space, combination of temperature and humidity environmental factors, and use of a decomposition rate correlation model constructed based on the principle of microbial metabolism. Compared with the traditional mass difference method, the application can effectively shield external environmental interference, realize in-situ, high-frequency and accurate real-time monitoring, and provide scientific data support for forest ecosystem carbon cycle research.

The present application belongs to the technical field of plant litter treatment device, and provides a litter decomposition and compaction treatment device. The litter decomposition and compaction treatment device comprises a barrel part, a compaction part and a centrifugal part. The barrel part comprises a main barrel and a rotating inner barrel. The rotating inner barrel is rotatably installed in the main barrel. The compaction part comprises a support group frame, a compaction block and a support slide rail. The support slide rail is installed in the rotating inner barrel at not less than one place. One end of the support group frame is installed on the support slide rail. The centrifugal part is installed in the barrel part, wherein the centrifugal part comprises a centrifugal drum. The other end of the support group frame is installed on the centrifugal drum and is in transmission connection with the rotating inner barrel. Litter is placed in the centrifugal drum, and the compaction block is placed on the surface layer of the litter, and the compaction block is located in the centrifugal drum. The treatment device can be used on a wider range of soil.

The present application relates to the technical field of biological agent preparation, and particularly relates to a biological agent for accelerating litter decomposition and improving soil fertility, a preparation method and application thereof.The biological agent comprises 20-35 parts of microbial inoculum, 15-25 parts of humus, 10-18 parts of porous carrier, 3-8 parts of citric acid chelate salt and 2-5 parts of slow-release agent.The biological agent prepared according to the components of the present application can degrade the content of cellulose, hemicellulose and lignin in litter, and improve the content of organic matter, total nitrogen, total potassium and available phosphorus in soil, thereby providing a basis for effective degradation of litter.
