Embodiment 1

[0030] Embodiment 1: a kind of preparation method of preventing and treating root rot functional biochar-based nutrient matrix,

[0031] (1) Preparation of carbonized material: After the agricultural and forestry wastes are crushed, pass through a 10-mesh sieve, and then put into the atmosphere furnace. After the atmosphere furnace is evacuated, nitrogen gas is introduced to start low-temperature baking; the atmosphere furnace is set at a rate of 15°C / min. The temperature was raised to 480°C, and after the temperature was raised to the highest temperature, the high temperature was maintained for 800 minutes; the heating was stopped, and the temperature was naturally lowered to room temperature to obtain carbonized agricultural and forestry waste. (2) Preparation of functional biochar-based nutrient matrix for preventing and controlling root rot: adding 10 parts by weight of the agricultural and forestry waste charcoal material obtained in step (1) to Trichoderma aculeatus CGM-1...

Embodiment 2

[0032] Embodiment 2: The similarities between this embodiment and Embodiment 1 will not be repeated, the difference is: the preparation of the functional biochar-based nutrient matrix for the prevention and treatment of root rot: add 15 parts by weight of the carbonized material obtained in step (1) to Patent strain Trichoderma aculeatus CGM-10 (preservation number: CCTCC No. M 2014001) spore powder with bio-control function 0.5 parts by weight, Trametes trichosanthes SEM-6 (preservation number is CCTCC No. M 2014002) bacteria liquid 15 parts by weight and 5 parts by weight of humic acid, 20 parts by weight of municipal dried sludge, and 25 parts by weight of dried biogas residue, mixed evenly and dried at low temperature (below 50°C) to a water content below 30% to obtain the functionality of preventing and controlling root rot Biochar-based nutrient matrix, which is used as biochar-based nutrient soil for municipal greening, has a control effect of 95-98% on root rot of Euony...

Embodiment 3

[0033] Embodiment 3: The similarities between this embodiment and Embodiment 1 will not be repeated, the difference lies in: the preparation of the functional biochar-based nutrient matrix for the prevention and treatment of root rot: add 30 parts by weight of the carbonized material obtained in step (1) to Patent strain Trichoderma aculeatus CGM-10 (preservation number: CCTCC No. M 2014001) spore powder 1 weight part with biocontrol function, 20 weight parts Trametes trichosanthes SEM-6 (preservation number is CCTCC No. M 2014002) bacterial solution parts, and 10 parts by weight of humic acid, 50 parts by weight of municipal dried sludge, 50 parts by weight of dried biogas residue, and 10 parts by weight of plant ash were mixed evenly and dried at low temperature (below 50°C) until the water content was below 30%. The functional biochar-based nutrient matrix for root rot is used as a biochar-based nutrient soil for lawn planting, and its control effect on grass root rot reache...

Abstract

The invention discloses a functional biochar-based nutrition medium for preventing and treating a root rot and a preparation method. The functional biochar-based nutrition medium is characterized by being prepared from the following components in parts by weight: 10-30 parts of a forestry and agricultural waste carbonized material, 0.1-1 part of trichoderma asperellum CGM-10 conidial powder of which the preservation number is CCTCC No. M 2014001, 10-20 parts of a trametes trogii SEM-6 bacteria solution of which the preservation number is CCTCC No. M 2014002, 0-10 parts of humic acid, 0-50 parts of municipal dry sludge, 0-50 parts of dry biogas residue and 0-20 parts of plant ash; and the components are mixed evenly and baked until the moisture content is 20-30% to obtain the functional biochar-based nutrition medium for preventing and treating the root rot. The functional biochar-based nutrition medium has the effects of obviously promoting plant growth and improving the performance of soil, can be used as a fertilizer, a nutrient medium, nutrient soil and the like, and has wide application value in the aspect of agricultural crop planting.

Description

technical field [0001] The invention relates to the field of biotechnology, in particular to a functional biochar-based nutrient matrix for preventing and controlling root rot and a preparation method thereof. Background technique [0002] According to statistics, the annual output of agricultural and forestry waste (straw, furfural residue, xylose residue, wood chips, etc.) in my country has exceeded 1 billion tons, accounting for more than 90% of the total organic waste in China. Due to the difficulty of utilization, most of them are discarded at will or even burned in the open air, causing pollution to the atmosphere, water system and soil, which has seriously threatened the national ecological environment and sustainable development. People have explored the resource utilization of agricultural and forestry waste in many aspects. At present, technologies such as the preparation of cellulosic ethanol, bio-based materials and biogas have appeared, but there are still probl...
