Problems solved by technology

However, the traditional composting method has a long cycle and low efficiency. The volatilization of ammonia and the release of hydrogen sulfide and other gases during the fermentation process will cause serious environmental pollution. At the same time, there are also shortcomings such as low efficiency of finished fertilizers. cycle, improve the quality of compost, make the composted agricultural and forestry waste meet the requirements of soilless culture substrate, and partially or completely replace peat for soilless cultivation

Embodiment 1

[0058] 1. Pretreatment of agricultural and forestry waste raw materials

[0059] 1) Use a pulverizer (Beijing Zhongyi Shenlong Machinery Co., Ltd.) to pulverize garden waste branches (twigs pruned from willows, pagoda trees, poplars, etc.) into particles with a particle size of ≤ 1 cm to obtain waste particles. At the same time, the organic carbon content and nitrogen content of the waste particles were measured, and the results are shown in Table 1.

[0060] Determination of the nitrogen content of waste particles by the Kjeldahl method;

[0061] Potassium dichromate volumetric method-external heating method is used to measure the organic carbon content in the cultivation mixed substrate. The specific measurement method is as follows: After adding the air-dried cultivation mixed substrate into the dry hard test tube, add K 2 Cr 2 o 7 Standard solution and concentrated H 2 SO 4 , then put the test tube at 170-180°C to boil the liquid in the test tube for 5 minutes, then p...

[0091] 1. Pretreatment of agricultural and forestry waste raw materials

[0092] 1) Using a pulverizer to crush corncobs into particles with a length of 0.5-1.5 cm to obtain waste particles, and simultaneously measure the organic carbon content and nitrogen content of the waste particles, and the results are shown in Table 1.

[0093] 2) Add urea to the corn cob granules, adjust the C / N ratio of the corn cob granules to 27, and make fermented compost corn cob granules, wherein 0.813 kg of urea is added to every 100 kg of waste granules (dry weight).

[0094] 2. Prepare fermentation additive dilution

[0095] Add bamboo vinegar liquid to water, mix uniformly, be mixed with bamboo vinegar liquid dilution (being fermentation additive dilution) for subsequent use, wherein the volume ratio of bamboo vinegar liquid and water is 1: 800, and the pH value of bamboo vinegar liquid is 2, The density is 1.5g / ml, the organic acid content is 11%, and the phenolic compound content is 8%.

Embodiment 3

[0106] 1. Pretreatment of agricultural and forestry waste raw materials

[0107] 1) Using agricultural waste rice husk as raw material, the organic carbon content and nitrogen content of agricultural waste rice husk were measured, and the results are shown in Table 1.

[0108] 2) Add urea to the waste granules, adjust the C / N ratio of the waste granules to 30, and prepare fermented compost granules, wherein 1.473 kg of urea is added to every 100 kg of waste granules (dry weight).

[0109] 2. Prepare fermentation additive dilution

[0110] Add wood vinegar to water, mix well, be mixed with wood vinegar dilution (i.e. fermentation additive dilution) for subsequent use, wherein the volume ratio of wood vinegar and water is 1: 1500, and the pH value of wood vinegar is 3.2, The density is 1.0g / ml, the organic acid content is 7%, and the phenolic compound content is 7%. .

[0111] 3. Fermentation stacking treatment

[0112] 1) Add fermentation bacteria agent organic waste fermen...

Abstract

The invention discloses a mixed plant culture medium and a preparation method thereof. The culture medium comprises peat and an agricultural and forest residue compositing fermentation medium, wherein the volume proportion of peat to agricultural and forest residue compositing fermentation medium is (30-50):(50-70). The mixed culture medium prepared by the method in the invention has the advantages of balanced nutrition, high nutrition component contents and stable physical property. The mixed culture medium prepared by the method in the invention is reasonable in nutrition structure and convenient for absorption of foliage plants and meets the growth requirement of the foliage plants, thereby improving the culture survival rate and viewing effect of the foliage plants.

Description

technical field [0001] The invention relates to a nutrient substrate for plant cultivation, in particular to a nutrient substrate for soilless cultivation of foliage plants. Background technique [0002] Substrate cultivation is the main direction of the development of soilless cultivation in my country, and peat, as an ideal soilless cultivation substrate, can be widely used in flower cultivation, factory seedling cultivation of vegetables and seedlings, roof greening, soil improvement and organic fertilizer manufacturing and other processes middle. Substrate is the basis of soilless substrate cultivation, while soilless cultivation is the main cultivation method of facility cultivation. With the adjustment of my country's planting industry structure and the construction of a new socialist countryside, the flower, vegetable and other industries are changing from traditional individual forms to modernization, factoryization, scale, and marketization. Substrate cultivation ha...
