Description
Technical Field
The invention relates to the field of agricultural fertilizers, and in particular relates to a cinnamomum longepaniculatum leaf residue fermented organic fertilizer and a preparation method thereof.
Background
The cinnamomum longepaniculatum is a unique species in Sichuan, and cinnamomum longepaniculatum oil extracted from cinnamomum longepaniculatum leaf residues is an important raw material for foreign trade and mass selling and related daily chemical industry. The oil of Cinnamomum camphora contains more than 40 kinds of components, wherein 1, 8-cineole accounts for about 60%, and the product has important antibacterial and antiviral effects, especially has strong effect in preventing coronavirus. However, in recent years, with the increasing production of camphor oil, the accumulation and waste of byproduct camphor leaf residue become more serious, and the harmless treatment of camphor leaf residue is also receiving attention. At present, some workshops and farmers mostly adopt a direct incineration method to treat cinnamomum longepaniculatum leaf residues, so that a large amount of smoke pollution is caused, the emission of carbon dioxide is increased, great hidden dangers are brought to fire safety, and meanwhile, resources are greatly wasted. Researches show that the distilled cinnamomum longepaniculatum leaf residue is a natural pollution-free high-quality organic fertilizer raw material (publication number)CN104306443B) It contains a large amount of high-quality organic matters, nitrogen, phosphorus, potassium and various medium and trace elements; the fermented and decomposed cinnamomum longepaniculatum leaf residue organic fertilizer is rich in humic acid, and has the effects of improving soil, stimulating crop growth, improving the quality of agricultural products and the like. Particularly, the cinnamomum longepaniculatum leaf residues contain various active substances with antibacterial and insecticidal effects, the fertilizer prepared from the cinnamomum longepaniculatum leaf residues can have the special effects of expelling insects and inhibiting soil-borne diseases, is purely natural and pollution-free, and has a positive effect of reducing the application of pesticides. However, the conventional method for preparing the fertilizer by fermenting the cinnamomum longepaniculatum leaf residues directly refers to the conventional organic fertilizer fermentation technology, and although the cinnamomum longepaniculatum leaf residue fertilizer with good fertilizer efficiency can be prepared, the active substances with bacteriostatic and insecticidal effects in the cinnamomum longepaniculatum leaf residues are greatly decomposed and lost due to improper fermentation method, so that the bacteriostatic and insecticidal effects of the obtained cinnamomum longepaniculatum leaf residue fertilizer are far different from the theoretical effects; meanwhile, the cinnamomum longepaniculatum leaf residue has the antibacterial effect, so that the fermentation process is slow, the fermentation degree is low, and the large-scale industrial production and agricultural popularization of cinnamomum longepaniculatum leaf residue fertilizer are seriously influencedThe preparation is used.
Disclosure of Invention
The invention aims to overcome the defects of poor antibacterial and insecticidal effects, slow fermentation speed and longer production period of the conventional cinnamomum longepaniculatum leaf residue fermented fertilizer, and provides the cinnamomum longepaniculatum leaf residue fermented organic fertilizer and the preparation method thereof; meanwhile, by adjusting the fermentation raw materials and the proportion thereof in a targeted manner, the pH values of the fermented fertilizers are different, the requirements of different acid-base soils can be met, the application range of the cinnamomum longepaniculatum leaf residue fermented organic fertilizer is remarkably increased, and the industrial production and agricultural large-scale application of the cinnamomum longepaniculatum leaf residue fermented organic fertilizer are facilitated.
The cinnamomum longepaniculatum leaf residue fermented organic fertilizer is prepared from the following raw materials in parts by weight: 30-50 parts of cinnamomum longepaniculatum leaf residues, 10-40 parts of vinasse, 5-30 parts of cow dung and 0.1-0.2 part of fermentation decomposing agent;
the fermentation decomposition agent is a composite microbial fermentation strain which is screened from the cinnamomum longepaniculatum leaves in a natural composting state through specific culture conditions and screening conditions and can effectively and quickly ferment the cinnamomum longepaniculatum leaf residues, and various microbial fermentation strains contained in the fermentation decomposition agent are less influenced by insecticidal and bacteriostatic substances in the cinnamomum longepaniculatum leaf residues and can effectively cooperate with each other, so that the cinnamomum longepaniculatum leaf residues are quickly and efficiently degraded and fermented, and a large amount of humic acid and organic matters are generated; meanwhile, the optimal growth and fermentation temperature is lower, and the loss of insecticidal and bacteriostatic substances caused by high-temperature fermentation can be avoided, so that the content of the insecticidal and bacteriostatic substances in the cinnamomum longepaniculatum leaf residue fermented organic fertilizer is obviously improved; the culture conditions are that the culture temperature is 50 ℃ and the culture humidity is 65% RH; the screening conditions are as follows: the cinnamomum longepaniculatum leaf residues are used as fermentation raw materials, and the loss amount of the cinnamomum longepaniculatum leaf residues is not less than 5% after the cinnamomum longepaniculatum leaf residues are cultured and fermented for 15 days under the condition that the addition amount of a fermentation decomposition agent is 0.1% by weight.
Wherein, preferably, the preparation method of the fermentation decomposing inoculant comprises the following steps:
(1) selecting a cinnamomum longepaniculatum leaf compost sample in a high-temperature fermentation period under a natural composting state; placing the sample in a container, adding 10 times of water by weight, placing the sample on a shaker, and treating the sample for 10 minutes under the condition of 200 revolutions per minute; standing for 20 minutes, taking supernatant, and separating and drying the supernatant to obtain a fermentation decomposing agent sample;
(2) adding a fermentation decomposition agent sample into a culture dish filled with the cinnamomum longepaniculatum leaf residues according to the addition amount of 0.1 wt%, placing the culture dish in a constant-temperature incubator with the temperature of 50 ℃ and the humidity of 65% RH for culturing for 15 days, placing the culture dish in a constant-temperature drying oven for drying at 105 ℃ for two hours, cooling, and weighing to calculate the weight loss rate of the cinnamomum longepaniculatum leaf residues;
(3) when the calculated weight loss rate is not lower than 5%, the fermentation decomposing agent sample is the required fermentation decomposing agent; and when the calculated weight loss rate is lower than 5%, selecting the sassafras leaves residue compost sample in a high-temperature fermentation period under the natural composting state of different places to repeat the steps.
Further, in order to achieve the purpose, the invention also provides a preparation method of the cinnamomum longepaniculatum leaf residue fermented organic fertilizer, which comprises the following process steps:
(1) crushing cinnamomum longepaniculatum leaf residues, adding raw materials according to a formula, and uniformly mixing to obtain a mixture;
(2) adjusting the water content of the mixture to 55-65%, and performing composting fermentation treatment; controlling the fermentation temperature to be not higher than 65 ℃ in the compost fermentation treatment process;
