Description
Technical field
The present invention relates to the method that a kind of orientation fermentation organic waste prepares acid organic fertilizer, the pH value of this acidity organic fertilizer is about 6.5, the improvement in saltings is had more advantage, also is very suitable for liking the cultivation of sour crop such as part flowers, nursery stock, tealeaves, fruit tree etc. than common fertilizer, belong to biological technical field.
Background technology
Fertilizer promote plant growth, improve the soil, aspect such as culture fertility has vital role.Utilize town and country organic waste processing fertilizers such as fowl and animal excrement, agricultural crop straw, dry branches and fallen leaves, kitchen are surplus, food-processing waste material can reach the purpose that turns waste into wealth, eliminates organic contamination source, resource circulation utilization, development low-carbon economy.
The existing salinization in various degree of China nearly 500,000,000 mu of needs of ploughing are transformed before having statistics table to make eye bright, and application of organic fertilizers is one of important modification measures.But, the fertilizer of aerobic composting fermentation technology output commonly used all is a meta-alkalescence at present, its pH value often is higher than 8.0, even up to more than 9.0, and in the aerobic composting fermentation process, the pH value of material easily makes the nitrogen in the material volatilize with the form of ammonia usually above 7.0, has reduced the content of nitrogen nutrient in the fertilizer.This alkalescent fertilizer not as acid fertilizer, is not suitable for liking the plantation of sour crop such as part flowers, nursery stock, tealeaves, fruit tree to the improved effect in saltings yet.
There is the investigator to report the manufacturing and the effect of acid organic fertilizer.Guo Xiaohua etc. have carried out " effect comparison of acid fertilizer improvement geavy salt alkali " test; Chinese patent " a kind of saline-alkali soil conditioner and preparation method thereof " (ZL00100436.0) discloses a kind of method that is prepared saline-alkali soil modifying agent by 14 kinds of organic acids such as citric acid; Chinese patent " a kind of saline-alkali land improving and fertilizing agent and preparation method thereof " (ZL200510001737. 6) discloses a kind of method that is prepared saline-alkali land improving and fertilizing agent by the fermentation of composite microbial bacteria liquid sealing based on the organic substance of dregs of beans; Chinese patent " a kind of preparation method of fertilizer dedicated to alkaline land " (200610083425.9) discloses and has a kind ofly formed acid organism by the saccharomycetes to make fermentation grouts, adds the method that is prepared fertilizer dedicated to alkaline land by the nitro humic acid of weathered coal or brown coal manufacturing again; Chinese patent " a kind of organic biofertilizer prepared through closed anaerobic fermentation " (200710111509.3) discloses that a kind of (ratio is: 7-8:0.5-1.5:1.5-2.5) prepare the method for biological organic fertilizer, but the fertilizer of undeclared preparation is a tart by the totally-enclosed anaerobically fermenting domestic refuse of HM bacterial classification, fowl and animal excrement, agricultural crop straw.Above-mentioned report and patent show that acid fertilizer has good result to the improvement saltings; Adopted high price organic raw material such as grouts to make the ability to bear of product cost in the above-mentioned patent far above the user, adopted the nitro humic acid made from non-renewable weathered coal or brown coal, adopt organic acids such as very high industrial product of price such as citric acid, adopted the domestic waste raw material that can not be used for agriculture production.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of acid organic fertilizer, the pH value of this acidity organic fertilizer is about 6.5, its acidity is owing to directed anaerobically fermenting produces, to alkaline land improving than common fertilizer have more advantage, also be very suitable for liking the cultivation of sour crop such as part flowers, nursery stock, tealeaves, fruit tree etc., possess continuous cropping soil carried out the effect of little restoration of the ecosystem and cheap simultaneously.
