Problems solved by technology

With the development of the fruit planting and processing industry, the production of pomace has increased significantly. Pomace is a by-product obtained from the process of fruit juice or canned production. It can produce 300-500kg of fresh pomace and 120-165kg of dried pomace after drying. There are about tens of millions of tons of pomace resources in the country every year. Fruit and vegetable pomace contain a large amount of nitrogen, phosphorus, potassium, organic matter, humic acid and other substances. However, there is still a lack of effective means for the comprehensive...

Abstract

The invention relates to an organic fertilizer prepared by fermentation of fruit and vegetable slag and production technology thereof, belonging to the technical field of organic fertilizers. The raw materials of the organic fertilizer comprise, by weight, 400 to 1000 parts of one or more selected from the group consisting of apple slag, pear slag and vegetable slag, 600 to 1800 parts of sludge, 500 to 1000 parts of livestock manure and 0.5 to 1.5 parts of an activator. The production technology comprises the following steps: (1) respectively taking the above-mentioned raw materials according to desired parts and evenly mixing the raw materials; (2) piling the mixed raw materials into a certain shape or putting the mixed raw materials into a fermenting tank for fermentation; (3) evenly overturning the fermenting raw materials every 40 to 50 hours and overturning three to four times so as to obtain the bio-fertilizer after the fermentation is finished. The advantages of the invention are as follows: the waste things are turned into the valuable; the obtained bio-fertilizer is rich in nutriments, has high fertilizer efficiency, and enables environmental pollution resulted from the deterioration and decay of fruit and vegetable slag to be avoided.

Example Embodiment

[0029] Example 1
[0030] The fruit and vegetable residue fermented organic fertilizer of this embodiment includes the following raw materials by weight: 300 parts of apple pomace (40% moisture by mass, 6.5% by mass ash), and 300 pear residue (38% by mass of moisture and 6.8% by ash). Servings, vegetable residue (water mass percentage 41%, ash mass percentage 6.1%) 300 parts, sludge (moisture mass percentage 80%) 1000 parts, livestock manure (moisture mass percentage 15%, ash mass percentage 2%) 500 parts , 0.5 parts of activator.

Example Embodiment

[0031] Example 2
[0032] The fruit and vegetable residue fermented organic fertilizer of this embodiment includes the following raw materials by weight: apple pomace (water mass percentage 38%, ash mass percentage 6.6%) 500 parts, vegetable residue (moisture mass percentage 40%, ash mass percentage 5.8%) 400 Parts, 1500 parts of sludge (73% moisture mass percentage), 800 parts of livestock and poultry manure (12% moisture mass percentage, 1.5% ash mass percentage), 1 part activator.

Example Embodiment

[0033] Example 3
[0034] The fermented organic fertilizer of fruit and vegetable residue in this embodiment includes the following raw materials by weight: vegetable residue (water mass percentage 44%, ash mass percentage 5.5%) 1,000 parts, sludge (water mass percentage 87%) 600 parts, livestock manure ( The water content is 18%, the ash content is 2.5%) 1000 parts, and the activator is 1.5 parts.
[0035] The activator used in the above embodiment is a special activator for organic fertilizer produced by Beijing Biotechnology Co., Ltd. It is a product of living microorganisms in the state of spores, and is mainly composed of filamentous bacteria, yeasts, bacteria, and actinomycetes. A variety of natural beneficial microbial flora coexisting with both sexual and conditional anaerobicity. The mass content of each species is: filamentous bacteria 15-35%, yeast 15-35%, bacteria 15-35%, actinomycetes 15-35%.
[0036] The production process of the fruit and vegetable residue fermented organic fertilizer of the foregoing embodiment includes the following steps:
[0037] 1. Take fruit residue or vegetable residue or fruit residue and vegetable residue, sludge, livestock and poultry manure, and activator according to the required number of portions, and mix them evenly.
[0038] 2. Pile up the mixed raw materials to form or send them into the fermentation tank for fermentation, insert the long-wire thermometer into the pile of materials to be fermented, and observe the temperature changes. The exposed parts of the materials to be fermented shall be waterproof and insulated.
[0039] 3. The raw materials in the fermentation period are evenly tipped over every 40-50 hours, and the number of tippings is controlled 3-4 times to complete the fermentation into biological fertilizer.
[0040] The law of temperature change in the pile to be fermented during the fermentation process is as follows: (the temperature changes slightly in different seasons)
[0041] Day 1: The temperature in the fermented material pile is about 5-10 degrees higher than the ambient temperature at that time.
[0042] The second day: The temperature in the fermentation material pile rises to about 35-45 degrees.
[0043] Day 3: The temperature in the fermentation material pile rises to about 50-55 degrees.
[0044] Day 4: The temperature in the fermented material pile rises to about 60-65 degrees.
[0045] Day 5: The temperature in the fermentation material pile rises to about 65-75 degrees.
[0046] Sixth day: The temperature in the fermentation material pile rises to about 75-78 degrees.
[0047] Day 7: The temperature in the fermentation material pile is about 78-75 degrees.
[0048] The fermentation period is generally 7-8 days. During the fermentation, the thermometer shows the temperature from low to high, indicating that the activator is activated and working. After the fermentation period, the materials basically have no foul smell, are scattered and not sticky. The color is dark brown, and the moisture content is about 20-35%.
[0049] The fruit and vegetable residue fermented organic fertilizer of the present invention has done comparative experiments with compound fertilizers, ordinary organic fertilizers, and inorganic fertilizers. They have been applied to the same crops at the same growth period. The comparison of farmland experiments proves that the effect of increasing crop yields reaches 10-23%. The above is significantly higher than the comparison fertilizer, the specific experimental comparison:
[0050]
[0051] In the above table, ordinary organic fertilizers are organic materials containing more than 28% organic matter, such as stalk materials, plant ash, etc.; inorganic fertilizers are urea, diamine, etc.; compound fertilizers are mixed fertilizers of the above ordinary organic fertilizers and inorganic fertilizers.
[0052] In order to show the actual effect of the present invention, an experiment and comparison were carried out.
[0053] The statistics are as follows:
[0054]
[0055]
[0056] In the above table, ordinary organic fertilizers are organic materials containing more than 28% organic matter, such as stalk materials, plant ash, etc.; inorganic fertilizers are urea, diamine, etc.; compound fertilizers are mixed fertilizers of the above ordinary organic fertilizers and inorganic fertilizers.
[0057] Tests have proved that the fruit and vegetable residue fermented organic fertilizer of the above-mentioned embodiment of the present invention decomposes many organic matter into organic colloids by the action of microorganisms, greatly increases the soil adsorption capacity, and produces a lot of sticky matter, which makes the soil particles become cemented. The stable aggregate structure improves soil water retention, fertilizer retention and air permeability, and improves the soil's ability to regulate temperature.
[0058] The fermented organic fertilizer with fruit and vegetable residues in the above embodiments of the present invention contains a large number of active enzymes secreted by the digestive tract of animals and various enzymes produced by microorganisms in the added livestock and poultry manure. After these substances are applied to the soil, the soil The large number of microorganisms multiplies and produces many beneficial microorganisms, such as nitrogen-fixing bacteria, ammonifying bacteria, cellulose decomposing bacteria, nitrifying bacteria, etc., which can greatly improve the soil enzyme activity and biological reproduction and transformation ability, thereby improving the soil absorption performance and buffering performance And stress resistance, it solves the problems of soil compaction and high nitrate content caused by long-term application of inorganic fertilizer.
