Embodiment Construction

[0010] A preparation method of vegetable organic fertilizer has the following steps:

[0011] 1. Extract wood vinegar: select hard broad-leaved xylem, cut into square forest sections with a width of 40-80mm and a length of 500-600mm, dehydrate by microwave, the content is between 4% and 18%, and put them into flue gas In the carbonization pyrolysis furnace, anhydrous air is used to supply oxygen in the furnace, and micro-oxygen combustion is carried out. The temperature in the furnace is controlled at 150 0 C~350 0 Between C, the volatiles released from pyrolysis are separated by an adjustable recombination separator, and the separated volatiles are sent to a cooler for cooling to collect condensable liquid, that is, wood vinegar, and the cooling temperature is at 20 0 C~80 0 Between C, there is no pH value detection port in the liquid collection pipe, and when the liquid pH value reaches 4~6, the collection is terminated;

[0012] 2. Aggregation and separation: put wood vi...

Abstract

The invention discloses a preparation method for a vegetable organic fertilizer. The method is characterized by comprising the following steps: 1) extracting a wood vinegar liquid; 2) performing aggregating separation; 3) performing adsorption separation; and 4) filtering a finished product: taking out traditional Chinese herbal medicine residues in the wood vinegar liquid after standing, and performing filtration by using fine filter paper, so as to obtain the vegetable organic fertilizer. The method provided by the invention has the following advantages: the method can improve the dry matteraccumulation amount and the chlorophyll content of vegetables, maintains the soil fertility and balance of the microorganism environment, and is an agricultural fertilizer suitable for health, safetyand environmental protection.

Description

technical field [0001] The invention relates to cultivation techniques, in particular to a vegetable organic fertilizer and a preparation method thereof. Background technique [0002] With my country's reform and opening up and economic development, my country's animal husbandry has developed rapidly, greatly improving and enriching the "vegetable basket" of citizens and improving the living standards of the people. Untreated livestock and poultry excrement and waste water directly flow into rivers and lakes, causing a large amount of nitrogen and phosphorus loss, causing water pollution and eutrophication, and destroying the natural ecological environment; There is a large amount of land, and a large amount of malodorous substances and nitrates will be produced during the stacking, which will pollute the atmosphere and groundwater. In rainy days, the sewage overflows, which often causes great dissatisfaction among nearby residents. Unlike other industrial pollutants, lives...
