Abstract

The present invention discloses an organic liquid fertilizer and its preparation method. It utilizes the molasses produced in production process of white granulated sugar as main raw material, and makes it undergo a series of steps of dilution, filtration, pH value regulation, fermentation and pasteurization to obtain the invented final product richly containing the elements of nitrogen, phosphorus and potassium, etc.

Description

A kind of organic liquid fertilizer and preparation method thereof
Technical field
The invention belongs to the chemical fertilizers production technical field, be specifically related to a kind of organic liquid fertilizer and preparation method thereof.
Background technology
China is large agricultural country, and since ancient times, fertilizer is fertile as the basis of agricultural and forestry production always.But along with the fast development of plant husbandry, use chemical fertilizer easy quick-acting, can increase production the common recognition that becomes a lot of people gradually fast.But the life-time service of chemical fertilizer can cause consuming excessively with soil fertility of a large amount of Nonrenewable energy resources to be failed.In order to deal with this situation, people have to strengthen fertilizer amount gradually, and form vicious cycle, thereby cause serious day by day ecotope negative effect, and it is bad that the physico-chemical property of soil becomes.Present stage, soil acidification, harden, farm crop chemical fertilizer residual quantity problem such as exceed standard is seen in report often, and these problems become the bottleneck of the restriction national economic development gradually.And existing solid organic fertilizer not only total nutrient content is lower, fertilizer efficiency can not show a candle to inorganic fertilizer.Simultaneously,, contain a large amount of pathogenic micro-organisms,, very likely cause secondary pollution if sterilization is not thorough because its raw material sources are mainly feces of livestock and poultry and stalk.
It should be noted that in the sugar industry production process to produce the surprising waste of quantity, as waste molasses.These wastes can cause severe contamination to water source and surrounding environment if not adding just to handle directly discharges.Though and also be no lack of the method for processing in the prior art, exist all that energy consumption is big, working cost is high, administer and thoroughly, easily do not cause secondary pollution problems.But then, contain a large amount of available resources in these wastes again.With the waste molasses is example, wherein just contains abundant organism, protein and nitrogen sulphur compounds.These resources then will produce far-reaching influence in economic and social aspect if can be converted into the raw material of organic fertilizer production.Therefore, how to improve the fertilizer efficiency utilization ratio of organic fertilizer, realize the comprehensive utilization of waste molasses, just become the technical problem that needs to be resolved hurrily in the prior art.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, with waste molasses as main production raw material, provide a kind of fertilizer efficiency remarkable, safe in utilization, and can improve Soil structure organic liquid fertilizer.
Another object of the present invention provides the preparation method of described organic liquid fertilizer.
Purpose of the present invention is achieved by the following technical programs.
Organic liquid fertilizer of the present invention is made up of the raw material of following weight parts: 10～30 parts of waste molasses, 0.3～1 part in ammonium sulfate, 4～4.5 parts in urea, 3～8 parts of monoammonium phosphates, 4～8 parts of vitriolate of tartar, 50～70 parts in water, 0.1～0.2 part in sulfuric acid.
Become the method for organic liquid fertilizer to form by following steps successively the feedstock production of above-mentioned weight part:
(1) waste molasses is placed in the fermentor tank with the clear water dilution, filter, add sulfuric acid, regulate pH value to 4.5～5.0;
(2) sealed fermenting jar is heated while stirring to 20 ℃～30 ℃;
(3) stir after 2～3 days, treat that pot liquid begins to stop heating when spontaneous fermentation heats up, when temperature in the jar reaches 35 ℃～40 ℃, open and jar add an ammonium sulfate, and then airtight stirring 2～3 days;
(4) open jar, add urea, monoammonium phosphate and vitriolate of tartar successively, airtight stirring 1～2 day is after the sterilization of crust formula promptly obtains organic liquid fertilizer.
In the process of the described heating while stirring of step 2, use air compressor machine to carry out not intermittent aeration processing, the air of feeding is handled through activated carbon canister and is filtered.
In the described airtight once more whipping process of step 3, use air compressor machine to carry out not intermittent aeration processing, the air of feeding is handled through activated carbon canister and is filtered.
The present invention has following advantage with respect to prior art: 1, for farm crop provide full nutrition, promote plant growth.Elements such as the nitrogen that it was rich in, phosphorus, potassium can promote beneficial microorganism breeding in the soil, strengthen soil water-reataining fertilizer-keeping ability and metabolic ability, improve the soil organism that causes because of " predation formula " planting patterns effectively and run off.2, utilize the waste molasses that produces in the white sugar production process as main raw material, both reduced the exhaust emission in the Closed Circulation in Sugar Production, increased the added value that sugar-refining industry is produced simultaneously, product safety is reliable.3, use with respect to solid fertilizer convenient, be used with chemical fertilizer can emergency help mutually, complementary short long.4, technology is easy, with low cost, has remarkable economical, ecology and social benefit.
The present invention detects through Yunnan Academy of Agricultural Sciences, and detected result sees Table 1.
