Embodiment 1

[0045] Step 1 Garbage disposal in meat processing plants

[0046] The drained cooked meat was chopped into meat strips with a length of 1.7 cm; the hair in the garbage was soaked in an aqueous solution of keratinase, and enzymatically hydrolyzed at 50° C. for 2.4 hours.

[0047] Step 2 prepare the maintenance agent

[0048] Then mix the mixture 1 with the mixed starter in a mass ratio of 100:4; after mixing evenly, put it in a fermenter, and ferment in a sealed manner at 29°C for 9 days.

[0049] Step 3 Conservation of saline-alkali land

[0050] The plowing depth is 5cm; the application rate of the conservation agent is 72kg / mu.

[0051] After the saline-alkali land is conserved by the above method, the total nitrogen content of the saline-alkali land is 0.29g / kg; the total phosphorus content is 20.96 μg / g; the total potassium content is 96.26 μg / g; the pH is reduced to 7.8; ; Alkalinity decreased to 20.8%.

Embodiment 2

[0053] Step 1 Garbage disposal in meat processing plants

[0054] The drained cooked meat was chopped into meat strips with a length of 1.8 cm; the hair in the garbage was soaked in an aqueous solution of keratinase, and enzymatically hydrolyzed at 55° C. for 2.5 hours.

[0055] Step 2 prepare the maintenance agent

[0056] Then mix the mixture one with the mixed starter in a mass ratio of 100:3; after mixing evenly, put it in a fermenter, and ferment in a sealed condition at 30°C for 10 days.

[0057] Step 3 Conservation of saline-alkali land

[0058] The plowing depth is 3cm; the application rate of the conservation agent is 68kg / mu.

[0059] After the saline-alkali land is conserved by the above method, the total nitrogen content of the saline-alkali land is 0.30g / kg; the total phosphorus content is 22.18 μg / g; the total potassium content is 97.45 μg / g; the pH is reduced to 7.7; ; Alkalinity decreased to 20.2%.

Embodiment 3

[0061] Step 1 Garbage disposal in meat processing plants

[0062] The drained cooked meat was chopped into 2 cm long meat strips; the hair in the garbage was soaked in an aqueous keratinase solution, and enzymatically hydrolyzed at 52°C for 2.6 hours.

[0063] Step 2 prepare the maintenance agent

[0064] Then mix the mixture one with the mixed starter in a mass ratio of 100:5; after mixing evenly, put it in a fermenter, and ferment for 9 days in a sealed condition at 32°C.

[0065] Step 3 Conservation of saline-alkali land

[0066] The plowing depth is 4cm; the application rate of the conservation agent is 73kg / mu.

[0067] After the saline-alkali land is conserved by the above method, the total nitrogen content of the saline-alkali land is 0.32g / kg; the total phosphorus content is 22.54μg / g; the total potassium content is 98.16μg / g; the pH is reduced to 7.5; ; Alkalinity decreased to 19.6%.

[0068] The data of each index of described saline-alkali land soil is shown in ...

Abstract

The invention is applicable to the technical field of saline and alkaline land cultivating, and provides a method for cultivating a saline and alkaline land by utilizing garbage of a meat processing factory. The method comprises the following steps of separating the garbage of the meat processing factory, mixing with excrements of livestocks of the meat processing factory, wood vinegar, humic acidand wood charcoal, sterilizing after mixing, and fermenting to obtain a cultivating agent; uniformly scattering the cultivating agent onto the deep ploughing saline and alkaline land, irrigating, andplanting plants. Therefore, by using the garbage of the meat processing factory for cultivating the saline and alkaline land, so that the nutrient contents of the soil of the saline and alkaline landcan be improved, and the pollution of the garbage of the meat processing factory on the environment is reduced.

Description

technical field [0001] The invention relates to the technical field of saline-alkali land conservation, in particular to a method for using meat factory garbage to conserve saline-alkali land. Background technique [0002] With the rapid development of urban and rural breeding and aquaculture, the number of meat processing plants is increasing, accompanied by a large amount of waste from meat processing plants, mainly leftovers, bones, hair, etc. of livestock and poultry meat, and a large amount of livestock Poultry manure, these garbage accumulates in large quantities, breeds germs, causes serious pollution to the atmosphere, soil and water environment, and often causes great troubles to residents living nearby. [0003] The salt content in the saline-alkali soil is high, and the soil is prone to compaction, resulting in smaller soil porosity, poor soil air permeability and water permeability, seriously affecting the metabolism of microorganisms in the soil, reducing the ac...
