Problems solved by technology

[0004] Fresh waste such as vegetable leaves, vegetable heads and tails, fruit peels, and fruit stones in food waste can be used as raw materials for making agricultural enzymes. However, the composition of food waste is relatively complex, including high-salt and high-oily substances, and it generally needs to be fermented before fermentation. Carry out desalination and fat reduction treatment, otherwise it will easily lead to excessive acidification, inhibit the growth of microorganisms, and is not conducive to the continuous and stable degradation of food waste

Embodiment 1

[0034] In the present embodiment, a kind of method utilizing food waste to make agricultural enzyme comprises the steps:

[0035] Step 1: Preparation of fermentation accessories:

[0036] The proportioning of each component of the fermentation stock solution by mass percentage is as follows:

[0037] 2 parts of brown sugar, 20 parts of tap water, 6 parts of kitchen waste, 1-2 parts of baking powder;

[0038] Among them, food waste includes all kinds of vegetable scraps and edible meat removed from the kitchen, as well as vegetables, rice, meat and other substances left on the dining table and bowls. Food waste contains oil and salt; baking powder contains lactic acid bacteria and yeast Bacterial flora;

[0039] Rinse the food waste with clean water, desalinate and reduce fat, mix the food waste evenly, and crush it into 10-20mm pieces to obtain a food waste mixture;

[0040] Step 2: Add the above-mentioned tap water into the fermentation barrel, add it to the enzyme barrel,...

Embodiment 2

[0047] This embodiment is basically the same as Embodiment 1, especially in that:

[0048] The agricultural enzyme prepared by the method of this embodiment was diluted 100 times and applied between the rows of small green vegetables. See Table 1-3.

Embodiment 3

[0050] This embodiment is basically the same as the previous embodiment, and the special features are:

[0051] The agricultural enzyme prepared by the method of this embodiment was diluted 200 times and applied between the rows of small green vegetables. See Table 1-3.

[0052] Experimental test analysis:

[0053] After the above-mentioned embodiment 1,2,3, agricultural enzymes are used to irrigate the small green vegetables, and the growth conditions of the small green vegetables are compared as follows:

[0054] Table 1. Plant height of pakchoi under different concentrations of enzymes

[0055]

[0056] After the small green vegetables were irrigated with agricultural enzymes in Examples 1, 2, and 3, the soil available nutrients were compared as follows:

[0057] Table 2. Soil available nutrients under different concentrations of enzymes

[0058]

Abstract

The invention discloses a method for preparing an agricultural enzyme from kitchen waste, the prepared agricultural enzyme and application of the agricultural enzyme. The preparation method comprises the following steps: collecting the kitchen waste, crushing, desalting and reducing lipid, adding brown sugar and ferment powder in proportion, sealing, standing and fermenting, regularly stirring, and filtering. The method has the characteristic of resource utilization of the kitchen waste, and the prepared agricultural enzyme and the fermented residue organic fertilizer are used for field soil improvement and crop weight gaining. The method can effectively solve the problem that kitchen waste is difficult to treat, reduce environmental risks, save pesticide and chemical fertilizer input, reduce production cost, increase the yield of agricultural products and improve the quality of the agricultural products. The method has remarkable ecological benefits, economic benefits and social benefits, is beneficial to agricultural sustainable development and has a wide industrial prospect.

Description

technical field [0001] The invention relates to a method for preparing agricultural enzymes, in particular to a method for preparing agricultural enzymes by using kitchen waste, which is applied in the technical fields of agricultural soil improvement, prevention and control of crop diseases and insect pests, and kitchen waste resources. Background technique [0002] Food waste refers to perishable organic waste such as fruits and vegetables, food scraps, leftovers, melon and fruit peels discarded in residents' daily life and activities such as food processing, catering services, and unit meals. Food waste is perishable and degenerates, emits foul smell, breeds mosquitoes, and spreads germs. At present, food waste is often treated by composting, feed and landfill. Composting tends to generate greenhouse gases, and the cost of feed is high; while the leachate produced by landfill and composting is likely to cause secondary pollution to water sources and soil. With the devel...
