Problems solved by technology

However, there are also disadvantages. For example, the composition of farmyard manure is complex, contains a lot of pathogenic microorganisms, requires a series of treatment processes such as composting, and the fertilizer effect is slow. It needs to be applied to the soil half a month or more in advance to play a good role.
The fertilizer efficiency of biological bacterial fertilizer is closely related to the number of viable bacteria, temperature, moisture, pH, etc., so the requirements for environmental conditions are strict, and the cost is expensive, and it is not easy to promote

Embodiment 1

[0028] In this example, rapeseed cake was used as a raw material to prepare the calcium polypeptide accelerator of the present invention that can increase the number of soil micro-ecological populations.

[0029] at 10m 3 Add 2,800kg of crushed rapeseed cake to the batching bucket of , and dissolve 560kg of quicklime with 5,600kg of water to prepare a lime milk solution. Put this lime solution into the batching bucket with rapeseed cake, stir evenly, and pump it into 10m 3 Into the reaction kettle, put 0.6~0.9Mpa steam into it and heat it to 125°C, keep it warm for 2 hours, take a sample from the beaker and observe, the color of the solution is dark brown and the solid and liquid parts have been separated, which means that the reaction is complete, cool to room temperature, and use pH test paper The measured pH value is 10.5, and this solid-liquid mixture is the calcium polypeptide promoter.

Embodiment 2

[0031] In this example, the calcium polypeptide promoter capable of increasing the number of soil micro-ecological populations of the present invention was prepared by using sludge from a food factory as a raw material.

[0032] at 5m 3 Add 3000kg of food factory sludge (80% water content, 48% protein in dry product) into the batching tank of the food factory, dissolve 180kg of quicklime with 360kg of water to prepare a lime milk solution, and input this lime solution into the batching tank with sludge , stir evenly, and use a pump to input 5m 3 Put 0.6~0.9Mpa steam into the reaction kettle and heat it to 155°C, keep it warm for 4 hours, open the exhaust valve, if there is an odor of sludge, it means that you can’t take samples for observation, you need to keep warm for 1 hour, and use a measuring cylinder when there is no smell Sampling, if the solution is turbid, it means that the slightly soluble lime has not been converted into calcium polypeptide, if it precipitates quic...

Abstract

The invention discloses a preparation method and application of a calcium polypeptide promoter for improving soil micro-ecological population quantity and belongs to the technical field of protein waste treatment and recycling. The preparation method comprises the following steps: adding a protein-containing raw material into a high-temperature reaction kettle; after properly adding calcium oxide or quicklime and water into the reaction kettle, heating up to 121-170 DEG C, keeping the temperature for 0.5-6.5 h, and cooling down to the ordinary temperature to obtain the calcium polypeptide promoter, wherein the protein-containing raw material is food factory sludge, urban life sludge or plant cake meal, and the weight of the added calcium oxide or quicklime accounts for 10-35 percent of that of dehydrated dry sludge or the plant cake meal. The calcium polypeptide promoter can be used for increasing the soil micro-ecological population quantity and quickly promotes microbial growth, and plants planted with the calcium polypeptide promoter is higher in content of chlorophyll than plants planted with ordinary fertilizers, is large in biomass, and contains most soluble starch and other nutritional ingredients in all plants planted with fertilizers.

Description

technical field [0001] The invention belongs to the technical field of protein waste treatment and resource utilization, and specifically relates to the preparation of quick-acting, nitrogen-free organic fertilizers using protein waste and its regulation of soil micro-ecology. More specifically, the invention relates to a method for improving soil A preparation method and application of a calcium polypeptide accelerator for microecological populations. Background technique [0002] With the development of modern agriculture, the country's demand for fertilizers is also increasing. How to obtain high-quality fertilizer is an urgent problem to be solved in my country's agriculture. The fertilizers sold on the market can be divided into three categories according to the different properties and characteristics of the fertilizers. One is chemical fertilizers, also known as inorganic fertilizers, which are fertilizers produced by chemical or physical methods, such as ammonium su...
