Problems solved by technology

However, the traditional fermentation method has weak selectivity to reaction products, and the content of active small molecules such as monosaccharides and amino acids in the obtained fertilizer is low. use of
[0006] Furthermore, the traditional fermentation method has no selectivity for the obtained products, and cannot maximize the utilization of the components and characteristics of different wastes, and the reuse effect is not good
[0007] Therefore, in view of the current technical situation, there is an urgent need for technologies with better adaptability and promotion value, to break through the current barrier of only one or a few kinds of wastes being used in one way, and to improve the backward utilization technology and utilization rate of agricultural wastes. Low current situation, this not only has good practical significance and environmental protection value, is the research hotspot and the key subject in the present field, but also the driving force and foundation that the present invention can be completed

Description

technical field [0001] The invention relates to a method for comprehensive utilization of agricultural waste, and more particularly relates to a method for combining microwave and alkali to prepare fertilizer, which belongs to the technical field of resource recycling of agricultural waste. Background technique [0002] At present, in the vast rural areas of our country, there are many problems in the utilization of agricultural waste resources, such as: lack of corresponding technology and equipment; the processing technology of agricultural waste is simple and backward; the processing capacity and utilization scale are very limited and so on. Among them, the most important problem is that the existing agricultural waste utilization methods will cause environmental pollution. Most resources can only be discarded or incinerated, and the utilization rate is very low. For example, crop straw is mostly used as fuel for one-time utilization. Not only the energy utilization rate ...
