Method for refining microbial organic fertilizer with branch lops

Technical field

The present invention relates to a kind of is the method for the suitability for industrialized production bio-organic fertilizer of main raw material with the branch pruning thing, and it belongs to urban afforestation waste environmental protection treatment, green fertilizer technical field.

Background technology

The branch pruning thing is a municipal solid wastes, has increased the pressure of urban waste amount and city environmental protection, and general in the past the employing burned and the landfill disposal method.Its result treatment expense height causes new environmental pollution, has increased emission of carbon-dioxide.Therefore progressively forbid incinerating method.

In recent years, along with the progressively raising of environmental consciousness, recognized branch pruning thing recycle value, Shanghai municipalization unit just adopts pulverizer that the branch pruning thing is pulverized directly covering method of back.But directly covering can cause serial negative effect: 1). when blowing, coverture causes air-borne dust to pollute; 2). because the coverture carbon-nitrogen ratio of not becoming thoroughly decomposed by fermentation is very high, can consume a large amount of nitrogenous fertilizer and oxygen in the soil, unfavorable to the arboreal growth that covers; 3). coverture is that mould grows, the disease insect breed and growth provides suitable place; 4). influence Soil structure.

Pulverize the direct negative effect that causes that covers in back in order to reduce the branch pruning thing, there is unit to take up to adopt compost now and makes substraturn approach, the key of this method and technology is a fermentation maturity, existing compost fermentation technical matters is simple, the branch pruning thing is difficult to be ground into the optimum size that meets the fermentation requirement, and the carbon-nitrogen ratio height have a strong impact on the fermented quality and the effect of branch pruning thing, and the matrix of making can only be as soil improvement agent.Even after secondly fermentation maturity finishes, made compost, because of wherein the major fertilizer elements N-P-K content is very low, fertilizer efficiency is poor, supply with vast rural area only and use as land for growing field crops base manure, and amount of application is big, does not have commodity value.

Summary of the invention

The present invention overcomes the problems and shortcomings that exist in the above-mentioned prior art field, proposing the object of the invention one is: for the disposal of city branch pruning thing provides a reliable feasible effective way, realize the degree of depth utilization of branch pruning thing, turn waste into wealth, walk out a new approach of developing the economy and protecting environment to combine; Purpose two is: a kind of biological organic fertilizer that improves soil quality and meet national Ministry of Agriculture standard (NY525-2002) is provided, is widely used in green food farm crop such as vegetables, fruit tree, lawn, flowers, herbage, greening tree etc.In order to reach above-mentioned two projects, the present invention adopted three grades by different level disintegrating process, fermentation maturity processing condition, add substance methods such as humic acids.Concrete grammar is as follows:

Three grades of layering disintegrating process: branch is through blade chopping for the first time, make fragment or short section after, carry out second time and pulverize, stack retting is pulverized after 30 days more for the third time, adopts sieve plate control fineness, reaches the optimum fineness (0.8-1.2mm particle diameter) of fermentation requirement.Fermentation maturity technology: introduce degraded cellulose class bacterial classification, control water content 56%, the adjustment carbon-nitrogen ratio is 26-28, the complete index of becoming thoroughly decomposed is weighed less than 20 with carbon-nitrogen ratio.Add dried cow dung and humic acid after the fermentation, add behind the humic acid and derive multiple new derived materials such as containing xanthohumic acid, ammonium humate, potassium humate, thereby increase N-P-K content in the product, reach N-P-K content greater than 4% standard-required.In addition, also add and contain multiple bacillus category functional microorganisms such as vinelandii, root nodule bacterium, phosphorus bacteria, silicate bacteria, after reaching product and being manured into soil, decompose unabsorbable phosphorus and potassium and nitrogen pick-up effect in the soil.

Embodiment
