Problems solved by technology

[0002] Existing leafy vegetable stalks in large-scale cultivation bases or in farmers’ markets will have a large number of rotten vegetables that can no longer be eaten and will be discarded, and some leafy vegetable stalks that cannot be used as feed are directly stacked and discarded. It is treated as waste, which not only wastes resources but also causes environmental air pollution when stacked for a long time. However, the common utilization method for straw in the prior art is to store the straw directly, so that the fertilizer prepared by the long-term reaction of the straw , its cycle is long, the reaction efficiency is low, and there is no good nutrient

Embodiment 1

[0022] Embodiment 1: An application technology and method for returning leafy vegetable stalks to the field for reuse, the application technology includes the following processes:

[0023] (1) First select the stalks of leafy vegetables, and manually select the stalks that are not suitable for direct use as feed or rotten straws, and then rinse with water to clean the dust on the surface of the stalks or the attached insects and dry;

[0024] (2) Process the dried stalks by crushing or using a hay cutter to chop the stalks, keep the length of the stalks broken at 1 cm, and lay the crushed straws with vegetable leaves layer by layer in the fermentation tank In the process of laying, the urea aqueous solution is evenly sprayed on the surface of the vegetable leaves and straw, and the straw decomposing agent and the insecticidal and bactericidal smoke agent with bottom poison are added to it, and then the fermentation tank is sealed;

[0025] (3) After 24 hours of sealing treatm...

Abstract

The invention discloses an application technology and method for returning straws of leafy vegetables to fields for reutilization, and belongs to the technical field of returning application, and theapplication technology comprises the following steps: (1) firstly selecting the straws of the leafy vegetables, (2) processing the aired straws, chopping the straws in a crushing mode or by a hay cutter, keeping the crushed length of the straws at 1-3 cm, then placing the straws in a fermentation tank for decomposition and fermentation, (3) mixing a well decomposed organic compound fertilizer anda microbial agent into biogas slurry, fully stirring and mixing, then continuously fermenting at 65-80 DEG C for 15-30 days, and preparing into an biological organic fertilizer, and (4) returning thestraws of the leaf vegetables to the field for use; the straws of the leaf vegetables are returned to the field to be utilized, the the straws of the leaf vegetables are reasonably utilized, the produced fertilizer can increase nutrients for the land, meanwhile, the cost is saved, and environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of field returning application, in particular to an application technology and method for returning leaf vegetable straw to field for reuse. Background technique [0002] Existing leafy vegetable stalks in large-scale cultivation bases or in farmers’ markets will have a large number of rotten vegetables that can no longer be eaten and will be discarded, and some leafy vegetable stalks that cannot be used as feed are directly stacked and discarded. It is treated as waste, which not only wastes resources but also causes environmental air pollution when stacked for a long time. However, the common utilization method for straw in the prior art is to store the straw directly, so that the fertilizer prepared by the long-term reaction of the straw , which has a long cycle, low reaction efficiency, and no good nutrients. Therefore, we propose an application technology and method for returning leafy vegetable straw ...
