Embodiment 1

[0040] In this embodiment, a method for composting and decomposing agricultural waste in a closed greenhouse is provided, the method includes using a closed greenhouse to compost and decompose the agricultural waste under conditions of controlled temperature and humidity, wherein the The enclosed greenhouse is equipped with spraying equipment, and the top of the greenhouse is equipped with an exhaust port; the agricultural waste includes agricultural straw, and is packaged by crushing briquettes before composting and decomposing.

Embodiment 2

[0042] On the basis of Embodiment 1, this embodiment further includes that the interior of the enclosed greenhouse is divided into multiple layers from top to bottom, each layer is provided with a temperature detector and a humidity detector; and the temperature detector and humidity The detectors are set in the electronic monitoring system.

Embodiment 3

[0044] On the basis of Embodiment 2, this embodiment further includes that the inside of the closed greenhouse is also provided with turning equipment for turning the piled organic waste; and the bottom of the closed greenhouse is also provided with The air inlet is used to let in natural wind. The turning equipment is FDZ-2600 self-propelled turning machine. In addition, the exhaust port is also connected with an outer pipe, and the outer pipe is equipped with heat preservation equipment for supplying heat to the outside of the greenhouse; and a recovery container is installed underground to recover the waste liquid generated after heating for use The basic fermentation broth in biogas digesters.

Abstract

The embodiment of the invention discloses a closed greenhouse stacking and decomposing method for agricultural wastes. According to the method, agricultural wastes are stacked and decomposed in a closed greenhouse under controlled conditions of temperature and humidity, the closed greenhouse is internally provided with spraying equipment, and vent holes are formed in the top of the greenhouse, andthe agricultural wastes comprise agricultural straw which is crushed, caked and packaged before stacking and decomposition. By adopting the method, the problems that a conventional stacking and decomposing method has seasonal and regional limitations, and decomposition and decay of straw and agricultural wastes cannot be completed in a short time can be solved.

Description

technical field [0001] The invention relates to the technical field of agricultural fertilizer production, in particular to a method for stacking and decomposing agricultural waste in a closed greenhouse. Background technique [0002] Agricultural waste includes waste discharged from agricultural production, agricultural product processing, livestock and poultry breeding and rural residents' life. Among them, agricultural straw is a large and important agricultural waste. With the development of society and the widespread use of new energy sources such as coal, electricity, natural gas, and liquefied petroleum gas in rural areas, the pace of urbanization in rural areas has accelerated, making a large amount of straw that was originally used for heating and cooking idle, and it has become an important area for farmers to use in agriculture. A significant burden in production. People usually process the stalks by burning, so that a large amount of stalks are burned in the sp...
