High-temperature composting process of wheat straw

Abstract

The invention discloses a high-temperature composting process of wheat straw. The high-temperature composting process includes the following steps: (1), using a grass grasping machine to stack the wheat straw to form a long pile; (2), laying two micro-spraying hoses on the wheat straw pile, utilizing a full-automatic water supply system for micro spraying through the micro-spraying hoses, and continuously spraying water for 72 hours; (3), dissolving composting agent and urea in a water storage tank of the full-automatic water supply system according to a mass ratio of 1:5, and uniformly spraying a material solution through the micro-spraying hoses; (4), after spraying of the material solution is completed, continuously watering for 6 hours through micro spraying; (5), covering thin films on the wheat straw pile and the micro-spraying hoses laid above the same, sealing for fermentation for 15 days, and regularly measuring and monitoring temperature and humidity. The full-automatic water supply system is utilized to spray water and material to the straw pile through the micro-spraying hoses, so that the objectives of sufficient water soaking and uniform material scattering of the straw pile can be achieved, the straw can be composted quickly, automation level is high, and time and labor are saved.

Description

technical field [0001] The invention relates to the field of recycling of agricultural crops, in particular to a high-temperature composting process of wheat straw. Background technique [0002] At present, the output of wheat straw in my country is huge, and hundreds of millions of tons of wheat straw are produced every year. These huge amounts of wheat straw have brought great pressure to the rural environment in our country. How to deal with these straws has become the primary problem of various local agricultural management departments. Burning will produce air pollution, seriously affecting people's life and transportation, and the random pile of wheat straw will affect the appearance of the countryside, and every straw pile will become a fire hazard. Therefore, how to deal with straw, turn waste into treasure, and ensure the sustainable development of agriculture has become a hot issue that needs to be solved by the whole society. [0003] Straw itself is rich in nitro...
