specific Embodiment

[0019] The size of the straw reaction chamber of a straw decomposition device is 1m×3m. The materials around the straw reaction chamber and above and below are required to be resistant to temperatures above 60°C without deformation, which is conducive to heat and humidity exchange. The inner wall is fixed with glass and metal clips, and the glass strips on both sides are used to form a grid. The outer casing of the reaction chamber has a wooden frame with glass inlaid, and a glass door is arranged on the front side, and the four sides of the door in contact with the reaction chamber are pasted with rubber strips. The Yadu brand YC-DS180 humidifier is installed on the outer side of the shell of the straw reaction chamber, and the humidification is transported to the straw reaction chamber through the hose. A "horn-type electric heater" model N3-V-2 heater of Beijing Kelleric Heating Equipment Co., Ltd. is placed in the shell on the other side. Thirty 40W light tubes are placed...

Abstract

An experimental facility of straw consists of straw reaction chamber, heater humidifier, exhaust fan, temperature and humidity control unit. Its experiment method includes placing straw in reaction chamber; setting different temperature, different humidity and different illumination condition; observing variation state of straw periodically to obtain proper temperature, proper humidity and proper illumination condition for decomposing straw so as to raise rate of returning straw back to field.

Description

technical field [0001] The invention relates to a straw decomposition experiment research device and an experiment method. Background technique [0002] Crop stalks are often burned by farmers due to the lack of good utilization methods. Burning straw causes air pollution, soil desiccation, microbial reduction, and waste of resources. With the development of ecological agriculture, pollution-free agriculture and organic agriculture, human beings pay more attention to straw returning. Straw is an organic matter. If the straw can be well decomposed and returned to the field, it will directly increase the organic fertilizer content of the soil and reduce the amount of chemical fertilizer applied. This is an effective way for the development of ecological agriculture, pollution-free agriculture and organic agriculture, and it also solves the problem caused by straw burning. Many questions. But there is no dedicated research device and experimental method for straw decomposit...
