Problems solved by technology

[0002] Straw usually refers to the remaining parts of wheat, rice, corn, cotton, sugarcane and other crops after harvesting seeds. So far, crop straw, as a non-renewable resource, has not been effectively developed and utilized, and its own decay rate is extremely slow , affecting the cultivation of crops, so the majority of farmers mainly deal with incineration and returning to the field, which not only causes waste and environmental pollution, but also the pollution index of sulfur dioxide, nitrogen dioxide and dioxins produced during the incineration process reaches a high peak, which is harmful to the environment. The mucous membranes in the eyes, nose and throat of the human body are highly irritating, causing coughing, chest tightness, and tears in mild cases, and bronchitis and cancer in severe cases. This is contrary to the concept of an environment-friendly and resource-saving society advocated by our country. Therefore, Finding a reasonable and effective straw treatment method has become an urgent problem today, but most of the current straw treatment methods can only deal with the above-ground or underground straw, and cannot make the best use of them.

Embodiment 1

[0026] A method for processing rice straw, comprising the steps of:

[0027] 1. In the field, the straw is cut into the root stubble part and the upper stem part in the ground;

[0028] 2. The upper stem is treated to make feed:

[0029] (1) Putting the upper stem part of the fresh rice straw into the extrusion equipment, pouring the extruded juice into the paddy field, and drying the extruded straw;

[0030] (2) The straw is crushed into 3 cm straw particles, after being treated by alkalization and salt water immersion, the straw particles are dehydrated by a centrifugal dehydrator, and feed particles are made by a granulator;

[0031] Wherein, the specific step of alkalization treatment is to soak the pulverized straw particles in an aqueous alkali solution for 8 hours at a temperature of 20°C, the mass percentage concentration of the aqueous alkali solution is 3%, and the alkali in the aqueous alkali solution is hydrogen hydroxide sodium.

Abstract

The invention discloses a treatment method of rice and wheat straw and relates to the technical field of treatment of crops. The treatment method of the rice and wheat straw comprises the following steps: 1, cutting the straw into underground root stubble parts and upper-end stem parts in a field; 2, treating the upper-end stem parts to prepare feed; 3, returning root stubbles back to the field. According to the invention, the different aboveground and underground straw parts are treated and time is saved; the straw of all the parts are reasonably subjected to environment-friendly treatment in all aspects, so that the value of the straw is realized.
