Technical Field

The invention relates to the technical field of straws, in particular to a method for fully utilizing and recycling straws.

Background

The straw is a general term of stem leaf (ear) part of mature crops. Typically refers to the remainder of the wheat, rice, corn, potatoes, oilseed rape, cotton, sugar cane and other crops (typically roughages) after harvesting the seed. More than half of the products of crop photosynthesis exist in the straws, and the straws are rich in nitrogen, phosphorus, potassium, calcium, magnesium, organic matters and the like, are multipurpose renewable biological resources, and are also coarse feed.

With the improvement of living standard, most household rice cooking adopts coal gas or natural gas, straws produced by crops can be discarded in a large amount or buried in situ and then fermented into fertilizer, the treatment mode is easy to cause waste, pests on the straws are buried under the straws after the straws are buried in situ, and the pests are easy to damage the crops in the next season.

The above two processing methods have new problems: 1. the method for manufacturing the boards comprises the steps of crushing the recycled straws, and then extruding the crushed straws by a matched die of a hydraulic press, wherein the boards produced by the method can be directly discarded after being damaged in the later period, cannot be reused, can also cause new garbage, and cannot be directly combusted, because flame-retardant substances are required to be added in the board manufacturing process, most of the board products manufactured by the method can only be applied to low-grade products such as furniture, tables, chairs, stools and the like, and the utilization value is limited; 2. the method and the cost are higher, and compared with the method and the cost for preparing the charred coal by using thicker trees, the method and the cost are obviously superior to those of straws.
