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. It features high coarse fibre content (30-40%), and lignin content. Although the lignocellulose cannot be utilized by pigs and chickens, the lignocellulose can be absorbed and utilized by livestock such as ruminants, cattle and sheep, at present, farmers generally burn straws, and the straws can cause serious pollution after burning, thereby causing destructive damage to air. Therefore, in recent years, the burning of the straw is generally strictly controlled. However, the prohibition of burning is a solution, and another method is to complete the resource conversion of the straw, namely how to convert the straw into another usable resource. Through research, the straws can be used as feed for some large animals, and the most critical step for preparing the feed is to crush the straws.
