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.

The straw returning field is a soil fertility increasing and yield increasing measure which is generally regarded as important in the world at present, and has the functions of increasing fertilizer and increasing yield while avoiding atmospheric pollution caused by straw burning. The straw returning can increase soil organic matters, improve soil structure, loosen soil, increase porosity, reduce capacity and promote microbial activity and crop root development. The effect of straw returning to field, increasing fertilizer and increasing yield is obvious, the yield can be increased by 5% -10% generally, but if the method is improper, the adverse phenomena of soil germ increase, crop disease increase, seedling shortage (runt seedling) and the like can also be caused. Therefore, a reasonable straw returning measure is adopted, and a good returning effect can be achieved.
