At present, the soil fertility of the early hours is very low, and many farmers set aside the wheat straw again. It is a pity. Some people advocate the development of animal husbandry straws to the field, in general, is correct. If you can not belly to field, straw directly back to the field, it is desirable.

Since the beginning of 1982, 9.8 mu of early-season wheat sowed in Guangxing, the village of Lintao County, has been harvested from high-yielding crops (3-4 inches) annually.
