There are 8 rows of wheat with 12 cm of row spacing； 3 rows of maize with 40 cm row spacing and 25 cm plant spacing； S2, after the wheat is harvested in the year, replant 6 rows of common vetch in the wheat belt, in order to achieve wheat-maize inter-cropping with green manure； in S3, in the frost season of the year, covering the green manure on the field in order to realize perennial mulching, water retention and wind erosion prevention； in S4,in the next year,the two crops' strips will be cultivated in exchange with rotary tillage for planting wheat and maize , which is designed to achieve inter-belt rotation, avoiding potential weakness or problems that may occur in continuous cultivation. Also, inter-belt rotation can help balance soil nutrients required by the two different crops in the alternate strips. In this invention, the resource is efficiently utilized and the productivity of farmland is improved, so that the sustainable planting mode can change the traditional production mode and create a new type of sustainable agricultural production mode.
