The farms set goals and ensured rational organization of manpower to cultivate more sunflowers, perilla-oil plants, etc.

They found out idle land, increased the soil fertility and sowed seeds suited to local soil and climatic conditions.

Various methods including inter-tilling have been applied to grow perilla, rape and other oil-bearing plants.

The oil-bearing crops which are of high nutritional and pharmacological effect were planted on the edge and ridges of fields and other idle land, and are being tended responsibly.
