The area under crop cultivation is less than the area under cultivation of arable land, i.e.: (5) where is the maximum acreage of cropland j. 3) Based on 23 years of crop cultivation, it is assumed that the number of acres of flat dry land is not less than 35 acres, the number of acres of terraced land is not less than 20 acres, and the number of acres of hillside section is not less than 13 acres, that is: ≤ 35, = 1,2, ⋯ ,6≤ 20, = 7,8, ⋯ ,20≤ 13, = 21,23, ⋯ ,26 (6) 4) For ease of management, crop cultivation should not be spread too thinly, but the advantages offered by joint cropping should be taken into account, and a constraint is therefore imposed on a maximum of three crops on a piece of arable land, namely: (7) 5)	cache/ajst-27756.pdf	txt/ajst-27756.txt
