景观保护,即使是有机耕作,他建议只要每英亩产量相当于常规养殖的产量那么就是可行的。
Even organic farming, he suggests, is justifiable in the context of landscape preservation only if the per-acre yields equal those of conventional farming.
这样一来,植株就可以排列的更为紧密,每英亩产量也随之翻番,每一层楼内都可以种好几排矮株作物。
So plants could be packed tighter, doubling yield per acre, and multiple layers of dwarf crops could be grown per floor.
