收获的要比你需要的多

03_wieviel_wovon_OhneRand_E

很难相信在2000平方米的土地上竟能生长这么多东西!能够收获数以吨计的鳄梨、番茄、卷心菜、胡萝卜、麦子以及土豆。但是谁能吃掉这么多东西呢?答案就在于多样化种植。此外,作物产量根据地区、年份不同,差别很大。

说到蔬菜,生在在温室里的蔬菜和田里的蔬菜是有区别的。例如,例如,比利时和荷兰保持了单位平方米西红柿最高产量的记录,因为这些番茄都种在大棚里,全年都在生长,但是这也是非常耗费能量和化肥。在其他地区,更多番茄是种在田里,只有在合宜的季节,才会有收成。

单位面积的产量的最大化往往与人工化肥和农药的大量使用有关,所以这绝不是环境友好的种植模式。
