...要輪作 – 不同的作物所需的營養不同，其根系所伸展到的深度不同，輪作可以避免土壤中的養分分布不均。例如，葉菜類的作物的根較淺，只能吸收表層土壤中的營養，如果總是種葉菜，土壤下部的養分就發揮不了作用，如果和茄瓜或番茄輪作，就可以避免這種情況發生。另外，輪作還可以打破病蟲害的繁衍周期。 2. 要定期種植綠肥 – 選用豆科植物作綠肥，一來可以給土壤增加可吸收的氮，二來可以增加土壤的有機質含量。每年起碼種一造，多種更好。 3. 多施堆肥作基肥 – 動物糞便加植物廢料經堆漚而成的堆肥，集合著農耕文明的千年智慧。它有化肥所不能取代的功能，它的營養成分全面，在滋養作物的同時，還給土壤有益微生物的生長提供所需...
