园艺专家漆智平同您讲述“如何培肥庭院土壤”。针对家居庭院的土壤问题,比如说土壤沙化、粘化、酸化等问题,提出改良方法和建议。


漆老师先讲述了肥沃土壤的几个特征 :耕层深厚,土层构造良好;有机质和养分含量丰富;具有适宜的酸碱度。土壤酸碱度为微酸至微碱 (pH6.5~7.5)是多数植物、土壤微生物适宜的生长环境,其有利于作物生长和养分转化。

由于建房时的遗留问题,悉尼的庭院土壤存在以下主要问题:

1、粉砂化:由于悉尼庭院里用的营养土是由有机和砂粒组成,它们经分解、风化后就形成粉砂粒。

2、粘化:有的庭院内没有用营养土,是建房时遗留下的粘土。

3、养分不平衡 :由于长期连续种植一种植物,以及土壤母质本身的问题,造成土壤养分不平衡。

那如何解决土壤中的这些历史遗留问题?点击音频收听园艺专家漆智平为您讲述“如何培肥庭院土壤”。
