无土栽培是指不用天然土壤,而用基质进行栽培作物的方法。现在许多学校都开展了这一实验活动,它丰富了学生的课外活动,提高了学生的动手能力,也使学生更加热爱科学,热爱大自然。但是,无土栽培是一项技术性很强的一门技术,由于一些条件的制约、它能够在学校长期深入开展,有比较大的困难,本人利用学校生物园开展这一活动多年、总结了一些成功和失败的经验。总结如下供大家参考。
Soilless cultivation refers to a method of growing a crop using a substrate without using natural soil. Many schools now carry out this experimental activity. It enriches students’ extra-curricular activities, improves their hands-on ability, and enables students to love science and love nature. However, soilless cultivation is a highly technical one technology. Due to the constraints of some conditions, it can be carried out in schools for a long time and has relatively large difficulties. I have used this school’s biological park to carry out this activity for many years and summarized some of them. Success and failure experience. The summary is as follows for your reference.
