Technical Field

The invention relates to the technical field of soil remediation, in particular to a CNT natural agricultural method active soil technology.

Background

Since the industrial agriculture, the long-term use of pesticides and fertilizers leads to the consequences of soil hardening, acidification and the like in farmlands. Some agricultural experts adopt a natural farming method to cultivate, and hopefully utilize the natural farming method (the natural farming method proposed by Ongtian Jieji: an agricultural production mode following the laws of nature, taking soil cultivation for maintaining soil vitality as a basis, and never using any chemical fertilizer, pesticide, various growth regulators and any additives of harmful soil) to make agriculture free from the constraint of chemical fertilizer and pesticide. However, after long-term practice, the cultivation mode can play a certain role in soil remediation, but the yield falls off along a cliff, which is obviously not sustainable by modern agriculture. The main reason is that the general soil is difficult to bear the high fertility requirement of the current crops.
