摘要
对植物施加电场后,从土壤的有机质含量、速效性养分含量、团粒结构、密度及持水量、酶活性等方面的变化对土壤进行了深入的研究。找出了土壤在电场作用下使植物质量和产量增加的原因,从而为减轻植物体内的化肥残毒及改良土壤,缓解我国目前化肥供需矛盾的紧张状况,降低林业和农业的成本提供了重要的理论依据。
The changes in organic matter content, effective nutrient content, granular structure, density, water - holding capacity and the activity of enzymes were studied after the plants were treated with electric field. The reasons for the increase of plant quality and yield contributed to the soil were found out under the treatment of electric field. An important theoretical basis was provided for lightening the remnant toxin of fertilizer, meliorating the soil, mitigating the contradiction of supply and need, and for reducing the cost of forestry and agriculture.
