酸化生物炭改良苏打盐碱土的效应
Experimental Effects of Acidified Biochar on Saline-sodic
摘要
Abstract
Biochar praised as "black gold" is a promising soil ameliorant. A field experiment was conducted to investigate the soil bulk density, soil water, pH, EC, soil organic matter and so on, in order to clarify the amendment, the applicable value and potential of biochar on saline-sodic soil. Results indicated that the influences of biochar on ameliorating saline-sodic soil were clear. Comparing to biochar without additional treatment, soil bulk density decreased by 0.3%-3.7%, pH decreased 0.2-0.7 units, average soil water enhanced 0.8%, maize productivity increased by 5.1%-7.2%, soil organic matter increased 1.1%-2.5%, enhanced the total and mineral nitrogen after applying acidified biochar. And 2%(20 g·kg-1)acidified biochar showed the best ameliorating effects on saline-sodic soil.关键词
