4、有利于土壤有机碳的累积;免耕秸秆还田(NTS)方式0～5cm土层土壤有机碳累积量比传统耕作(CTA)方式高1810%,旋耕秸秆还田(RTS)0～5和5～10cm土层比CTA分别高1716%和2510%,而翻耕秸秆还田(CTS)方式10～30cm土层土壤总有机碳累积量比CTA高3118%;CTA转变为NTS-2-1后,源于农田投入的碳排放减少了5413kg·hm·a,而转变为CTS、RTS后,分别增加了-2-1-2-14619kg·hm·a和3414kg·hm·a;综合土壤碳累积与农田投入碳排放可知,传统耕作转变为保护性耕作方式后可实现由“碳源”向“碳汇”的转变,而CTS、RTS、NTS3种耕
