为了改良土壤的物理性状,并探讨连续施用生物炭对植烟土壤物理性状的长期效应,以云烟87为试材,通过3年定位试验研究了连续施用生物炭对植烟土壤物理性状的影响。结果表明:连续施用生物炭能明显影响土壤的物理性状。连续施用生物炭对2015年烤烟生育各时期内土壤含水率均有促进作用,土壤含水率升高了3.243~ 3.983个百分点,且差异极显著,而在2016, 2017年时,连续施用生物炭后在烤烟生育各时期内土壤含水率与对照比较或高或低,但差异均不显著;连续施用生物炭在2015年移栽后30 d时,土壤容重升高0.083个百分点,土壤孔隙度降低3.113个百分点,但差异均不显著,其他年份各时期为连续施用生物炭后土壤容重降...

In order to improve soil physical properties and study the long-term effects of continuous application of biochar on soil physical properties of planting tobacco. Yunyan 87 was selected as testing material and a three years located experiment was designed to study the effects of continuous application of biochar on soil physical properties of planting tobacco. The results showed that continuous application of biochar could obviously affect the soil physical properties. Continuous application of biochar promoted the soil moisture content in each periods of fluecured tobacco growth in 2015, the ...
