Abstract

Abstract: In order to explore the effects of biochar as soil conditioner on the nutrients of tobacco planting soil, Yunyan 87, a main cultivated variety in Hu'nan Province was used as experimental material to study the effects of different biochar application amounts (CK: 0 kg/hm2；T1:3 000 kg/hm2; T2: 3 750 kg/hm2; T3：4 500 kg/hm2） on soil nutrients in a field experiment. The results showed that biochar application could significantly improve the contents of soil organic matter, alkaline hydrolysis nitrogen, ammonium nitrogen and available potassium, and all of them showed an tendency of first increase and then decrease along with the increase of biochar application amount. From the view point of improving soil fertility, the best biochar application amount was the level of 3 750 kg/hm2.

Key words: biochar, planting tobacco soil, nutrients

摘要： 为探讨生物炭作为土壤改良剂对植烟土壤养分含量的影响，以湖南烟区主要栽培品种云烟87为试验材料，通过大田试验研究了不同的生物炭用量（CK：0 kg/hm2;T1：3 000 kg/hm2；T2：3 750 kg/hm2；T3：4 500 kg/hm2）下植烟土壤中的养分含量。结果表明：施用生物炭能够显著提高植烟土壤有机质、碱解氮、铵态氮及速效钾含量，且随着生物炭施用量的增加呈先升高后降低的趋势，从改良土壤肥力效果来看，生物炭施用量在3 750 kg/hm2的水平下较为适宜。
