为了降低低温冻害发生时土壤温度对小麦植株的危害，通过2010、2011年生物炭在麦田应用，研究了生物炭对黄淮麦区土壤温度的影响。结果表明，施炭与不施炭相比，施炭可以提高冻害天气下最低温度，降低最高土壤温度，增加土壤积温，对小麦提高抗霜性具有一定积极的作用。

In order to reduce the harm of soil temperature on wheat plants when freezing occurs, in 2011 and 2010, the effect of biochar on the soil temperature was studied by using the biochar in wheat field. The results showed that, compared with no applied biochar and applied biochar, applied biochar could improve the minimum temperature of freezing weather, reduce the maximum soil temperature and increase soil accumulated temperature, and had positive effect on the wheat frost resistance.
