生物质炭输入对葡萄果园土壤肥力和产量的影响

Effect of Applying Biochar on the Quality of Orchards Soil and Grape Cropping in Xinjiang,China

【目的】了解果园肥力状况,设置不同有机物输入对土壤肥力的影响,为保持葡萄果园肥力提供理论依据。【方法】采用调查与大田试验相结合,设置不同的有机物料和用量水平,室外和室内测定土壤和植株相关指标。【结果】果园土壤中有机质含量与有机肥投入直接相关,其中可溶性有机碳含量与土壤中有机质含量呈正相关关系;生物质炭相比较农家肥羊粪对于增加土壤中有机质含量作用突出,在提高果树单产方面优势明显,但施入农家肥羊粪有利于提高土壤可溶性有机碳、微生物碳含量。【结论】果园土壤添加生物质炭可以提高土壤中有机质含量并提高作物产量,可以作为保持果园肥力的重要手段之一。

【Objective】To provide theoretical basis for retaining grape orchard soil fertility through investigating orchards fertility conditions and study the effect of biochar on orchards fertility. 【Method】The research technique of investigation and field experiment was adopted to determine correlation index of soil and plant. 【Result】The finding showed that the content of organic was related to organic fertilizer,and the solubility organic carbon was positively correlated to the content of soil organic; compared with farmyard manure,biochar could increase the organic matter of soil and increase the cropping of grape. Farmyard manure could increase the soil soluble organic and microbe carbon. 【Conclusion】Adding biochar in orchard soil could increase the content of organic matter and crop output,and it could be one of methods to retain orchard fertility.
