摘要
通过定点试验,研究不同耕作方式对宜宾烟区耕层土壤物理性状的影响。结果表明:翻耕能显著提高0~20 cm耕层土壤含水量,有助于降低耕层土壤容重大小,有效降低土壤紧实度,从而改善耕层土壤结构,有利于农作物的生长发育。
The effects of different tillage methods on physical properties of the plough layer soil in Yibin tobacco area were studied by fixed-point experiment.The results showed that plowing could significantly increased the soil moisture content of 0-20 cm layer reduce the soil bulk density and effectively reduce the soil compactness,thus the soil structure of the plough layer soil was improved and it was beneficial to the growth and development of crops.
