Infl uence of soil hardness on fl ue-cured tobacco production and causes analysis
摘要
Abstract
Soil compaction is one of the key constraints on soil quality and crop growth in cultivated land. In order to study the infl uence of soil hardness on flue-cured tobacco production and to analyze its causes, soil samples from Henan central south tobacco-planting areas including counties of Biyang, Jiaxian and Xiangxian were collected, and economic traits and characteristics of soil hardness and its correlation with soil physical, chemical and biological indexes were analyzed. Results showed that soil surface hardness and subsurface hardness were 19.78 kg·cm-2and 40.72 kg·cm-2, respectively. Soil surface hardness and subsurface hardness accounted for 86.7% and 69.3% of the samples in the range of 10-30 kg·cm-2and 30-50 kg·cm-2, respectively. Soil surface hardness and tobacco yield and output value among the three counties showed no signifi cant diff erences, whereas soil subsurface hardness in Biyang was lower than that in Jixian. Yield, value and the proportion of superior leaves were signifi cantly aff ected under the condition of soil surface hardness above 30 kg·cm-2. Soil surface hardness was positively correlated with subsurface hardness, clay content and bulk density, and negatively correlated with silt content, total porosity, alkaline hydrolyzable nitrogen content, soil protein index, active carbon content and phosphatase activity.关键词
