江西不同类型紫色土烤烟氮、磷、钾含量的规律研究
N,P and K distribution in flue-cured tobacco grown in different types of purple soils in Jiangxi province
摘要
Abstract
Soil and tobacco samples were collected by point to point in purple soil and were tested in 2009 to investigate nutrient distribution in flue-cured tobacco planted in different types of purple soil in Jiangxi province. Results showed that soil available N, P, K and total N, P, K were 52. 8mg/kg, 14.4mg/kg, 152. 2mg/kg, 0. 78g/kg, 0. 75g/kg, and 17. 7g/kg, respectively in purple soil. Purple soil, in general, was characterized with low nitrogen, low phosphorus and high potassium, correspondingly tobacco phosphorus content was low and potassium content was high, suggesting that application of phosphate fertilizer should be moderate in purple soil. Among the studied tobacco in different purple soils, there was no significant difference in tobacco nitrogen content and phosphate content, but absorption of nutrients of potassium was better in alkaline purple soil. Nutrients distribution in tobacco leaf were that content of phosphate rose with position of leaves from lower to upper in acid and neutral purple soils, and content of nitrogen and phosphate showed no significant difference with position of leaves.关键词
