石林烟区植烟土壤养分动态变化及施肥对策
Studies on Soil Nutrients Dynamic Changes of Tobacco-growing Areas and Fertilizing Strategy in Shilin
摘要
Abstract
Our objectives were to study on the tobacco growing soil nutrient dynamic changes of Shilin country through the correlation analysis of 4 towns tobacco growing soil nutrient contents and planting life. Using GPS satellite positioning system to point sampling in Lumeiyi town, Banqiao town, Dake town and Changhu town of Shilin country representative sampling plot point in alternate years sampling, each village or town collected 40 samples. Sample ages were 2000, 2002, 2004, 2006, 2008, 2010 years respectively. Dam area represented by Lumeiyi town and Banqiao town tobacco growing soil nutrient status had deterioration trend following planting age increasing, which need to increase the a-mount of organic fertilizer, suitable application of magnesium, potassium, nitrogen and phosphorus fertilizer in the production process. Mountainous areas represented by Dake town and Changhu town of tobacco growing soil nutrient contents increased following planting age increasing, nutrient content was relatively stable which need reasonable application of magnesium, potassium fertilizer and comply with the principle of increasing nitrogen and reduction phosphorus and combination of soil.关键词
