Analysis of Soil Nutrients Variation and Soil Characteristics in Different Rotation Systems in Luoyang Tobacco Area
摘要
Abstract
Soil nutrients of 525 soil samples collected from 3 main tobacco-planting regions in Luoyang in 2011 were analyzed,and the results were compared with the analysis results of samples collected in 2002. The results showed that the average content of soil organic matter was 13. 2 g/kg,and 78. 1% of soil organic matter content was in the suitable range;The tobacco fields with higher available nitrogen content (>65 mg/kg) accounted for 16. 6%;The average content of available phosphorus was 9. 52 mg/kg,and 68. 8% of soil available phosphorus was poor;The average content of available potassium was 183. 1 mg/kg; Soil available copper and available iron content was rich in the whole city,and water soluble chloride ion was suitable at large,however, soil available boron and zinc were short; Application of zinc fertilizer was effective for 68% tobacco fields in Luoyang; Besides, manganese deficiency was mainly distributed in Luoning tobacco area. Compared with the results of 2002,the contents of organic matter and available nitrogen was inc sed,however,the contents of available phosphorus and available potassium was decreased; For the microelements,the available zinc slightly decreased,but available boron and water soluble chloride ion significantly decreased. The results of soil characteristics in different rotation systems showed that available nitrogen content of tobacco area was higher in maize and peanut stubble, available phosphorus content of tobacco area in sweet potato and soybean stubble was significantly lower than other crop stubbles,available potassium was lowest in peanut stubble,and the content of microelements in different crop stubbles also had some differences.关键词
