Analysis of Soil Nutrient, pH and Fruit Mineral Nutrition in Mango Orchard in Lingshui
摘要
Abstract
The basic status and correlation of soil nutrients and mineral elements in the mango orchard of Lingshui were sutudied and the paper would provide a theoretical reference for the scientific and rational development of fertilization strategies in the main mango producing areas of Lingshui.The soil samples and fruit samples collected from the 0-20 cm and 20-40 cm soil layers of the mango orchards in the main mango producing areas of Lingshui were analyzed by nutrient analysis.Through the method of multiple stepwise regression and linear programming,the nutrient optimization scheme of the orchard was pH 6.01-6.85,organic matter 20-25.22 g/kg,alkaline nitrogen ≥ 90 mg/kg,available phosphorus 22.15-40 mg/kg,available potassium ≥ 100 mg/kg,exchange calcium ≥ 1 800 mg/kg,exchange magnesium 100-144.15 mg/kg,available sulfur ≥ 16 mg/kg,available iron ≥ 4.5-20 mg/kg,available manganese ≥ 30 mg/kg,available copper 0.2-1.03 mg/kg,available boron 0.5-2 mg/kg.The soil organic matter,nitrogen,boron effective level of active sulfur,active calcium,magnesium effective are generally low,and most pH are not suitable for mango planting.More organic fertilizer with nitrogen,boron,sulfur,calcium,magnesium added are recommended.The fertilizer should be mainly applied as basal.The fertilization should be based on the fertility balance of different orchards,and trace elements should be applied in critical physiological periods.关键词
