| 摘 要： | 采用土壤养分状况系统研究法分析了湖北省花生主产区的土壤主要养分含量,并在田间试验下进行了验证.结果表明,湖北省花生主产区土壤普遍缺氯,部分地区缺磷,大面积缺钾和硼.平衡施肥能够明显提高花生产量,但不同地区花生对各元素的敏感程度有所不同,应该在测土基础上合理施肥.

| Abstract: | The main soil nutrient element status in peanut production area of Hubei province was determined by soil nutrient status systematic approach (ASI) and verified in field experiment.The results indicated that nitrogen was generally deficient in experiment site,phosphorus was deficient in partial area.and potassium and boron were deficient in large scale.Balanced fertilization could improve peanut yield significantly,but the sensitivity of peanut to fertilizer was discrepant in different production area.Soil test should be base of the rational fertilization in peanut preduction. |
