中文摘要:
      调查了湛江辣椒主要种植区土壤养分状况,结果显示,辣椒种植区土壤pH 平均为5.09,酸性 土壤占63.4%,强酸性土壤占14.6%;土壤有机质平均为2.10%,其中低于2.00% 的土壤占56.1%,总体处 于中等偏下水平;土壤碱解氮含量平均为127.1 mg/kg,90.0 mg/kg 以上土壤占87.7%,处于中等水平,而 有效磷、速效钾平均值分别为72.5、231.0 mg/kg,均处于丰富水平;中微量元素方面有效钙平均值为594.8 mg/kg、有效镁平均值为145.7 mg/kg,均处于中等偏下水平,有效锌含量丰富,而有效硼平均值为0.24 mg/kg, 低于0.64 mg/kg 的土壤占100.0%,处于缺乏状态。建议在该区域可适当注重氮素投入,注意氮磷钾平衡施 肥,增施有机肥和秸秆回田培肥土壤,适当补充钙镁元素,采用叶面施肥补充硼元素。以土壤肥力检测为依 据开展科学配方施肥有利于提高辣椒种植效益。
英文摘要:
      The soil nutrient status in Zhanjiang pepper planting areas were investigated in this research. Results showed that the average of soil pH value was 5.09,63.4% was 4.5-5.5 and 14.6% was below 4.5. The average value of soil organic matter was 2.10%,56.1% was below 2%,the soil organic matter was at medium to low level. Available nitrogen content was at a moderate level with average value of 127.1 mg/kg,87.7% was higher than 90.0 mg/kg,while available phosphorus( average value of 72.5 mg/kg) and available potassium(average value of 231.0 mg/kg) were abundant. Available calcium content( average value of 594.8 mg/kg) and magnesium content(average value of 145.7 mg/kg) were at medium to low level,and available zinc content was rich,while available boron content(average value of 0.24 mg/kg) was deficiency,all samples were below 0.64 mg/kg. It is suggested that in this region,nitrogen fertilization should be paied attention and especially the balance fertilization of nitrogen,phosphorus and potassium, application of organic manure and straws should be increased to improve soil fertility,calcium and magnesium fertilizer input should be added. In addition,the boron element could be supplemented by foliar application. Scientific fertilization based on soil test would be good to improve the benefits of pepper planting.
