- 摘要:
- 于2009年对肇源县主要乡镇农区土壤进行采集,并通过引用养分丰缺指标,根据主栽作物的氮、磷、钾、微量元素需要规律,对土壤肥力情况进行测定。结果表明:肇源县土壤容重在1.2~1.3 g·cm-3,土壤结构较好,pH呈中性,碱解氮和速效钾含量处于较高水平,速效磷含量处于中等水平,有效锌和硼含量处于缺乏水平。因此,应重点推广配方肥料,增施有机肥料,且有机肥和无机肥配合施用。
- Abstract:
- The soils from main township of Zhaoyuan county were collected in 2009,the soil fertility situation was determined by introducing fertility index according to the nitrogen,phosphorus,potassium and trace elements need law of main crop.The result showed that the soil bulk density was 1.2~1.3 g·cm-3,soil structure was better,pH was neutral,alkaline nitrogen and available potassium content were at a high level,available phosphorus content in the secondary level,effective levels of zinc and boron content were at insufficiency level.Therefore,it should focus on promoting formula fertilizers,applying organic fertilizer and with inorganic fertilizer together.
