摘要
调查了库尔勒市龙山红枣经济林土壤状况,结合现状提出切实可行的提质增效检疫。在库尔勒市龙山某红枣经济林研究区随机选择3块样地进行土壤状况调查,根据调查结果分析红枣经济林土壤物理性质和土壤养分情况。结果表明:①土壤物理性质:样地Ⅱ体积质量最高,总孔隙度最低,该区域土质最紧实,样地Ⅰ的体积质量最低,总孔隙度最高,该区域土质相对疏松,样地Ⅲ则介于样地Ⅰ和样地Ⅱ之间,样地Ⅱ初始含水率最低,样地Ⅲ则介于样地Ⅰ和样地Ⅱ之间;②土壤养分情况:整个研究区土壤有机质含量处于分4级和5级水平,研究区土壤有机质含量偏低;土壤碱解氮含量处于5级水平,其次是6级,研究区的土壤碱解氮含量较低;土壤有效磷含量处于2级和3级水平,研究区的土壤有效磷含量较高;土壤速效钾含量处于3级水平,其次是2级水平,研究样地的土壤速效钾含量较高。根据土壤状况调查结果,研究样地土壤物理性质偏差,说明土壤持水能力差。土壤养分不足,说明土壤板结,出现地力退化现象。针对研究样地的具体情况,从抚育管理、凋落物处理、为林下植物提供养分、强化土壤管理、科学施肥等方面提出了改善措施。以期实现红枣经济林提质增效的发展目标。
This paper investigates the soil condition of Longshan jujube economic forests in Korla City,and proposes practical and feasible measures to improve quality and efficiency through quarantine based on the current situation.Three sample plots were randomly selected for soil condition investigation in a jujube economic forest research area in Longshan,Korla City.Based on the investigation results,the physical properties and nutrient status of the jujube economic forest soil were analyzed.The results showed that:①Soil physical properties:PlotⅡhad the highest volumetric mass and the lowest total porosity,and the soil in this area was the most compact.Plot I had the lowest volumetric mass and the highest total porosity,and the soil in this area was relatively loose.Plot III was between Plot I and Plot II,with the lowest initial moisture content and between Plot I and Plot II.②Soil nutrient situation:The soil organic matter content in the entire study area is at level 4 and 5,and the soil organic matter content in the study area is relatively low;The soil alkaline nitrogen content is at level 5,followed by level 6,and the soil alkaline nitrogen content in the study area is relatively low;The soil available phosphorus content is at level 2 and 3,and the soil available phosphorus content in the study area is relatively high;The soil available potassium content is at level 3,followed by level 2,and the soil available potassium content in the study plot is relatively high.According to the investigation results of soil conditions,the deviation of soil physical properties in the study site indicates poor soil water holding capacity.Insufficient soil nutrients indicate soil compaction and soil fertility degradation.Based on the specific situation of the research site,improvement measures have been proposed from the aspects of nurturing management and litter treatment,which provides nutrients for understory plants as well as strengthens soil management,and scientific fertilization in order to achieve the development goal of improving the quality and efficiency of jujube economic forests.
