Soil Condition Survey and Suggestions for Improving Quality and Efficiency of Longshan Jujube Economic Forest in Korla City
This paper investigates the soil condition of Longshan jujube economic forests in Korla City,and pro-poses 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 sta-tus of the jujube economic forest soil were analyzed.The results showed that:① Soil physical properties:Plot Ⅱhad 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.PlotⅢ was between Plot Ⅰ and Plot Ⅱ,with the lowest initial moisture content and between Plot Ⅰ and Plot Ⅱ.② Soil 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.
