Oasis Soil Macronutrients Research

The soil is the material basis of human survival and precious natural resources.The soil nutrient is essential for animals and plants growth and quality of cropsproduction. Such as Soil erosion, salinization, desertification phenomenon seriouslyincrease, to improve soil productivity, pay attention to the basic construction offarmland, the reasonable fertilization and crop production combined with quality,strengthen soil nutrient is necessary premise of achieve high yield, high efficiency,high quality agriculture and sustainable development.This paper based on the Soil analyze, Soil fertilizer, Oasis soil books useXinjiang Shanshancounty’s Shanshan town, Qiketai town, Lianmuqin town, Lukeqintown, Tuyugu town, Ertang, Kekeyar etc not continuity and distribution is moretypical oasis soil as the research object, Collecting a total of197soil samples Use ofstatistical software for the study area of soil organic matter, nutrient content of thewhole of comparative analysis, the following major conclusions:1. The macronutrient contains of soil in study area is: Total nitrogen arebetween0.01～2.58g/kg, average0.60g/kg, less than ourcountry’s soil total nitrogen,the variation coefficient was0.76;solution nitrogen are between1.4~297.5mg/kg,average26.76mg/kg, is deficient; total phosphorus are between0.09~7.21g/kg,average1.71g/kg, higher than ourcountry’s soil average nitrogen contents, thevariation coefficient was0.74; Available phosphorus are between0.34~28.85mg/kg, average6.84mg/kg, is deficiency; total potassium are between0.13~8.71g/kg, average2.38g/kg, is higher than ourcountry soil’s average potassium contents,the variation coefficient was0.72; available potassium are between11.99~783.57mg/kg, average214.46mg/kg, is abundant, the variation coefficient was0.3; Organicmatter in0.56%~1.44%, less than our country’s soil organic matter contents; SoilpH between7.39～8.68, average8.06, is alkaline soil; Soil porosity are between24.37%~48.77%, average38.04%, soil particles is too small, high compactness.2. A soil nutrient contains distribution is: on different landscape’s, transitionalzone lower than the oasis; on land use types, cultivatedland and grassland less thanforest land; about Soil profile, surface contents higher than middle and lower level;on altitude, with the increase of altitude soil nutrients content also increased; Relatedanalysis prove that, soil nutrient contains with organic matter correlation is very good,have a positive correlation, correlation coefficient was between0.21and0.72, isproof that organic matter can increase soil nutrient contains theory. To improve soil 3. Improve soil nutrient: Because this area soil be an alkalescency soil, sochoose to use to lead sour material first such as list the quality sulphur, ferric sulfate,aluminum sulfate to lower soil alkalescency; While use Fertilizer first to Chooseacidity fertilizer such as the nitrogen fertilizer(AN, UAN), and phosphorous fertilizer(TSP)(MAP);Plant a green manure plants such as Sophora alopecuroides, Medicagotianschanica is best choice to improve this the area soil organic quality content, loweralkalescency, and soil materialization property.
