Abstract:

In order to explore the production performance and soil improvement effect of sweet sorghum in saline-alkali land,Zhongketian 438 sweet sorghum was planted in Southern Xinjiang,and its yield was measured,in addition,0-10 cm,10-20 cm,20-30 cm soil layers were selected on saline-alkali land before planting and after harvesting of feed sweet sorghum varieties,and the effects of soil physical and chemical properties,soil ions and soil enzyme activities were measured and compared.The results showed that the total salinity,pH value and electrical conductivity of the soil decreased after the planting of sweet sorghum.Compared with before planting,the contents of Na+,K+,HCO3-,Cl-and SO42- and total potassium,total phosphorus,available phosphorus and available nitrogen decreased significantly,while the contents of Ca2+,Mg2+,total porosity,organic matter,total nitrogen and available potassium increased.The content of Mg2+ in soil cation was highest,and the content of SO42- in anion was the higher than that of Cl-.In soil enzyme activity,the activities of catalase,sucrase and alkaline phosphatase were not significantly different,but the urease activity was significantly different.Compared with before planting,the change of 10-20 cm soil layer in different soil layers was more obvious.The results of correlation analysis showed that there was a significant positive correlation between pH value and total salinity;there was a significant negative correlation between bulk density and pH,total salinity;and a significant positive correlation between sucrase and alkaline phosphatase.The above results showed that the saline-alkali soil in this area is a soil type dominated by Na2SO4,and the cultivation of feed sweet sorghum in the saline-alkali soil in this area could not only harvest high-yield forage grass,but also reduce some ions in the soil to improve soil physical and chemical properties.

Key words: Sweet sorghum, Saline-alkali land, Soil physical and chemical properties, Soil ion, Soil enzyme activity
