Effects of different mowing time on rhizosphere soil nutrients and salt-based ions of Cyperus esculentus in northern and southern Xinjiang
[Objective]The investigation was performed to explore the effects of different mowing time on rhizo-sphere soil nutrients a salt-based ions of Cyperus esculentus in northern and southern Xinjiang.[Method]C.esculen-tus was planted in Shache City of southern and Fukang City of northern Xinjiang on May 15,2021.The rhizosphere soil samples were collected on 78,91,106,124 days after seed sowing.The rhizosphere soil nutrients and salt-based ions were analyzed.[Result]The sampling site and mowing time had significant effects on soil pH(P<0.05).Their interaction had significant effects on soil pH,TN,TP,and TK(P<0.05),but had no effects on soil ion content(P>0.05).The contents of TN,TK,AP,and AK in rhizosphere soil of northern Xinjiang were significantly higher than those in rhizosphere soil of southern Xinjiang(P<0.05),but the contents of cations(Na+,K+,Ca2+,and Mg2+)in rhizosphere soil of northern Xinjiang were significantly lower than those in rhizosphere soil of southern Xinjiang(P<0.05).In northern Xinjiang,the pH was negatively correlated with the contents of AK and Cl-(P<0.05),and posi-tively correlated with the content of HCO3-(P<0.05).In southern Xinjiang,the pH was negatively correlated with the content of AK(P<0.05),and positively correlated with the contents of Na+and Cl-.[Conclusion]Mowing time changed the contents of TK,AK,and AP and pH value in the rhizosphere soil of southern and northern Xinjiang,and changed the content of Cl-in the rhizosphere soil of northern Xinjiang.The interaction between mowing time and sampling site(northern Xinjiang)had the greatest effect on soil TN and TP.This study provided a theoretical basis for the promotion of actual production of C.esculentus in Xinjiang region.
