| Abstract: | In order to solve the problem of saline-alkali land improvement in the arid area of southern Xinjiang,the law of soil water and salt transport during spring irrigation with different powder ridge depth and irrigation amount was discussed.In this study,12 treatments,including three furrow depths of S1(40 cm),S2(60 cm)and S3(80 cm),and three irrigation amounts of W1(2400 m3/hm2),W2(3000 m3/hm2)and W3(3600 m3/hm2),were set up in the saline and alkali land test field in Tumushuke city,Xinjiang,with CK(20 cm)as the control,to conduct experiments to analyze the dynamic changes of water content and salt content in 0~150 cm soil layer after spring irrigation.The results showed that spring irrigation could change the distribution of soil water in cotton field,effectively leach and reduce the soil salt content in cultivated layer.Compared with traditional CK tillage,powder ridge tillage could reduce the soil bulk density,increase the soil saturated water content and total porosity.The salt content of 0~100 cm soil layer was lower than that of traditional tillage,and the effect in 0~40 cm root layer soil was particularly significant.The desalting rate of 0~40 cm root layer soil after S1,S2 and S3 irrigation treatment was increased by 24.80%,39.05%and 44.17%,respectively,compared with CK treatment.It is concluded that the depth of powdery ridge and water quota of spring irrigation have obvious improvement effect on the distribution and content of water and salt in cotton field soil. |
