加气滴灌和生物炭对盐碱土理化性质和棉花产量的影响
Effects of aerated drip irrigation and biochar on physical and chemical properties of saline-alkali soil and cotton yield
摘要
Abstract
In order to formulate reasonable improvement measures for saline-alkali soil and improve cotton yield and water use efficiency,two drip irrigation methods were set up:unaerated conventional drip irrigation(A0)and aerated drip irrigation(A1),and four biochar application rates:0,12,24,and 36 t·hm-2(B0,B12,B24,and B36).The effects of aerated drip irrigation and biochar on the physical and chemical properties of saline-alkali soil and cotton yield were studied.The results showed that with the increase of biochar dosage,the soil bulk density decreased gradually,which was 8.63％lower than that of the B0 treatment.The soil porosity,pH value,and salt content increased gradually,with an increase of 12.57％,2.62％,and 11.72％,respectively.The soil water content increased first and then decreased,and the increase of the B24 treatment was the largest,reaching 19.24％.Compared with the A0 treatment,the soil bulk density,water content,pH value,and salt content of the A1 treat-ment decreased by 4.71％,9.27％,0.82％,and 4.65％,respectively,and the soil porosity increased by 6.19％on average.Under the combined action of aerated drip irrigation and biochar,the cotton yield increased by 17.17％on average,and the water use efficiency increased by 13.55％on average.关键词
