木醋液及其配施螯合钙对盐碱土土壤性质和棉花幼苗生长的影响
Effects of wood vinegar and chelated Ca combined application on soil properties and growth of cotton seedlings in saline-alkali soil
摘要
Abstract
In order to investigate the impacts of wood vinegar liquid and its combined application with chelated calcium on the properties of saline-alkali soil in Xinjiang and the growth of cotton seedlings,an indoor pot experi-ment was carried out.A total of seven treatments were set up,namely the application of distilled water(CK),the application of wood vinegar liquid at 150(M1),300(M2),and 600 kg·hm-2(M3),and the application of a combination of wood vinegar liquid and chelated calcium at 150(T1),300(T2),and 600 kg·hm-2(T3).The results showed that,(1)Compared with the control group,both the application of wood vinegar liquid and the combined application of wood vinegar liquid and chelated calcium could significantly reduce the content of water-soluble total salt in the soil,with a reduction range of 8.75％～54.10％.The content of soil available phosphorus(Available-P)increased significantly by 32.25％～86.95％,and the content of soil available potassium(Available-K)increased significantly by 8.80％～14.96％.The contents of soil polyphenol oxidase(S-PPO)and soil alkaline phosphatase(S-AKP)increased significantly by 5.16％～16.65％and 3.08％～45.90％,respectively.The plant height,stem diameter,and fresh weight of cotton seedlings increased by 5.66％～53.81％,9.80％～45.61％,and 3.21％～124.78％,respectively.(2)In comparison with the sole application of wood vinegar liquid,the com-bined application of wood vinegar liquid and chelated calcium could effectively promote the reduction of water-solu-ble total salt in the soil.The lowest content was 3.54 g·kg-1,which was 54.10％lower than that of CK.The con-tents of soil available phosphorus and soil available potassium were the highest under the T2 treatment,reaching 65.30 g·kg-1 and 174.00 g·kg-1,respectively,showing an increase of 88.10％and 19.70％compared with CK.The activity of S-AKP was the highest under the T3 treatment,increasing by 45.90％compared with CK.The plant height,stem diameter,and fresh weight of cotton seedlings were the highest under the T2 treatment,measuring 8.60 cm,11.80 mm,and 3.27 g,respectively.(3)Through the entropy weight method analysis,it was found that the combined application of wood vinegar liquid and chelated calcium had a better effect on improving saline-alkali soil than the sole application of wood vinegar liquid.The T2 treatment was superior to other treatments,ranking first in the comprehensive evaluation.The optimal application rate was 300 kg·hm-2.关键词
