Application Effects of Different Soil Conditioner on Improving Acidified Soil,Quality and Yield of Cucumber
In order to study the effects of soil conditioners on soil nutrients and cucumber yield and quality,the experiment was carried out in severely acidified cucumber greenhouse.Compared to the control group,the application of silicon-potassium soil conditioner and humic acid soil conditioner significantly increased the content of organic matter in soil by 7.27%and 8.18%,respectively.Compared to the traditional soil conditioner,the application of humic acid soil conditioner increased the content of available phosphorus and available potassium by 6.40%and 4.86%,respectively,and decreased significantly the bulk density of the soil.Compared to the silicon-potassium soil conditioner,the Vc content,soluble solids and soluble sugars were increased by 7.53%,7.33%and 7.79%,respectively.The yield and quality of cucumber were significantly increased when humic acid soil conditioners were applied,and the yield was the highest.In conclusion,humic acid soil conditioner could effectively improve the acidified soil,increase the yield and quality of cucumber,and be suggested to use in the field of soil improvement.
