不同土壤改良剂对油莎豆生长及风沙土速效养分含量的影响
Effects of Different Soil Amendments on the Growth of Cyperus esculentus and the Content of Available Nutrients in Aeolian Sandy Soil
摘要
Abstract
[Objective]Aeolian sandy soil is a young soil developed from aeolian sandy parent material,with low fertility and weak ability to retain water and fertilizer.Using modifiers to improve the fertility of aeolian sandy soil is a rapid means to transform it into farmland.Effects of different modifying materials on the physical and chemical properties of aeolian sandy soil and on the crop growth were studied as the basis for the development of soil amendment materials.[Method]In this study,aeolian sandy soil and Cyperus esculentus were used as the research objects,and five kinds of amendments,such as organic fertilizer,biochar,phosphate rock powder,polyglutamic acid and humic acid,were used for pot experiments.[Result]Results showed that biochar caused the greatest increase in leaf length and chlorophyll contents of Cyperus esculentus,which were 60.67 cm and 76.70,respectively.Polyglutamic acid brought the greatest increase in the tiller number of Cyperus esculentus,reaching 12.In addition,the physical and chemical properties of aeolian sandy soil changed significantly under the treatment of different modifiers.Organic fertilizer treatment had the best effects on the increase of organic matter,available phosphorus and available potassium in sandy soil,which were 5.77 g/kg,158.60 mg/kg and 277.27 mg/kg,respectively.Humic acid treatment had the best effect on the increase of alkali-hydrolyzed nitrogen contents and soil cation exchange capacity of aeolian sandy soil,which were 34.53 mg/kg and 3.33 cmol/kg,respectively.[Conclusion]Among different amendments,biochar had the best effect on the growth of Cyperus esculentus,but organic fertilizer had the best effect on the improvement of available nutrient contents in aeolian sandy soil.关键词
