施用牛粪和绿肥对土地整治区玉米产量和土壤理化性质的影响
Effect of application of cow manure and green manure on corn yield and soil physical-chemical properties in land restoration area
摘要
Abstract
The effects of cow manure and green manure on maize yield,soil respiration and soil physical-chemical properties in land restoration area was evaluated through field experiments.The results indicated that the maize yield and thousand-grain mass with cow manure were increased by 7.2%-29.9% and 2.5%-18.2%,respectively compared with the application of chemical fertilizer (CF),while the soil active organic carbon and organic matter contents of cow manure were 5.3%-34.6% and 8.0%-17.6% higher than that obtained in CF.The maize yield and thousand-grain mass were increased by 10.8%-15.6% and 4.5%-8.4% with application of green manure,respectively compared with CF.The content of active organic carbon in green manure was 14.1%-48.6% higher than that detected in CF.In the second year,the content of organic matter in green manure treatment was 7.2% higher than that of CF.The soil respiration rates under cow manure and green manure treatments increased by 20.0%-69.3% compared with CF.CF and green manure could improve the soil bulk density and increase the aggregate ratios of <0.01 mm and 0.05-1 mm fractions,respectively.On the other hand,the cow manure and green manure could decrease the soil total porosity and the capillary porosity.In conclusion,the application of cow manure and green manure in land restoration region could increase maize yield during the two consecutive seasons,which showed a positive response to improvement of soil physical-chemical properties.关键词
