Effects of rotation systems on physical and chemical properties of soil in continuous Zizania latifolia cultivation
摘要
Abstract
To explore the remediation effects of rotation systems on the degraded soil in the cultivated layer of Zizania latifolia,3 rotation systems of Zizania latifolia-maize,Zizania latifolia-rice,and Zizania latifolia-taro were set up.The aim was to study the impacts of these 3 rotation systems on soil structure,soil nutrients,and other physical and chemical properties of the cultivated layer after long-term planting of Zizania latifolia.The results showed that compared with continuous Zizania latifolia cultivation,the rotation systems of Zizania latifolia-maize and Zizania latifolia-taro could remarkably increase(P<0.05)the soil porosity and raise the proportion of water-stable aggregates(≥2 mm)in the soil.Under the 2 rotation systems,the proportion of water-stable macropores(≥2 mm)increased by 7.68%and 9.00%respectively,and the effective soil pores increased by 28.23%and 21.19%respectively.The rotation systems of Zizania latifolia-maize and Zizania latifolia-taro could significantly increase the soil pH value(P<0.05).After the rotation,the soil pH value increased to a range of 5.79-5.82.The rotation systems of Zizania latifolia-rice,Zizania latifolia-maize,and Zizania latifolia-taro could significantly reduce the contents of soil organic matter,available nitrogen,available phosphorus,and available potassium(P<0.05).All these indicators were maintained within a relatively reasonable range,thus reducing the risk of environmental pollution.In terms of economic benefits,among the three rotation systems,the Zizania latifolia-corn rotation showed the best total benefit,reaching 17 786.5 yuan/667 m².In conclusion,the three rotation systems in this study can improve the physical and chemical properties of degraded soil.In terms of economic benefits,the rotation system of Zizania latifolia-maize performs the best.关键词
