摘要:
南方红壤地区是我国热带和亚热带经济及粮食作物的重要生产基地,开展不同措施红壤坡地土地生产潜力关系的研究,对指导人们合理开发利用该类土壤资源具有重要的现实意义和科学价值。基于气候-土壤生产潜力计算模型,以土壤养分作为修正函数,综合考虑气候因子和土壤因子对土地光温生产潜力的影响,以红壤坡地3种生态治理措施和裸露坡地为研究对象,以实测的不同措施坡地土壤化学性质为基础,提出了红壤坡地土地生产潜力计算方法。以柑橘为例,定量分析了不同措施对红壤生产潜力的影响,研究结果显示前埂后沟梯壁植百喜草的梯田果园(措施Ⅱ)土地生产潜力最大,较裸露地坡地提高了300多倍。研究结果表明,由于南方红壤地区降水多,水分不是作...
Abstract:
The redsoil region of the tropical and subtropical area, located in South China, is one of important cases for tropical cash and food crops base within tropical and subtropics regions. Conducting the research on potential productivity of slope with red soil is very useful to develop and utilize the soil resources. Based on the EPIC (Environmental PolicyIntegrated Climate) model. A computation method for potential productivity of slope land with red soil is set up in this paper. Soil nutrients are taken as the modified function in the method. With the impacts of weather and soil on thermal production potential considered, three kinds of slop with different treatments and bare slop are studied in the paper. The paper presented the impacts of different treatments on the productivity the slope with red soil. And The results indicated that land potential productivity under measureⅡ(horizontal terraces of orchards with Bahia grass planted on the walls and mounds before but a ditch behind)was the highest,which was 300 times higher than that of bare slop. The results also revealed that water is not the limited parameter for land productivity in this region since the precipitation is enough for crop. The capacity to meet the crop needs of soil nutrients decreased with the increase of soil erosion, and available phosphorus is the key parameter for the crop growth.
