红壤因自然条件和培肥管理措施不同而具有不同肥力。研究红壤耕地肥力特性、肥力指标,不但可以了解肥力演变过程,并且能为定向培肥熟化红壤提供依据。为此,1978—1980年组织了我省红壤科研协作组的十个单位,在我省南、中、北十个地点,进行了三年定位试验。在各个试验点,选择同一母质的高、中、低三种不同肥力的红壤耕地,设四个处理:(1)对照(不施底肥);(2)磷肥每亩00斤;(3)厩肥每亩4000斤;(4)磷肥100斤+厩肥4000斤。着重研究不同肥力红壤对磷肥和有机肥的反应,以及不同肥力红壤的肥力特性与作物产量的关系,同时探索
Red soil has different fertility due to different natural conditions and fertilizer management measures. Study on the red soil cultivated land fertility characteristics, fertility indicators, not only to understand the process of fertility evolution, and can provide the basis for targeted fertilization and maturation of red soil. To this end, from 1978 to 1980 organized ten units of the red soil scientific research cooperation group in our province, and carried out a three-year positioning experiment in ten locations in the south, middle and northern part of our province. At each test point, three high, medium and low red soil cultivated land with the same parent material were selected and set up as four treatments: (1) control (without base fertilizer); (2) 200 kg of phosphate fertilizer per mu; (3) 4000 kg per mu; (4) 100 kg of phosphate fertilizer + 4 kg of manure. Focus on different fertile red soil on the response of phosphate and organic fertilizer, and fertility characteristics of different fertile red soil and crop yield, while exploring
