早在六十年代,我省开始普遍施用磷肥。大量事实证明,在水稻栽培管理中,不同土壤施用磷肥的反应不同,水稻也呈现不同的增产效果。为了深入了解磷肥效应不同的原因,为合理施用磷肥寻求理论依据,我们对本省几种主要水稻土(红黄泥、紫潮泥、灰泥等)进行了测试分析。现将结果概述如下: As early as the sixties, the province began the widespread use of phosphate fertilizer. A large number of facts show that in the rice cultivation and management, the response of different soil application of phosphate fertilizer is different, rice also showed different stimulation effect. In order to get a deeper understanding of the different reasons of phosphate fertilizer effect and to find the theoretical basis for the rational application of phosphate fertilizer, we tested and analyzed several major paddy soils (red, yellow, purple tide, stucco, etc.) in our province. The results are summarized as follows:
