摘要
土壤对磷的固定能力很强,也就是说在土壤中建立起了一个"磷库"。如果有效磷的累积利用率都达到70%-80%,则磷肥施用量可以逐步降低,能够节省大量的资源、能源和资金。本文主要分析了在我省高浓度磷复肥的应用技术分析。
Soil has strong fixation capacity to the phosphorus,that means to built a ＂phosphorus stores.＂ If the accumulated phosphorus utilization reaches 70%～80%,while P fertilizer can be gradually reduced which can save a lot of resources,energy and money.This paper analyzes the application technology of high concentration compound fertilizer in Heilongjiang province.
