研究工作把小麦和土壤综合为一个统一系统。在保障磷素营养充足的条件下,利用1~5N示踪,探讨小麦——土壤系统N平衡及小麦对N素的吸收利用和物质生产,并试图把小麦、土壤、肥料和措施综合为一个完整的栽培体系,进行小麦合理施(N)肥运筹规律的研究。 Research has integrated wheat and soil into a single system. Under the condition of sufficient phosphorus nutrition, 1 ~ 5N tracing was used to explore the N balance of wheat-soil system and the absorption and utilization of N and its production by wheat. At the same time, wheat, soil, fertilizer and measures were tried to be integrated into one A complete cultivation system for wheat fertilization (N) fertilizer research on the law.
