In order to prevent wheat stem lodging and to fertilize precisely, the experiments on the influence of phosphate and potash fertilizers on mechanical properties of wheat stem were performed with Zhengzhou-wheat 9023 as an object. Mechanical properties (such as flexural strength and flexural rigidity) of second base inter-node were measured by six treatments at five growth stages of wheat, which were jointing stage, booting stage, flowering stage, grain-filling stage and maturity stage. Nonmetallic material testing machine was used in the experiments.
