为分析小麦生育后期基部节间弯曲力学特性与氮磷钾含量的关系,测试了不同时期茎基部节间的抗弯刚度、弯曲强度、弹性模量、惯性矩等弯曲力学特性以及茎秆氮、磷、钾含量.结果表明,扬花期抗弯刚度最大,灌菜期弯曲强度最大.在一定范围内,氮含量越高,抗弯刚度越大;钾含量越高,弹性模量值越小;氮含量越高,惯性矩越大.

Relationships between stem bending properties such as bending rigidity, bending strength, elastic modulus and moment of inertia and contents of nitrogen, phosphorus and potassium in late growing period in wheat were studied in this study.The results showed that value of bending rigidity was the maximum at anthesis.Value of bending strength was the maximum at grain-filling stage.The more nitrogen content wheat stem had, the bigger the flexural rigidity was.The more potassium content wheat stem had, the smaller the elastic modulus was.The more nitrogen content wheat stem had, the bigger the moment of inertia was.
