在大、小麦育种和品种鉴定中,抗倒伏能力是一个必须鉴定的内容。而抗倒伏能力的强弱,决定于麦秆的强度和株高。但过去缺乏测定麦秆强度的仪器,往往采用一些笼统的词句,如抗倒伏强,弱等来描述,或者根据倒伏的角度,把倒伏程度分为四级来鉴定。上述这两种方法鉴定结果的误差大,不能确切地反映

In large, wheat breeding and variety identification, lodging resistance is a must identify. The strength of lodging resistance, determined by the strength and height of wheat straw. In the past, however, there was a lack of instruments for measuring the strength of straw, which were often described in terms of strong and weak lodging resistance or the like, and the degree of lodging was divided into four levels according to the lodging angle. The errors of the above two methods’ identification results are large and can not be exactly reflected
