近年来,随着小麦单产水平的不断提高,高产与倒伏的矛盾日益突出,倒伏已成为小麦持续获得高产稳产的主要障碍因素。分析小麦倒伏的原因,探讨预防小麦倒伏的有效措施,对于促进小麦生产再上新的台阶具有重要意义。一、小麦倒伏的类型及对产量的影响1.小麦倒伏的类型。小麦的倒伏可分为根倒和茎倒两种类型。根倒即小麦倒伏时一侧的根断裂连根歪倒;茎倒即小麦倒伏时其茎秆倾斜或折断匍匐于地面。根倒
In recent years, with the continuous improvement of the yield of wheat, the contradiction between high yield and lodging has become increasingly prominent. Lodging has become the main obstacle to the continuous and high yield of wheat. Analysis of the causes of wheat lodging and discussing effective measures to prevent wheat lodging are of great significance for promoting wheat production to a new level. First, the type of wheat lodging and the impact of yield 1. The type of lodging of wheat. The lodging of wheat can be divided into root and stem down two types. Roots down when lodging on one side of the root of wheat root fracture collapsed root; stem down that when the stem lodging wheat tilted or broken prostrate on the ground. Root down
