我区各地几乎都存在着青稞的倒伏现象,尤其是当地品种,一般表现杆软。容易倒伏;另一种是田间密度过大,栽培管理粗放,特别是因氮肥使用不当而引起的倒伏问题更为突出。青稞倒伏后群体郁蔽,湿度增加,光合作用减弱。但是,无论哪种原因引起的倒伏,都不利于其穗、粒、重之间的调协发展,而且易感锈病。这已成为青稞高产稳产中的限制因素。为此,我们针对青稞高产倒伏及其影响产量等问题,进行了试验和调查分析。
Almost all parts of my area of barley lodging phenomenon, especially the local species, the general performance soft rod. Easy to lodging; the other is the field density is too large, extensive cultivation and management, especially due to improper use of nitrogen caused by the lodging problem is more prominent. After the barley lodging group Yu shelter, humidity increased, photosynthesis weakened. However, no matter what kind of cause of lodging, are not conducive to its spike, grain, heavy mediation between the development and susceptibility to rust. This has become a barley high yield and stability in the limiting factor. For this reason, we conducted experiments and investigations on the problems of barley high yield and its impact on yield and other issues.
