1983—84年研究结果表明,矮秆小麦早衰是由于其叶片密集,生态环境不良,后期养分偏低,碳氮比失调为病菌入侵造成了有利条件所致(《陕西农业科学》85年2期)。在此基础上,我们又对矮秆小麦腊熟期前在类似生态环境条件下并不出现早衰现象及以矮秆小麦在开花、灌浆期养分水平和促进日衰的病害等问题作了进一步研究。
The results of 1983-84 study showed that the premature decline of dwarf wheat was due to its dense leaves, poor ecological environment, low late nutrients and imbalance of carbon / nitrogen ratio resulting from favorable conditions for pathogen invasion (Shaanxi Agricultural Sciences, 1985, No. 2 ). On this basis, we further study on the phenomenon that pre-ripening date of dwarf wheat before ripening under similar ecological environment does not appear premature aging and dwarf wheat in the flowering, grain filling stage and promote the decline of diseases and other issues .
