通过田间小区控制试验和大田中取样调查等方法,对小麦根腐病在小麦生长不同阶段的危害损失进行了较详细的研究,明确了小麦根腐病苗腐主要影响田间保苗率、幼苗长势及成穗率等而造成产量损失;成株期的叶腐、穗腐则主要影响粒重而造成大幅度减产;同时穗腐又造成小麦籽粒感病,使种子质量下降而带来损失。
Through field plot control experiment and field sampling survey and other methods, the damage of wheat root rot at different stages of wheat growth was studied in detail. It was clarified that wheat root rot rot affect the seedling protection rate, seedling growth and Spike rate and other resulting in the loss of yield; adult leaf leaves, spike rot is the main impact on grain weight resulting in a significant cut; the same time the ear rot and cause wheat grain disease, so that the loss of seed quality decline.
