据统计昌吉市今年冬麦越冬死亡面积达1.5万亩,其中三工乡占1万亩左右。 为此我实地做了调查研究,证明三工乡越冬小麦大面积死亡的原因系雪腐病害,病原物是真菌中担子菌,病株基部有许多小米粒大小的黑点——担子菌核,可以确诊。去冬雪厚,未刮大风,积雪均匀覆盖麦田,今春气温回升慢,融雪期长,给担子菌大量繁殖造成有利环境条件,凡是播种期早,重茬种植,未灌冬水的地块死亡愈重,相反播种期迟,倒茬并冬灌的地块,冬麦基本无
According to statistics, Changji City winter wheat winter wintering area of 15,000 mu, of which three workers accounted for about 10,000 acres. To this end, I did a field survey to prove that the cause of large-scale death of winter wheat in Sangong Township is caused by snow rot disease. The pathogen is the fungus in the basidiomycetes, the base of the diseased plant has many small grains of black spots - basidiomycetes, Can be diagnosed. Winter thick snow, not windy, covered with snow uniform coverage of wheat fields, the temperature rise slowly this spring, melting a long period of heavy basidiomycetes caused favorable environmental conditions, those who sown early, cropping, irrigated water plots of death The heavier, on the contrary late sowing date, inverted cropping and winter irrigation plots, winter wheat basic no
