玉米是山东荷泽地区主要粮食作物之一,种植面积仅次于小麦。由于地理条件、种植品种和土壤条件的变化影响,近年来玉米较普遍地发生缺锌症,即“花白苗”,亦称“白苗病”。轻者减产10～30％,重者引起玉米绝产,严重影响了玉米的生产和发展。
Corn is one of the major food crops in Heze, Shandong, with the area under cultivation being second only to that of wheat. Due to the change of geographical conditions, planting varieties and soil conditions, zinc deficiency is more common in maize in recent years, namely “Huapaimiao”, also known as “white seedling disease.” Light reduction of 10 to 30%, severe cases of maize caused corn, seriously affecting the production and development of corn.
