小麦全蚀病发病条件调查研究

调查研究表明，影响小麦全蚀病发生的条件，主要有前作物、肥料类型、品种与播种期。前作物中，玉米最有利于全蚀病的发生，棉花不利于其发生； 肥料类型中单施氮肥或磷肥，病害严重，增施有机肥与氮磷钾配方施肥，可减轻病害；播期的影响，早播的病重，适时晚播的病轻。品种间存在一定程度的抗、耐病性差异，但无免疫与高抗品种。

STUDY ON CONDITION OF DISEASE OF "TAKE-ALL DISEASE OF WHEAT

it indicated that the main infecting factors to "Take-all disease of wheat"are: former crops fertilizer varieties, wheat varieties and planting stage. Corn is the mostbeneficial to "Take-all disease of wheat" and cotton is unfavourable in former crops. UsingN, or p-manure only can emphasize the disease while using more organic manure and using N, P and K-manure in right proportion can lighten it. Earlier planting can rise the disease and suitable later planting can reduce it. There are different resistance or tolerancewhich were found in diferent wheat varieties, but no immure or high resistant varieties werefound.
