| 摘 要： | 通过对冀东冬小麦根腐病的初侵染来源进行研究 ,结果表明 :冀东地区冬小麦根腐病的初侵染来源主要是种子带菌和土壤带菌 ,田间病残体和杂草也是比较重要的初侵染来源。通过对不同轮作形式的麦田土壤的病菌数量进行系统测定 ,结果表明 :小麦不同生长期 ,土壤中根腐病菌数量不同 ,小麦播种前土壤中病菌含量低 ,乳熟期病菌含量最高。小麦—玉米—小麦轮作形式下 ,土壤中病菌含量较高

| Abstract: | The initial infection origins of wheat root rot in the eastern parts of Hebei province were studied The results showed that the initial infection origins were mainly the seeds and soil which carried germs, and the more important origins were the invalid plants and weeds Through systematical measurement of the quantity of germs of wheat soil in different crop rotation types, the results showed the quantity of root rot germs in soil is different in different growing periods The quantity of germs is less before sowing The content of germs is higher during the milky ripe period If wheat corn wheat were rotated, the content of germs within the soil is higher |
