| 中文摘要: |
| 生姜癞皮病在山东7月开始发病,8月中旬至9月中旬为盛发期。病株植株矮小、茎细、分枝少,叶色变淡,根茎表皮疣裂,根系腐烂,产量品质降低。病原物为南方根结线虫。砂质土壤、连作重茬、过量施钾肥均可加重该病的发生。 |
| 英文摘要: |
| The development of ginger bark cracking disease in the major planting areas of ginger were investigated in June in Shandong Province. Ginger bark cracking disease occurred in the middle of July,and got worse from the middle of August to the middle of September. This disease led to lower height, slim stem fewer branches and shallow color of the leaves. The typical symptoms were root - rotting and rhizome splitting. Ginger bark cracking disease also caused reduction of the yield and quality of gingers. Root-knot nematode was identified as the infection pathogen. Sandy soil, sequential planting and excessive potassium fertilization could aggravate the disease. This was the first report about gingers infected with root - knot nematode in China. |
