氰氨化钙-太阳能消毒土壤防治蔬菜根结线虫病研究

Studies on Soil Treated by CaCN_2 and Solarization to Control Meloidogyne spp. Infecting Vegetable Crops

对氰氨化钙-太阳能联合消毒土壤法防治芹菜、黄瓜、茄子根结线虫病的效果进行了试验。结果表明,定植前氰氨化钙-太阳能土壤消毒、定植前氰氨化钙-太阳能土壤消毒+定植时阿维菌素1000倍液灌根、定植前氰氨化钙-太阳能土壤消毒+定植时阿维菌素500倍液灌根对芹菜根结线虫病田间防治效果分别为69.30%、85.96%和89.48%。氰氨化钙土壤处理区芹菜的平均株高和单株鲜重均极显著高于不处理对照区,分别较对照增长30%～79%和107%～185%。氰氨化钙-太阳能土壤消毒对黄瓜根结线虫病的防效也达到了60.44%,对茄子根结线虫病的防效为55.92%～68.29%。

The control experiment of CaCN_2 to Meloidogyne spp. in Shandong province was conducted during 2002～2004. The results showed that the control effect to celery root knot nematode was 69.30%～89.45%, 60.44% to cucumber, and 55.92%～68.29% to eggplant.
