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 effect of sodium cyanamide - solar combined disinfection soil method on controlling celery, cucumber and eggplant root knot nematodes was tested. The results showed that when pre-planting calcium cyanamide - solar soil disinfection, pre-planting cyanamide calcium - solar soil disinfection + planting avermectin 1000 times irrigation, pre-planting cyanamide calcium - solar soil disinfection + planting Avermectin 500 times irrigation of root celery root knot nematode disease prevention and control of the field were 69.30%, 85.96% and 89.48%. The average plant height and fresh weight per plant of celery in the soil treated with ammonium cyanamide were significantly higher than those in the untreated control and increased by 30% -79% and 107% -185%, respectively. Cyanamid calcium - solar soil disinfection of cucumber root-knot nematode disease control effect reached 60.44%, eggplant root-knot nematode disease control effect was 55.92% to 68.29%.
