不同处理时长对棉隆土壤处理防治芹菜根腐病防治效果的研究

本次试验针对棉隆30kg/亩土壤处理方法,设置了两个处理时长,旨在研究通过棉隆相同浓度条件下土壤处理不同处理时长对芹菜根腐病的防治效果。结果表明:经过124 天覆膜土壤处理的芹菜地生长82 天后,芹菜死亡率为8.9%,产量为6954.5kg/亩;经过10 天覆膜处理的芹菜地经过相同生长期后芹菜的死亡率为18.1%,产量为6219.4kg/亩;对照经过相同生长期后的死亡率为54.5%,产量为2927.7kg/亩。因此,说明棉隆覆膜对芹菜根腐病的防治效果与土壤处理时间长短存在直接关系。系统性研究棉隆

Study on the Effect of Different Treatment Duration on the Preventionand Treatment of Celery Root Rot in the Soil of Mianlong

In this experiment, two treatment durums were set for the soil treatment method of 30kg/ mu ofCottonwood, in order to study the prevention and treatment effect of different treatment durums on the root rotof celery under the condition of the same concentration of Cottonwood. The results showed that after 82 daysof growth, the mortality rate of celery was 8.9% and the yield was 6954.5kg/ mu. The mortality rate of celerywas 18.1% and the yield was 6219.4kg/ mu after 10 days of film-covering treatment. After the same growthperiod, the mortality rate was 54.5% and the yield was 2927.7kg/ mu. Therefore, there is a direct relationshipbetween the prevention and treatment of celery root rot and soil treatment time. Systematic study on the effectof soil treatment on the control of celery root rot is of great significance for the sustainable control of celerydisease.
