摘要
2013—2022年连续10年间,开展了茎用莴苣褪绿心腐病综合防控技术区域试验和生产示范,共建立试验和生产示范点43个。结果显示,试验示范区莴苣产量3584.5 kg/667 m^(2),每667 m^(2)比对照增加476.9 kg,增产15.3%;示范区比对照每茬减少喷施化学农药3~4次,使用量减少26.9%;茎用莴苣褪绿心腐病株发病率控制在3%以下,防控效果达90.43%。该技术在大幅提高种植效益的同时减少了农药用量,提高了莴苣的品质,具有显著的经济、社会和生态效益。
This study conducted the demonstration production and regional test about a comprehensive prevention control technology of lettuse chlorotic leaf rot disease(LCLRD)from 2013 to 2022,and established 43 experimental and production demonstration sites.The test results showed that the lettuce yield in the trial demonstration area was 3584.5 kg/667 m^(2),an increase of 476.9 kg/667 m^(2),and a 15.3%increase compared to the control.The trial demonstration area reduced chemical pesticide spraying 3-4 times per crop compared to the control,and reduced chemical pesticide use by 26.9%.The incidence rate of LCLRD was controlled below 3%,and the prevention control effect reached 90.43%.The technology greatly improved the yield of cultivation while reduced the use of pesticides,improved the quality of lettuce,and had significant economic,social and ecological benefits.
