摘要
为了减少菜心生产过程中的化学农药施用量,2019—2021年,在广州市南沙区和增城区示范基地内,集成化学、物理机械、生物与农业防治的综合防控技术,如土壤耕沤灭虫、选用抗性优良品种、黄板+性诱剂复合防控、灯光诱控、天敌昆虫防控、“推—拉”防控、生物农药防控、化学农药防治等,并进行技术示范。核心示范面积达210 hm^(2),辐射区在2000 hm^(2)以上,在有效控制菜心害虫的同时,示范区化学农药施用量减少26.3%,增产高达4.76%。
In order to reduce the application of chemical pesticides in the production of flowering Chinese cabbage,from 2019 to 2021,technologies of chemical,physical,mechanical,biological and agricultural prevention and control were integrated in the demonstration bases of Nansha district and Zengcheng district of Guangzhou,including soil retting,selection of resistant cultivars,yellow board+sex attractant compound prevention and control,light inducement control,natural enemy insect prevention and control,"push-pull"prevention and control,biological pesticide prevention and control,chemical pesticide prevention and control.And demonstration of technology was conducted.The core demonstration area was 210 hm^(2),and the radiation area was more than 2000 hm^(2).While effectively controlling flowering Chinese cabbage pests,the application of chemical pesticides decreased by 26.3%and the yield of cabbage increased by 4.76%.
