The invention belongs to the technical field of agricultural planting, and discloses a green comprehensive prevention and control method for the main pests of asparagus in southern greenhouses. Insect lamp traps and kills insects. The flame high-temperature disinfection technology of soil for clearing gardens of greenhouse asparagus in winter can prevent and control diseases, insects and weeds from the source; the improved sweet and sour liquid can achieve the killing of pests without adding pesticides such as trichlorfon, and at the same time It has better insect attraction and can avoid the problem of faster volatilization of the solution under high temperature conditions. Combined with 385nm violet solar LED lights to kill Spodoptera litura, Spodoptera exigua and other adults, supplemented by yellow/blue armyworm boards The trapping and insect-proof net barrier technology greatly reduces the number of pesticide spraying, reduces the use of chemical pesticides, ensures high yield, high quality and green safety of asparagus, and realizes the reduction of pesticides and the increase of efficiency. |
