Study on Comprehensive Green Control Technology for Major Diseases and Pests of Photinia in Guiyang Area
The comprehensive green control technology of the main diseases and pests of Photinia in Guiyang area was analyzed,and the application effect of the comprehensive green control technology was summarized.A Pho-tinia planting sample plot in Guiyang was selected and divided into different treatments according to the differ-ence of green control measures of pests and diseases:conventional control technology(Tl),basic green control technology(T2)and comprehensive green control technology(T3).The practical results were analyzed after control.The results show that compared with T1 treatment,the disease rate of T3 treatment in 2021,2022 and 2023 was re-duced by 32.11％,29.23％and 60.29％,respectively.The effect of T3 treatment was the most obvious.The health evaluation analysis of the three treatments showed that the structural index,vitality index and stability index of T3 treatment were superior to the other two treatments.The species number in shrub layer and herbaceous layer in-creased after pest control,and the new advantage of T3 treatment was more obvious.The overall growth of Pho-tinia in Guiyang area is good.According to the existing diseases and pests,the effect of comprehensive green con-trol technology is better than conventional control technology and basic green control technology,which can re-duce the rate of diseases and pests of Photinia,improve the health degree of forest area and increase the number of new species in the understory vegetation.
