In autumn, these kinds of fruit trees should not be mixed, so that it is inconvenient to manage the orchard, and there is potential harm。So, which fruit trees should not be mixed？ 

      Fruit trees that are not suitable for mixed planting in autumn 

      Peach and pear trees should not be mixed。Reason: When the two are mixed, the occurrence of pear small food worm is more serious。Pear small food worm is the main pest of pear trees, but if the two are mixed, the pear small food worm will harm the peach tip in the early stage and the pear fruit in the later stage。At the same time, when pear trees and peach trees are mixed planted, the spread of scale insects will be aggravated。 

      Apple and pear trees should not be mixed。Reason: Because the pathogen of rust fruit disease lurks in pear trees for a long time, but for a long time, rust fruit disease is easy to infect nearby apple trees, causing great harm to the quality of apples。 

      Apple trees and peach trees should not be mixed。Reason: Compared with apple tree, peach tree growth is relatively large, easy to compete for water and fertilizer in the soil, so that the growth potential of apple tree is weakened, the quality and yield of fruit are affected, and the fruit tree itself is also easy to form "small old trees".。

      Cherry and pear trees and apple trees should not be mixed。Reasons: cherries mature first, pears and apples mature later, the first generation of peach worms, pear flies and peach moth larvae will eat peaches, the second generation of larvae eat pears and apples, if these three kinds of fruit trees are mixed, they will provide rich and continuous food for each generation of larvae, which will aggravate the harm。In addition, the medicine sprayed on apple trees and pear trees cannot be sprayed on cherry trees, which causes inconvenience for management。
