One of the hedgehogs is that it is very easy for the hedgehog to attract the fruit trees such as peaches, plums, pears and apples. The elephant sucks on the sap of fruit trees, petioles, leaves, flowers and fruits to maintain their life. Causes the leaves to dry off, fruit deformation, a great impact. Second, the tannic acid substances secreted by hedgehogs have a greater inhibitory effect on the growth of most fruit trees, especially pears and apples. Can cause fruit trees to significantly reduce or not result. Third, the deciduous anthrax bacteria on the hedgehog can also infect pears, apples, etc., resulting in a large number of fallen leaves.
Paulownia is susceptible to purple feather disease because many fruit trees, whether seedlings, saplings or adult fruit trees, suffer from disease, resulting in yellowing of the leaves, dry, and even the death of the whole plant. Paulownia is the wintering ground of the purple feather pathogen. .
Cypress cypress and pear tree can not coexist with the same place, because the pear disease pear rust disease damage the pear shoots, petioles, leaves, fruit stalks and young fruit, resulting in fruit atrophy, fruit deformation, rot and fruit drop; and cypress, especially It is the overwintering place of pear rust fungus. In the spring season, the overwintering bacteria will return to the pear trees with the wind and continue to multiply and harm the pear trees. The cypress and the grape cannot coexist. When both are planted together, the fruit of the grape is not easy to ripen and cause losses.
Because the walnut tree leaves the secretion of walnut leaves after the rain, dripping into the soil will cause harm to the apple root, inhibit growth, so the apple orchard should not be planted around the walnut tree.
The spruce of the pine trees will be seriously damaged by the spores of the pine trees floating in the spring or summer in the spring. In particular, the pear trees suffer most. Pine spores can cause macules and bristly clusters in leaves and fruits of pears and cause malformation of fruits, severely reduce fruit setting rate, reduce yield and quality, and affect economic efficiency.
The banyan tree near the eucalyptus vineyard should not be planted because the banyan tree is a tree that is preferred by Citrus sinensis and brown hornbill. The planting of eucalyptus will induce a great deal of feeding and reproduction of the beetles, which will in turn seriously damage the fruit trees. In addition, the secretion of eucalyptus roots is very harmful to grapes, which can easily lead to the reduction of grapes or even the death of whole plants.
