1. Avoid planting pine trees Because the spores of pine trees floating in the wind in the spring and summer will seriously damage the fruit trees, especially the pear trees are the most affected. Pine spores can cause macules and bristly clusters in the leaves and fruits of pears and cause the fruits to become deformed, which severely reduces the fruit setting rate and reduces the yield and quality. Therefore, do not plant various pine trees around the orchard where pear trees are planted.
2. Avoid planting cypress and cypress trees can not coexist with the same place, because the pear disease rust (Brassica disease), the main disease of pear, damages the new shoots, petioles, leaves, stalks and young fruits of pear trees, resulting in atrophy of the fruit branches, fruit deformation, Decay and fruit drop; while Cypress, especially Cypress and Cypress, is the wintering place for Pear rust. 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, because if the cypress is planted near the grape, the fruit of the grape will not mature.
3, bogey planted hedgehog (acacia) First, the hedgehog is very easy to attract elephants (stupid pest) harm peach, plum, pear, apple and other fruit trees. The stink bug absorbs the sap in the shoots, petioles, leaves, flowers and fruits of the fruit tree to maintain its life, often causing the leaves to dry off and the fruit to be deformed and being inedible; the second is that the tannins secreted by the stings have a greater effect on the growth of various fruit trees. The large inhibitory effect, especially pears and apples, is more severely inhibited, which can lead to a significant reduction of fruit trees or no results at all. Third, deciduous anthrax pathogens on acacia can also infect pears, apples and other fruit trees, resulting in a large number of fallen leaves.
4, bogey plant Paulownia Because many fruit trees, whether seedlings, saplings or adult fruit trees, are susceptible to purple feather disease, fruit tree disease, resulting in yellow leaves, dry, and even the whole plant death. The paulownia is the wintering ground of the purple feather pathogen.
6, bogey planted walnuts (walnuts) because the walnut leaf secretions of walnut seedlings after rain, drip into the soil and produce harm to the apple roots, inhibiting their growth, so the apple orchards should not be planted around the walnut.
5. Avoid planting eucalyptus, especially oranges, and avoid planting of eucalyptus near vineyards, because eucalyptus is a tree that is favored by orange star goslings and brown days beetles. Planting eucalyptus will induce a large number of calfs to feed and multiply, and it will seriously harm citrus. In addition, the secretion of eucalyptus roots is very harmful to grapes, which can easily lead to a reduction in the yield of grapes or even the death of whole plants.
