Trees that have adverse effects on fruit trees

In the development and production of fruit trees, if we do not scientifically grasp the environmental requirements of the development and production of fruit trees on the surrounding "ecological forests" and blindly develop planting, the fruit trees will spread through the "sources of surrounding forests" and induce a variety of pests and diseases. Therefore, in the economic development of the fruit trees, they should be kept away from the following trees that transmit pests and diseases.

Artichokes are also known as hedgehogs. Artichokes grow faster and their wood quality is good, but they cannot be planted around orchards. The reason is that the artichokes are prone to attract worms such as cockroaches, causing damage to fruit trees. Grasshoppers are common pests in the production of forest fruit and crops, which can cause dry and dead leaves of fruit trees. Fruit deformation can cause loss of food value, and the number and quality of products can be seriously reduced. In addition, artichoke is an overwintering site for anthracnose mycelia of the Rosaceae family, such as apple trees and pear trees. Planting artichokes next to these fruit trees will cause the spread and harm of anthrax.

The pine pollen of pine can cause harm to pear trees that are two or three hundred meters away, causing macular, bristly clustering of pear leaves, and even causing fruit deformity, reducing the rate of results, and seriously affecting the quality and yield of pears. Therefore, when developing pear orchards, the location of the pear orchard must be more than 500 meters from the pine forest.

Paulownia paulownia is a common fast-growing economic forest. According to the research, paulownia is the main host of the purple striae pathogen in the roots of fruit trees. Planting paulownia in orchards is conducive to the spread of purple feather disease, and seedlings, saplings and adult fruit trees can suffer from this disease. Those with mild conditions grow poorly, grow weaker, their leaves turn yellow and fall ahead of their fallen leaves, and those with severe disease begin to dry up from the thin branches and eventually cause the death of the whole plant, causing greater damage to the fruit trees.

There are also many types of cypress trees in China, such as Cypress (Sabina chinensis), Platycladus orientalis, Cypress, Cypress, Cypress, and Red Cedar. There is such a saying in forestry that "Pear and cypress are crickets and must be planted on a business trip." This is because the pathogenic microbe of pear rust is a fungus. After the disease damages the pear tree every year, it also needs to be transferred to cypress to get through the winter. The year continues to harm the pear tree.

Eucalyptus eucalyptus is a common economic tree. There is an organic compound in the root exudates. Grapes are very sensitive to the reaction of this compound. Once infected with this secretion, the grape's root system will wither until it dies. Studies have shown that the distance between eucalyptus and grapes is a few meters away from this cross-over effect.
