Problems solved by technology

Although walnut trees have strong adaptability and few pests and diseases, the damage caused by diseases and insect pests is relatively serious. If comprehensive control measures cannot be taken in time to reduce the occurrence of diseases, the walnut harvest will be reduced or even stopped, resulting in economic losses.
However, walnut black spot and walnut anthracnose, and pests such as chafers and longhorns are also easy to cause damage to them. It is particularly important to find corresponding control methods by distinguishing the impact of different pests on walnut trees.

Abstract

The invention relates to the field of walnut cultivation and planting, in particular to a diseases and insect pests prevention and treatment method for walnut. By adopting a mixed fertilization mannerof plant ash, potassium fertilizers and phosphate fertilizers, the fertility of walnut is satisfied, bacteria in the soil can be preliminary killed by plant ash, and soil structures can be also improved by plant ash, so that the mixed fertilization manner is relatively conducive to walnut tree growth. By preventive spraying of pesticides before germination, flowering and fruiting, targeted killing of germs and pests in the corresponding stages can be realized, and the disease incidence of walnut trees is reduced. Compared with a previous traditional post-treatment method that corresponding treatments are carried out after diseases or insect pests happen, the method has the advantages that pesticide expenditure cost is reduced, the fruiting rate of walnut trees is improved, and yield is increased.

Description

technical field [0001] The invention relates to the field of walnut cultivation and planting, in particular to a method for preventing and controlling walnut pests and diseases. Background technique [0002] Walnut, also known as walnut and Qiang peach, is the most widely cultivated at home and abroad. Deciduous trees, generally 10 to 20 meters high, up to 30 meters tall, with a trunk diameter of about 1 meter, and a life span of one to two hundred years, up to more than 500 years. The crown is large and open, in the shape of a semicircle or a round head, with a diameter of 6 to 9 meters. Bark grayish white to dark brown, young trees with smooth bark, old trees with irregular shallow longitudinal fissures. The branches are thick and smooth, and the shoots are green when they are first born, and can also be slightly red in early spring, and turn bright gray or taupe after they stop growing, with white lenticels. The pith of annual branches is larger and the xylem is soft, ...
