Embodiment 1

[0035]The prevention and control method of lemon gum gum disease that the embodiment of the present invention provides specifically comprises the following steps

[0036] 1. Choose a planting site with good environmental sanitation, and plant lemons away from residential areas and rural domestic sewage discharge areas. The distance between rows and plants on flat land and gentle slope is 3.5m×2.5m, and 76 plants are planted per mu. The row spacing of plants on slopes is 4.0m×3.0m, and 55 plants are planted per mu.

[0037] 2. When lemons are planted, increase the height of the lemon grafting interface, and the grafting interface is ≥ 15 cm from the ground, so as to avoid the soil covering the grafting interface caused by fertilization and other measures in lemon production.

[0038] 3. Apply base fertilizer to supplement mineral nutrition to prevent and control gum disease

[0039] From September to October every year, combined with the lemon orchard, apply fruit fertilizer,...

Abstract

The invention belongs to the technical field of bleeding disease control, and discloses a method for controlling a bleeding disease of lemon trees. The method includes: applying a fruit picking fertilizer to a lemon orchard during September-October every year, controlling the use amount of a nitrogenous fertilizer, adding a potassium fertilizer and a boric fertilizer, and suitably supplying a calcium fertilizer and a zinc fertilizer; performing winter whitewashing on the lemon planting orchard during October-December in autumn and winter every year, and importantly whitewashing trunks of lemon trees and bleeding disease parts of the trunks; checking the bleeding disease morbidity of the lemon trees during a peak stage of the bleeding disease in July-August in the next year, and whitewashing the trunks and the bleeding disease parts of the trunks again; spraying the lemon trees with a chemical fertilizer in a root outside manner so as to control the bleeding disease, controlling the use amount of a nitrogenous fertilizer, adding a potassium fertilizer, and suitably supplying a boric fertilizer; and suitably supplying a boric fertilizer while controlling the branch diseases of the lemon trees from a fruit expansion early stage to a fruit expansion middle stage of the lemon trees. The method can mainly control the bleeding disease, can lower the morbidity and the serious degree of the bleeding disease, and can increase the economic benefits of the lemon trees.

Description

technical field [0001] The invention belongs to the technical field of gummosis prevention and control, and in particular relates to a method for preventing and controlling lemon tree gummosis. Background technique [0002] Lemon is an evergreen fruit tree of the Rutaceae citrus genus. The fruit is rich in essential nutrients such as amino acids, vitamins, and various trace elements, and is an excellent fruit for human health. Lemon has a wide range of practical value, and the demand is increasing. Currently, lemon is a popular fruit in the international market and has great potential for commercialization. However, due to the damage of pests and diseases, lemon plants die, a large number of lemons drop flowers and fruits, which reduces the yield, and fruit surface disease and insect spots affect the appearance quality, thereby affecting the economic benefits of lemon growers. Gum flow is a disease that lemons are very susceptible to. It not only affects the growth and dev...
