Embodiment Construction

[0026] Below in conjunction with specific embodiment the present invention is described in further detail:

[0027] Select the citrus orchards that have already suffered from the disease as the implementation point.

[0028] Spray pesticides on fruit trees, mainly to kill psyllids and other pests for disease and pest control, clean up and burn the surrounding dead fruit trees, including dead branches and fallen leaves, and then use lime powder to disinfect the surrounding areas and adjust the pH of the soil. Sprinkle with 50Kg of lime, mainly for the area within the drip line of the crown. After one month, check the pH of the soil. If the pH is 4.8, continue to use lime at an amount of 25Kg / mu again. After another month, the pH is 5.8. .

[0029] After the first lime, apply the biological fertilizer containing Bacillus to the fruit tree. The use of biological fertilizer should be used twice a year, one of which should be used within one month after picking the fruit, and the ...

Abstract

The invention discloses a greening disease prevention and control method. An organic water-soluble fertilizer containing chitin and rare earth, a leaf fertilizer containing chitin and rare earth elements, a biological fertilizer containing bacillus and a conventional greening disease prevention and control method are adopted for treatment. After fruit trees disease, tree bodies are not felled and can be treated, and loss is reduced. The fruit trees which do not disease can be subjected to prevention and control. The rare earth elements and the organic water-soluble fertilizer can improve the sweetness and other qualities of fruits. Soil can be improved.

Description

【Technical field】 [0001] The invention relates to a method for preventing and treating Huanglongbing, belonging to the technical field of agricultural planting. 【Background technique】 [0002] Citrus huanglongbing is also known as yellow shoot disease, yellow wilt and green fruit disease. The disease broke out in Guangdong in the 1970s, spread to southern Fujian and Fuzhou in the 1980s, and spread to northern Fujian in the 1990s. Huanglongbing was found successively in counties (cities) such as Yanping, Shunchang, and Jianou, causing serious damage to citrus. Great harm. [0003] Huanglongbing can be manifested in branches, leaves, flowers, fruits and roots, especially in autumn shoots. In the early stage of the disease, some of the leaves of new shoots turn yellow, and "yellow shoots" appear. The yellow shoots first appear on the top of the crown and then gradually expand. After 1-2 years, the whole plant becomes sick. After the base of the veins turns yellow, part of th...
