[0011] (1) Clearing the garden: Clearing the garden in winter from December to January every year, cutting off diseased and insect branches, dead branches, closed branches, cross branches and weak branches, and removing too many upright branches, especially sparse sawing (cutting) Go to the top of the canopy to block the sun (light) and make the big branch angle greater than 65 degrees; reduce the tree height so that the tree height is less than or equal to 0.6 of the row spacing, and improve the ventilation and light transmission conditions of the tree body. Remove weeds and fallen leaves in the orchard, eradicate the source of disease and burn them intensively. Simultaneously use 45% crystal lime sulfur mixture to make 150 times liquid medicine, evenly spray wet to whole tree, branch, leaf surface, leaf back, spray altogether 2 times. In terms of cultivation and management, rational application of phosphorus and potassium fertilizers can improve the disease resistance of tre...

Abstract

The invention discloses a method for realizing safe and efficient planting and fruit scab control on Shatian pomelo and belongs to the forestry disease control technology. The damage of pomelo scab becomes the first killer of the poor appearance quality of Shatian pomelo fruits; the fruits suffer from the problems of pollution and residues of toxic substances by pesticide abuse to seriously influence food safety, and therefore, the quality and the competitiveness of the fruits are seriously influenced. The method disclosed by the invention comprises the following steps: (1) clearing an orchard; (2) performing medical treatment; (3) bagging the fruits; (4) performing plastic film mulching. The method disclosed by the invention has the advantages that the disease rate of the fruits is reduced to 2.5-3 percent; a control effect is obvious; germ sources are reduced; the food safety is improved; ecological safety, high quality, high yield and high efficiency are achieved.

Description

technical field [0001] The invention belongs to the technical field of forestry disease prevention and control, and more specifically relates to a method for realizing the safe and efficient planting of Shatian pomelo to prevent and control fruit scab. Background technique [0002] In recent years, Shatian pomelo, a well-known and excellent fruit, has suffered from poor appearance and poor market competitiveness. In production and cultivation, fruit diseases and insect pests are becoming more and more serious, especially the damage of pomelo scab has become the number one killer of poor appearance quality of Shatian pomelo fruit. Pomelo scab (also known as black spot) is becoming more and more serious in Shatian pomelo production areas, and has become the most important disease affecting the appearance quality of Shatian pomelo fruit. According to the survey, the affected area in Rongxian County, Guangxi in 2009 reached 103,000 mu, and almost 100% of some orchards were affe...
