Problems solved by technology

On the one hand, because the larvae of this kind of pests are mostly in the branches or bases, it is difficult to find them. When symptoms such as dryness appear, most of the larvae have already penetrated into the xylem, so it is difficult to control; decline, and seriously affect the yield and quality of Camellia oleifera

Embodiment 1

[0019] A kind of method for preventing the camellia oleifera chrysanthemum borer, the operation steps are as follows:

[0020] 1. Understand the occurrence rules of pests

[0021] Before taking effective preventive measures, first understand the occurrence characteristics and damage rules of this kind of dry borer, and know the egg stage, larval stage, pupa stage and overwintering stage of this kind of dry borer. Since the larvae or adults of this type of pest live through the winter in the main root of the host or in the damaged branches, it is generally necessary to choose to take corresponding preventive measures before the end of the wintering period. The prevention cycle can be determined according to the characteristics of occurrence and the law of damage, and the best prevention period can be grasped for prevention and control.

[0022] 2. Special fertilizer configuration

[0023] A specific fertilizer made of nicotine compound ingredients composed of nicotine or nico...

Embodiment 2

[0030] A method for preventing the stem borer of the camellia oleifera forest. In 2016, a control test was carried out on the camellia oleifera forest in Mayuantun, Gaoji Township, Sanjiang County. The specific operation is: the Camellia oleifera stand is 3 years old, the planting variety is the Cenruan series of Camellia oleifera clones, the row spacing between plants is 2m*3m, and the planting area is 5 mu. First of all, by setting up regular surveys of sample plots to understand the occurrence rules and damage levels of insect pests, it was found that 9% of the Camellia oleifera in the forest land suffered from the damage of stem borers, resulting in cortical ring cracks, tree nutrient and water transportation was blocked, and individual serious trees Body depletion occurs. According to the hazards of the woodland, choose to apply 1 catties of compound fertilizer and 4 catties of nicotine mixed top dressing (N=15%, P 2 o 5 =7%, K 2 O=8%, the organic matter content reache...

Embodiment 3

[0032]A method for preventing the stem borer of the Camellia oleifera forest. In 2015, a control test was carried out on the Camellia oleifera forest in Chankoutun, Liangkou Township, Sanjiang County. The specific operation is: the Camellia oleifera forest in this forest land is 10 years old, the spacing between plants and rows is 2m*3m, and the area is 10 mu. Firstly, through the on-the-spot investigation of the base, the occurrence regularity and basic damage degree of the pests were mastered. After the investigation, it was found that 15% of the camellia oleifera in the forest land were damaged by the stem borer, and there was a pile of light yellow sawdust-like insects at the root of the tree. Dung sawdust, and some serious trees have obvious bores. According to the hazards of the woodland, choose to apply 2 catties of compound fertilizer in combination with the soil fertility status, forest age, and tree size of the woodland before the spring shoots germinate in December ...

Abstract

The invention discloses a method for preventing longicorn stem borers of a camellia oleifera abel forest. The method comprises the following steps: carrying out prevention in an egg stage, a larval phase and a pupal stage of larvae or adults wintering in host plant roots and stems or in suffered trunks, and during the time from December to January of next year when fertilizers are applied to the wintering period; adding nicotine or an organic compound fertilizer accommodating nicotine complexing agent components into a base fertilizer or an additional fertilizer of camellia oleifera abel; directly applying the base fertilizer into a planting hole; directly applying the additional fertilizer to the periphery of a tree body in a manner of spreading, and digging up soils to cover the fertilizer. The method is simple, goal-oriented, strong in operability, environment-friendly, effective and practical, can effectively and directly carry out prevention in the occurrence period of the longicorn stem borers, prevents the stem borers from damaging the trunks and the stems of the camellia oleifera abel forest, reduces the risk of insect damage occurrence to a certain degree, effectively restrains the risks of yield declining and quality deterioration caused by insect damage, guarantees the health, yield and quality of the camellia oleifera abel forest and has good economic benefits, social benefits and ecological benefits.

Description

technical field [0001] The invention relates to a method for preventing stem borers of Camellia oleifera, specifically a method of adding fertilizers containing nicotine components to base fertilizer or topdressing fertilizer according to the occurrence rules of pests to prevent the harm of stem borers, which belongs to forest diseases and insect pests The technical field of prevention and control. Background technique [0002] Camellia ( Camellia oleifera Abel.) is a unique woody edible oil tree species in my country, and it is also the main traditional characteristic economic forest in Guangxi. In recent years, under the policy support of the state and the autonomous region, especially the promulgation and implementation of "National Camellia Camellia Industry Development Plan (2009-2020)" and "Camellia Camellia Industry Development Plan of Guangxi Zhuang Autonomous Region (2010-2020)", the growth of Camellia oleifera industry The pace of development continues to acceler...
