Problems solved by technology

The parasitism of Platanus biscuits will lead to poor growth and weakened growth of the host, and the parasitized branches are easy to die and wither. These fallen branches may cause harm to pedestrians and vehicles on the road
Because Platanus biscuits is often used as a street tree and is widely cultivated in cities in Southwest my country, and the parasitism of trichomes is widely distributed in the subtropical regions of Southwest China, however, there is no report on the effective control of this common parasitic hazard phenomenon.

Embodiment 1

[0024] Embodiment 1: a kind of method of controlling the parasitism of hairy leaves to the damage of Platanus bilobosa, it may further comprise the steps:

[0025] S1. Parasitic hazard investigation: count the number of individuals parasitic on a single sycamore tree; each parasitic clump is recorded as a parasitic plant; use a telescope to check the number of single syringa The number of individuals parasitizing Amblycarpa trichomes on sycamore trees;

[0026] S2. Classification of parasitic intensity: according to the number of individuals who are counted in the step S1 to be parasitic, the parasitic intensity level is divided into severe parasitism, moderate parasitism, mild parasitism and zero parasitism, wherein, the Severe parasitism refers to the number of parasitic individuals ≥ 30 on a single host tree, more than 50% of the crown is replaced by parasitic clumps, and the host branches are dead; the above-mentioned moderate parasitism is 30 > the number of parasitic ind...

Embodiment 2

[0032] Embodiment 2: a kind of method of controlling the parasitism of trichomes to the harm of Platanus bilobosa, it may further comprise the steps:

[0033] S1. Parasitic hazard investigation: count the number of individuals parasitic on a single sycamore tree; each parasitic clump is recorded as a parasitic plant; use a telescope to check the number of single syringa The number of individuals parasitizing Amblycarpa trichomes on sycamore trees;

[0034] S2. Classification of parasitic intensity: according to the number of individuals who are counted in the step S1 to be parasitic, the parasitic intensity level is divided into severe parasitism, moderate parasitism, mild parasitism and zero parasitism, wherein, the Severe parasitism refers to the number of parasitic individuals ≥ 30 on a single host tree, more than 50% of the crown is replaced by parasitic clumps, and the host branches are dead; the above-mentioned moderate parasitism is 30 > the number of parasitic individu...

Embodiment 3

[0040] Embodiment 3: a kind of method of controlling the parasitism of trichomes to the harm of Platanus bilobosa, it may further comprise the steps:

[0041] S1. Parasitic hazard investigation: count the number of individuals parasitic on a single sycamore tree; each parasitic clump is recorded as a parasitic plant; use a telescope to check the number of single syringa The number of individuals parasitizing Amblycarpa trichomes on sycamore trees;

[0042] S2. Classification of parasitic intensity: according to the number of individuals who are counted in the step S1 to be parasitic, the parasitic intensity level is divided into severe parasitism, moderate parasitism, mild parasitism and zero parasitism, wherein, the Severe parasitism refers to the number of parasitic individuals ≥ 30 on a single host tree, more than 50% of the crown is replaced by parasitic clumps, and the host branches are dead; the above-mentioned moderate parasitism is 30 > the number of parasitic individu...

Abstract

The invention discloses a method for controlling the damage to Platanus biscuits caused by the parasitic fruit leaf parasitism, which includes parasitic damage investigation, parasitic intensity grading and grading damage treatment. The present invention proposes a treatment method for parasitism of blunt fruit with hairy leaves and damage caused by sycamore syringae with different parasitic intensities through the division of sycamores with different parasitic intensities. The invention overcomes the disadvantages of rapid and difficult-to-control parasitism of the blunt fruit of hairy leaves, significantly controls its spread and harm, fills in the blank of its harm control method, and has reference value for the control of parasitic harm to other tree species. The method provided by the invention has the advantages of simple operation, remarkable treatment effect and low treatment cost, and can be applied to the treatment of the damage caused by the parasitism of the hairy leaves to the sycamore sycamore in cities.

Description

technical field [0001] The invention relates to a method for controlling the damage caused by semi-parasitic plants to urban garden trees, in particular to a method for controlling the damage caused by the parasitism of hairy leaves to sycamores. Background technique [0002] Two ball plane tree ( Platanus acerifolia ) is a common urban greening tree species, excellent shade tree and street tree. It grows rapidly, has a beautiful plant shape, and has strong adaptability. [0003] Phyllostachys pubescens ( Taxillus nigrans ) is the genus Ammonia ( Taxillus ) is an evergreen semi-parasitic plant, which is widely parasitic on Platanus bilobosa, Ginkgo biloba ( Ginkgo biloba ), tree structure ( Broussonetia papyrifera ), Metasequoia ( Metasequoia glyptostroboides ),locust( Robinia pseudoacacia ), Magnolia ( Magnolia denudate ), Purple Leaf Plum ( Prunus cerasifera ),weeping willow( Salix babylonica ), wrinkled papaya ( Chaenomeles speciose ), Silverwood ( ...
