Technical Field

The invention relates to a method for controlling weeds, in particular to a method for controlling weeds in a tea garden.

Background

The weed harm is one of the main ecological problems faced by subtropical tea garden production, particularly in young tea gardens, the weeds are various in variety and difficult to control chemically, the weeds not only compete for water and fertilizer, light and space with tea trees and have adverse effects on soil structures, but also provide shelters for breeding of diseases and insect pests, become infection sources of the diseases and insect pests of the tea trees, influence the survival rate and growth and development of tea seedlings, and weed removal is required for 3-6 times every year in the young tea gardens for effectively controlling growth of the weeds, so that the planting cost is directly increased. The application of the chemical herbicide plays an important role in controlling weeds in tea gardens and improving production efficiency, but the harm of the chemical herbicide to human bodies and ecological environment is gradually shown. At present, the related standard stipulates that the tea garden needs to forbid the use of chemical herbicide, and the residue of the herbicide in the tea is also included in the index range of the safety limit of the tea quality. The method is provided for solving the substitute of the environment-friendly, economical and practical tea garden weed green ecological control technology which meets the requirements of high-quality, safe and efficient production of tea.

Disclosure of Invention

The invention aims to solve at least one technical problem in the prior art and provides a method for controlling the grass injury of a tea garden.

The technical solution of the invention is as follows:

a tea garden weed control method comprises the following steps:

the method comprises the following steps: pre-treating the tea garden ground surface;

step two: carrying out inter-planting on the mouse couch grass after the treatment of the first step.

Preferably, step two is followed by step three: care for the citionella.

Preferably, in the third step, the career of the lemongrass is specifically: and (4) after the cymbopogon citratus intercropping, performing topdressing for 1 time in combination with topdressing in a tea garden for 2-3 months.

Preferably, in the third step, the additional fertilizer dosage is increased by 100-200 kg/hm on the basis of the additional fertilizer dosage in the tea garden²

Preferably, in the first step, the tea garden surface covering pretreatment specifically comprises: and in 1 st year, continuously adopting a covering material to carry out closed type ground surface covering between rows of the tea garden in 4-9 months.

Preferably, in the second step, the intercropping common fescue is specifically: lifting the covering, removing weeds, deep ploughing, applying base fertilizer, leveling the ground and sowing the lemongrass seeds.

Preferably, the covering is made of a material which has low light transmittance or high density and is not easily degraded.

Preferably, in the second step, the time for intercropping the cogongrass is 10-11 months of the 1 st year of grass control.
