Description

Multifunctional weeding machine for tea garden

Technical Field

The utility model relates to an agricultural machine utensil field, concretely relates to tea garden uses multi-functional weeder.

Background

The tea garden is mostly built in hilly areas of mountains, the planting mode of tea trees is mainly a hole-spacing strip planting mode, and wider tea row gaps provide excellent growth environments for weeds. If the weeds are allowed to grow in the tea garden at will without adopting corresponding control measures, the weeds compete for nutrients, sunlight and growth space with tea trees in the past, the growth of the tea trees is seriously affected, and the yield of the tea trees is reduced and the quality of the tea trees is reduced.

According to different influences of different types of weeds on the ecological environment of the tea garden, the weeds growing in the tea garden can be divided into beneficial weeds and malignant weeds. The malignant weeds comprise grass plants which have serious illumination, high growth and reproduction speed and difficult control and have relatively large negative effects on the growth of tea trees and compete for water and fertilizer with the tea trees in the tea garden; the opposite beneficial weed is a non-malignant weed. According to the incomplete statistics of the inventor, the malignant weeds in the tea garden comprise large crabgrass, cleavers, small centipeda herb, annual fleabane herb and the like, and the beneficial weeds comprise tremella aurantialba, large crabgrass, Japanese tetrapanax, incarvillea delavayi, humifuse euphorbia herb, cudweed herb, speedwell, astragalus sinicus and the like. The beneficial weeds have certain positive effects on the ecological environment of the tea garden, not only can improve the soil structure of the tea garden, prevent water and soil loss of the tea garden and the like, but also can provide foodstuff for insects in the tea garden to reduce the damage of the insects to tea trees. Therefore, the weed control of the tea garden should not only completely remove the weeds in the tea garden, but also remove the malignant weeds on the premise of reasonably reserving the beneficial weeds, sow the beneficial weeds in the tea garden, and reasonably control the weeds and the ecological environment in the tea garden in a grass-control mode.

The weeding in the prior art mainly comprises three modes of chemistry, biology and physics, wherein the physical method can be divided into artificial weeding, mechanical weeding and the like. The mechanical weeding method is widely applied due to low cost, higher weeding efficiency and no potential biochemical harm to the ecological environment of the tea garden. In the prior art, a tea garden weeding device disclosed in utility model patent with publication number CN 212367855U can only cut off the stem leaves of weeds, and can not effectively remove the rootstalks of weeds growing below the ground, so that the rate of regrowth of weeds is higher, and the weeding efficiency of a weeding machine is reduced. In addition, the prior art does not disclose a device which can realize weeding and grass planting in a tea garden at the same time.
