Control method of weed in tea garden

Abstract

The invention discloses a method for controlling weeds in a tea garden, which comprises the following steps: first, plowing is carried out on the ground between tea plant rows in winter to remove root systems of the weeds such as nutgrass flatsedge, alligator alternanthera, greenbrier, chinaroot greenbrier, cogongrass, smartweed, lygodium and the like; a high-quality organic fertilizer is applied in spring: a certain amount of rape seed cake fertilizer is broadcast; the ground is covered with rice straws in spring: after the rape seed cake fertilizer is broadcast, all tea plant rows in the garden are immediately evenly covered with a certain amount of the rice straws; the high-quality organic fertilizer is applied in summer: a proper amount of the rape seed cake fertilizer is broadcast at a certain time; and the ground is covered with the rice straws in summer: after the rape seed cake fertilizer is broadcast, all tea plant rows are immediately evenly covered with a certain amount of the rice straws. The method enriches biodiversity of the tea garden, improves the ecological condition of the tea garden, increases tea yield, improves the quality of tea leaves; in addition, the method has the advantage of simple operation, is easy to be accepted by tea growers and has great popularization and application prospect.

Description

technical field [0001] The invention relates to the field of tea tree cultivation, and more specifically relates to a method for controlling weeds in tea gardens, which is especially suitable for subtropical hilly tea areas. Background technique [0002] As the components of plant diversity in the tea garden ecosystem, weeds can effectively change the structure of the tea garden ecosystem and directly affect the biodiversity and quantity allocation of the tea garden. At the same time, weeds compete with tea trees for water, fertilizer, space, and sunlight. They are also breeding shelters for pests and pathogenic microorganisms, seriously affecting the yield and quality of tea, and causing great harm to tea production. There are many kinds of weeds in tea gardens, which grow vigorously and are difficult to control, which seriously affects the normal growth of tea trees. [0003] There are many kinds of weeds in tea gardens, including 1-2 years old and perennial early spring ...

[0005] Manual weeding in tea gardens consumes a lot of labor, the duration of no weed damage is short (only 10-20 days), and the benefit of weed control is low

Several herbicides such as Caoganning and Gramoxone are commonly used for chemical weeding in tea gardens. Tea trees are highly resistant to these herbicides. The use of herbicides in tea gardens pollutes tea leaves, resulting in excessive pesticide residues in tea leaves; herbicide residues in the soil will also destroy the community structure of microorganisms, soil insects and other small animals in the soil, and destroy the rhizosphere organisms in the tea garden soil normal structure of diversity
