Strong sex. The growth of weeds in tea garden is not only harmful to the growth of tea trees, but also harmful to the creatures in tea garden.
The virtuous circle of chain plays an important role. In this paper, the control measures of weeds in tea garden and the comprehensive utilization of raw grass were discussed
This paper expounds the weed control technology in tea garden from two aspects.
Discussion on weed control technology in tea garden of Mingxi county, there are many kinds of weeds, wide distribution area and fast growth and reproduction.
Most malignant weeds often compete with tea trees for glory and fertilizer, covering the crown of tea trees. If we control them,
If it is not timely, it will lead to "straw wrapped in tea", which will make the tea garden barren and have strict restrictions on the growth of tea trees.
Serious harm directly affects the yield and quality of tea. If the prevention and control measures are improper, not only
A large amount of flower work will also destroy the ecological environment of tea gardens, resulting in soil erosion and lodging of tea trees.
Outbreaks of pests and diseases. Practice has proved that only by taking comprehensive control measures such as agronomy and biology,
Only by combining weeding with cultivation, seeking advantages and avoiding disadvantages, and controlling weed growth in time can tea trees be guaranteed.
Normal growth, maintaining the ecological balance of tea garden. At present, the main types of weeds in tea gardens are
Common weeds are Gramineae, Compositae, Menispermaceae, Dianthus chinensis, Polygonaceae and Salix.
Herbs, Scrophulariaceae, Cruciferae, etc. According to the local tea production practice, this paper discusses the prevention and control measures.
Some opinions on weed control in tea garden.
1 Weed control measures in tea garden
Weed control in tea garden must be based on different ecological conditions, weed varieties and seasons.
Section, using manual, biological and mechanical methods, so as to achieve the combination of cleaning and maintenance,
Comprehensive measures such as replacing green manure with grass and protecting natural enemies were taken to control the growth of weeds in tea gardens. ask
Change the concept of "all around", hoe the grass when you see it, spray it when there is grass, and kill all the grass.
Species, serious damage to the ecological balance of tea garden behavior, strictly control the use of chemicals in addition to.
Grass, to prevent residue.
1. 1 main control methods
1. 1. 1 Dig out the roots of deep-rooted stubborn weeds when clearing the garden. Newly developed tea
Garden, before planting tea trees, or when reclaiming barren tea gardens, is particularly important for weeds in the garden.
It is deeply rooted, and the roots of vines and other malignant weeds, such as imperata, ferns, Stephania tetrandra and other plants, must be
Clean up in time.
1. 1.2 to prevent the spread of grass seeds. Fence manure, compost manure and livestock manure were applied in tea garden.
Farm manure, etc. Before application, it should be treated harmlessly, fully composted and decomposed, and reduced as much as possible.
Less weed seeds spread and multiply.
1. 1.3 Control the growth of weeds in time. Dig out the growth and entanglement in the crown of tea tree in time.
Weeds on tea trees; It grows on borders, stepped walls, ditches and roadsides.
Weeds must be pruned during the vigorous growth period and before flowering and fruiting.
1.2 main methods
1.2. 1 artificial weeding. One is to manually pull out (take root) around the stem of tea tree.
And weeds entangled in the crown of tea trees and tea bushes; The second is cutting with a knife or lawn mower.
In addition to growing in tea garden boundaries, ladder walls, roadsides, ditches and other open spaces to win glory with tea trees.
Weeds vying for fertilizer; Thirdly, dig out the white thatch on the crown and edge of the tea garden with a hoe.
Deep-rooted malignant weeds such as bracken, elephant grass, Stephania tetrandra and pueraria lobata; Fourth, the weeding period should be dominated by grass.
In the case of convenient growth and labor arrangement, choose the period when weeds are flourishing and flowering.
Before fruiting, before tea picking or after tea picking; Fifth, choose sunny and cloudy days; six
Except weeds, which should be used as drought-resistant mulch, the rest should be spread in the sun in time until the grass is gone.
After watering, turn it over and bury it under the drip line of tea tree crown for composting.
1.2.2 mechanical weeding. After picking spring tea, summer tea and autumn tea, the tea is mechanically cut off.
This garden is harmful to grass. You can choose CG4 15 produced by Zhejiang Yongkang Dingcheng Industry and Trade Co., Ltd..
Lawn mower, a series of lawn mowers produced by Jiangsu Changzhou Wuxing Plant Protection Machinery Co., Ltd.
However, weeds around the stem of tea tree, around the crown of tea tree and in the middle of tea tree should be used.
Pull it out manually to avoid cutting the tea branches and stems. It is planned to use newly-made tea and mechanically weed.
Garden, it is best to use the wide spacing planting method, that is, two plants are planted in a single row, one plant in a row.
The tea garden with the distance controlled within 50× 150- 180 cm is more convenient for mechanized operation.
1.2.3 biological control: in the grass growing period of tea garden, raise appropriate herbivores to control weeds.
Grass grows. The purpose of keeping animals in tea garden is to control the overgrowth of weeds.
There should not be too many animals, otherwise it will easily cause soil hardening in tea garden, which is not conducive to the growth of tea trees.
The specific stocking amount depends on the size of the animals and the amount of grass in the tea garden. such as
Tea garden 10-20 chickens/667m2 or 3-5 geese/667m2 can also be raised.
Sheep1-2/667m2.
2 Comprehensive utilization of raw grass in tea garden
2. 1 Tea garden grass is a natural high-quality green manure and drought-resistant plastic film. "You get fat when you see green,
The agricultural proverb "Rot leads to obesity" is used by working people to explain that weeds are green.
There are many kinds of fertilizers with good fertilizer efficiency. Weeds in tea gardens grow naturally and have strong resistance.
The formed natural community is lush, with many leaves and tender stems and branches, which can be directly cut down for many times.
The cost is extremely low, and it is not easy to bring in pests such as diseases, pests and weeds from other places. Zai Chun
Weeds abandoned in tea garden after tea, after summer tea and when clearing the garden in winter are the drought prevention measures of tea garden.
Low-cost, high-quality organic covering with temperature regulation; Plant shapes growing on borders and stepped walls
Creeping grasses such as dwarf tender grass and barnyard grass are ideal living covers for tea gardens.
Things.
2.2 Rational planting of grass to protect natural enemies of tea pests. There are many kinds of weeds in the tea garden, such as:
Grass seeds with long flowering period, such as Japanese cyanine, are very beneficial to the reproduction and activities of parasitic bees and cattle.
Grass species with soft stems and leaves, such as Toona sinensis and Poa pratensis, are beneficial for birds to nest and breed.
2.3 Transfer the host grass of tea pests. The feeding habits of tea pests are quite miscellaneous, which depends on the actual situation.
Generally speaking, most weeds in tea gardens are more vulnerable to pests than young tea leaves.
The weight of the tree. Insects such as tea leafhopper, tea geometrid, tea caterpillar and leaf roller moth are all tea and grass.
Pests that eat (suck) at the same time. Therefore, it is necessary to cut the green in time to keep the weeds young for a long time.
Pests on tea trees can spread to the grassland, and can be directly used artificially on the grassland when they occur in large quantities.
Capture, if the epidemic breaks out, you can directly control the grassland with chemicals, which can reduce
The harm degree of pests to tea trees, and avoid using pesticides on tea trees.
