Description
Technical field
The present invention relates to environmental protection, bionomic control technical field is wide more particularly, to a kind of interplanting pulse family Chinese herbal medicine
The method of herba lysimachiae prevention and treatment young tea plantations soil erosion and prevention and control weeds.
Background technique
Tea tree is that Theaceae, Camellia shrub or dungarunga, spray are hairless.Leaf keratin, oblong or ellipse.Tea tree
Leaf can tea making, seed can extract oil, and tea tree material is fine and closely woven, and wood can be used for carving.Southwestern China portion is in the origin of tea tree
The heart has 60 countries to introduce a fine variety tea tree in the world.Also there is arbor type tea tree to be up to 15~30 meters in torrid areas, base portion tree encloses
1.5 meters or more, the age of tree is up to centuries to more than one thousand years.Its growing environment orographic condition mainly has height above sea level, hillside fields, slope aspect etc., pole
It is few to be planted on Plain.In the mountain area or knob of certain altitude, abundant rainfall, cloud and mist is more, and air humidity is big, diffusion
Light intensity, this is advantageous to Growth of Tea Plants, is typically chosen slope by north preferably.
For newly opening up wasteland tea place, there are mainly two types of band mode is opened, digging machine opens band and manually opens band.Digging machine opens band because having
It is high-efficient, the time is saved, the advantage of cost is saved, becomes most common and opens band mode.But digging machine opens band, there is also all
More drawbacks: (1) scooping away the fertile topsoil soil in surface layer, bottom it is uncooked it is barren, fertility is low, hardened soil become last tea shoot kind
The soil layer of plant causes tea tree seedling stage undergrowth；(2) since the Teaching practice base that furthermore topsoil is rich in also can be with topsoil soil quilt
It removes, causes the original Teaching practice base missing of soil, revegetation is difficult, easily causes soil erosion；(3) periphery new raised weed
Invasion growth influences tea shoot growth, increases weeding cost.
The growth of weed in tea garden causes great harm the growth of tea tree, especially young tea plantations, due to spatial surface
It is larger, it is easier to breed weeds.Weed infestation growth of tea plant is mainly manifested in and tea tree contention fertilizer, moisture and sunlight.Tree it is high compared with
Low tea tree tends to be covered fluffy face by weeds, such as not in time removes weeds, will cause tea tree death.
The Chang Fangfa of control of weeds is mainly artificial weeding, weeding by machine, covering weeding and chemical herbicide weeding.It is mechanical
Weeding is limited vulnerable to landform, poor operability；Larger workload needed for covering weeding, subsequent rotten stalk easily become pest and disease damage
Vector；The artificial weeding amount of labour is big, cost is up to 600~800 yuan of mu/years, counts according to 20-30 jins of tealeaves per mu yield,
Tealeaves weeding cost of labor per jin then needs 20~40 yuan, and tea place production management recruitment at present is extremely short, and the production busy season asks
Work is more difficult；Although chemical herbicide weeding weeding ratio is high, at low cost, a large amount of uses will cause tealeaves pollution and ring
Border pollution, does not meet the modern agricultural development target of environmental-friendly-green high-efficient.Therefore, most enterprises are raw for Famous High-quality Tea
It produces, still selects artificial weeding mode to carry out weeding, but this brings huge financial burden to enterprise.
Meanwhile the tea place terraced fields side slope surface newly opened up wasteland is since soil is soft, mass erosion, rain drop erosion, the slope surface gradient
The factors such as big easily cause slope surface soil erosion, can lead to large area slope dilapidation when serious, terraced fields damage.Tea place is opened up wasteland to new
It influences very big.If not focusing on the management for newly opening up wasteland young tea plantations, soil erosion is easily caused, it is not only very big to environmental hazard,
The sustainable development in tea place and the yield and quality of tealeaves are also affected simultaneously.
Therefore, lacking at present a kind of easy-to-use can promote revegetation to reduce soil erosion and fertilizing soil
The tea place herbicidal methods newly opened up wasteland, this is serious to constrain the development of China's Tea planting industry.
