Abstract

The invention provides a method for controlling weeds in a tea plantation. In the method, bare surface soil between tea rows and on the altar in tea plantations is covered by straw or weed preventing cloth after weeding in spring and summer or after plowing and fertilizing in winter. The weed preventing cloth is made of cloth-like material which is woven by adhering non-woven fabrics to propene polymer (PP) filaments. Weeds in tea plantations are prevented and controlled by a physical method, the growth of weeds can be suppressed obviously, chemical herbicide is reduced or even avoided, and artificial and mechanical weeding cost is reduced. Adverse influence of weeds on the growth of tea trees is reduced, soil fertility in tea plantations is improved, water and soil are maintained, and ecology in tea plantations is improved. The method is easy to operate and can be easily accepted by tea growers and has an excellent popularization and application prospect.

Description

A kind of tea place control method for weed

Technical field

The present invention relates to a kind of tea place control method for weed, particularly a kind of holostrome covers tea place control method for weed.

Background technology

The weed in tea garden kind is many, and tea place, tropical and subtropical zone area had the weeds occurrence in peak period in 1 year 2 times, especially part fast growth, malignant weed and tea tree that the plant high-biomass is big strive water, strive fertilizer, strive the space, the photograph that wins honour for, influence growth of tea plant.At present to weed in tea garden general adopt artificial, power shovel except or use chemical herbicide to go out and remove, these methods cause degradation ecological environment problem under soil erosion, environmental pollution and the bio-diversity easily.

If can control the growth of weeds, the growth of weeds can not only improve the tea garden soil content of organic matter under controllable condition, improves soil texture, and can play the effect that conserves water and soil.

Summary of the invention

The method that the present invention adopts holostrome to cover reduces weeds photosynthesis by reducing illumination, suppresses weed growth speed, by the limiting growth space, and the control weed growth.

The technical solution used in the present invention is:

The method of a kind of tea place control weeds, described method is: after spring and summer extirpates weeds season or after ploughing fertilising winter, cover tea place tea exposed table soil in the ranks with stalk or anti-grass cloth, described anti-grass cloth is the cloth shape material that the bonding PP silk braiding of nonwoven forms.

Described tea place extirpate weeds be with herbicide go out cut weeds or manually, power shovel cuts weeds, and smooth table soil.

Further, in the described tea place, preferably cover the surface exposure soil of tea place terraced fields tread with stalk; Preferably cover the surface exposure soil of tea place terraced fields ladder wall with anti-grass cloth.

When covering the surface exposure soil of tea place terraced fields tread with stalk, described stalk is straw, straw or cogongrass.The consumption of described stalk is every mu of tea place 1000 ~ 1500kg.

Described stalk edge covers perpendicular to tea place contour direction, and cladding thickness is 15-20cm after suitably treading.

Concrete, when covering the surface exposure soil of tea place terraced fields ladder wall with anti-careless cloth, described anti-careless cloth is the cloth shape material that bonding black of nonwoven or the braiding of green PP silk form, and its light transmittance is less than 5%, and close proximity to ground during use is in the 10 ~ 20cm that places into the soil.Available dust compacting prevents from being raised by wind on the anti-grass cloth.When terraced wall width during greater than 1m, use bamboo cane etc. and it is fixed along the contour direction in terraced wall central authorities.

When described tea place was children tea place in age, described being covered as covered all bare lands of surface, tea place.Described tea place is for becoming age during the tea place, and the capable tree crown drip of tea 5cm need not cover with interior.

The tea place, south is distributed in hilly and mountainous land more, tea place ladder wall is comparatively precipitous, and the tread drop is bigger, and terraced wall can use the covering of weeding cloth to carry out weeds control, anti-grass cloth is a kind of cloth shape material that the bonding black of nonwoven or the braiding of green PP flat filament form, and the anti-grass cloth light transmittance is less than 5%.Lacking tea place, stalk area tread also can adopt anti-grass cloth to cover.

The tea place tread before covering earlier with herbicide kill, power shovel except or cut off clean weeds, should grub out for the weeds of stiff in straw and remove, and suitably flatten soil.The tea place tread covers stalk after smooth perpendicular to tea place contour direction, and suitably treads, and cladding thickness need reach 15-20cm.Children tea place in age should guarantee that tread table soil exposed part covers fully, becomes the capable drip 5cm of tea place tea in age can cover with interior.

Also answering weeding and smooth soil before ladder wall anti-grass cloth covers, make anti-grass cloth be close to the mud face as far as possible, need place into the soil in the 10-20cm in the anti-grass cloth edge.Available dust compacting on the anti-grass cloth, the growing space of the intractable weeds of a small amount of growth of restriction, and prevent from blowing anti-grass cloth is raised.Ladder wall width is used bamboo cane etc. greater than the anti-grass cloth of 1m and is fixed along the contour direction in terraced wall central authorities.

This method adopts physical method that weed in tea garden is carried out prevention and control, can obviously suppress the growth of weeds, reduces and does not even use chemical herbicide, reduces artificial and weeding by machine's cost.Both can reduce weeds to the harmful effect of growth of tea plant, and can improve again Tea Garden Soil Fertility, conserve water and soil, improve tea place ecology, and simple to operate, accepted by the tea grower easily, fabulous popularizing application prospect is arranged.

Embodiment

The present invention will be further described with specific embodiment below, but protection scope of the present invention is not limited thereto.

Embodiment 1

Use this method in 4 years age of tree years of a slice Iron Guanyin tea place, Youxi Ban Mian township winter in 2009 and control grass.This tea place is positioned on the low mountain of about 550 meters of height above sea level, is located in the middle subtropical zone monsoon climatic region, and soil is red soil.In early December, 2009, comprehensively clear weeding is carried out in the tea place, and carries out the fertilising in winter.The clear suitable smooth table soil in fertilising back of ploughing then is covered in tea tree both sides tread by every mu of 1000kg dry rice straw, because tea tree is less, tread is carried out all and covered.Straw is suitably treaded the about 15cm of thickness after covering.The terraced wall height of adjacent two terraced interlayers is mostly between 70-110cm.At first the anti-grass cloth with the 320cm wide cut half-and-half is cut into the 160cm wide cut, is covered in tea place ladder wall.Then top edge is imbedded 20cm in the tread ridge of upper strata, suitable steady and sure ridge, the fastness of anti-grass cloth is imbedded in assurance.Then suitably strain anti-grass cloth, it is dark that lower limb is imbedded the capable inboard row of the tea about 20cm in ditch.Grow bamboo cane with the anti-grass cloth compression and be fixed in terraced wall with a 300cm at the terraced wall every interval 300cm of central authorities along the contour direction at last.It is intact that in this year terraced wall covering reservation is implemented in this tea place, has no weeds and expose anti-grass cloth.The capable straw of tread tea cover part the Spring Festival in April to May the weeds peak period do not see obvious weeds.July-autumn in August is during the weeds peak, because straw rots and the impact such as manual work disturbance, part table soil lacks and covers, visible a small amount of weed growth, but weeds quantity and growing way are starkly lower than and do not cover the tea place.Nearly 1 year result of the test shows, uses holostrome and covers the tea place and control careless technology, can effectively control the weed growth of tea place ladder wall and tread, and the tread weeding can reduce 2-3 time the whole year, and terraced wall can be realized the not weeding whole year.
