Description

The tea place tea tree is planted clover in the ranks and cuts weeds and hold fertile method

Technical field

The present invention relates to a kind of biological nature of utilizing, effectively remove the method for weed in tea garden.

Background technology

In tea place, the plantation tea tree needs fertilising, with the growing nutrient that guarantees tea tree, needs.Due to the fertilizer abundance, tea tree in the ranks, the growth of malignant weed (harmful grass) is also quite rapid, the production of weeds height can reach more than 1 meter, and the height of tea tree is only less than 1 meter, so, if let alone the weeds free growth, can cover with whole tea place, make tea tree can not obtain sunlight, thus serious impact the operation such as the growth of tea tree and management, harvesting.

The tea place of especially newly opening up, the harm that young tea tree is subject to more very.

In order to guarantee tea tree, the normal growth of especially young tea tree, present stage is all the method that adopts chemical weeding or artificial weeding.

Artificial weeding, because the weeding cycle is short, generally in the plant growth busy season, the two weeks left and right is except weeds.So that workload is large, and human cost is too high.Today in short supply in recruitment, contradiction is still for outstanding.

And chemical weeding, because the kind of weeds is many, the stability of effect can not guarantee.The steriland herbicide of wide spectrum is large to the side effect of crop and soil, and more serious consequence is: the chemical residual of weed killer herbicide forms harm to tea tree, and serious impact the quality of tealeaves, soil is caused to irreversible pollution simultaneously.

For these reasons, a kind of method that we are devoted to find more efficient, safety always and cut weeds cheaply, through the trial of various means, determined the research direction of utilizing biological method: plant applicable plant.At first, this Plants can not have influence on the growth (concrete requirement is exactly that plant height can not surpass tea tree) of tea tree; Secondly, plant can fight for limited production space with injurious weed, thereby suppresses the growth of injurious weed; Again, plant is also wanted to provide nutrient for growth of tea plant; Finally, can't be too high for planting cost.

Above-mentioned just our subjective requirement, natural world not necessarily just exists so suitable plant species.But the repetition test through us, also found satisfactory plant: clover really.

Clover has another name called trefoil, herbaceos perennial, and clover is high-quality legume forage, the cauline leaf jewelry, expensive clothing and other valuables, the leaf amount is abundant, and crude protein content is high, and crude fiber content is low, and plant is short, high 30～40 centimetres.Taproot, root has the characteristic with the rhizobium symbiosis, and root tillering ability and regeneration capacity are all strong.

Summary of the invention

The purpose of this invention is to provide a kind of tea place tea tree plants clover in the ranks and cuts weeds and hold fertile method to make up the deficiency of prior art.

The technical solution used in the present invention is: the tea place tea tree is planted clover in the ranks and cuts weeds and hold fertile method: the tea tree in tea place is planted clover in the ranks;

Field is the terrace land tea place, gentle slope that level land or the gradient are less than 15 degree, and tread width should be not less than 1.8-2.0m, is conducive to like this terraced wall and terraced bank outer sowing clover; The operation tea place more than 3 years should be selected to plant in tea place;

The live mode of seed is taked in plantation; Every mu of sowing seed 0.4-0.6kg;

Sow trefoil First Year, because clover is also more immature, need human assistance to weed out the rank grass and be beneficial to the strong growth of trefoil Zhu; After Second Year, reach the clover density of terraced wall in the ranks oneself is larger in tea place, and hexyl has not originally had the growing space of other weeds; Just can reach the purpose careless with grass system fully by this;

When clover reaches the height of 30cm, just to mow, the grass of cutting off is placed in tea root pocket soil table in tea place.

Optimize: the seed sowing time be chosen in early spring (20-March 20 February) and plum rain season arrive in (June) be the best.

Beneficial effect of the present invention and principle thereof are: 1. in tea place, in the ranks plant clover (particularly in mountain area and the terraced wall in terrace land tea place, gentle slope, hills and in the ranks the plantation), can significantly improve soil, tea place afforestation coverage rate.Not only can play the effect that conserves water and soil and prevent erosion, can also effectively improve that tea place is cold-resistant, the ability of drought resisting.

2. due to clover plant shorter (general height about 30cm), and the paulin panel height degree in production tea place is generally more than 80cm.So its unlikely normal growth that affects tea tree because fighting for sunlight.

3. clover is greening greenbelt plants commonly used, belongs to the perennial herb crop, can once sow long-term being benefited.By plant clover in the ranks in tea place, just as planted a slice lawn in the ranks in tea place, effectively seized the growing space of other weeds, the growth of other malignant weed in the restriction tea place, thus play stop that tea place exceeds standard because the agriculture of using chemical herbicide and bringing is residual and soil fertility under the degradation negative effect.

4. clover has the characteristic with the symbiosis of root pomegranate bacterium as pulse family draft crop, with other legume, relatively has evergreen advantage of the four seasons.We are exactly the respiration of utilizing legume, and the airborne nitrogen essence of a large amount of absorptions is nourished and grown to supply tea tree in soil throughout the year, effectively improves the fertility of tea garden soil; Larger and anti-the cradling of Growth of Red Clover amount.We at least can mow in 1 year three times, and cut grass is covered under the tea root pocket, have just become the natural organic fertilizer of high-quality after the cauline leaf of clover softness rots, and can save the enormous expenditure that bring because using commercial fertilizer in tea place.

Fig. 1 is schematic diagram of the present invention.

Embodiment

Embodiment:

Field should be chosen in the terrace land tea place, gentle slope that level land or the gradient are less than 15 degree, and tread width should be not less than 1.8m, just is conducive to terraced wall and terraced bank outer sowing clover.The production tea place more than 3 years should be selected to plant in tea place.

Trefoil kind can select to spend in vain three leaves and two kinds of safflower three leaf all can.

Trefoil sowing: generally adopt the live mode of seed, all can sow in season more than a year, but be chosen in early spring (before March 20) and plum rain season arrive in (June) for best.Before sowing, tea place is intertilled once comprehensively, then the soil rake is thin, reject grass roots.Rainy weather by seed both be sprinkling upon uniformly on fine earth can, general every mu with grass seeds 0.5kg left and right.The tea place action row need not broadcast sowing seed.

Sow trefoil First Year, because clover is also more immature, need human assistance to weed out the rank grass and be beneficial to the strong growth of trefoil Zhu.After Second Year, reach the clover density of terraced wall in the ranks oneself is larger in tea place, forms turf, and oneself has not had the growing space of other weeds, has reached the purpose that suppresses weeds.Just can reach the purpose careless with grass system fully by this.

In addition, clover is not having sunlit position amount of growth very little, so clover can not laterally spread in tea tree root space.Having limited it can only (in the ranks) growth in fixed position.

When clover reaches the height of 30cm left and right, just can mow, at least can cut every year three to four times (with brush saw, mow and can significantly raise the efficiency), the mowing amount in annual every mu of tea place at least can reach 1500kg.Add the function with the root pomegranate bacterium fixed nitrogen of clover symbiosis, can meet the nutrient demand that tea tree nourishes and grows fully.
