Description

A kind of release grass is no-tillage turns over tea place

Technical field:

This utility model relates to tree plant cultivation field, is specifically related to a kind of exempt that grass is no-tillage turns over tea place。

Background technology:

Along with improving constantly of living standards of the people; the demand of Folium Camelliae sinensis improves year by year; domestic and the export volume of Folium Camelliae sinensis all presents straight line and increases, and Folium Camelliae sinensis has the economic plants of development potentiality most as China, carries out scale Tea planting and has become the important channel of increasing peasant income, rural prosperity。But weeding in the cultivating process of tea place, dig and still exempt to turn over without ideal scheme realization release grass, at present can only by being accomplished manually, weeding and the labor intensity digged are very big, along with increasing of rural labour migrant worker, the personnel overwhelming majority being engaged in Tea planting is old people and women, these personnel's muscle power are thin, unable competent, tea grower is only by strengthening power work the season employing high price to complete weeding and to dig, requirement is managed according to Tea planting, tea place is in the spring, summer, Qiu Sanji is required for weeding, minimum every year need weeding three times, to prevent farmland running to weeds, reduce weeds and Camellia sinensis to strive water and strive fertilizer and win honour for, make Camellia sinensis can obtain the moisture needed for normal growth, nutrient and illumination, guarantee the quality and yield of Folium Camelliae sinensis。

It is known that weeds are one of principal elements affecting tea place tea shoot survival rate, Camellia sinensis quality and tea yield。In young tea plantations, the area exposed due to earth's surface is maximum, very easily grows weeds。Weeds and tea shoot strive water, strive fertilizer, to strive sunlight problem very prominent, if removing tea Tanaka weeds not in time will affect growth of tea plant and survival rate。Increase the first three years educated in tea place, remove the emphasis that weed in tea garden is management in time。When Camellia sinensis enter mining phase, the maintenance in tea place should weeding in time, oxygen supplement of on time digging again。

In tea place, weeds are of a great variety, there is section more than 30, the kind more than 80 such as liana weeds in grassy weed, broad leaved weed, sedge weed, annual grassy weeds, broad leaved weed, many of which weeds are the vectors of disease and insect such as leafhopper class, aphid, demodicid mite class, once it is weedy, the tea shoot transplanting survival rate of asexual cuttage can sharply decline, and even has situation about being annihilated to occur。

Weed in tea garden intrusion feature very wide spectrum, when garden is built in new tea place, residues in the ruderal species and perennial weeds perennial root last year in soil, is all the main source that occurs of weed in tea garden；Weed in tea garden wide material sources can bring tea place into seedling allocation and transportation such as: some weed seed or plant；Surrounding roadside, tea place, limes marginis weeds plant seed, rack and deliver in tea place；Drift weed seed in the pond of tea place water, irrigation canals and ditches or cistern, brings tea place into by spraying water or pouring water；Use the dung polluted water not become thoroughly decomposed and without in the Organic substances such as the turf of high temperature retting, straw, fruit, compost, be often mixed with weed seed alive, be grown to serve as weed in tea garden；The activity such as the mankind and birds, brings tea place into by weed seed, such as Fructus Xanthii, Herba Bidentis Tripartitae, cuts the shell band viscosity burr of the seed of clothing, easily sticks on the body of clothes Huo Keru garden animal of people, enters tea place。

The kind of weed in tea garden is extremely many, the fast growth of weeds, removes workload very big, rely on artificial altofrequency weeding not only labor intensity big, and time and effort consuming, work efficiency are low, cost is high, if tea garden management personnel weeding not in time, weeds will prosperous length, directly affect the growth of tea shoot。Simultaneously in weeding process, if weeding system is improper or weeding imprudence, also can damage the tea shoot that goes out。If can cause again with chemical weed control, pesticide residues exceed standard, and affect tea leaf quality, if over administration is also easy to make Camellia sinensis cause poisoning, even make tea shoot dead because of poisoning；Use in tea place chemical herbicide also can pollute Folium Camelliae sinensis simultaneously, cause Pesticide Residues in Tea amount to exceed standard；Composition in herbicide residue soil also can microorganism in spoiled soil, soil insect and other toy structure of community, destroy the normal configuration of tea garden soil rhizosphere bio-diversity。Current people show great attention to food safety, and people are necessary not only for Folium Camelliae sinensis, with greater need for organic tea, therefore, advocate physical weed control, and stopping chemical weed control is the inevitable development direction that tea garden management is safeguarded。

In order to alleviate the hardship of the weeding of tea grower, in order to reduce the weed growth in tea place, realizing exempting grass, current people adopt rice straw mulching method and covering with ground sheeting method in tea shoot initial planting, wherein, although rice straw mulching method has the effect suppressing weeds to generate, but the growth of weeds can not be stopped, meanwhile, be laid on the Caulis et Folium Oryzae in tea place, Caulis et Folium Oryzae easily grows worm's ovum, increases Folium Camelliae sinensis and cause the probability of pest and disease damage。Under summer high temperature environment, it is laid on the very easily initiation fire of the Caulis et Folium Oryzae in tea place, it is easy to burning tea place, consequence is hardly imaginable。

Although the weeding herbicide effect of covering with ground sheeting method is better than the former, tea place can be reached and exempt from herbicidal effect, but mulch film had both blocked rainwater and had flowed into the passage of tea garden soil, has completely cut off again the interchange channel of tea garden soil and ambient atmos, has directly affected the breathability of tea garden soil, soil easily hardens, be not easy to daily fertilizing management, meanwhile, mulch film be easy to breakage also easily by wind from, the weeds once occur still overgrowing, existing physics weed eradication scheme is all undesirable。

Plough oxygen supplement of loosening the soil of tea place is one of the important process of tea garden management, all must plough and loosen the soil annual winter in tea place, and tea field minimum to be ploughed deeply once in annual winter, through freezing pineization, to improve the breathability of soil。Soil is particularly significant for the survival rate of raising tea shoot and the normal growth of Camellia sinensis by freezing pineization。Loose soil gap is more, and these soil gaps are the passage that outside air enters soil, is also the passage of extraneous rainwater entrance soil, the also passage of soil sterilization toxin expelling, if soil compaction, outside air, rain penetration will be affected in soil, directly affect the growth of Camellia sinensis。

Turning in tea place is the main method of the existing raising gas permeability of soil, but existing turn over essentially by manually realizing, not only labor intensity is big, cost of labor is high, and it is easy to damage tea root, plough effect simultaneously and be subject to the restriction of anthropic factor, plough quality cannot be guaranteed, on the other hand the garden that frequent enters into is needed to carry out picking tea-leaves operation in the time of picking tea-leaves due to tea grower, Camellia sinensis ground surface soil in the ranks is all repeatedly trampled by people and is hardened, increase the labor intensity of operation of turning over further, turning over for tea grower in tea place is a cumbersome and time consuming job, the hope that tea grower is urgent is freed from the hard work turned over。In addition farming can make soil organic substance content reduce, especially in sloping fields tea garden, topsoil knot holding force after turning over reduces, very easily washed away loss by heavy rain, the upper strata organoclay (being commonly called as mellow soil) making tea place runs off, reducing the utilization rate of tea place fertilising and the normal growth of Camellia sinensis, meanwhile, degree of depth farming also can damage tea root。

At present, although people have been developed that Folium Camelliae sinensis tillage machinery, but this kind of machinery is only suitable for tea shoot initial planting, when Camellia sinensis Feng Hanghou then cannot enter garden operation, meanwhile, Camellia sinensis operation process can destroy tea root。And this kind of machinery has high input, operating technology requires height, and general tea grower will not purchase without operation。

Therefore must the scheme looked for more preferably of section replace, to improve the breathability of soil。

In tea tree planting cultivating process, fertilising is requisite in good time, but the fertilizer effective rate of utilization in existing tea place is very low, according to existing reported in literature, the existing utilization rate of fertilizer in tea place is less than 30%, although tea grower's dose is relatively big, but reality by Camellia sinensis absorb too low, so not only increase the dose in tea place, add the planting cost of tea grower, and Polluted area water system understood by the fertilizer run off, destroy the living environment of people。Equally, existing tea place does not have water conservation containment structures, and the utilization of rainwater is not high yet。

According to statistics, current one mu of tea place every year weeding with turn in cost be about 2000 yuan～2500 yuan, further raising along with people's material conditions, increasing peasant will abandon work and plant Tea Industry greatly by force, the labor wage of rural labour will be further up, therefore tea place weeding also will rise with the expense turned over, what more have a headache is need weeding and the time turned in tea place, the strong labor in rural area is very in short supply, often the rich phenomenon that can not find people occur, therefore the cost of tea place plantation will be more and more higher。Simultaneously as the utilization rate of fertilizer in existing tea place is only about 30%, the fertilizer great majority that tea place applies, along with water loss, had both added the planting cost of tea grower, produced to pollute to regional soil, water system environment again。

Tea grower is highly desirable can find a kind of can exempt grass, exempt to turn over, new departure trained by the modern tea place pipe of water conservation fertilizer conservation。
