Specific embodiment

Specific embodiments of the present invention will be described in further detail below.

It mainly include that prepartion of land is handled present invention is generally directed to the Paris polyphylla plantation under clayed soil, soil affiliated facility Building and plantation after management harvesting.

Since clayed soil water-retaining property is preferable, ventilative water permeability is poor, is mainly suitable for the plant growths such as rice, makees to preceding stubble After object harvest, by soil, wind is dried under field conditions (factors), and after moisture evaporation, to beating rotary cultivator can go to the field after smooth operation, Real tillage 20-30cm, and by the cake scattering that agglomerates in soil, evacuate soil sufficiently, then whole block of raking.

In the soil put in order, rough sand is added by original soil and rough sand (such as thick river sand or rough sand soil) volume ratio 1:1, It is sufficiently mixed uniformly with rotary cultivator again, makes original soil and rough sand mixed layer up to 10-12cm, then plot surface raked whole.

After prepartion of land, compartment trench digging is carried out out to soil, i.e., constructs a plurality of parallel bar shaped protuberance Tu Duo on soil The compartment of plantation seedling is formed, is ditch between compartment.

When opening compartment, compartment face width is 120cm, and ditch depth 20-30cm between every compartment, eminence trench depth 20cm, lower ditch depth Spend 30cm, furrow width 30cm；Compartment face width 120cm is conducive to later period weeding, when trench digging, so that the ditch between every compartment is formed domatic ditch, i.e., The deeper other end in one end of ditch is shallower, utilizes draining.The clay generated when by trench digging is uniformly dissipated in compartment face after sufficiently breaing up.

It is humous with a thickness of 2- uniformly all over spreading fertile soil and decay sheep excrement or pig manure on the compartment face put in order 3cm, decay sheep excrement or pig manure with a thickness of 1-2cm, then with small shape rotary cultivator by fertile soil or sheep dung (or pig manure) with changed early period Good sandy loam is sufficiently mixed uniformly and compartment face of raking, when cultivating Paris polyphylla by fertile soil and decomposed animal wastes and sandy loam The effective arable layer formed is not less than 12 centimetres, up to 13-16cm.

Animal wastes are mixed and added into using sandy soil and fertile soil, make loosing soil, it is big containing fertilizer amount, it is easily permeable and ventilative, Paris polyphylla root system suitable for transplanting sufficiently draws nutrient and moisture, improves survival rate.

Paris polyphylla blade meet the sun directly shines after easily wilt, blade wilt after can not carry out photosynthesis and synthesize effectively at Point, Paris polyphylla underground stem tuber current year will not expand, and seriously affect yield.Therefore, it after the completion of site preparation and soil improvement work, needs to take Sunshading facility is built, when taking sunshading facility, selects the sunshade net of new material processing, sunshade rate is about 75%.Step 1: in field Block surrounding is that 32mm steel pipe is driven underground with diameter, and depth about 50cm, every two steel pipes spacing distance 4m, steel pipe upper end is apart from ground Table 1.8m forms sunshade rack；Step 2: being banded in the top of steel pipe with No. 14 thin wires, drawn between the corresponding steel pipe in field Tight thin wire, intersecting between different corresponding thin wires, it is latticed to be formed, and latticed thin wire plays the work for supporting sunshade net With.If field area is big, distance is remote between corresponding steel pipe, when thin wire steps on sunken, can stand again in field a certain number of Steel pipe, then vertical steel pipe quantity to be can support iron wire very well, iron wire is not stepped on fall into until.Step 3: outside stood steel pipe top then, It is outer then away from welding card slot at earth's surface 1.5m and 0.02m, be used for later period circlip clamping sunshade net.

Irrigation and drainage drainage facility is the key that ensure that Paris polyphylla is transplanted seedlings to survive especially have half a year more times every year in some ecotope It has no rainfall, compares concentration when rainfall comes again, and rainfall is very big, irrigation and drainage drainage facility, which just seems, to be even more important, and pours drainage facility It is simple to operation using wanting very convenient.It is as follows to build facility key step of pouring water: first, it is closed in Paris polyphylla planting site from water source Suitable distance determines the water main and branch water pipe of facility of pouring water according to the size of Paris polyphylla ground area.General water main uses straight The PE that diameter is 5.0cm is managed, and branch water pipe is managed using the PE that diameter is 2.5cm.Second: water main is by pressure pump (according to field Size determines pump pressure size) be connected with water source tube after, then with what 5.0cm became 2.5cm become threeway and diameter as the PE of 2.5cm pipe It is connected, connects shut-off valve at distance connection 20cm.Distance 3-4m between branch water pipe on water main, the length of branch water pipe according to Depending on ground block length, water pipe end blocking cap tube sealing.Third: the punching access rotation of the position 2.5-3.0m is spaced in branch water pipe Spray head, rotary nozzle use the suit G type rotary nozzle of Zhejiang Le Miao company production, which sprays water diameter under maximum hydraulic pressure Up to 4m；Branch water pipe tension is mounted on the thin wire of sunshading facility, and ties jail with thin iron tied silk, cannot be stepped on sunken.4th: filling It irrigates after facility builds up, opens shut-off valve and pump power pressurization on distributive pipe and draws water, check whether each G type rotary nozzle is uniform Water spray, if there is water supply failure, then checks one by one and debugs, normal until spraying water.

When Paris polyphylla is cultivated, draining and water supply are equally important, and impeded drainage is the master that Paris polyphylla underground stem tuber does not expand and rots Want factor.Directly Paris polyphylla milpa can be discharged in water by the slope drainage ditch between hillside fields, the compartment face Mian Yuxiang, do not influence Paris polyphylla If growth needs special pumping equipment, it is as follows to build special pumping equipment key step meet smooth relief or lowland: the One: according to landform, the appropriate location in Paris polyphylla plantation plot is selected to open main drain, ditch highest point 20cm, bosom 30cm, shape At domatic ditch, furrow width 40cm, then ditch both sides are built into waterwall with brick, prevent soil from falling at any time and hinder later period row in ditch Water；When opening compartment, the domatic gutter low side between the face Mian Yuxiang of compartment is connected with tap drain, convenient for the water between the face of compartment in gutter Into in tap drain.Second: deep-cut tank in tap drain innermost position, tank size depending on Paris polyphylla milpa size, Soil is prevented to fall into pond at waterwall with brick around tank.Third: sewage pumping is put in tank and pumps one, is taken out The size of water pump generally can go out sewage by fast pumping in time with the suction pump of 1.5KW depending on the size that Paris polyphylla is planted, it is ensured that Paris polyphylla underground stem tuber is not impregnated by too many moisture, can normal growth.

It is 75% sunshade net in the sunshade net support frame upper cover sunshade rate having in advance, lid hides after irrigation and drainage drainage facility is built up Firmly it should all tense and be caught in card slot with the sunshade net surrounding of surrounding at the top of planting site when screened postive, winter is because of wind-force in order to prevent Sunshade net is blown brokenly very much greatly, the upper surface of sunshade net must push down sunshade net with the film press mold for building greenhouse is pure at the top of planting site, And press mold is pure needs to be banded at the top of corresponding supporting steel pipe.

Before Paris polyphylla transplantation of seedlings, opens G type rotary nozzle and spray Paris polyphylla milpa water thoroughly, until there is small part water from compartment Face earth's surface infiltrates into gutter, while checking whether the soil under the earth's surface of compartment face within 15cm has all been waterlogged.Finally Moisture excessive on the face of Paris polyphylla milpa compartment need to be evaporated under field conditions (factors) in right amount, but still need to make soil at moisture state, had Paris polyphylla seedling is transplanted in compartment face conducive to operator and seedling survives.

The annual 4-6 month, the Paris polyphylla seedling with the wild Paris polyphylla seedling of excavation or manually cultivated are planted, in the 10-11 month, It can be cultivated with Paris polyphylla lateral bud.It is when plantation, bud is upward, root system is sufficiently dredged expansion, blinding about 5-8cm is used when lateral bud is too long Native all covering bud-ends.Line-spacing 15-20cm, spacing in the rows 15-20cm, the seedling at both ends is apart from compartment face edge 10cm, every row plantation weight 6 plants of building seedling, 12000-13000 plants of Paris polyphylla seedling is planted per acre.

The Paris polyphylla seedling of cultivation root system in excavation is largely damaged, such as main root or fibrous root fracture, root Hair is impaired etc., therefore while cultivating Paris polyphylla plant should be watered with root water, promote root system to restore the fertilizer sucting ability that absorbs water rapidly, on the day of ensureing The plant survival planted.Such as: under normal circumstances, two operators cultivate seedling, operator's watering, watering When, it is soaked in every plant weight building seedling root and fills tap water 500ml.When later period waters daily, weight is sprayed with the spray irrigation system mist built up Building seedling, every sky fog spray number can be depending on the gentle degree of Paris polyphylla blade and compartment face earth's surface, when general the Heavenly Stems, every sky fog spray Once, each mist sprays 20 minutes.

The middle ten days and the last ten days of the second year 4-5 month, checks field after Paris polyphylla transplanting, checks for plant with wood sled or small spades (underground stem tuber) phenomena of mortality, timely leakage detection are filled a vacancy, and guarantee full stand and enough density, increase economic well-being of workers and staff.

After Paris polyphylla transplantation of seedlings to field, the work of the weed seed of suppressing weed seed germination or other fields in soil in wind-force , therefore every year will be according to how much development artificial weedings of weeds in field with the growth for influencing Paris polyphylla after the lower emergence into Paris polyphylla plot Work 2-3 times.1-2 after Paris polyphylla kind transplantation of seedlings, available iron, which is uprooted, gently digs weeding or manually pulls grass, and 3-4 is used as far as possible Grass manually is pulled, few to be hoed up weeds with iron, growth and branch due to Paris polyphylla subterraneous root are interweaved together, if uprooted with iron Grass can hurt root, influence absorption of the Paris polyphylla root system to nutrient in soil.Herbicide weeding can not be used, herbicide can injure Paris polyphylla Ground seedling and underground stem tuber can also influence the drug effect and quality of Paris polyphylla because of herbicide residue etc..

The annual 3-4 month, when ground temperature rising root system starts growth, per acre with fermentation cattle and sheep stable dung or farmyard manure 2000- 3000kg, for nutriment to Paris polyphylla root system after rainwater infiltration, meets the need of its growth all over the compartment face for planting and having Paris polyphylla is spread on It asks.

Under the sun directly solarization state, Paris polyphylla blade and floral organ are easily dried by the sun, cause plant withered and dead.Therefore Field sunshade management work is carried out to be even more important.Sunshade management can be performed in terms of following two: first is that November current year, When Paris polyphylla seedling disappears substantially after seedling and second year April, Paris polyphylla seedling was not emerged also, sunshade net is removed, the sun is allowed directly to shine Paris polyphylla earth's surface, increased Add soil ground temperature, promote Paris polyphylla well developed root system, improves absorption of the Paris polyphylla root system to nutrient in soil, be conducive to second year Paris polyphylla and go out Growth of seedling is healthy and strong when seedling；Second is that restore the sunshade net that sunshade rate is 75% when Paris polyphylla is emerged, when there is bud in cultivation Paris polyphylla, Sunshade net needs Factory to open between the sunshade net support frame surrounding 1.5m-2.0m of field, is conducive to ventilated and florescence insect counterweight The pollination in building is fertilized.

When the annual 11-12 month is there is no rainfall or rainfall are seldom, begin with rainfall the second year 1-5 month, the arid time compared with Long, when up to half a year, soil surface water evaporation rate is fast, therefore the moisture in soil is kept to be very important, should be every Watering in one week is primary, and when watering, which should be noted that, is watered with soil moisture, ensures that Paris polyphylla root system has moisture absorption (or to check field soil water Point situation, 40% or more dry season soil moisture with)；The annual 6-9 month, rainwater is more, is sometimes heavy rain, it should be noted that draining in time, Prevention waterlogging, otherwise Paris polyphylla underground stem tuber can rot because soil ponding is excessive, cause to be short of seedling, influence economic well-being of workers and staff.When plumbing Use the G type rotation spray irrigation system and sewage pumping pump in irrigation and drainage facility.

The Paris polyphylla florescence generally in the 4-6 month, is basically completed Pollination Fertilization process July, and the seed collection time is the 9-10 month.Paris polyphylla Fruit category berry, seed growth development to certain phase, berry cracking, seed gradually expand, seed aril progressive additive, slurry The weight of fruit increases.With the continuous development of Paris polyphylla seed, Paris polyphylla seed weight increases, and Paris polyphylla plant is difficult to support berry, makes Plant bending, berry contact ground, greatly and the influence of the microorganisms to seed such as bacterium because of soil moisture content, cause the corruption of Paris polyphylla seed It is rotten.Therefore, between Paris polyphylla berry expansion period, staff should observe repeatedly in Paris polyphylla field, the bending of discovery plant and berry Should be as early as possible with branch and cord by plant righting when ground, and erect plants to paddle fruit maturation is allowed to harvest.

It when harvesting Paris polyphylla seed, should be picked according to the maturity of berry in different plants, when picking mainly sees berry Breach corner dimension and seed aril thickness and easily de- degree judged.Paris polyphylla seed after harvesting should be stored in sky In the logical environment of air-flow, and spray amount of water, pays attention to it is anti-mildew and rotten, moisture number to keep the aril original sample to be Preferably.Generally answer sowing in time, if could not sowing in time, can also at 4 DEG C deepfreeze, and it is suitable that seed should be allowed to maintain Moisture.

In Paris polyphylla cultivation, various diseases may be met with, powdery mildew and anthracnose are prevented and treated, with 50% wettable of carbendazim Pulvis is watered by spraying by 1:300 times of liquid, and primary every mist spray in 1 week, general mist sprays 2-3 times；Damping-off, samping off are prevented and treated, is used 1 part of 50% wettable powder of carbendazim, is sprinkled into Paris polyphylla ground after being uniformly blended into half-dried fine earth 1000-1500 parts；Subterranean pest-insect can eat Young shoot, seedling or the rhizome of Paris polyphylla, are caused phenomena such as being short of seedling, and common subterranean pest-insect has grub (chafer), wireworm (to kowtow Worm), mole cricket (mqb), cutworm (cut worm), can be selected low toxic pesticide " phoxim " 1:1000 times of liquid, mist be sprayed on earth's surface or On plant leaf and stem, and insect pest incidence is observed, determines subsequent mist spray number.

When reaching 3-4 to growth period after Paris polyphylla seedling culturing and planting, in the 11-12 month, the powder of Paris polyphylla underground stem tuber accumulation Matter content can harvest underground stem tuber when reaching current year highest.When excavation, with tools such as hoes gently since Paris polyphylla stem tuber side, Soil is removed, Paris polyphylla underground stem tuber is taken out, it should be noted that keeps stem tuber complete.After taking out Paris polyphylla underground stem tuber, remove on stem tuber Soil, and scrubbed clean with clear water, it dries.If meeting rainy day or cloudy day, can be dried at 40 DEG C or less with baking oven.In addition, Paris polyphylla stem tuber diameter is too big and longer when being not easy dry, and the slice re-dry of 1cm or so can be cut into tools such as knives.

Previously described is each preferred embodiment of the invention, if the preferred embodiment in each preferred embodiment It is not obvious contradictory or premised on a certain preferred embodiment, each preferred embodiment can any stack combinations Use, the design parameter in the embodiment and embodiment only for the purpose of clearly stating the inventor's invention verification process, and It is non-to limit scope of patent protection of the invention, scope of patent protection of the invention is still subject to the claims, all It is that similarly should be included within the scope of the present invention with the variation of equivalent structure made by description of the invention.
