Abstract

The invention relates to a taxus chinensis cutting orchard construction method. According to the method, a nursery land is selected at a moist dryland or farmland with deep and loose soil, high organic matter amount, good drainage, and no serious pest and disease; the land is prepared and fertilized, and is ditched for preparing beds; biennial seedlings bred from taxus chinensis seeds from high-quality provenance are selected, wherein robustly and vigorously growing seedlings with full buds an with an average seedling height of 50-55cm and an average base diameter of 0.8-1cm are selected for field planting; and managements such as shading, weeding and fertilizing are carried out in the cutting orchard. With the construction method provided by the invention, cutting orchard construction period is short, operation is simple, and cost is relatively low. A taxus chinensis large-area propagation and cultivation technical problem is well solved. With the method, taxus chinensis fine breed propagation level can be improved.

Description

A kind of construction method of cutting orchard of southern enqlish yew
Technical field
The present invention relates to a kind of construction method of cutting orchard of southern enqlish yew, belong to Chinese yew propagation technique field.
Background technology
Southern enqlish yew is taxaceae Chinese yew genus plants, mainly originates in the area on the south the Yangtze river basin, is China first class of protection plant.Southern enqlish yew dioecism, female plant pollination rate is by Effects of Factors such as weather, temperature, humidity, wind directions.Female plant energy result, but individual plant kind amount is very low, and also the seed dormancy phase reaches 1-2, and growth of seedling is very slow, brings very large difficulty to large area breeding and culturing.Current, the large tree of southern enqlish yew is very rare, for preserving and this rare tree of sustainable utilization, expanding the cultivation scope of southern enqlish yew, improving the quality of southern enqlish yew tree.
Summary of the invention
The object of the invention is to solve southern enqlish yew individual plant kind amount low, growth of seedling is slow, and the shortcoming of large area breeding difficulty, provides a kind of construction method of building the cutting orchard that the cycle is short, survival rate is high, with low cost.
The present invention adopts following technical scheme: a kind of cutting orchard construction method of southern enqlish yew, comprises the steps:
(1) selection on ground, garden: point selection is deep, loose at soil layer with building garden, organic matter is many, moistening, draining good, without nonirrigated farmland or the farmland of serious damage by disease and insect;
(2) make bed: three plough three rakes completing soil mid-January in winter in the first year to next year wholely, leveling hack, weed a garden, foreign material, stone, and using sufficient base manure, the amount of application of every mu of base manure is 20-25kg, and then every mu applies fertilizer 1000-1200kg again, deep ploughing is raked, then trench digging makes bed, height of bed 20-25cm, bedside l00-120cm;
(3) selection of seedling: select the biennial nursery stock that fine provenance Taxus chinensis var. mairei Seeds is bred, select average height of seedling 50-55cm, leading thread 0.8-1cm, robust growth, growing way is vigorous, the seedling planting that bud is full;
(4) seedling planting: southern enqlish yew is planted and selected to be advisable in resting stage, and overcast and rainy in the annual 10-12 month, plant during ground moistening, seeding row spacing is 55-60cm × 60-65cm;
(5) cutting orchard management: after field planting the 1st year and the 2nd year, southern enqlish yew grows to young growth by seedling to be needed to take cool canopy and shades, and use black shading screen covers, and light transmittance is 50-70%, and net height of shading is 2.5-3.5m; Annual 2-3 month carries out weeding, after weeding, ground organic fertilizer 400 ~ 600kg of annual four May every mu, composite fertilizer 15 ~ 20kg that N-P-K content is 1:1:1 is executed on eight September every mu ground, and every strain southern enqlish yew imposes fertilizer simultaneously, and the amount imposing fertilizer is 0.08-0.12kg/ strain, the annual 4-7 rainy season month, easily there is root rot, stem rot in southern enqlish yew, timely draining, keeps pavement without ponding;
(6) branch management: when southern enqlish yew coppice shoot up to carrying out determining bar during 8-12 cm, go weakly to stay strong, plant and only stay 1 coppice shoot then, within the 2nd year, stay 3 ~ 5 coppice shoots, within the 3rd year, stay 5 ~ 10 coppice shoots, within the 4th year, stay 10 ~ 15 coppice shoots;
(7) in 4 ~ 5 years after field planting, if when trunk top end grows water sprout, wiped out at liftoff 30 ~ 40 cm places every year, originally when the bottom branch stayed grows to 40-45 cm gradually, also cut at liftoff 30 ~ 40 cm places, branch to being formed with tree crown top layer is contour, and can grow well-balanced rudiment bar from same plane in the future, general field planting can form the crown of needs in 8 years;
(8) cutting orchard upgrades: cutting orchard upgrades once for 4 ~ 5 years, and to rotate crops, crop rotation is advisable, and veteran pile is grubbed out and removes, separately build Xin Pu; Or only to make the stump riglet of 2 years on ground, garden, the 3rd year after adopting article each pile stay 1 coppice shoot, then three end of the year 1 year seedling pile cut out afforestation, and separately build Xin Pu;
(9) extermination of disease and insect pest of cutting orchard: southern enqlish yew is adopted when fringe is set annual rudiment stripping and adopts bar in a large number and easily damage by disease and insect occurred, and should process the residual leaf of deadwood in time and carry out the extermination of disease and insect pest.
Further, the composite fertilizer of base manure to be N-P-K content be 1:1:1 in described step (2).
Further, described fertilizer is adopt the fermentation of southern enqlish yew branches and leaves to make completely.
Further, for preventing fringe bar from breaking up in described step (6), the axillalry bud that coppice shoot grows must be extractd in time to the type easily producing Secondary Branch, the high girth growth plucking top method or priming leaf method suppression advantage bar can be adopted to eugonic tree-shaped, when plucking top when height of seedling reaches 30 ~ 40 cm, the terminal bud of coppice shoot the highest on pile is extractd, impels two coppice shoots of living again below wound.
The cutting orchard construction period of building in the present invention is short, simple to operate, and cost is lower, preferably resolves the technical problem of southern enqlish yew large area breeding and culturing, can improve the stock breeding level of southern enqlish yew.
