Abstract

The invention discloses a cultivation method for Magnolia grandiflora Linn, belonging to the field of tree cultivation. The method comprises the following steps of: digging a farmland for 60cm deep to prepare the land in winter, conducting permanent planting cultivation to 1-year-old to 2-year-old Magnolia grandiflora Linn grafted seedlings, conducting spaced-plant transplanting within the last ten days of March to the beginning of April after two to three years, conducting pruning in spring and summer within three years after transplanting, keeping the height of a crown to be one third of the height of a tree, ensuring that a trunk does not have crotches at a position below 1.6m to 2.0m, pinching and removing unwanted sprouts in time and focusing on cultivating the trunk. By conducting scientific and effective cultivation management to the Magnolia grandiflora Linn through field planting, transplanting, water manure management, shaping and pruning, the survival rate of the grafted seedlings at an early stage can be well ensured, the development of the root systems of the grafted seedlings and the growth of the trunks are promoted at the same time and the growth speed and the seedling quality of the Magnolia grandiflora Linn are further improved through pruning. By adopting the method, the diameter of the cross-section of the tree trunk of the Magnolia grandifloraLinn can grow 2cm to 3cm every year and can grow to 12cm to 15cm when the Magnolia grandiflora Linn is 5-year to 6-year old.

Description

The cultivation method of a kind of wide yulan
Technical field
The present invention relates to the cultivation method of a kind of forest, relate in particular to the cultivation method of a kind of wide yulan.
Background technology
(formal name used at school: magnolia grandiflora linn) belong to Magnoliaceae, have another name called evergreen magnolia, bull bay originates in America to wide yulan, evergreen megaphanerophyte, high 20-30m.Filbert or the grey of bark is thin flakey cracking.Wide yulan growth happiness light, slightly anti-the moon during the children.Happiness warm and moist weather has certain cold tolerance.Flue dust and sulfur dioxide gas are had stronger resistance, and damage by disease and insect is few.Root system is deep and broad, and wind resistance power is strong.Particularly the tree seedling trunk is tall and straight, and tree vigo(u)r is grand, strong adaptability.Wide yulan tree performance is graceful, and evergreen all the year round, damage by disease and insect is few, thereby is good avenue tree planting, not only can provide necessary giving shade for the pedestrian in summer, can also beautify well streetscape.
The breeding of wide yulan is generally selected kind to broadcast, press strip and grafting method.Plant and broadcast general late September seed collecting, the sowing of late Febuary in next year; Press strip generally selects life in 2~3 years to enrich side shoot sturdy, that upwards carry out, carries out with mid-April~mid-May; Grafting is carried out cut-grafting generally take yulan magnolia, purple yu-lan (Magnolia liliflora) as stock before germinateing early spring.The nursery stock of traditional seedling raising manners is slow in this area growth rate, drought resistance, lodging resistance, poor water resistance, and transplanting survival rate is low.
Summary of the invention
Goal of the invention: the purpose of this invention is to provide the cultivation method of a kind of wide yulan, be used for short cultivation and go out tall and straight, the colory wide yulan of trunk.
Technical scheme: for achieving the above object, the cultivation method of a kind of wide yulan of the present invention, its method comprises: in the site preparation and fertilization in winter, 60 centimetres of dark carrying out wholely are dug in the field, every mu of basal dressing comprises: 800~1200 kilograms of chicken manures, composite fertilizer's 80~120 kg, or whenever apply 300~500 kilograms in cake fertilizer, 100~200 kilograms of the composite fertilizers of becoming thoroughly decomposed; The wide yulan grafting field planting of life in 1~2 year is cultivated, and spacing in the rows is 1.8m~2.5m, and line-spacing is 1.0m~1.8m, carries out transplanting every strain after 2~3 years at the beginning of late March to 4 month, and spacing in the rows is 1.8m~2.5m, and line-spacing is 2.0m~3.6m; In 3 years after the transplanting, prune in spring, summer, keeping height of tree crown is 1/3 of the height of tree, trunk under 1.6m~2.0m without bifurcated, in time pinching, except sprouting, and emphasis is cultivated trunk.
Wherein, site preparation and fertilization is divided into according to field loosing soil degree and entirely cultivates wholely and two kinds on the whole ground of ditching.If field soil compaction, the root root and stem of certain plants are more, should be with entirely cultivating whole ground.Entirely cultivate is first base manure to be applied in the field wholely, then adopts excavator entirely to cultivate soil deeptillage, and the degree of depth reaches 60 centimetres, the cleaning root root and stem of certain plants, and around digging and the drain ditch at center.To the loose field of world soil, comprise the paddy field, should adopt the trench digging method of soil preparation.It is 60~100 centimetres that trench digging is held successfully wide with excavator wholely, deeply reach 60 centimetres plantation ditch, table soil and core soil are placed on respectively the both sides of plantation ditch, spread straw into 10~15 cm thicks planting the ditch bottom, to show soil after cutting down and insert in the ditch 20 centimetres through freezing, again basal dressing.
Wide yulan of the present invention is adopted the grafting method breeding, described grafting in March~April by obtaining at stock with the wide yulan scion grafting of terminal bud.Described stock adopts yulan magnolia, purple yu-lan (Magnolia liliflora), and interface is liftoff 5~10 centimetres during grafting.
The present invention after by grafting field planting and the transplanting after the field planting, adjust planting density on the one hand, the more important thing is the growth that promotes root system, and cooperate trimming and finishing to promote the growth of trunk.The soil bulb diameter is 10 times of grafting rhizosphere diameter during described grafting lifting, and uses the straw rope colligation, prevents from breaking up native ball in the handling process.Plough deeply first whole ground when wide yulan is transplanted, transplant after using sufficient base manure.Dark 2 centimetres than rhizosphere place of transplanting depths shorten lifting to the time of transplanting as far as possible, nursery stock is rectified, and watered normal root water.
The first two years artificial weeding after the described wide yulan field planting adopted sweet peaceful, anti-this of standing grain of grass to carry out weeding in 2 years afterwards.
The First Year of field planting does not apply fertilizer after the grafting, and from the second year, annual early spring (late March), every strain applies each 0.3~0.5 jin of urea and composite fertilizer.Fertilizing method: in 20~25 centimetres of dark caves of delaying of wide yulan seedling collar 30 centimeters excavation, two kinds of fertilizer mixing are applied, will build after applying and tread Dang Kou.
Beneficial effect: the cultivation method of a kind of wide yulan of the present invention carries out science, effective cultivation management by field planting, transplanting, water and fertilizer management, pruning each side to wide yulan, promote the growth of grafting root system when the grafting of trying hard to keep in early days survives and make trunk grow, by growth rate and the nursery stock quality of pruning the wide yulan of further enhancing, adopt method provided by the invention can make diameter of a cross-section of a tree trunk 1.3 meters above the ground every year of wide yulan with the speed increment of 2~3cm, the wide yulan of 5~6 seedling ages can grow to 12~15 centimetres.
