Description

A kind of new implantation methods of white poplar (GKT88 poplar)
Technical field
The invention belongs to white poplar " tree south, north is planted " planting technology field, particularly relate to a kind of white poplar
The new implantation methods of (GKT88 poplar).
Background technology
White poplar (latin name is Populusalba), belong to northern species broad leaved forest class, tamed after breeding and can be planted in south, can fast-growing after plantation, ten times can be regenerated after felling, belong to the State Administration of Forestry's " tree south, north is planted " promotion project, it is very little that the rear demand to water is bred in white poplar domestication, water absorption is 20% of common species, and after becoming a useful person, more than 15m trunk is without branch, the area plantation below suitable southern 2500m height above sea level.
The implantation methods of existing white poplar mainly adopts branch seedling method to carry out nursery lot cottage breeding seedling, triennial nursery seedling transplants plantation of going up a hill after high-order chipping, employing the method is planted, after 3 ~ 5 years, white poplar cannot normal growth, 5 ~ 6 years sick bearing tree trunks, tree crown easy moth, cause lumber recovery lower, planting cost is high, business efficiency is low, should not regenerate.After adopting existing implantation methods to plant, the every per mu yield of white poplar of life in 4 years is about 10 tons, and cane moth disease is serious, and directly cause production declining, wood quality is on the low side, and the plantation of common Fast growth poplar usually uses agricultural insecticide, diseases prevention, cures the disease, and environmental pollution is serious.
Summary of the invention
For the deficiencies in the prior art, the invention provides the new implantation methods of a kind of white poplar (GKT88 poplar), described new implantation methods comprises trunk cuttage technique and low level chipping technology, and the GKT88 poplar growth cycle that plantation obtains is short, regeneration capacity is strong, the region of suitable planting is wide, and damage by disease and insect is few, and lumber recovery is high, wood quality is high, environmental influence is less, high financial profit, is applicable to Pulp-Paper Timber Forests and standing timber plantation.
Technical scheme of the present invention is as follows: the new implantation methods of a kind of white poplar (GKT88 poplar), comprises the following steps:
Step (1) digs kind of a plant hole plantation GKT88 poplar seedling during annual rainy season;
Step (2) after planting Second Year February ~ the first tenday period of a month in March by the tree root of GKT88 poplar cane with upper part low level chipping;
Water after step (3) GKT88 poplar cane low level chipping and promote that it germinates, after growing 1 ~ 5 leaf, implement fertilizing, watering weeding management, after growing 3 ~ 4 years of 1 ~ 5 leaf, grow up to GKT88 poplar bearing tree.
The bright GKT88 of the utilization poplar of this law can regenerate the characteristic with fast-growing, adopts trunk cuttage during plantation, after its plantation is passed the winter, adopts low level chipping technology, make it regenerate to it.After regeneration, growth rate is accelerated, and damage by disease and insect reduces.Low level chipping is after six months, and GKT88 poplar can grow to more than 5 meters, and the diameter of a cross-section of a tree trunk 1.3 meters above the ground is 2 ~ 3cm, and after 3 ~ 4 years, GKT88 poplar grows up to GKT88 poplar bearing tree, and stem is high more than 25 meters, and the diameter of a cross-section of a tree trunk 1.3 meters above the ground is more than 20cm.
The reason that in described implantation methods, the growth rate of GKT88 poplar is fast and damage by disease and insect is few is: arrive winter after GKT88 poplar seedling plantation some months, the nutrition of GKT88 poplar root absorption is limited, energy storage is not enough, and GKT88 poplar seedling is now in morbid state, and continued growth speed can be fallen slowly, by its root with after upper part low level chipping, GKT88 poplar root is just in recuperation state, accumulation nutrition, after germinateing spring, its growth rate is accelerated, and damage by disease and insect also can reduce.Interplant insect-pest plant thorn vest, Pistacia weinmannifolia and Litsea pungens simultaneously, play the effect reducing insect pest.
Described GKT88 poplar seedling is tame the white poplar seedling of breeding through soil, weather, environment and plant chain.
GKT88 willow seedling described in step (1) is bagged seedlings, and the cultivating process of described bagged seedlings is as follows:
2 ~ March gets the healthy seedling trunk (cuttage seeding) of 1 year 1 ~ 3 term life from GKT88 poplar seedling nursery lot, and cuttage kind value, in nutritious bag, obtains bagged seedlings after growing to 100 ~ 200cm; The healthy seedling trunk stem height 5-7m of described 1 year 1 ~ 3 term life, more than diameter 3cm, buried during cuttage plantation end shearing 20 ~ 25cm, stay 2-3 bud (radical bud), cut the inclined-plane being cut into 40 ~ 50 ° of angles, with bore 10 ~ 15cm, the nutritious bag of long 15 ~ 25cm carries out packed, dress head from packeted soil plane 1 ~ 2cm, its top is cut and is cut into plane, cuttage seeding trunk is straight, thickness is well-balanced, bud luxuriant full, without damage by disease and insect.
The healthy seedling of described 1 year 1 ~ 3 term life: GKT88 poplar is in nursery lot plantation during 1 ~ 3 year, and the growth of seedling that annual chipping back root part grows obtains healthy seedling in 1 year.As a term annual healthy seedling refers to GKT88 poplar after nursery lot plants 1 year, by trunk chipping, namely the growth of seedling that then root grows obtains a term annual healthy seedling for 1 year.
The healthy seedling trunk (cuttage seeding) of described 1 year 1 ~ 3 term life is in bag before cuttage plantation, root process is urged to it, 12 ~ 24h is soaked with 0.01 ~ 0.02% Nafusaku solution, or by ABT1 root-inducing powder 80 ~ 150 mg/kg, solution soaks 1 ~ 3h, after urging root process, plantation survival rate can be significantly improved, reach more than 99.5%.
Selection and the process of cuttage seeding should note following aspect: one is to observe further and to select seedling, seedling upper end does not have lignification or the incomplete part of lignification and plants that bar lower end is thicker, comparatively bending, the luxuriant less part of bud should cut out, and chooses mid portion as seedling.Two is note the lower end (bury end) of cuttage bar to cut to be cut into inclined-plane, 40 ~ 50 ° of angles, so that bury, top is cut and is cut into plane, plane is from reserved bud 1 ~ 2 centimetre of emerging (in practical operation, being generally rule of thumb carry out cutting in the lower end of a upper bud bud of reserved bud of emerging cutting).
Be 6 annual ~ October during rainy season described in step (1), temperature is 15 ~ 30 DEG C, and rainfall is more than 500mm, and the whole nation is local different, and rainy season is different, and implantation time is also different.
