Abstract
The invention provides a cuttage method for gingkoes. The cuttage method includes the following steps: 1, collecting seed branches, wherein from the late May to the mid-June, the seed branches are collected when newly-grown branches of the gingkoes are half lignified; 2, processing the seed branches, wherein the seed branches are placed into fresh water for moisture preserving, two or three leaves of each seed branch are kept, the length of each seed branch is limited to range from 10 cm to 16 cm, the distance between upper sheared wounds and buds of the seed branches ranges from 0.6 cm to 1 cm, the seed branches are bound, the lower ends of the seed branches in each bundle are soaked into a rooting powder solution for two hours, and the seed branches are taken out for preparing; 3, preparing a cuttage bed, wherein the cuttage bed is made in a field exposed to the sun, river sand with the thickness 30 cm is laid on the bed surface of the cuttage bed, leveled and then thoroughly watered, the river sand is sprayed with disinfectant while the river sand is overturned, the cuttage bed is covered with a plastic film for nine days, the plastic film is removed at the time four days before the cuttage bed is used, and the river sand is overturned, ventilated, aired and then leveled; 4, carrying out cuttage. By means of the cuttage method, grafted seedlings are high in survival rate, the seedling growing cost is reduced, and the market requirement can be met.
Description
Technical field
The present invention relates to the cottage method of a kind of ginkgo.
Background technology
Ginkgo is the rare seeds of few survivors in Mesozoic Era, and ginkgo is fallen leaves megaphanerophyte, and the diameter of a cross-section of a tree trunk 1.3 meters above the ground can reach 4 meters, and treelet bark is closely level and smooth, light grey, the skin taupe of large tree, and irregular lobe is coarse; There are long shoot and poky distance shape brachyplast.Be born in the natural forest in height above sea level 500-1000 rice, acidity (pH value 5 ~ 5.5) yellow earth, the good area of draining, normal coniferous and deciduous tree species is mixed with cryptomeria, Chinese torreya, tupelo etc. gives birth to, and grows vigorous.
Ginkgo is light demanding tree, happiness suitably moistening and well-drained deep loam, is suitable for growth in the monsoon region, subtropics of hydrothermal condition comparative superiority.All can well-grown in acid soil (pH4.5), calcareous soil (pH8.0), and with neutral or micro-sour soil optimum, the ground of not resistance to ponding, comparatively can be drought-enduring, singly at the ground undergrowth of too dry place and many tors slope or low humidity.Primary growth is comparatively slow, covers tiller strong.Female plant starts solid in general about 20 years, and the large tree of life in 500 years still can be normally solid.General late March to early April sprouts Zhan Ye, and early April bloomed to the middle ten days, and late September, late October fell leaves to November to early October seed maturity.
Ginkgo propagation by grafiting Measures compare is loaded down with trivial details, and graft survival rate is not good, and therefore grafting method can not meet the demand in market.
Summary of the invention
The technical problem to be solved in the present invention is to provide the cottage method of a kind of ginkgo, and plant percent is higher, reduces seedling cost, can meet the demand in market.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A cottage method for ginkgo, comprises the following steps:
(1) seed collecting bar: between late May to mid-June, adopts bar of sowing during ginkgo new life branch semi-lignified;
(2) bar process is planted: kind of a bar is put into clear water moisturizing, every bar kind bar retains 2 ~ 3 leaves, the length of every bar kind bar is restricted to 2 ~ 5cm, distance between upper clip and the bud of planting bar is 0.6 ~ 1cm, and clip base portion is truncation shape, and lower clip is horse-hof shape, kind of a bar is tied up, often tie 50 ~ 70 kind bars, the lower end of often tying kind of bar to be soaked in rooting powder solution 2 hours, to take out for subsequent use;
(3) cutting bed prepares: make cutting bed on the sunny side, the thick river sand of 30cm is spread at the bed surface of cutting bed, water permeable after leveling, river sand is sprayed with thimerosal, stir river sand simultaneously, with covered rearing with plastic film cutting bed 9 days, use when first 4 days at cutting bed and open plastic film, stir river sand, smooth after ventilation airing;
(4) cuttage: the iron wire consistent with planting bar by thickness punches on cutting bed, seeding row spacing is 6cm × 5cm, the kind bar cuttage handled well is entered in the hole on cutting bed, the cuttage degree of depth is 2 ~ 5cm, cutting bed is sprayed once with clear water after cuttage is complete, use covered rearing with plastic film cutting bed, checked a cutting bed every 4 days and spray clear water, cutting bed is sprayed once with bactericide every 12 days, temperature automatically controlled moisture control device is used to carry out temperature humidity management, progressively remove plastic film, hardening after 60 days, transplant.
Preferably, in step of the present invention (2), rooting powder solution is GGR solution.
Preferably, in step of the present invention (3), the length of cutting bed is 4 ~ 6m, and width is 2 ~ 3m, and the degree of depth is 45cm.
Preferably, in step of the present invention (3), thimerosal to be concentration be 2% formalin solution.
Preferably, in step of the present invention (4), bactericide is the thiophanate methyl solution of 2000 times.
Compared with prior art, the present invention has following beneficial effect:
The lower clip of horse-hof shape is conducive to cuttage success and more easily forms callus, root-inducing powder effectively can improve the survival rate of kind of bar rooting rate and nursery stock, river sand layer in cutting bed and can close contact between cuttage nursery stock, be of value to kind of a bar to take root, temperature automatically controlled moisture control device regulable control temperature humidity can reach the scope of applicable seedling growth in time, therefore the cottage method that the present invention adopts can successful reproduction ginkgo, survival rate can reach more than 82%, effectively reduce seedling cost, meet the demand in market.
