Abstract
The invention discloses a kind of method for culturing seedlings in Qinggang, first select the raw healthy and strong elite stand of 20-30 to collect seed, can acquire when kind of a skin switchs to brown by cyan, the seed after harvesting replaces storage with wet sand by dry sand indoors；The seed for further taking out storage is eluted with water, and picks out full seed water logging kind, carbendazim disinfection, and disinfection is eluted with water after taking out, and carries out vernalization；Then loosing soil, deep place are selected, after deep ploughing, base manure is applied, is sowed with drilling method, fine earth covering after having sowed, then straw is covered, it waters immediately after plantation；After coming up, the straw of covering is removed, carries out shading management, and imposes 6-8kg/ mus of urea, is watered in due course, ground moistening is kept.The present invention provides the raising technologies of Qinggang high quality seedling, and Qinggang nursery stock surrival rate of afforestation can be improved, and to the Tree Species Resources and forest structure for developing and using Qinggang germ plasm resource, adjusting Hills, are of great significance.
Description
Technical field
The invention belongs to breeding plant technical fields, and in particular to a kind of method for culturing seedlings in Qinggang.
Background technique
Qinggang is the tertiary tree species in Fagaceae Qinggang.Aiphyllium, high up to 20 meters, the diameter of a cross-section of a tree trunk 1.3 meters above the ground is up to 1 meter, the flat wide ellipse of tree crown
Shape, bark dark gray or filbert.It is distributed on the south the Qinling Mountains to south China, Xi Daxizang.Qinggang often with China fir, sweetgum, moso bamboo, hook
The mixed generation woods such as chestnut, Phoebe bournei, Chinese ilex, Schima superba.Qinggang adaptability is stronger, and acidity can be grown to alkaline basement rock, in limestone
Ground can form single dominantcommunity, and natural regeneration power is strong, grow middling speed.Qinggang is relatively more cold-resistant, is resistant to extreme low temperature, and resistance to shady and resistance to
Barren, deep-rootedness, the system of taproot, resistance to drying, to sprout pressure strong, can Sprout reproduction.
Qinggang is widely used, is important Landscape Trees, also can be used as fire prevention, windbreak tree species, is also important
Economy, commerical tree species.Due to Qinggang impoverishment tolerant, calcareous soil is liked, the timber in Qinggang is hard, and toughness is high, and drying shrinkage is larger, corrosion resistant
Erosion, can do furniture, floor etc., right and wrong, can up to 60%-70% often with the commerical tree species for having development prospect, kernel starchness
Food, the also extractable tannin extract of bark, therefore be extraordinary multipurpose tree species, economic value is big, due to Qinggang well developed root system, side shoot
More, the features such as biomass is big, Qinggang are able to maintain water and soil, improve southern area of China is also widely used as fire wood, water protects tree species
Soil fertility has important ecological benefits.
Existing Qinggang germplasm resource is mostly sporadicly distributed in masson pine, China fir coniferous forest and other scondary forests, face
Face resource exhaustion, seldom to its scale breeding stock growing, so that its seedling breeding technology lagging in development.
Summary of the invention
The purpose of the present invention is in view of the above deficiencies, providing a kind of method for culturing seedlings in Qinggang, it is excellent that this method provides Qinggang
The Cultivating techniques of matter seedling, can be improved the surrival rate of afforestation, to development and utilization Qinggang germ plasm resource, develop precious evergreen species, adjust
The Tree Species Resources and forest structure of whole Hills, are of great significance.
A kind of method for culturing seedlings in Qinggang, comprising the following steps:
Step 1, collect seed and seed treatment: the raw tree-like end selection 20-30 is straight, no disease and pests harm healthy and strong elite stand seed collecting, when
Kind skin can acquire when switching to brown by cyan, and the seed after harvesting replaces storage with wet sand by dry sand indoors；
Step 2, Seeds preprocess: the seed for taking out storage is eluted with water, and picks out full seed water logging kind, carbendazim
Disinfection, is eluted with water after taking-up, carries out vernalization；
Step 3, seeding and seedling raising: selection loosing soil, deep place after deep ploughing, apply base manure and add desinsection, fungicide,
Make bed by the wide 1.2m in seedbed, furrow width 30cm, depth 5-6cm site preparation, every row 12 to 15, line-spacing 25-30cm, strain are pressed with drilling method
It is sowed away from 5-8cm, fine earth covering after having sowed, then covers straw, watered immediately after plantation；After coming up, removal is covered
The straw of lid carries out shading management, and imposes 6-8kg/ mus of urea, waters in due course, keeps ground moistening.
Preferably, in step 1 do sand replace with wet sand storage be first by seed with do sand by volume 1: 2 mix after in 5-
10 DEG C storage 1-2 months, after taking-up again with thin wet sand by volume 1: 2 mix after at 5-10 DEG C of storage 2-3 a month；During storage
Thin wet sand need to keep wet.
Preferably, it is specifically first used soaked in cold water 5-7 days in step 2 with water logging kind, carbendazim disinfection, uses carbendazim thereafter
Concentration 50-80 μ g/mL, to seed carry out sterilizing.
Preferably, vernalization is that water spray 10-20% is placed in closing indoor environment after cleaning the seed after seed soaking in step 2,
It is placed 4-6 days under the conditions of 10-20 DEG C, the too low covering film thermal insulating of temperature, the excessively high windowing ventilation of temperature.
Preferably, base manure adds desinsection, fungicide by carbendazim 2.5kg, Furadan 5kg and commercially available compound fertilizer in step 3
50kg mixing composition, dosage is carbendazim 2.5kg, Furadan 5kg, commercially available compound fertilizer 50kg per acre.
Preferably, Furadan combination urea top dressing can be used in step 3, to reduce pest and disease damage.
Preferably, the seed soaked seed in step 2 need to be first washed with water with ultrasonic treatment and carry out vernalization only, and ultrasound condition is frequency
Rate 350-360kHz, 10-20min.
Method for culturing seedlings of the invention replaces storage with wet sand using Indoor Dry sand to collected bitter sweet oak seed, effectively protects
Hold seed vitality；Vernalization processing is carried out to bitter sweet oak seed before sowing, not only can effectively break the suspend mode of seed, improve the thin of seed
Cytoactive promotes the division and differentiation of cell, improves germination percentage and emergence rate, the nursery stock surrival rate of afforestation is improved, to development and utilization
Qinggang germ plasm resource, the Tree Species Resources and forest structure for adjusting Hills increase precious evergreen species and are of great significance.
