A problem that paulownia seedling nursery via root burying occupies large space can be solved by the use of the container seedling nursing method; seedling nursing period can be shortened; and paulownia seedling nursery speed and rate can be improved.
Description
Technical field
The present invention relates to a kind of paulownia and bury root seedling-cultivating method, particularly Light media buries the container seedling culture method that root cultivates Paulownia seedling, and it is the optimization of paulownia being buried to root seedling growing process, thus minimizing paulownia bury a large amount of land occupation of root nursery, shorten growing-seedling period, improve paulownia nursery speed and efficiency.
Background technology
Paulownia are the famous and distinctive fast-growing indigenous tree speciess of China, and paulownia growth is very fast, are one of three large commerical tree species of most fast-growing in the world, in China's timber forest construction and ecological environmental protection, play irreplaceable effect.In recent years, China's Eco-environmental Forestry is fast-developing, and paulownia afforestation area constantly expands, and Paulownia seedling imbalance between supply and demand day is aobvious outstanding, how to accelerate the cultivation in paulownia breeding strong sprout, meets the need of market and become a problem demanding prompt solution.
Paulownia nursery mainly contains seeding and seedling raising and buries the methods such as root nursery, and paulownia seeding growing seedlings method produces upper seldom employing, mainly to bury root nursery.And traditional root nursery of burying is all adopt field seedling raising mode, take a large amount of soil, growing-seedling period is long and efficiency is low, is difficult to meet the needs of market to nursery stock.Meanwhile, field seedling raising is easily subject to infecting of nursery lot soil damage by disease and insect, forms seedling in spite of illness, causes potential threat to the Forest Cultivation of paulownia.Therefore, introduce in the cultivation of Paulownia seedling by the plastic tunnel of advanced person, Light media Container nursery technique, the technique for quickly cultivating solving paulownia breedings strong sprout is technical problem important during paulownia produce.
Summary of the invention
In order to overcome the deficiency of prior art problem, the invention provides a kind of Light media and burying root and cultivate the container seedling culture method of Paulownia seedling, bury root nursery floor space for paulownia large, growing-seedling period is long, speed is slow, and inefficient outstanding problem, works out a kind of method accelerating nursery.The method introduces in the cultivation of Paulownia seedling by the plastic tunnel of advanced person, Light media Container nursery technique, forms the technique for quickly cultivating in paulownia breedings strong sprout, for the quickly breeding in paulownia breeding strong sprout provides an effective way.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of Light media buries the container seedling culture method that root cultivates Paulownia seedling, comprises the following steps:
1) matrix select, proportioning and process
Light media coconut palm chaff, yellow soil, peat soil, mud are smashed respectively, Homogeneous phase mixing by a certain percentage, trickle is to moisture content 40 ~ 50%, and then loading specification is in the nutrition cup of 18cm × 16cm, and dress is real in rim of a cup 0.5 ~ 1cm place, neatly puts on the elevated bed in plastic tunnel for subsequent use;
2) root collection is planted
Select pure, the well-grown of kind, get root without the paulownia treelet of life in 0.5 ~ 2.5 year of damage by disease and insect, kind root diameter 0.8 ~ 3cm, after kind root digs out, be first placed in ventilating and cooling place 1 day, dry in the air unnecessary moisture, buries root in time;
3) root process and classification is planted
The kind root preparing nursery is cut into the long root segment of 6 ~ 7cm, clip wants level and smooth, then carries out classification by 0.8 ~ 1.5cm, 1.5 ~ 2.5cm, 2.5 ~ 3.0cm, buries the front root-growing agent process lower end clip of root;
4) root is buried
In nutrition cup, dig a vesicle by the length of kind of root and diameter, kind of a root is kept flat or puts upward for root polarity upper end, then cover 2 ~ 3cm by tight by matrix, make matrix and plant root close contact, after burying root, wanting timely trickle, keeping matrix moistening;
5) nursery stock management
According to seedling growth needs, regulate intensity of illumination, the temperature and humidity in canopy by shade net, spray equipment and ventilation equipment, strengthen water and fertilizer management, in good time prevention and elimination of disease and pests;
6) hardening and outplanting
When seedling growth to 25 ~ 28cm is high, seedling sorting to be moved on lower frame hardening bed hardening 10 ~ 15 days, and period suitably controls liquid manure, promotes nursery stock lignification, outplanting afforestation in rainy season.
Step 1) described in Light media coconut palm chaff, yellow soil, peat soil, mud fill cup after referring to and selecting Light media coconut palm chaff to mix by the ratio uniform of 7:3 with yellow soil; Or in coconut palm chaff: yellow soil: peat soil: the ratio of mud=7:1:1:1 mixes rear dress cup, carries out nutrition cup nursery.
Step 3) described in bury before root and refer to that by concentration be the methyl α-naphthyl acetate of 100 ~ 1000mg/kg with root-growing agent process lower end clip, or be the ABT1 root-inducing powder of 50 ~ 1500mg/kg by concentration, soak time 1 ~ 8 minute, soaking depth is root polarity lower end 2.5 ~ 4.0cm, imbeds Medium Culture after airing liquid.
Step 4) described in bury after root and want timely trickle, keep water content of substrate rate between 40 ~ 60%.
Step 5) described according to seedling growth needs, refer to that nursery in 1 ~ February is without the need to sheltering from heat or light by the intensity of illumination in shade net, spray equipment and ventilation equipment adjustment booth, temperature and humidity, nursery in 7 ~ August shade density is 35 ~ 70%, shelter from heat or light duration 6 ~ 7 hours, temperature controls between 18 ~ 38 DEG C, and humid control is between 60 ~ 80%.
Step 6) described seedling sorting is moved to hardening on lower frame hardening bed and refers to that period is except experiencing natural light irradiation, not applying fertilizer and reduce except trickle, also will wipe out unnecessary rudiment and growing way is weak and bending seedling, every nutrition cup only retains 1 strain healthy seedling.
The invention has the beneficial effects as follows:
1, an effective technological approaches can be provided for the quickly breeding in paulownia breeding strong sprout by implementing the present invention.
2, by regulating ventilation and the humidity of intensity of illumination, temperature, humidity and matrix in plastic tunnel, be conducive to improving kind of a root germination rate, promote growth of seedling, seedling-growing time shortens, and planting percent and emergence rate increase.Effectively overcome the climatic factor of Various Seasonal etc. to the impact of nursery and restriction, south China throughout the year all can with this method nursery simultaneously.
3, by elevated bed nursery, lower frame bed hardening, effectively isolation nursery stock contacts with the direct of soil-borne disease insect pest in nursery lot, reduces the generation of damage by disease and insect.
4, can effectively utilize land resources, unit are is produced seedling amount and is greatly improved.Light media nutrition cup nursery stock also facilitates seedling sorting, afforestation of transporting and go up a hill.
