The invention has simple process, convenient operation, is able to effectively improve the germination speed, germination rate and uniformity for the Syagrus romanzoffiana seeds, shortens the seedling cultivation time, hoists the seedling quality and provides a rapid means for merchandizing the seedling.
Description
Technical field
The present invention relates to the vernalization and the seedling-cultivating method of a kind of queen certain herbaceous plants with big flowers (Arecastrum romanzoffianum Becc.) seed, belong to the technical field of plant seedling breeding.
Technical background
The queen certain herbaceous plants with big flowers belongs to the Palmae Livistona, originates in Brazil, Argentina, Bolivia.Trunk is tall and straight, and atop the blade of clustering is gained the name because of exactly liking the superoccipital hat decorations of emperor just like loose feather, is the typical tropical palm plant, can do southern flower garden and view and admire tree or street tree, also can make seashore greening material.Last century, the queen certain herbaceous plants with big flowers was introduced indivedual areas of China and correlative study mechanism as garden plants, popularized in China's south afforestation as green plants gradually and utilized.
Queen certain herbaceous plants with big flowers happiness is warm, moistening, on the sunny side and the environment that ventilates, ability-2 ℃ low temperature.Require fertile and damp soil.Stronger wind resistance power is arranged, the ability alkaline tide, not drought-resistant.Conventional method adopts seed seedling-raising, and it is solid that general 10 years livings trees can begin, and bloom 6～July, and September is really ripe.Pericarp tool cellulosic, seed grain is big, and thousand kernel weight reaches 2700 grams, and 5～8 months resting stage is arranged, and the dormancy degree of depth between individuality is also uneven, sowing in May in next year, it is extremely irregular to germinate, the summer high temperature phase, sustainable about 100 days of germination front and back, germination rate is about 60%.Seed is gone up basin from seed collection to emerging and is needed the time more than 2 years.The limitation and the drawback of this kind method show as: it is irregular to germinate, and a maintenance time of growing seedlings is long; If the control of temperature and moisture will influence the embryo activity of seed accidentally during the vernalization; The stage of growing seedlings is subjected to the limitation of nature temperature and illumination condition bigger.
Summary of the invention
The objective of the invention is to provide a kind of vernalization and seedling-cultivating method of Syagrus romanzoffiana seeds at the deficiencies in the prior art, obtain good seed in a short time by rational vernalization and seedling-cultivating method, can guarantee that not only growth of seedling is good, more shorten vernalization and growing-seedling period, the double project seedling that is applicable to scientific research institution is equipped with and utilization is produced in the commercialization of afforestation enterprise.
The technical solution adopted in the present invention is:
A kind of Syagrus romanzoffiana seeds vernalization and seedling-cultivating method, its concrete steps are as follows:
1, seed collection and vernalization
Choose full, the strong Syagrus romanzoffiana seeds of gathering after annual September, soaked 10～15 days with clear water under air-proof condition, clear water did not have 5～10 centimetres in seed, and the exocarp for the treatment of seed rots after the deliquescing its removal is cleaned up; The seed that cleans up placed 0.05～1% liquor potassic permanganate soaked 30～50 minutes, clean up; Again Syagrus romanzoffiana seeds is immersed in 0.04%～0.1% the solution of zinc sulfate 24～48 hours, cleans up, stand-by.
2, prepare in the seedbed
Seedling medium is packed in ventilative, the permeable container, 1000～2000 times of thiophanate methyl solution of drenching, waiting to dry in the air gets final product to half-dried; Described seedling medium is by fertilizer, becomes thoroughly decomposed coconut palm chaff and particulate river sand by volume: fertilizer: the coconut palm chaff becomes thoroughly decomposed: particulate river sand=1～2: 1: 1 ratio is mixed; Described fertilizer is the animal wastes of becoming thoroughly decomposed; The described coconut palm chaff that becomes thoroughly decomposed is the coconut palm chaff that nature was placed 1～2 year.
3, sowing and seedling management
To be sprinkled upon uniformly through the Syagrus romanzoffiana seeds of vernalization on the seedbed, keeping the seed spacing is 2 centimetres, gently presses seed with plank, covers one deck fine sand again, and thickness is just to cover seed degree of being completely, the water of drenching; The seedbed is moved into management under the cool canopy, and trickle is 1～2 time weekly, keeps soil matrix moistening; After treating seed germination and exposing Shamian Island, keep in the cool canopy humidity 75～80%, between 25～32 ℃ of the temperature of shed, 3～5 months time.
4, transplant
Choose the packed nutrition soil of nutrition, the transplantation of seedlings that grows 2～3 leaves is gone in the nutritious bag, the water of drenching is put into the cool canopy management; Keep nutrition soil moistening, can be used for acclimatization and transplants until the cultivation nursery stock.Described nutrition soil is by fertilizer, coconut palm chaff and particulate river sand by volume: fertilizer: the coconut palm chaff becomes thoroughly decomposed: particulate river sand=2～3: 1: 1 ratio is mixed.Described fertilizer is the animal wastes of becoming thoroughly decomposed.
Process of the present invention is simple, and is easy to operate, can improve Syagrus romanzoffiana seeds effectively and sprout speed, germination rate and regularity, shortens seedling raise period, promotes the seedling quality, for the production of commercialization queen certain herbaceous plants with big flowers seedling provides a kind of method efficiently.
Concrete embodiment
The invention will be further described to adopt non-limiting embodiment below.
Embodiment one
