Technical field
The present invention relates to a kind of phoenix pellet seed seedling-raising methods, belong to the technical field that plant seedling is bred.
Background technology
Tree peony (Paeonia suffruticosa Andr.) is Ranunculaceae (Ranunculaceae) Paeonia (Paeonia
L.) Section Moutan (Sect.Moutan DC.) machaka is that China is peculiar.Tree peony is removed with high ornamental value and medicinal
Value is outer, and the seed oil content of some Varieties of Peony is higher, can be developed and utilized as woody oleiferous plants resource, i.e., oily with male
It is red.At present, the oil of China's popularity plantation is mainly phoenix pellet tree peony (Paeonia ostii T.Hong et with Varieties of Peony
) and Paeonia papaveracea (Paeonia rockii T.Hong＆J.J.Li) J.X.Zhang.In Shandong Province of Zhu Zai areas, phoenix pellet tree peony accounts for
More than 95%.Unsaturated fatty acid content is up to 90% in peony seed oil, and wherein alpha-linolenic acid content is up to 42%.From 2011
Year, since peony seed oil is defined as new resource food, oil is constantly expanded with the cultivated area of tree peony, and there is kind in national each province and city
Report, seedling rush of demand are planted, the peony seeds of various regions harvesting are mainly used for cultivating seedling.
At present, the phoenix pellet seed seedling-raising time, late September terminated generally since late August, mainly used drill seeding nursery,
Phoenix pellet seed dosage is 100-150kg per acre.It is estimated by mass of 1000 kernel, phoenix pellet seed dosage is 35.7 ten thousand -53.6 ten thousand per acre,
Can 7.5 ten thousand plants or so of output seedling, planting percent is only 13.99%-21.01%.Existing oil tree peony seedling-raising technique, seedling go out
Native time phase difference is larger, and once sowing will cause the sturdy degree of seedling to differ across 2 fraction of the year, 3 emergences.It is easily miscellaneous after coming up
Grass covering, need to remove weeds in time, add labour's expenditure.The drill seeding nursery area that occupies cultivated land is big, and seedling is generally in 2-3
It is sold after year, land utilization ratio is low.In view of the above-mentioned problems, finding, a kind of peony seeds planting percent is high, at low cost, seedling quality is high
Method for culturing seedlings is very necessary.
Patent CN201010569561.5 (entitled " a kind of Paeonia suffruticosa seed container for plant growth and quickly educating using the container
Seedling-growing method ") describe the method that Paeonia suffruticosa seed uses container fast seedling growing.Seed used in this method is Paeonia delavayi seed, used
Container is biological degradability non-woven fabrics Seedling bag.The processing method of Paeonia suffruticosa seed can be summarized as：Potassium permanganate seed soaking-clear water punching
Wash-Soaking in hot water-normal-temperature water is soaked seed-take root amidin seed soaking.Mode of sowing and seedling propagation is：Seed after seed soaking is directly seeded in
