Description
Technical field
The present invention relates to the red seed seedling-raising method of a kind of phoenix, belong to the technical field of plant seedling breeding.
Background technology
Tree peony (PaeoniasuffruticosaAndr.) is Ranunculaceae (Ranunculaceae) Paeonia (PaeoniaL.) Section Moutan (Sect.MoutanDC.) machaka, for China is peculiar.Tree peony is except having high ornamental value and medical value, and the seed oil content of some Varieties of Peony is higher, and can be used as woody oleiferous plants resource and develop and utilize, namely tree peony used by oil.At present, the oil of China's popularity plantation is with the Varieties of Peony mainly red tree peony (PaeoniaostiiT.HongetJ.X.Zhang) of phoenix and Paeonia papaveracea (PaeoniarockiiT.Hong & J.J.Li).In Shandong Province of Zhu Zai district, the red tree peony of phoenix accounts for more than 95%.In peony seed oil, unsaturated fatty acid content is up to 90%, and wherein alpha-linolenic acid content is up to 42%.From 2011, since peony seed oil is defined as new resource food, oil constantly expands by the cultivated area of tree peony, and all there is plantation report in national each province and city, its seedling rush of demand, and the peony seeds gathered in various places is mainly used in cultivating seedling.
At present, the phoenix red seed seedling-raising time, late September terminated generally from late August, main employing drill seeding nursery, and every mu of red seed consumption of phoenix is 100-150kg.Estimated by thousand kernel weight, the red seed consumption of every mu of phoenix is 35.7 ten thousand-53.6 ten thousand, can about output seedling 7.5 ten thousand strain, and planting percent is only 13.99%-21.01%.Existing oil tree peony seedling growing process, the time phase difference that comes up is comparatively large, once sowing will across 2 fraction of the year emerge for 3 times, cause the sturdy degree varies of seedling.Easily covered by weeds after coming up, need weed a garden in time, add labour's expenditure.Drill seeding nursery occupies cultivated land area greatly, and seedling is generally sold after 2-3, and land utilization rate is low.For the problems referred to above, it is very necessary for finding the seedling-cultivating method that a kind of peony seeds planting percent is high, cost is low, seedling quality is high.
Patent CN201010569561.5 (name is called " fast seedling-cultivating method of a kind of Paeonia suffruticosa seed container for plant growth and this container of employing ") describes the method that Paeonia suffruticosa seed adopts container fast seedling growing.The method seed used is Paeonia delavayi seed, and container used is biological degradability non-woven fabrics Seedling bag.The processing method of Paeonia suffruticosa seed be can be summarized as: potassium permanganate seed soaking-clear water flushing-Soaking in hot water-normal-temperature water seed soaking-root-inducing powder aqueous solution seed soaking.Mode of sowing and seedling propagation is: the seed after seed soaking is directly seeded in and is equipped with in the non-woven fabrics Seedling bag of matrix, 3 every bag.In culture of rootage 8-12 week, low temperature treatment 6-12 week removes top-wall effect.This seedling-cultivating method is to the process of Paeonia suffruticosa seed too very complicated; Seed is directly seeded in matrix, and culture of rootage required time is long; Every bag of 3 seeds, during seedling plant division, root tied up in knots, easily hinders root.
Patent CN201510196728.0 (a kind of seedling-cultivating method of oil Paeonia suffruticosa seed) the biological degradability non-woven bag that have employed in above-mentioned patent carries out nursery to purple plague purpura seed.Its method is, seed collection and process: gather the fruit that kind of pod is buff, and deposit in shady and cool moist place, seed is deviate from naturally, and wet concentration is planted only.Seed storage: pure seed is sterilized, clear water cleans rear normal-temperature water seed soaking 10-12h, spreads shady and cool place to exosper and receives dry, preserve in the wet sand after place Min layers is placed on and disinfects, husky Tibetan 10-15d.Seedbed prepares: lime brick is built into, and fills fresh river sand.The seed plant growth regulator of seeding and seedling raising: Sha Zanghou soaks, and bar is sowed in the husky bed of sterile nursery, shelters from heat or light until seed germination.Move bag on bud: cotyledon is displayed for the first time, lifting moves to field planting in the non-woven bag that matrix is housed.Management after transplanting: the non-woven bag that bud seedling is housed is put neatly, and surrounding river sand encloses and blocks, and sunshade net shelters from heat or light, and seedling is sterilized after growing true leaf.In the method, fruit is placed in shady and cool moist place, slightly improper.The real moisture content of fresh kind under adopting is large, and in humidity place, pericarp and seed very easily go mouldy.Hide from seed sand and take root to seeding and seedling raising again to moving bag bud, finally arrive Field planting, plant need experience 2 transplantings, and not only operation is more loaded down with trivial details, also easily damages plant.
Be contained in polyethylene film container after annual oil is done root system pruning with tree peony seedling by patent CN201510705056.1 (a kind of oily container seedling culture method with tree peony and seedling medium) and cultivate.Plant finally arrives Field planting needs experience to transplant for 2 times equally.
Therefore, although the method introducing Paeonia suffruticosa seed nursery is at present more, in seed collection time, seed treatment, the aspects such as nursery operation and transplanting and management still have the space of improvement.
