Abstract

The present invention discloses a breeding method of serenoa serulata. Said method includes the following several steps: selecting seed, seed treatment before sowing, soil treatment, seed treatment after sowing and transplanting germinated seed. Said method can make germination percentage of serenoa serulata seed be up to above 90%, and makes the percentage of success of seedlings also be up to above 96%.

Description

The breeding method of a kind of sabal

One, technical field

The present invention relates to the breeding method of a kind of sabal, belong to field of plant variety breeding technology, be exclusively used in the seed selection sabal.

Two, background technology

Sabal (Serenoa repens (bartram) small) formal name used at school is " sabal ", belongs to Palmae evergreen shrubs plant, and 2 to 3 meters of plant heights are because of the leaf margin indentation is gained the name; Main product is in southeastern US, promptly from the South Carolina to Mississippi downstate and Louisiana, the torrid zone and sandy soil Plain, strand, subtropics until the Florida State and the Gulf of Mexico.The flower of sabal is a kind of important honey source, stem can be used to extract tannic acid, sabal can also be as the ornamenter of environment, but the dry fruit hyoscine of sabal maturation, be rich in various fatty acid and volatile oil in its fruit, the extract of saw palmetto berry is divided into " sabal oil " and " sabal medicinal extract " two kinds, and they are natural hypertrophy of the prostate Remedies evident in efficacy; No matter sabal oil or medicinal extract were best-selling product on the international market in recent years.Sales volume U.S. sabal last year has entered preceding 3 (being only second to genseng, ginkgo) on the natural drug billboard.At least existing in the international market one, 200 kind of sabal class BPH Remedies.Several years ago, the sabal preparation of German drugmaker production has been squeezed into China market as " Bao Lvzhi " with " anti-prostatitis ".This shows that sabal has the bigger economic worth and the ecological value.According to relevant expert investigation, China still finds no the sabal resource up to now, can only be from overseas introduction.Sabal mainly breeds by seed, external traditional seeding method be broadcast, speed is fast, the saving of labor, quantity is comparatively convenient for a long time, but germination rate and transplanting survival rate are lower; It is difficult to germinate behind the planting seed, and germinating time is longer, and emerging irregular is its characteristics, and environment is also very big to its influence, and this is the difficult point in introducing a fine variety.

Three, summary of the invention

The present invention with the seed of sabal with the sterilization 30～35 minutes that carries out disinfection of 250～300 times of liquid of powder of carbendazim of 50%, clean with flushing with clean water then; Soaked 24 hours in 35 ℃ of constant temperature with the 250-500ppm naa again, after drying with the clear water edulcoration, broadcast in the penetrating sowing media of preserving moisture that river sand, coconut palm chaff and a small amount of loess is mixed with by a certain percentage and cultivate (matrix will with 0.5% liquor potassic permanganate disinfection).The about deeply 5cm of seed bed, between 1.5～2.5cm of seed bed, every intergranular is every 2～3cm with the seed program request, and hilum covers the composite soil of one deck fine sand and the fertilizer that becomes thoroughly decomposed down again after finishing kind, and thickness is about 2cm.Spread the rice hulls of one deck cleaning on the bed surface, broadcast the back and irritate once permeable.Accept sunlight daytime, trickle 3 times covers the hay insulation (reducing temperature difference luffing) about 10cm night, can make bed temperature Bao Te between 28～30 ℃.Regularly water later on, after seed sprouting, often spray water to the blade face.When treating that seedling grows 1～2 leaf, impose small amount of liquid fertilizer, to promote growth.When seedling grows to when 1～4 true leaf is arranged, be transplanted in the dark container of 25cm, basal part of stem is exposed native face, as run into sunburst, cover 50%～60% sunshade net.

The objective of the invention is, the breeding method of a kind of sabal is provided, the sowing pre-treatment of the seed selection of this method by sabal, seed, the processing of matrix soil, after planting handle and seed sprouting after transplanting, make the sabal seed send out the tooth rate and seedling percent significantly improves, for China introduces this kind and implant mass provides good method, avoided main later on this situation of import that relies on of saw palmetto berry.

With respect to prior art, the present invention has following characteristics: soak seed with the 250-500ppm naa, guarantee that moisture content enters in the seed smoothly, and to the protective effect of seed tool, guaranteed that seed germination rate is more than 90%.The matrix of using river sand, coconut palm chaff and loess to be mixed with, the composite soil of upper berth fine sand and fertilizer and rice hulls and hay, play preserve moisture, insulation, nutrition really, seed, the easier germinating growth of seedling, seedling percent also reaches more than 96%.

Specific embodiment 1:

When saw palmetto fruit is ripe, selects no damage by disease and insect, the maternal plant of the stalwartness of growing gathers, and selects seed full and the tool bright-colored, removal pericarp and pulp.Seed is put into container, account for 1/3～2/3, filled with water is stirred and after several minutes the seed of swimming is all removed, and the seed of heavy water is used for sowing.250～300 times of liquid of powder of carbendazim with 50% carried out disinfection sterilization after 30～35 minutes, and are clean with flushing with clean water; In 35 ℃ of thermostatted waters, soak after 24 hours with the 250-500ppm naa again, dry with the clear water edulcoration, be sowed in the penetrating sowing media of preserving moisture that river sand, coconut palm chaff and a small amount of loess is mixed with by a certain percentage (matrix will with 0.5% liquor potassic permanganate disinfection).Seed bed leveling earlier, about deeply 5cm, between 1.5～2.5cm of seed bed, every intergranular is every 2～3cm with the seed program request, and hilum covers the composite soil of one deck fine sand and the fertilizer that becomes thoroughly decomposed down again after finishing kind, and thickness is about 2cm.Spread the rice hulls of one deck cleaning on the bed surface, will irritate once permeable after broadcasting.Accept sunlight daytime, trickle 3 times covers the hay insulation (reducing temperature difference luffing) about 10cm night, has so just had the loose advantage of breathing freely and being easy to heat conduction, can make bed temperature Bao Te between 28～30 ℃.Regularly water later on, after seed sprouting, often spray water to the blade face.When treating that seedling grows 1～2 leaf, impose small amount of liquid fertilizer, to promote growth.When seedling grows to when 1～4 true leaf is arranged, to be transplanted in the dark container of 25cm, the transplanting survival rate of seedling is higher during wherein with 1 leaf.Grasp the depth of planting when planting, basal part of stem should be exposed native face, planting can influence its growth too deeply, as runs into sunburst, needs to cover 50%～60% sunshade net.

Claims
