Description
Technical field
The present invention relates to technical field of plant cultivation, more particularly to a kind of cultivation side of red purple leaf crape myrtle nursery stock
Method.
Background technology
Crape myrtle, also known as crape myrtle, cherry-apple tree, itch tree, it is native to China, belong to Lythraceae Lagerstroemia.Recorded according to history records
The history of existing 1500, is China's summer important flower trees, and the florescence is longer, and pattern is gorgeous.Crape myrtle is in gardens construction
In have extensive a purposes and vast potential for future development, Chang Zhi in building, in courtyard, Chi Pan, river bank, lawn surrounding and park
Path both sides；Now be widely used in shade tree, urban road lace in, or as bonsai production.Plant form is generally using only
Dry, Cong Gan and short dry reasonably combined, brings out the best in each other, to reach optimum efficiency.Crape myrtle has stronger absorption pernicious gas and suction
The effect of stagnant dust, particularly to sulfur dioxide, the better resistance of hydrogen fluoride and chlorine, according to surveying and determination every kilogram of crape myrtle cured leaf can inhale
Receive 10 grams or so of sulphur and keep growth and development good, at away from pollution sources 200-250m, every square of m blade can absorb and retain dust
4.42 grams, thus can be using crape myrtle as atmosphere pollution area Greeing species.Crape myrtle can produce volatility oils, to diphtheria bacterium,
The pathogens such as dysentery bacillus have obvious bactericidal effect.Therefore plantation crape myrtle can not only beautify the environment, moreover it is possible to prevent that air is dirty
Contaminate
It likes warming shed method to red purple leaf crape myrtle, and light, slightly shade tolerant, manurial-philous, saline-alkali tolerant, like deep fertile chiltern earth especially
Soil, it is also drought-resistant quite in the ground of slightly moisture, avoid flood, avoid and plant in the high low humidity place of level of ground water, and energy cold-resistant, sprout tillers
Property strong, wind resistance, high aphids resistance, highly resistance coal ash it is sick, adaptable, tender leaf aubergine, the black purple of mature leaf, spring, summer, Qiu Sanji
Ripe leaf color keep that black purple is constant, and red purple leaf crape myrtle also has stronger contamination resistance, to sulfur dioxide, hydrogen fluoride
And the better resistance of chlorine.Sulphur 10g, and well-grown are absorbed per blade, also there is the ability for absorbing and retaining dust, per 1m2Blade
Dust 4.2g can be absorbed and retain.Relevant expert is organized to Hu'nan Prov. Academy of Forest-Sciences's selection and breeding on July 30th, 2015, the Hunan Forest Room
U.S.'s purple leaf crape myrtle series new varieties have carried out in-process review, and opinion is vouched at the scene that expert has adopted the project unanimously, wherein
Including red purple leaf crape myrtle, these kinds are that Ji Guan flowers, sight leaf from U.S.'s introducing breeding out are excellent in a sports lottery ticket leaf crape myrtle
New varieties, landscape value are high.The cultivation technique of pellet purple leaf crape myrtle is immature at present, the red purple leaf crape myrtle nursery stock cultivated
Survival rate is not high, and the service life is shorter.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of cultivation side of red purple leaf crape myrtle nursery stock
Method, the survival rate of nursery stock is high, and the speed of growth of nursery stock increases, beneficial to the plant of large area.
The present invention is achieved by the following technical solutions：A kind of breeding method of pellet purple leaf crape myrtle nursery stock, including such as
Lower step：
(1), seed disinfection：
Full, flawless, not lopsided red purple leaf crape myrtle seed is chosen, is carried out disinfection processing with thimerosal, during processing
Between for 25-33 it is small when；
(2), site preparation：Select it is loose it is fertile, have abundant water resources, nursery is made in the place that irrigation and drainage are good, nursery is ploughed deeply before the winter is entered
30-35cm, farm manure 30-45t/m is applied with reference to site preparation2, calcium magnesium phosphate 3t/m2, the month in coming year 2-3, carefully ploughs soil, reaches soil
Soft, particle is tiny and the native abundance of suede, and a plurality of parallel furrow, furrow wide 150cm, high 20cm are built in Tanaka；
(3), seed treatment：7 days before sowing, with 0.2% potassium permanganate soaking disinfection 10-20h, after rinsed well with clear water
After be put into 50~55 DEG C of warm water immersion 24 it is small when, before seed buries, first soaked 3-5 minute with the gibberellin of 420mg/L, rear use
Baume 3-4 degree lime sulfur sprays seed；
(4), sow：Water before sowing to the wide furrow put in order, the yellow soil of auxiliary one layer of 3cm is added on wide furrow, after
Seed is uniformly sowed, 2-3 are spread every 3-4cm, after broadcasting gently spill last layer plant ash, then spill last layer suede soil, then add
Rice straw mulching, the thickness of plant ash is 0.2mm, and the thickness of suede soil is 1mm；
(5), frame canopy is with removing canopy：After seed finishes, the hut of a height of 90cm is set up on wide furrow, covers plastic film；When
After temperature stabilization goes back up to 18 DEG C, rainy days is selected, you can remove canopy；
(6), seedling management：Water in time after emergence, keep ground moistening, seedling, which goes out, uses thereafter 0.1%-0.2% nitrogen phosphorus
K composite fertilizer solution presses nitrogen-phosphorus-potassium compound fertilizer 15-20g/m2Dosage top dressing 2-5 times；
(7) prevention and control of plant diseases, pest control：The characteristic of the maximum preventing disease and pest of red purple leaf crape myrtle is exactly the performance of the high aphids resistance of tower,
Aphid mycoses hardly occur in whole growth course；Other pest and disease damages of red purple leaf crape myrtle are also less, and disease mainly has white
Powder disease, causes leaf abscission, with 800 times of liquid of ketone more than three or 0.3- when one layer of mould layer of white powder of blade back generation is serious when endangering
Lime sulfur spraying more than 0.5 Baume；
(8) garden is gone out：When seedling strain grows to 10-15cm, it is colonized, during field planting, the line space between seedling strain is maintained at
10cm。
Further, in step (3) seed be put into 50-55 DEG C of warm water immersion 24 it is small when.
Further, the thickness of plant ash is 0.2mm in step (4), and the thickness of suede soil is 1mm.
Further, the time of sowing is the annual 3-4 months in step (4).
The beneficial effects of the invention are as follows：A kind of breeding method of red purple leaf crape myrtle nursery stock of the present invention, utilizes the cultivation of science
Culture method, the survival rate of nursery stock is high, effectively shortens the growth cycle of red purple leaf crape myrtle sapling, and the speed of growth of nursery stock has carried
Height, beneficial to the plant of its large area；A kind of breeding method of red purple leaf crape myrtle nursery stock of the present invention, by the timely of powdery mildew
Treatment, so as to promote the growth of red purple leaf crape myrtle nursery stock, improves the survival rate of nursery stock.
