Description

The implantation methods of a kind of petunia
Technical field
The invention belongs to planting tree technical field, particularly relate to the implantation methods of petunia.
Background technology
Petunia Solanaceae, green winter Solanum.Also known as green winter eggplant.Perennial herb, the biennial cultivation of Chang Zuoyi, high 20-45 centimetres; Stem grows with crawling, and is had cement pubescence; The food value of leaf is soft, avette, Quan Yuan, alternate, and upper leaf is to life; Flower Dan Sheng, in funnel-form, double flower is spherical, grey, purple or various redness, and studs with its look limit, and very beautiful, April at florescence is to falling frost; Capsule; Seed is tiny.Be distributed in South America, nowadays various countries are widely popular.Plant height 40 ~ 60cm, complete stool has glandular hairs.Leaf alternate, upper leaf is closely to life, avette, Quan Yuan, nearly stockless.Corolla funnel-form, footpath 5 ~ 18cm, eaves portion 5 is blunt to be split, or has the types such as wrinkle folding, crimping, polyphyll.Pattern is very abundant, as white, red, purple, blue, yellow and embedding line, fringing etc.April at florescence, winter warm area is sustainable bloomed to the Frost's Descent.
Warm and the sun-drenched environment of petunia happiness.Not resistance to frost, Keep away from rain flood.Its growth thermophilic is 13 ~ 18 DEG C, and winter temperature is at 4 ~ 10 DEG C, and as lower than 4 DEG C, plant strain growth stops.Summer ability more than 35 DEG C high temperature.Summer grows the most productive period, needs adequate water, and especially in summer high temperature season, Ying Zao, evening water, and keeps basin soil moistening.But plum rain season, rainwater is many, and very unfavorable to petunia growth, basin soil is excessively wet, the easy excessive growth of cauline leaf, and florescence rainwater is many, flower fugitive color or rotten.If basin soil long-term ponding, then rotten death, so potted plant petunia should use loose fertile and well-drained sandy loam.
Belong to long-day plant, vegetative period requires sunny, under normal illumination condition, about needs about 100 days from sowing to blooming.Winter, when cultivating petunia in booth, under low temperature short-day condition, cauline leaf growth was very luxuriant, but it is very difficult to blossom, under entering the long-day, soon from cauline leaf top differentiation bud in spring.
Petunia likes the kind liked very much of flower person, but existing petunia planting technology is perfect not, does not have systematic flow process, causes the plantation of petunia cannot scale.
Summary of the invention
The present invention is exactly for the problems referred to above, provides a kind of implantation methods accelerating a kind of perfect petunia of petunia growth rate.
To achieve these goals, the present invention adopts following technical scheme.
An implantation methods for petunia, comprises the following steps.
One, seeding and seedling raising, petunia is field planting open country after latest frost, and can cultivate 6 ~ 8 large branches through about 90 days, the number of blade more than 50 pieces, some kinds reach and at least open the very large rice shoot of 1 flower.If in sowing in April, within more than 60 day, can bloom.Some Hybrids are during insemination and emergence, and the ability of anti-unsuitable environmental condition can not show a candle to conventional variety, therefore must note the control of environmental condition during sowing.Every square metre of seeding in nursery bed amount about 1.5 grams, as used expensive seed, is no more than 1.2 grams; Because seed is superfine little, broadcast again after seed should being mixed with the fine earth of 30 ~ 50 times or fine sand.Broadcast rear covering fine earth 0.2 centimetre, prevent from hanging dry kind of bud; Thin earthing is higher than not having the emergence rate of earthing.
Two, transplant, petunia petunia, throughout the year all can seeding and seedling raising under the protecting field condition of In Middle And Lower Reaches of Changjiang River, because general blossom-control technics is on May Day, National Day, so sowing time autumn sowing is in 10 ~ November, sows in spring in 6 ~ July; Install medium before sowing, water permeable, broadcast the moistening seed of rear thin spraying, seed can not cover any medium, otherwise can affect germination.Broadcast rear maintenance medium temperature 22 ~ 24 DEG C, within 4 ~ 7 days, emerge; Execute the nitrogen solution of 50 × 10-6 concentration after first pair of true leaf occurs, and note ventilating, seedling also can be shown in light gradually; When 2 ~ 3 pairs of true leaves appear in seedling, medium temperature can be reduced to 18 ~ 20 DEG C, every 7 ~ 10 days, executes the compound solution of 0.1% of 0.1% urea solution or N P and K 15-15-15; This stage must be noted ventilating, and prevents disease from producing, sprays tpn or thiophanate methyl 800 ~ 1000 times of liquid every about 1 week; When 3 pairs of true leaves appear in plant, the intact formation of root system, temperature, humidity, fertilising require the same, still will note ventilation, diseases prevention work.
Three, basin in transplanting, the seedling-cultivating tray nursery in 288 caves, autumn sowing directly moves into the nutritive cube of 13 centimetres of bores, the general nutritive cube only moving into 10 centimetres of bores of sowing in spring; Also first can be colonizated on seedbed, then move in nutritive cube; (1) Illumination adjusting; Petunia production in summer is more high temperature resistant, and general only in addition sunshade in several days, slow seedling after transplanting, all do not need sunshade in whole vegetative period; (2) temperature controls.Petunia is transplanted rear temperature and controls at about 20 DEG C, and not lower than 15 DEG C, too low can the postponement of temperature is bloomed, and does not even bloom.In actual production, what require bloom National Day will produce in booth, avoids affecting because temperature is low before National Day blooming; Requirement was bloomed on May Day, also can produce at open country, but must ensure that winter, frost did not directly drop on blade, otherwise blade there will be white dot, affects appreciation effect; In In Middle And Lower Reaches of Changjiang River, generally all adopt protecting field facility cultivation.
Four, cultivation management, waters not follow dryly all the time and does not water, water, the principle irrigated.Petunia production in summer potted flower, early stage is answered frequently thin fertilizer in seedling growth, fertilizer selects nitrogen, potassium content high, phosphorus is suitably on the low side, nitrogenous fertilizer can select urea, composite fertilizer then select nitrogen phosphoris and potassium fertilizer ratio be 15-15-15 or nitrogenous, potassium is high, concentration controls 0.1% ~ 0.2%, water soluble fertilizer generally selects 20-10-20 and 14-0-14 two kinds, concentration in 50 × 10-6 ~ 100 × 10-6.Winter production potted flower, at diligent sealing fertilizer in 3 ~ April, depending on growing state, suitable Nitrogen Top Dressing.General without pinching process during petunia produces, but need pinching once in summer.
Further, the pest control method of petunia is, the disease mainly seedling sudden fall ill of petunia, vegetative period stem rot; Major Pests has diamond-back moth, aphid, leaf roller etc., especially comparatively common in the production of flowers and plants on National Day; Occur that aphid generally can not spray with killing logvalue, easily cause poisoning, impact growth; Five, garden quality is gone out; The potted flower of winter production, adopts the nutritive cube of 12 centimetres of bores, and hat width is generally between 20 ~ 25 centimetres, and strain shape is neat, full, blooms consistent; The potted flower of production in summer, adopts the nutritive cube of 10 centimetres of bores, and hat width is generally at 15 ~ 18 centimetres; Petunia can be transported for long-distance.
Again further, the more resistance to pruning of petunia, if prune failure in first time, can prune once again, afterwards by changing basin, frequently thin fertilizer, maintenance be proper, does not generally affect quality, still can sell.
Beneficial effect of the present invention.
The present invention utilizes scientific and reasonable petunia implantation methods that the growth rate of petunia is accelerated, and extends the florescence of petunia, makes the beautiful in colour of petunia, more so beautiful that it excites men.And this implantation methods, easy to learn, be applicable to popularity.
