Abstract

The invention belongs to the technical field of plant culture, and relates to a method for regulating the flowering period of calothea zebrina, 90 days before the expected flowering are taken as an induced flowering period, illumination time is kept for 10 hours every day in the induced flowering period, and the illumination intensity in the light period is kept between 15000lux and 20000lux, the dark period is 14 hours each day, and the calothea zebrina is uninterruptedly treated for 90 days; in addition, the calothea zebrina is irrigated with a mixed liquor composed of 7200 times of micronutrient fertilizer with the trade name of STEM and 1000 times of potassium dihydrogen phosphate with EC equal to 1.0-1.5 each week during the induced flowering period, the temperature is kept at 22-28 DEG C by day and 21-23 DEG C at night, and the humidity is always kept between 75% and 85%. The method can cause the calothea zebrina to flower out of season.

Description

A kind of Calathea zebrina florescence regulation and control method
Technical field
The present invention relates to a kind of plant cultivation technology; Florescence regulation technology particularly.
Background technology
Calathea leopardina has another name called the zebra arrowroot, and Latin Calathea Warscewiczii is Marantaceae Xiao Maranta plant.Calathea leopardina elliptic leaf shape, long 40～45cm, wide 25～27cm, the leaf back purple, blade face bottle green patch is inlayed, and daytime, blade was opened, and close up night, and the flower arrow is extracted floral white out in leafage.
The Maranta plant propagation is many to carry out in conjunction with turning over basin in 4-May of spring.Plant division is too early unsuitable, otherwise the temperature root of easily hindering on the low side, influence survives and grows.Grow for 5-September and shade or put half the moon, keep the light transmittance of 40%-60%, avoid the burning sun direct projection, otherwise blade is easily burnt or the edge is shrivelled, curl to plant.Can accept the direct sunlight by glass winter.Arrowroot is higher to humidity requirement, and maintenance at ordinary times can be placed on flowerpot on the flowerpot of back-off, and often to blade face and surrounding environment water spray, reaches the ground humidity around keeping, to reach the purpose that increases ambient humidity.Basin soil does not parch and will water, otherwise blade is easily because of doing the burnt limit of curling.The growth busy season, execute once light cake fertilizer or controlled release chemical fertilizer weekly, nitrogenous fertilizer is not too many.During summer high temperature, but first quarter moon is executed once thin fertilizer, and temperature is lower than 15 ℃ and stops fertilising.To keep good ventilation condition between curing period, otherwise scale insect easily takes place, influence the cauline leaf growth, reduce ornamental value.Natural 12～January of florescence.
At present, China's industry of flowers and plants development is swift and violent, and shows such trend, and promptly traditional flowers price is more and more lower, and the new varieties flowers generally all have very high price advantage.Constantly introducing the Flower New Variety kind of high-quality, is one of important channel that promotes in flowers market, the city.But velvet off-season flowering difficulty had both made and had bloomed, and the flower arrow is also considerably less, and the florescence is also short.
Summary of the invention
The present invention provides a kind of Calathea zebrina florescence regulation and control method for solving the technical problem that exists in the known technology, to satisfy the market demand of Various Seasonal in the middle of a year.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: Calathea zebrina florescence regulation and control method, at the preceding 90 days short florescences of beginning conduct that expectation is bloomed, keep 10 hours light application time interior every day at short florescence, in illumination period, keep intensity of illumination between 15000～20000lux, every day, dark period was 14 hours, continual processing 90 days; In addition, the potassium dihydrogen phosphate 1000 times (putting into 180 gram potassium dihydrogen phosphates in 180 premium on currency) of pouring (irrigating) EC=1.0～1.5 and the little fertile 7200 times mixed liquor (put into 25 at 180 premium on currency that add the peroxophosphoric acid potassium dihydrogen and restrain the little fertilizer of STEM) of commodity STEM by name weekly in the short florescence, day temperature remains on 22---and 28 ℃, nocturnal temperature keeps 21-23 ℃, daytime, optimum temperature was 23-24 ℃, made its fluctuation in the scope of minimum.Humidity remains between 75%-85%.
The good effect that the present invention has is: can make the velvet off-season flowering according to the demand in market, and the colored arrow after blooming is many, is increased to 8～9 by nature 3～4 every of the florescence, the florescence extended to 40 days by 20 days.
Embodiment
For further understanding content of the present invention, characteristics and effect, exemplify following examples now:
The contrast experiment:
Select healthy Calathea leopardina 500 basins, in the short florescence, wherein 400 basins carry out the florescence control processing according to method of the present invention at velvet.Concrete processing mode is: give illumination period every day less than 10 hours, keep intensity of illumination in illumination period between 15000～20000lux, dark period 14 hours, continual processing 90 days.Water 1000 times of liquid of potassium dihydrogen phosphate (putting into 180 gram potassium dihydrogen phosphates in 180 premium on currency) of EC=1.0～1.5 and little fertile 7200 times of mixed liquors (putting into the little fertilizer of 25 gram STEM) of commodity STEM by name weekly at 180 premium on currency that add the peroxophosphoric acid potassium dihydrogen.Day temperature remains on 22---and 28 ℃, keep 21-23 ℃ night, daytime, optimum temperature was 23-24 ℃, made its fluctuation in the scope of minimum.Humidity remains between 75%-85%.
Other 100 basins are not controlled light application time and intensity, do not water the potassium dihydrogen phosphate and the little fertilizer of STEM of EC=1.0～1.5, only do customary maintenance.
Carry out 400 basin velvets of florescence control, handle and bloomed in back 90 days carrying out florescence control, but off-season flowering, and the back flower arrow of blooming is many, and every up to 8～9, and the florescence reaches 40 days.
Do not carry out 100 basin velvets of florescence control, the nature florescence blooms, and 3～4 every on arrow, 20 days florescences are spent in the back of blooming.
The characteristics of velvet florescence control technology are: give illumination period every day less than 10 hours, dark period 14 hours, continual processing 90 days.As beginning flower forcing June, 10 of 7 o'clock to second day afternoon is full the screening the black phase, is illumination period At All Other Times, keeps intensity of illumination in illumination period between 15000～20000lux.Water and apply fertilizer based on the potassium dihydrogen phosphate of EC=1.0～1.5 of water and fertilizer synchronization and little fertilizer of commodity STEM by name, pouring once weekly, purpose is to impel the differentiation of bud, help the formation of bud like this, the little fertilizer of STEM is to be the summation of trace element simultaneously, be the substrate of enzyme, can make the pattern of urging out purer.
Attached in addition: the STEM component list
