Embodiment Construction

[0008] For being able to further understand content of the present invention, feature and effect, enumerate following embodiment hereby:

[0009] Comparative Experiment:

[0010] Choose 500 pots of healthy velvet arrowroot, and in the velvet flower-promoting period, wherein 400 pots carry out florescence regulation and control process according to the method of the present invention. The specific treatment method is as follows: the light period is less than 10 hours per day, the light intensity is kept between 15,000 and 20,000 lux during the light period, the dark period is 14 hours, and the treatment is continued for 90 days. Water 1000 times of potassium dihydrogen phosphate (180 grams of potassium dihydrogen phosphate in 180 liters of water) of EC=1.0~1.5 once a week and 7200 times of micro-fertilizer mixed solution of trade name STEM (after adding potassium dihydrogen superphosphate Put 25 grams of STEM micro-fertilizer in 180 liters of water). The temperature is kept a...

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

technical field [0001] The present invention relates to a kind of plant cultivation technique; especially the florescence regulation technique. Background technique [0002] Velvet arrowroot, also known as zebra arrowroot, Latin Calathea Warscewiczii, is a plant of the Arrowroot family Arrowroot. The leaves of velvet arrowroot are oval, 40-45cm long and 25-27cm wide. The back of the leaf is purple, and the leaf surface is inlaid with dark green spots. The leaves open during the day and close at night, and the flower arrows come out from the leaves, and the flowers are white. [0003] The propagation of arrowroot plants is mostly carried out in combination with repotting in spring from April to May. The ramets should not be too early, otherwise the low temperature will easily damage the roots and affect survival and growth. May-September: Shade the plants or put them in half shade, keep the light transmittance of 40%-60%, and avoid direct sunlight, otherwise the leaves will...
