Problems solved by technology

[0003] Poinsettia is a seedling imported from abroad. Because this variety comes from abroad, there is no mature cultivation technology in China, especially in the north of the Yangtze River in China. The climate is relatively dry, the four seasons are relatively distinct, and the winter is relatively cold. The flowers are deformed, the color is not pure, and it cannot be made to bloom out of season according to market demand

example 1

[0008] Example 1: Carry out catalytic test with 500 poinsettias, advance flowering 40 days before the expected flowering period, cover 15 hours a day, light 9 hours, control light 18000-22000Lux; during the catalysis period, the catalysis period decreases The amount of nitrogen fertilizer should be used to increase the amount of phosphorus fertilizer used, that is: use 0.4g and KH per liter of Huaduoduo 20-20-20 (see Table 1 for the main component content) 2 PO 4 0.4g and Ca(NO 3 ) 2 Irrigate with 0.1g aqueous solution; in the subsequent maintenance, use clear water with a pH of 5.8-6.2 and the above-mentioned nutrient solution to irrigate. When EC>0.5, only water with clear water; when EC<0.5, water the above-mentioned nutrient solution. -23°C, 16-20°C at night, air humidity 75-80% during the day and 80-90% at night. After the flowering stops, adjust the use of fertilizers. Too much fertilizer will only make the edges of the bracts scorched. To help maintain the dark gre...

[0010] Example 2: Carry out catalytic test with 500 poinsettias, advance flowering 40 days before the expected flowering period, cover 15 hours a day, light 9 hours, control light 18000-22000Lux; during the catalytic period, the catalytic period decreases The amount of nitrogen fertilizer should be used to increase the amount of phosphorus fertilizer, that is: use 0.5g and KH per liter of Huaduoduo 20-20-20 (see Table 1 for the main component content) 2 PO 4 0.5g and Ca(NO 3 ) 2 Irrigate with 0.2g aqueous solution; in the subsequent maintenance, use clear water with a pH of 5.8-6.2 and the above-mentioned nutrient solution to irrigate. When EC>0.5, only water with clear water; when EC<0.5, water the above-mentioned nutrient solution. The flowering period should be strictly controlled. -23°C, 16-20°C at night, air humidity 75-80% during the day and 80-90% at night. After the flowering stops, adjust the use of fertilizers. Too much fertilizer will only make the edges of the b...

Abstract

The invention provides a poinsettia florescence control method which is characterized by comprising the following steps of carrying out flower forcing 40 days before an expected flowering period, and cultivating in darkness for 15h, lighting for 9h, and controlling illumination at 18000-22000Lux per day; during a flower forcing period, pouring an aqueous solution containing 0.4-0.5g of Hua Duoduo 20-20-20, 0.4-0.5g of KH2PO4 and 0.1-0.2g of Ca(NO3) per litre; during subsequent maintenance, when EC is larger than 0.5, only pouring clear water with a PH value of 5.8-6.2, and when EC is smaller than 0.5, pouring the nutrient solution, wherein during the flower forcing period, the temperature needs to be strictly controlled at 21-23 DEG C in the daytime and 16-20 DEG C at nighttime, and the air humidity needs to be controlled to be 75-80 percent at daytime and 80-90 percent at nighttime.

Description

technical field [0001] The invention belongs to the field of flower cultivation methods; in particular, the field of poinsettia cultivation methods. Background technique [0002] Poinsettia (Euphorbia pulcherrima), also known as Christmas tree, orangutan wood, and ivory red, is native to Mexico. Euphorbia is a deciduous erect shrub with alternate single leaves, egg-shaped oval to broad-lanceolate, 10 to 15 cm long, and soft hairs on the back , the leaves on the top of the branches are relatively narrow (also known as bracts), and the leaf margins are blunt, lobed or entire, and the leaves under the stem top inflorescence are narrow, bract-shaped, usually entire, and appear when blooming Red, the terminal cup-shaped inflorescences are arranged in cymes, the involucre is light green, with yellow glands, the whole inflorescence is set off by red bracts, the stems are grayish brown and the tender stems are green, smooth, and contain white latex. The flowering period is from Dec...
