Problems solved by technology

The cost of a single finished summer chrysanthemum plant will increase a lot after flower urging in alpine bases; the low-temperature flower urging of flat fan water curtains will cause the flower urging rate to be low due to the fact that the summer temperature cannot drop low enough and the low temperature time is not long enough. The time to draw stems is slow, and the quality of finished flowers will also deviate

Embodiment 1

[0017] Four and a half months before the expected flowering, select mature chrysanthemum seedlings that can enter the flowering and put them in the predetermined greenhouse, keep the cultivation temperature in the greenhouse at 24-26°C during the day and 18-20°C at night, and apply N with water once a week: The ratio of P: K is 20:20:20, Huawuque balanced fertilizer once, and the concentration of fertilizer application is such that the EC value of fertilizer and water is kept between 1.0-1.2. After one month, keep the temperature of the greenhouse at 24-26°C during the day and 18-20°C at night, and change the fertilizer to Huawuqian high-phosphate fertilizer with a ratio of N:P:K of 9:45:15, and apply it once a week. The fertilizer concentration is such that the EC value of the fertilizer and water is maintained between 1.0-1.2, and 6 ppm paclobutrazol (pp333) is sprayed on the leaves once a week for three consecutive times. Two and a half months before the expected flowering,...

Embodiment 2

[0019] Four and a half months before the expected flowering, select mature chrysanthemum seedlings that can be used to promote flowering and put them in the predetermined greenhouse. 10000-12000 Lux, and apply Huawuque balanced fertilizer with N:P:K ratio of 20:20:20 once a week with water, and the fertilizer application concentration is such that the EC value of fertilizer and water is kept between 1.0-1.2. After one month, reduce the temperature of the greenhouse to 24-26°C during the day and 18-20°C at night, adjust the light in the greenhouse to 12000-15000Lux, and change the fertilizer to flowers with a N:P:K ratio of 9:45:15. There is no shortage of high-phosphate fertilizer, and it is applied once a week. The fertilizer concentration is that the EC value of fertilizer and water is kept between 1.0-1.2. At the same time, 5 ppm paclobutrazol (pp333) is sprayed on the leaves once a week, three times in a row. After a month of growth and cultivation, more than 90% When all ...

Embodiment 3

[0021] Four and a half months before the expected flowering, select mature chrysanthemum seedlings that can enter the flowering force and put them in the predetermined greenhouse. 10000-12000 Lux, and apply Huawuque balanced fertilizer with N:P:K ratio of 20:20:20 once a week with water, and the fertilizer application concentration is such that the EC value of fertilizer and water is kept between 1.0-1.2. After one month, reduce the temperature of the greenhouse to 24-26°C during the day and 18-20°C at night, adjust the light in the greenhouse to 12000-15000Lux, and change the fertilizer to flowers with a N:P:K ratio of 9:45:15. There is no shortage of high-phosphate fertilizer, and it is applied once a week. The fertilizer concentration is that the EC value of fertilizer and water is kept between 1.0-1.2. At the same time, 5 ppm paclobutrazol (pp333) is sprayed on the leaves once a week, three times in a row. After a month of growth and cultivation, more than 90% When all the...

Abstract

The invention relates to a cultivation method for forcing chrysanthemum in summer. The cultivation method is characterized by mainly comprising the following steps of (1) transplanting mature seedlings of the chrysanthemum into a greenhouse in 4 to 5 months before expected blossoming, keeping the temperature of the greenhouse to be ranged from 24 to 32 DEG C in the daytime and to be ranged from 18 to 26 DEG C at night, and regularly fertilizing; (2) after 1 month, keeping the temperature of the greenhouse to be ranged from 24 to 26 DEG C in the daytime and to be ranged from 18 to 20 DEG C at night, regularly fertilizing, and meanwhile, foliage spraying 3 to 7ppm paclobutrazol (pp333) for 2 to 4 times; and (3) keeping the temperature of the greenhouse to be ranged from 25 to 28 DEG C in the daytime and to be ranged from 20 to 22 DEG C at night in 2 to 3 months before expected blossoming, and regularly fertilizing until the chrysanthemum blooms.

Description

technical field [0001] The invention relates to flower production and cultivation techniques, in particular to a cultivation method for promoting edible summer chrysanthemums in summer. Background technique [0002] Summer chrysanthemum belongs to Compositae, native to tropical and subtropical alpine regions of Asia, and distributed in Taiwan, the Philippines, Java and other islands. Summer chrysanthemum is an evergreen herb with short stems, large leaves, one to several flower stems, arched, large flowers and butterfly shape. Shade-tolerant and heat-loving, it is a temperature-sensitive flower, suitable for growing in a warm and ventilated environment. The required luminosity is about 40% of the full sun, the relative humidity is 70%, and the temperature is 15°C-30°C. The common summer chrysanthemum season is from November to February of the following year, and the flowering period lasts for one season. [0003] Summer chrysanthemum needs low temperature to promote culti...
