Description
Technical Field
The invention relates to a flower production and cultivation technology, in particular to a summer forcing cultivation method for edible summer chrysanthemum.
Background
The charcot belongs to Compositae, and is distributed in Taiwan and Yinhui and Java in Taiwan in China. Summer chrysanthemum is a evergreen herb, short in stem, large in leaf, one to several flower stems, arched, large in flower and butterfly. It is heat-loving and yin-resistant, is a temperature-sensitive flower, and is suitable for the environment with multiple temperatures and ventilation. The required luminosity is about 40% of full sunlight, relative humidity 70%, temperature 15-30 ℃. The common summer chrysanthemum season is 11 months to 2 months in the next year, and the flowering phase is as long as one season.
Summer chrysanthemum blooms in summer and autumn and needs low-temperature forcing culture. For a long time, flower forcing is basically carried out in northern China by adopting high mountain flower forcing or flat ground fan water curtain low-temperature flower forcing to carry out summer forcing culture. The transportation cost of the flower forcing in the high mountains is high, and the maintenance cost of the high mountain base is also high. The cost of the single finished summer chrysanthemum can be improved by flower forcing in a high mountain base; the low-temperature flower forcing of the flat-ground fan water curtain can not be reduced to a low enough temperature in summer, and the low-temperature time is not long enough, so that the flower forcing and stalk emergence rate is low, the stalk pumping time is slow, and the quality of finished flowers can deviate.
Disclosure of Invention
In order to overcome the problems of the prior art, the invention aims to provide a cultivation method for promoting edible summer chrysanthemum in summer, which is characterized by mainly comprising the following steps:
step one, moving the mature big chrysanthemum seedlings into a greenhouse 4-5 months before the expected flowering, keeping the temperature of the greenhouse at 24-32 ℃ in the daytime and 18-26 ℃ at night, and periodically applying fertilizers;
step two, after 1 month, keeping the temperature of the greenhouse at 24-26 ℃ in the daytime and 18-20 ℃ at night, periodically applying fertilizers, and simultaneously spraying 3-7ppm paclobutrazol (pp333) on leaf surfaces for 2-4 times;
and step three, keeping the temperature of the greenhouse at 25-28 ℃ in the daytime and 20-22 ℃ at night 2-3 months before the expected blossoming, and applying fertilizers regularly until the chrysanthemum blossoms.
Preferably, in the first step, the temperature of the greenhouse is kept between 30 and 32 ℃ in the daytime and between 24 and 26 ℃ in the nighttime.
More preferably, the first step further comprises adjusting the light in the greenhouse to 10000-12000Lux, and applying N: p: the K ratio is 20: 20: 20, the EC value of the fertilizer water is kept between 1.0 and 1.2 when the fertilizer is applied once.
Or preferably, the second step further comprises adjusting the illumination in the greenhouse to 12000-15000Lux, changing the fertilizer into N: p: the K ratio is 9: 45: 15, the flower forcing fertilizer is used once a week, the concentration of the fertilizer is that the EC value of water for fertilizing is kept between 1.0 and 1.2, and 5ppm paclobutrazol (pp333) is sprayed on the leaf surfaces, once a week and three times continuously.
More preferably, in the second step, after one month of growth and cultivation, when more than 90% of chrysanthemum subjected to flower forcing is subjected to stalk extraction and the stalks grow to about 10cm, the fertilizer is stopped once, and the chrysanthemum is thoroughly watered with clear water with an EC value of less than 0.2 once.
Or preferably, the third step further comprises the step of adjusting the illumination in the greenhouse to 15000-18000Lux, changing the fertilizer into N: p: the proportion of K is 20: 20: 20, once per week, keeping the EC value of fertilizer water at 0.8-1.0, and stopping fertilizing after 6 times continuously until the chrysanthemum flowers.
The transformation from vegetative growth to stem-drawing flowering of the chrysanthemum is facilitated by large temperature change besides the requirement that the temperature is low enough, and the transformation from vegetative growth to stem-drawing flowering of the chrysanthemum is facilitated by chemical agent paclobutrazol (pp333) for inhibiting growth. The forcing culture method adopts the earlier stage to obviously improve the growth and cultivation temperature of the chrysanthemum, enters the flower forcing period to greatly reduce the cultivation environment temperature of the chrysanthemum and combines the use of paclobutrazol (pp333) to inhibit the vegetative growth of the chrysanthemum, so that the period is rapidly converted from nutrient growth to peduncle-drawing flowering.
The invention has the following beneficial effects: the method is used for promoting the chrysanthemum flower in summer in North China, the stem drawing speed is high, the stem drawing rate is high, and the quality of the finished flower is high.
