Abstract

The invention discloses a method for controlling the florescence of narcissi. According to the method, seeds are sown 100-150 days before an expected pre-bloom date; shading treatment starts to be conducted 30-40 days before the expected pre-bloom date; light supplementing treatment is conducted 15-20 days before the expected pre-bloom date; a No.2 1000-fold solution of flower fertilizer is applied once every two days before the shading treatment; a No.1 800-fold solution of the flower fertilizer is applied once every three days after the shading treatment. The method has the advantages that the florescence of the narcissi can be controlled so that the narcissi can bloom when needed.

Description

A kind of method at regulation and control narcissus florescence

Technical field

The invention belongs to field of floriculture methods, particularly a kind of method at regulation and control narcissus florescence.

Background technology

Narcissus, also known as: polyanthus, fairy walking over ripples, golden small cup Yin Tai, Lip river god perfume prince wife, flower etc. in beautiful exquisite, gold and silver platform, snow, Belong to Amaryllidaceae Narcissus herbaceos perennial, originate in China, daffodil is distributed in the Zhejiang of East Asia and China's Mainland, Fujian The ground such as offshore islands, are wherein concentrated with ZhangZhou, at present by artificial introducing and planting again the most.Narcissus originates from Hubei Jiangling.? Existing more than the 1000 year cultivation history of China, is one of Chinese tradition famous flower.

Narcissus, the whole world has kind more than 800, and kind more than 10 therein such as daffadowndilly, hoppetticoat daffodil etc. have high sight Reward is worth.Flower is white, in corymb, the long and narrow banding of leaf, and the Chinese narcissus bulb being made from has functions that clearing heat and detoxicating.

It is distributed in the ground such as Zhejiang, the Coastal island area in Fujian of East Asia and China's Mainland, wherein concentrated the most with ZhangZhou, again By artificial introducing and planting.There is cultivation in China the Tang Dynasty before more than 1300 years, quite extensive in Chinese open countryization distribution, main point Cloth is in the southeastern coastal areas, the most famous with Shanghai Chongming County and Zhangzhou, Fujian narcissus, before centuries, the ground such as Suzhou, Jiading Also produce narcissus.In addition to common white narcissus, also the kind of a yellow is daffadowndilly.Daffodil is in Europe cultivation With a long history.Since the 1830's, the state such as Holland, Belgium, Britain has done greatly to the breeding of daffodil and breed improvement Measure work, cultivar has reached 26000 so far, also have new varieties to be born every year.Chinese cultivated daffodil started from for 19th century End.

But there is presently no good method and adjust the florescence of narcissus it is ensured that it was bloomed within the time needing.

Content of the invention

It is an object of the invention to provide a kind of method at regulation and control narcissus florescence is so as to not only can open in the period of specified Flower is it can also be ensured that its flowering quality, kind of blooming period prolonging.

Realize above-mentioned purpose and adopt a kind of following technical proposals: method at regulation and control narcissus florescence, 100 before expection is bloomed～ Sowing in 150 days, proceeds by shading treatment in 30～40 days before expection is bloomed；Until expecting 15～20 days before blooming, mended Light is processed；Applied once the more No. 2 1000 times of liquid of flower every 2 days before carrying out shading treatment；After carrying out shading treatment, Apply once the more No. 1 800 times of liquid of flower every 3 days.It is an advantage of the invention that can be regulated and controled so as to need to open the florescence of narcissus Bloom when flower.

Further, described shading treatment is that daily 8:00 to 17:00 carries out full sun, 17:00 to morning next day 8:00 All use black cloth shading.

Further, it is that daily 8:00 to 16:00 is carried out full sun that described light filling is processed, and 16:00 to 19:00 increases and continues Illumination 3 hours, intensity of illumination is 30～35w.

Flower the more No. 1 general fertilizer (20-20-20) compound fertilizer is that the water compatible quick-acting fertilizer of U.S.'s scotts original packing-spend is many One of multi-series, feature is: 1, nitrogen: phosphorus: the basic recipe of potassium=1:1:1, adds m 77 trace and REE elements of world patent Crop nutrient is made more to equalize.2nd, each agricultural experiment in whole world institute, agricultural school, farm, using flower the more 20-20-20 Yield multiplication, improve quality all can be obtained, shorten the excellent effect in term, and be successfully used in half soilless culture.3rd, add It is added in irrigation water, excessive alkali in water can be neutralized.4th, fertilizer absorbed ground efficiency higher compared with similar-type products, be the current whole world Range and the most salable formula.5th, maxima solubility is 417 g/l.The more No. 1 1000 times of liquid of flower be 1 gram is spent many Many No. 1 plus 1000 milliliters of water preparations.

Flower the more No. 2 (10 30 20) is the water compatible quick-acting fertilizer of U.S.'s scotts original packing-spend one of many multi-series, special Point is fertile nitrogen: phosphorus: the ratio of potassium=1:3:2 can be effectively facilitated bud differentiation, the quantity making petal big and strong and increasing flower.Flower The more No. 2 800 times of liquid are 1 gram of flower the more No. 2 plus 800 milliliters of water.

The more No. 1 (20 20 20) fertilizer formula of flower: (following percentage is weight percentage by weight)

Total nitrogen content is 20%(wherein nitrate nitrogen content 6.11%, ammonium nitrogen content 3.89%, and urea nitrogen content is 10%), Water-soluble phosphoric anhydride content is 20%, and water soluble oxidized potassium content is 20%, and water soluble oxidized content of magnesium is 0.05%, and Boron contents are 0.0068%, Chelating state copper content is 0.0036%, and chelated ferrous iron content is 0.05%, and Chelating state manganese content is 0.025%, Chelating state Zn content is 0.0025%, and molybdenum content is 0.0009%.

The more No. 2 (10 30 20) fertilizer formulas of flower: (following percentage is weight percentage by weight)

Total nitrogen content is 10%(wherein nitrate nitrogen content 5.1%, ammonium nitrogen content 4.9%), water-soluble phosphoric anhydride content is 30%, Water-soluble potassium content is 20%, and water soluble magnesium content is 0.6%, and Boron contents are 0.0068%, and Chelating state copper content is 0.0036%, chela Closing state iron content is 0.05%, and Chelating state manganese content is 0.025%, and Chelating state Zn content is 0.0025%, and molybdenum content is 0.0009%.

The invention has the advantage that not only can enable to bloom when specific among 1 year of narcissus, to meet as flower Altar, the demand of flower border material, meet market demand, fill up red-letter day vacancy；The duration bloomed of narcissus also can be greatly prolonged, And can ensure that flower characteristic, improve ornamental value.

Specific embodiment

This experiment is divided into invention group and control group, and every group processes 200 plants.
