Abstract

The invention belongs to the field of floriculture methods, and relates to a method for regulating the flowering period of medinilla magnifica. The method comprises the following steps: flower forcing is carried out for 4 months before the expected flowering period, in the flower forcing period, the temperature is kept at 27 DEG C by day and 23-24 DEG C at night, the humidity is kept at 75-85% by day and 70-80% at night, the illumination intensity is kept at 24000LUX, and the illumination time is kept over 8 hours each day; the following fertilizers are applied: potassium nitrate with the pH value of 5.5 and the EC value of 0.55, 20-10-20, the pH value of 5.5 and the EC value of 0.55, 15-20-25, and the pH value of 5.5 and the EC value of 0.55; the method of alternate watering is as follows: the potassium nitrate is applied once every 3 days, and after being watered for 3-4 times, the medinilla magnifica is watered with clean water once every 3 days, and watered for 3-4 times; the potassium nitrate, the clean water, the 20-10-20, the clean water, the 15-20-25 and the clean water are applied for repeated watering successively according to the method until the medinilla magnifica flowers.

Description

Lotus lantern florescence regulation and control method

Technical field

The invention belongs to field of floriculture methods; Lotus lantern cultivating method field particularly.

Background technology

Precious lotus lamp (Medinilla magnifica) is that the sour foot lever of Melastomataceae (Melastomataceae) belongs to (MedinillaGaud) plant, is the Flower New Variety kind that has ornamental value.Precious lotus lamp is a perennial plant, and single leaf is to life, the blade oval, and blade is bigger, and leaf heavy leather matter is glossy, dark green leaf, the spire blade back is slightly filbert, the vein depression, the full edge of blade, leaf margin is undulation, no petiole.Young leaves and inflorescence grow from the base portion joint portion central authorities of opposite leaf sheet.Inflorescence is conical, bract pink, corolla aubergine.Because inflorescence is bigger, peduncle is more elongated, makes the oil lamp that whole inflorescence is sagging as hang.Can go on the market when inflorescence length reaches 15cm, under the normal condition, precious lotus lamp flowering stage of North China in February October to next year, under the condition more than 16 ℃, see the florescence to be 2 months.

China's industry of flowers and plants development is swift and violent, and shows such trend, and promptly traditional flowers price is more and more lower, and the new varieties flowers generally all have very high price advantage.Constantly introducing the Flower New Variety kind of high-quality, is one of important channel that promotes in flowers market, the city.

Do not carry out at present being prone to of precious lotus lamp of florescence control and spend deformity (promptly normal in appearance, Hua Sui is not full to be hollow form), pattern is impure, and petal is little, and (about 1～1.5cm) promptly stops growing, and growing point can not normally go out flower.And can not make its off-season flowering according to the market demand.Along with the increase that precious lotus lamp is promoted at home, people are more and more higher to its quality requirement.For it can be opened and supply the market other seasons in 1 year,, open during May Day or National Day and listing simultaneously, can further expand the market space of precious lotus lamp like this, help the economic benefit of comparatively long-range this kind of performance as the Spring Festival.

Summary of the invention

At this phenomenon, the present invention aims to provide a kind of lotus lantern florescence regulation and control technology, satisfies the market demand of different times in the time of with raising buds of lotus lantern grass quality.

Lotus lantern florescence regulation and control method, push ahead began to carry out flower forcing in 4 months the flowering stage in expection, the flower forcing phase should strictly be controlled temperature, humidity, flower forcing phase day temperature is 27 ℃, night be 23 ℃～24 ℃, daytime humidity be 75%～85%, night humidity be 70%～80%, illumination remains on 24000LUX, illumination every day is more than 8 hours, illumination is not enough can to influence its pattern.Impose down fertilizer: 1. potassium nitrate, pH value 5.5, EC value 0.55,2. 20-10-20, pH value 5.5, EC value 0.55,3. 15-20-25, pH value 5.5, EC value 0.55; The pouring of rotating, method is as follows; Potassium nitrate of pouring in per 3 days waters 3～4 times, then, clear water of pouring in per 3 days waters 3～4 times, then, 20-10-20 of pouring in per 3 days, water 3～4 times, then, clear water of pouring in per 3 days, water 3～4 times, then, 15-20-25 of pouring in per 3 days waters 3～4 times, then, clear water of pouring in per 3 days waters 3～4 times, then, potassium nitrate of pouring in per 3 days, water 3～4 times ... method repeats pouring successively according to this: potassium nitrate, clear water, 20-10-20, clear water, 15-20-25, clear water, till blooming.Pouring is as the criterion to irrigate.

Compared with prior art, the invention has the beneficial effects as follows: innovated the lotus lantern florescence regulation and control technology, improved buds of lotus lantern grass quality, made the buds of lotus lantern colour purity just, Hua Sui is full, and each growing point all has petal and petal normal growth.Off-season flowering and kind of blooming period prolonging to 4 month have been realized.Make the growing and cultivating of precious lotus lamp comply with the market demand.

Embodiment

The flower forcing phase is to the requirement of temperature, humidity, illumination and moisture fertilizer: temperature control will be strict with can not be fluctuated, otherwise be prone to the deformity flower.Strict control is also wanted in illumination, and the illumination deficiency then influences its pattern.To pay attention to the control of flowers in the flower forcing stage to moisture content, water inquire for dried see wet.Water Da Yi causes leaf abscission (balck shank), and influences cuttage in the future, is lowered into motility rate.The flower forcing phase, the temperature temperature was 27 ℃ of daytimes to temperature, humidity, illumination and liquid manure control, and 23 ℃～24 ℃ of nights, humidity are daytime 75%～85%, and night 70%～80%, illumination remain on 24000LUX, and illumination every day is more than 8 hours.Liquid manure: 1. potassium nitrate, pH value 5.5, EC value 0.55,2. 20-10-20 (composition sees Table), pH value 5.5, EC value 0.55,3. 15-20-25 (composition sees Table two), pH value 5.5, EC value 0.55; The pouring of rotating, method is as follows; Potassium nitrate of pouring in per 3 days waters 3～4 times, then, clear water of pouring in per 3 days waters 3～4 times, then, 20-10-20 of pouring in per 3 days, water 3～4 times, then, clear water of pouring in per 3 days, water 3～4 times, then, 15-20-25 of pouring in per 3 days, clear water waters 3～4 times, then, clear water of pouring in per 3 days waters 3～4 times, then, potassium nitrate of pouring in per 3 days, water 3～4 times ... method repeats pouring successively according to this: potassium nitrate, clear water, 20-10-20, clear water, 15-20-25, clear water is till blooming back four months.(flower was opened substantially and lost this moment) pouring is as the criterion to irrigate.The pouring clear water is in order to regulate the too high phenomenon of basin soil salinity.In the flower forcing process, leaf bud can occur, should in time destroy, not so can dead or and the nutritious competition of petal the petal folding.

Method is regulated and control lotus lantern florescence in the employing in any season, all can bloom at 4 months and kind of blooming period prolonging to 4 month.And the buds of lotus lantern colour purity just, and Hua Sui is full, and each growing point all has petal and petal normal growth.
