Embodiment 1

[0026] Example 1 Effect of Fertilization on the Ornamental Quality of Potted Flowers

[0027] Choose 90 pots of "Black Knight" potted flowers that are more than one year old, healthy and consistent in growth, each pot contains about 10 buds, plant height is 40cm, canopy diameter is 50cm, flowerpot diameter and height are both 30cm, and soil content is about 10kg. On the 1st, put the potted flowers in the greenhouse to promote flowering. The night temperature in the greenhouse is 14-16°C, the daily temperature is 24-26°C, the humidity is 85%-90%, the light is more than 14 hours, and the light intensity is 5000Lx. If there are new buds sprouting during the flowering period, wipe them off in time.

[0028] Set up test group 1, test group 2 and blank group, with 30 pots in each group. Test group 1 was fertilized twice a year, the first time after flowering in early May, and the residual flowers were removed before fertilization. Loosen the soil on the surface of the potted flowe...

Embodiment 2

[0032] Example 2 The influence of greenhouse flowering on the early flowering of German iris 'Black Knight' (taking New Year's Day flowering as an example)

[0033]Choose 90 pots of "Black Knight" potted flowers that are more than one year old, healthy and consistent in growth. Fertilize according to the method of test group 1 in Example 1, and if there are new buds sprouting during the flowering period in the greenhouse, then wipe them off in time.

[0034] Set up test group 1, test group 2 and blank group, with 30 pots in each group. Test group 1 was placed in the greenhouse on October 1, and the night temperature was maintained at 14-16°C and the day temperature at 24°C by means of temperature increase, light supplement, and humidification. -26°C, humidity 85%-90%, light for more than 14 hours, light intensity 5000Lx, and ventilation once in the morning and evening. The experimental group 2 was placed in a simple greenhouse without measures such as temperature increase and...

Embodiment 3

[0038] Example 3 The effect of the flowering time in the greenhouse on the early flowering of German iris 'Black Knight' (taking New Year's Day flowering as an example)

[0039] Choose 120 pots of "Black Knight" potted flowers that are more than one year old and grow healthily and consistently. Fertilize according to the method of test group 1 in Example 1, if there are new buds to germinate during the flowering period in the greenhouse, then wipe them off in time.

[0040] Set up test group 1, test group 2, test group 3, test group 4, test group 5 and blank group, with 20 pots in each group, on September 10, September 20, October 1 and October 2011 Put them into the greenhouse on the 10th and October 20th, and the conditions for promoting flowering in the greenhouse are the same as in Example 1, and the blank group is placed on the ground cloth, and it is managed routinely.

[0041] Test results: By the time of New Year's Day, 1-2 stems of the test group 1 had withered, the ...

Abstract

The invention discloses a forcing culture method of German iris 'black knight'. The method includes following steps: 1), choosing iris potted flowers more than one year old, healthy in growth and uniform in growing trend, fertilizing after flowering in early May is finished and flower bud differentiation at the end of September is basically completed, wherein the fertilizing proportion meets a formula N:P:K=20:20:20; 2), placing the potted flowers in a greenhouse about 90 days before the expected flowering period from the beginning of October when flower buds distinguishable by naked eyes are formed to the beginning of December, and controlling culture conditions for flower forcing. By the method, florescence of the German iris 'black knight' can be effectively brought forward, and by fertilizing and controlling time for greenhouse flower forcing and greenhouse culture conditions, the florescence can be effectively brought forward to expected New Year's Day and Spring Festival, and a basis is provided for development of lunar-new-year German iris 'black knight'.

Description

technical field [0001] The invention relates to a method for promoting cultivation of ornamental plants, in particular to a method for promoting cultivation of a German iris variety 'Black Knight', and belongs to the technical field of flower promotion cultivation. Background technique [0002] Iris is the general name of Iridaceae Iris, German Iris ( Iris germanica L.) is a hybrid population of the genus Iris, mainly Iris rufica ( Iris variegata ) and vetiver iris ( Iris Pallida ) hybrids, since the 19th century, have been greatly enriched in flower color, flower stem height and growth characteristics through continuous cross-breeding since the 19th century (Guo Jinyan et al., "Research Progress in Rhizome Iris Horticulture", "Acta Horticultural Science" , 2006, 33(5): 1149-1156). 'black Knight'( Iris germanica ‘Black Knight’) is a mesophytic heat-resistant and drought-resistant horticultural new species of Iris germanus. It was introduced from abroad in recent...
