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 ...
