|
|
| Sowing Method: | |
3-5 seeds per plug, tap root formation, sowing directly into final pots or field is recommended
|
|
| Germination: | |
7-12 days at 18-24 °C, in media with low soluble salt levels and pH: 5.5-7.0. Requires light for germination. Do not cover seeds. Keep soil slightly moist but not wet.
Avoid direct sunlight by shading seeds after sowing. Papaver form a tap root. Avoid the plants roots grow into soil underground, because if the trays are moved, the roots will tear up and this can cause growth inhibition.
|
|
| Plug Culture: | |
From Stage II reduce the soil moisture, but the plug should not dry out and reduce the temperature to 15-18 °C. Do not let soluble salt level rise above 0,75 EC. Start fertilization at 50-75 ppm nitrogen in a well balanced formula. During Stage III and Stage IV fertilization levels can be increased up to 200 ppm.
|
|
| Growing On: | |
4-6 weeks after sowing transplant 1 plant into a pot (10-18 cm) and 1-2 plants into a container (3-5 l). For flowering pot production ensure a good pot size to encourage root growth, thus improving the plant quality. Plant cut flowers (frost free) in 35-40 x 35-40 cm space.
|
|
| Media: | |
Use a well-drained, growing substrate with 15-30 % clay, 10-15 % parts (e. g. bark, perlite, sand), 2-3 kg/m³ complete balanced fertilizer, 0-3 kg/m³ slow release fertilizer (3-6 months), iron-chelate, micronutrients, pH: 5.5-7.0. Field: loamy sandy humus soils with a good drainage.
Standard fertilization: 80-100 g/m² of a slow release fertilizer.
|
|
| Photoperiod / Light: | |
Long day plant. Keep light levels high. The long day (14-16 h) supports the flower initiation. In winter additional assimilation light in combination with warm temperatures are required for early forcing.
|
|
| Temperature: | |
Grow at 10-15 °C. Avoid temperatures above 25 °C. In winter indoors frost free at 3-5 °C or outdoors. For wintering the leaf rosette formation and the root development in pots should be very good. In spring the plants start to grow for 10-12 weeks at 10-15 °C and long day. If cultivated at high temperatures, the light intensity should be high for good plant quality. Cold temperatures at 5 °C will increase the cultivation time by 2-4 weeks. A chilling period (vernalization) is required for flower initiation.
|
|
| Fertilization: | |
High fertilization levels are required. Fertilize the crop weekly with 150-200 ppm nitrogen (at 3 kg/m³ slow release fertilizer in substrate), using a complete balanced fertilizer. Don't fertilize after mid September. In spring fertilize with 150-200 ppm nitrogen of a potassium balanced fertilizer (N: K2O-ratio: 1:1,5). Avoid high ammonium and high nitrogen levels. High nitrogen levels are the cause that the stems and the foliage are stretched and the plant fall apart. When the buds are visible, additional foliage fertilization should be carried out. Prevent magnesium deficiency by applying magnesium sulphate (0,05 %) 1-2 times and in case of iron deficiency apply iron-chelate for 1-2 times. Field: If necessary according to analysis, improve the soil with 80-100 g/m² of a slow release fertilizer, applied in several portions.
|
|
| Cut Flowers: | |
Cut flower stems can be harvested, when the buds are thickly swollen and only a short time is left before flowering. Burn down the cuts and do not cut the same spot anymore later so that the milk flow stops. Put the stems immediately in water. Vase life: 5-10 days. Cold storage is not recommended. The seedpods can be used for dried flower production. 100 % crop is achieved in the second year.
|
|
| Cultural Hints: | |
P. orientale needs constant irrigation and fertilization, because drought stress and shortage of nutrition support chlorosis and necrosis on foliages and the flower stems are not stretched.
|
|
Hint
The cultural recommendations are based on results from trials conducted under Central European conditions. Different conditions in other parts of the world may lead to deviations in results achieved.
