Embodiment 1
[0020] Comparison of growth status in different greenhouse film cultivation conditions
[0021] Experimental group: Colored calla lily bulbs of the same species with similar size were germinated for 14 days at a temperature of 23°C on March 10 of the same year. After germinating, the buds were 5cm in length and placed in pots, and they were grown in a greenhouse with orange-red light conversion film ( It is determined that the daily average minimum temperature and maximum temperature of the orange-red film greenhouse is 3-5℃ higher than that of the white film greenhouse of the same thickness). The flower stems are drawn out in early May, the plant height is about 18cm, and the plant height is about 35cm in late May. Best viewing effect.
[0022] Control group 1: The color calla lily of the same species and size was accelerated on March 10th of that year at 23℃ for 14 days. After the accelerated germination, the buds were grown 5cm in the pot and placed in a greenhouse with ordinary...
Embodiment 2
[0026] Bulb germination
[0027] In the experimental group, colored calla lily bulbs of the same variety and similar size were placed at room temperature at 23°C for accelerating germination. During this period, growth promoter I of different concentrations was sprayed three times, and the germination was potted for 15 days and placed in an orange-red plastic greenhouse. Medium growth; in the control group, GA3 was soaked for 20 minutes under the same temperature or without any spraying or soaking. After accelerating germination for 15 days, it was potted and placed in an orange-red shed for growth. The flower stems were drawn out in early May and observed each The ratio of the number of flowers and leaves at the growing point, plant height, stem thickness, etc., the experimental results are shown in Table 1:
[0028]
[0029] From the above experimental results, it can be seen that spraying growth promoter I can effectively increase the flower / leaf ratio per growth point, promote ...
Embodiment 3
[0031] Promote plant growth
[0032] Color calla lily bulbs of the same variety and the same size were potted at 23°C after germination. The experimental group was sprayed with different concentrations of growth promoter 2 when the leaves were unfolded, and sprayed every 5 days for 5 times; the control group did not do it Any treatment. Observe the plant growth in early May, and the experimental results are shown in Table 2:
[0033]
[0034] Experiments have shown that spraying growth promoter II can effectively promote plant growth and resist the adverse effects caused by low temperature; while the control group has slower growth of plants, and more serious blind flowers and dwarfing of flower stems. As the concentration of SA and NAA increases, the average plant height tends to increase. If the concentration is too low, the effect is not obvious, and there are more dwarfing and blind flowers, and the abnormality of the concentration is more obvious. The effective concentration ...
