Embodiment 1
[0022] (1) In the initial stage of anthurium budding, about 10% of anthurium plants appear flower buds.
[0023] (2) Configure 0.3mmol / L SNP spray solution.
[0024] (3) In September-October, spray the leaves at 8-9 o'clock after the dew dries on a sunny or cloudy day; spray evenly with a watering can, and spray 800mL of SNP solution evenly with a watering can per square meter of potted flowers until red Spray once every 3 days until the leaves of palm seedlings drip, and spray 3 times in a row.
[0025] (4) Transfer the sprayed potted flowers to a low-temperature culture room at 10°C for 15 days, and observe the cold resistance of Anthurium.
[0026] The test results are shown in Table 1. The test results show that: the SNP of 0.3mmol / L is used to treat the Anthurium seedlings, and compared with the contrast sprayed with distilled water, the cold damage index is greatly reduced, which is only 54.21% of the contrast; the electrical conductivity and MDA content are only 55.85...
Embodiment 2
[0028] (1) In the initial stage of anthurium budding, about 10% of anthurium plants appear flower buds.
[0029] (2) Configure 0.6mmol / L SNP spray solution.
[0030] (3) In September-October, spray leaves at 8-9 o'clock when the dew dries on a sunny or cloudy day; spray evenly with a watering can, and evenly spray 600mL of SNP solution with a watering can per square meter of potted flowers, spray until red Spray once every 3 days until the leaves of palm seedlings drip, and spray 3 times in a row.
[0031] (4) Transfer the sprayed potted flowers to a low-temperature culture room at 10°C for 15 days, and observe the cold resistance of Anthurium.
[0032] The test results are shown in Table 1. The test results show that: 0.3mmol / L of SNP treated Anthurium seedlings, compared with the contrast sprayed with distilled water, the cold damage index decreased significantly, which was 74.69% of the control; the electrical conductivity and MDA content were only the control 66.95% and ...
Embodiment 3
[0034] (1) In the initial stage of anthurium budding, about 10% of anthurium plants appear flower buds.
[0035] (2) Configure 0.9mmol / L SNP spray solution.
[0036] (3) In September-October, spray leaves at 8-9 o'clock after the dew dries on a sunny or cloudy day; spray evenly with a watering can, and spray 400mL of SNP solution evenly with a watering can per square meter of potted flowers until red Spray once every 3 days until the leaves of palm seedlings drip, and spray 3 times in a row.
[0037] (4) Transfer the sprayed potted flowers to a low-temperature culture room at 10°C for 15 days, and observe the cold resistance of Anthurium.
[0038] The test results are shown in Table 1. The test results show that: 0.3mmol / L of SNP treated Anthurium seedlings, compared with the contrast sprayed with distilled water, the cold damage index decreased significantly, which was 81.92% of the control; the electrical conductivity and MDA content were only the control 77.78% and 96.19%...
