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%...

Abstract

The invention relates to a method of increasing the coldness tolerance of red palm using NO, and in particular a method of increasing the coldness tolerance of red palm applying external source nitric oxide. At the initial stage of red palm budding, the date is normally selected between September and October, after the dew dries on the selected sunny day or cloudy day morning, the leaves are sprayed with the SNP solution at 8-9 o'clock, the spraying continues until the solution drips from the red palm leaves, the spraying is applied once every 3 days, and continuously for 3 times. When the method is adopted, after the red palms are transplanted and the red palms survive normally until the initial stage of buds emerging, the SNP spraying treatments on leaf surfaces are conducted, the coldness tolerance of red palm can be significantly increased, and the method has the advantages of being the simple in process and easy to operate, free of secondary pollution and low in cost, and large area treatments are facilitated.

Description

technical field [0001] The invention relates to a method for improving the cold resistance of plants, in particular to a method for improving the cold resistance of Anthurium anthurium by using NO, and belongs to the field of plant science and technology. Background technique [0002] Anthurium andraeanum, also known as Anthurium, Anthurium, etc., is a perennial epiphytic evergreen herb of the genus Anthurium in the family Araceae, and its main origin is the tropical and subtropical rainforest regions of South America. Anthurium flowers are bright and eye-catching, with unique and beautiful flower posture and long-lasting flowering period. They are the best-selling tropical flowers in the world and have extremely high ornamental value and economic value. However, Anthurium is a temperature-loving flower with poor cold resistance. The growth temperature needs to be above 15°C, and chilling damage is easy to occur if it is lower than 12°C. When cultivated in the middle and lo...
