Embodiment 1
[0020] A method for segmented chlorosis of citrus, the method may further comprise the steps:
[0021] a. Storage chlorosis treatment: Spray the citrus with 50 mg / L anti-falling agent and 0.1% thiophanate-methyl on the surface of the citrus 1 day before fruit picking. Add ethylene to the green storage for chlorotic treatment, the ethylene concentration is 3 μL / L, the flow rate is 10 mL / min, the temperature of the chlorotic storage is controlled at 20 ° C, the relative humidity is 90%, and the treatment time is 26 hours. Circulating fan for air circulation treatment, air circulation treatment is once every 3-5min, and every 1h air replacement circulation treatment once, control the volume fraction of carbon dioxide in the chlorosis pool <3%;
[0022] b. Medium-term chlorosis treatment: After the chlorosis treatment in the storage is completed, the ethylene concentration is controlled at 2 μL / L, the inflow flow rate is 5mL / min, and the temperature of the chlorosis storage is con...

[0025] A method for segmented chlorosis of citrus, the method may further comprise the steps:
[0026] a. Storage chlorosis treatment: Spray 100mg / L anti-falling agent and 0.1% thiophanate-methyl on the surface of citrus 3 days before fruit picking. Add ethylene to the green storage for chlorotic treatment, the ethylene concentration is 6 μL / L, the flow rate is 14 mL / min, the temperature of the chlorotic storage is controlled at 28 ° C, the relative humidity is 96%, and the treatment time is 28 hours. Circulation fan is used for air circulation treatment, and the air circulation treatment is once every 5 minutes, and the air is replaced and circulated once every 1 hour, and the volume fraction of carbon dioxide in the chlorosis storage is controlled <3%;
[0027] b. Medium-term chlorosis treatment: After the chlorosis treatment in the storage is completed, the ethylene concentration is controlled to 3 μL / L, the inflow flow rate is 7mL / min, and the temperature of the chlorosis ...
Embodiment 3
[0030] A method for segmented chlorosis of citrus, the method may further comprise the steps:
[0031] a. Storage chlorosis treatment: Spray citrus with 75 mg / L anti-falling agent and 0.1% thiophanate-methyl on the surface of citrus 2 days before fruit picking. Add ethylene to the green storage for chlorosis treatment, the ethylene concentration is 4.5μL / L, the flow rate is 12mL / min, the temperature of the chlorotic storage is controlled at 24°C, the relative humidity is 93%, and the treatment time is 27h. The air circulation fan performs air circulation treatment, the air circulation treatment is once every 4 minutes, and the air replacement circulation is once every 1 hour, and the volume fraction of carbon dioxide in the chlorosis storage is controlled <3%;
[0032] b. Medium-term chlorosis treatment: After the chlorosis treatment in the storage is completed, the ethylene concentration is controlled at 2.5 μL / L, the inflow flow rate is 5.5 mL / min, and the temperature of the...
