Embodiment 1

[0014] Pick in the morning or evening on a sunny day, select 100kg of peppers with no skin spots and no mechanical damage, pre-cool to 12°C at 10 hours, and put them in 5m 3 Fumigated with 2.5mg of 1-methylcyclopropene in a plastic shed for 8 hours; then divided into 20 packages according to 5kg / pack with 0.01mm thick plastic wrap, and added 1 bag of CT- 6 Special antistaling agent for peppers, then put it into a constant temperature warehouse with a temperature of 12°C and a relative humidity of 90% for 90 days, and make the CO in each bag 2 with O 2 Concentration is 5%, its Vc content is measured to reduce to 92mg / 100g from 105mg / 100g when picking, little change, spoilage rate 9%, dehydration rate 1.5%, suitable for long-term storage and long-distance transportation.

Embodiment 2

[0016] Pick in the morning or evening on a sunny day, select 100kg of peppers with no lesion on the skin and no mechanical damage, pre-cool to 10°C in 24 hours, and put them in 5m 3 Fumigated with 7.5mg1-methylcyclopropene in a plastic shed for 12h; then divided into 33 packs with 0.03mm thick plastic wrap according to 3kg / pack, and added 2 bags of CT- 6 Special antistaling agent for pepper, then put it into a constant temperature warehouse with a temperature of 10°C and a relative humidity of 95% for 80 days, and make the CO in each bag 2 with O 2 The concentration is 2%, and its Vc content is reduced from 105mg / 100g to 102mg / 100g when picking, with little change, the spoilage rate is 3%, and the water loss rate is 1.1%, which is suitable for long-term storage and long-distance transportation.

Embodiment 3

[0018] Pick in the morning or evening on a sunny day, select 100kg of peppers with no lesion on the skin and no mechanical damage, pre-cool to 9°C at 15h, and put them in 5m 3 fumigated with 5 mg of 1-methylcyclopropene for 10 h in a plastic shed; then divided into 25 packs with 0.03 mm thick plastic wrap according to 4 kg / pack, and added 1 bag of CT-6 purchased from the National Agricultural Products Preservation Research Center to each pack. Pepper special preservative, then put it into a constant temperature storehouse with a temperature of 9°C and a relative humidity of 93% for 70 days, and make the CO in each bag 2 Concentration is 4%, O 2 With a concentration of 5%, its Vc content is reduced from 105mg / 100g to 98mg / 100g when picking, with little change, the rate of spoilage is 6%, and the rate of water loss is 1.3%, which is suitable for long-term storage and long-distance transportation.
