Problems solved by technology

1-Methylcyclopropene, namely 1-MCP, is an ethylene inhibitor, which has been widely used in ethylene-sensitive fruits and vegetables preservation, but the fresh-keeping application of 1-MCP is almost always carried out by airtight fumigation, which limits its use scope
There are no reports on the use of thiadizuron and 1-methylcyclopropene for preservation of melons and fruit stems

Embodiment 1

[0031] Select fresh fruit with smooth fruit surface, plump fruit stem, and bright green fruit for experiment.

[0032] Preservative solution of 1-methylcyclopropene 100mg / kg and thiadiuron 400mg / kg was prepared. Soak the crispy pear and melon fruit stems of the experimental group in the fresh-keeping solution for 1 second, and soak the control group in clean water for 1 second, then put them in a cool place to dry, and store them at room temperature.

[0033] After the crispy pear melon treated by the present invention is stored at room temperature (about 25° C.) for 2 weeks, the water content of the fruit stem is measured, and the browning of the fruit stem is counted.

[0034] Example 2

Embodiment 2

[0036] Select fresh fruit with smooth fruit surface, plump fruit stem, and bright green fruit for experiment.

[0037] Preservative solution of 1-methylcyclopropene 150mg / kg and thiadiuron 150mg / kg was prepared. Soak the emerald melon fruit stems of the experimental group in the fresh-keeping solution for 1 min, and soak the control group in clear water for 1 min, then put them in a cool place to dry, and store them at room temperature.

[0038] After the emerald treated by the present invention is stored at room temperature (about 25° C.) for 1 week, the water content of the fruit stems is measured, and the browning of the fruit stems is counted.

[0039] Example 3

Embodiment 3

[0041] Select fresh, bright green, and complete fruit stems for experiments.

[0042] Preservative solution of 1-methylcyclopropene 200mg / kg and thiadiuron 10mg / kg was prepared. Soak the fruit stems of Korla pears in the experimental group in the fresh-keeping solution for 20s, and soak in water for 20s in the control group, then put them in a cool place to dry, and store them at room temperature.

[0043] After the Korla fragrant pear fruit stalks treated by the present invention are stored at room temperature (about 25°C) for 4 days, the water content of the fruit stalks is measured, and the browning of the fruit stalks is counted.
