Management skills of kiwi fruit before and after harvest

Kiwifruit has a unique flavor, sweet and sour taste, and is deeply loved by consumers. However, the timing of the picking is exquisite. Picking too early will seriously affect the taste of kiwifruit.

1. Harvesting standards

In my country, the soluble solid content reaches 6.5% as the lowest index for harvesting. If the storage period after harvest is longer, the soluble solid content reaches 7.5% before harvesting, so that the storage performance, shelf life and soft ripening of the fruit The flavor quality is better.

2. Harvest in time

There are many varieties of kiwifruit. The period from flowering to harvest is generally 140-150 days. The fruit growth period between the varieties is very different. The maturity period starts from August to the end of October. Early-harvested kiwifruit has little nutrient accumulation, sugar content and acidity are not up to the standard, and loses the original flavor of the original variety after soft-ripening; the starch content is high, and the transformation process is easy to change flavor. Fruit picking should be carried out in the morning and evening when the weather is clear, cool in the evening, or in cloudy weather, and avoid harvesting at noon and high temperature, otherwise the fruit will absorb a lot of field heat and not dissipate, which will easily accelerate the softening of the fruit. Harvested when the fog and dew are not dry, the fruit surface is moist, which is good for pathogen infection.

3. Take off the bag before harvest

Bagging kiwi fruit should be bagged 5-7 days before harvesting, so that the surface of the peel will increase in the sun to avoid the appearance of whole green fruits, and at the same time, it can increase the sugar content of the fruit and improve the quality of the fruit.

4. Harvesting method

When picking the fruit, hold the fruit with your hands, press the stalk with your fingers lightly, and break it close to the fruit. Take it gently and try to avoid stabbing, crushing, and bruising. To avoid damage caused by fruit picking, fruit pickers should cut their nails short and smooth, wear soft gloves, and use wooden boxes and fruit baskets with soft bedding to avoid fruit bumps. Fruit harvesting should follow the principle of "down first, then up, first outside and then inside", that is, start from the periphery of the lower part of the canopy, and then pick the fruits from the inner chamber and the upper part of the canopy.
