Bagged ditch storage technology of planting pomegranate

First, dig trenches to dig storage ditches in a flat, cool and clean place. The ditch is 80 cm deep and 70 cm wide, and its length depends on the amount of storage. Three to five days before fruit harvest, the storage ditch was dug, and the ditch mouth was tightly covered with grass stalks during the day and opened at night, so that the temperature in the ditch was basically consistent with the low temperature at night, so that the ditch could be harvested and bagged for storage.

Second, bag the ripe fruit, harvest it in the morning on a sunny day, soak it with preservative (100 times D7 antistaling agent) solution for 10 minutes, then put it into a non-toxic plastic bag with a thickness of 0.04 mm, a width of 50 cm and a length of 60 cm, each containing 20 kg. After bagging, fold the mouth of the bag and put it into a fruit basket or fruit box lined with a bushing bag. Cover with the basket or box cover, not closed.

3. In the early stage of temperature storage, the trench was covered with grass grass during the day and opened at night, so that the temperature in the storage ditch should be controlled at 2 ℃-3 ℃. In the middle of storage, with the continuous decrease of natural temperature, when the temperature in the storage ditch dropped to 0 ℃, the mouth of the plastic bag was tightly fastened, the basket or box was covered, and the storage ditch was tightly covered with 2-3 layers of grass, and checked once a month. In the later stage of storage, when the air temperature rises in the first and middle March and the storage temperature in the ditch rises to more than 3 ℃, the management in the early stage of storage will be restored, and the natural low temperature at night will be used to reduce the temperature in the storage ditch and prolong the storage period.

The storage method is simple and easy, and the pomegranate fruit can be stored until the end of April or early May of the following year, the fruit is still bright, bright and fresh, and the rate of good fruit is more than 92%.
