The method of harvesting and storing fresh chestnut by stages

Fresh chestnuts contain a lot of water, sugar and starch. Improper harvesting and storage can easily lead to decay or insects.

1. Harvest chestnuts in three batches according to the age of the fruits. When the fruit and grape peel separate (i.e. explode), shake the saplings with your hands to make all mature fruits fall. The big tree must climb up the tree and shake the ripe fruit over the branches. Usually, harvest once every morning and evening. This can improve the quality and yield of fruits, prevent the branches and leaves of chestnut from breaking, and is conducive to high yield and stability.

2. Safe storage: (1) wet sand mixing method: use wet medium coarse sand with a moisture content of 8% - 10% (the chestnut content is more than 2-3 times the stored chestnut content), and then mix it with fresh chestnuts and put it into the altar. Put more sand on the surface, cover the mouth of the altar with straw, and then put it on the ground. Later, pour it out and check it. Take out the black chestnuts and put them into the jar. When there are more chestnuts, you can also put them in the room. Store the mixed sand in a ventilated place (the stacking height shall not exceed 60 cm) and cover it with film or straw. Pay attention to rolling and moisturizing, so that the chestnut water is even and safe to store. (2) Mixed storage method of sawdust: sawdust should be fresh with water content of 30% - 35%. For example, dry sawdust can be moistened with water. There are two storage methods: one is to mix the whole fresh chestnut with sawdust. Put it in a box (bag), cover it with 8-10 cm thick sawdust, and put it in a cool and ventilated place. The other is in a cool and ventilated room. Enclose a box 1 meter long and 40 cm high with bricks. Put 5 cm thick wood chips, then mix chestnuts and wood chips in the ratio of 1:1 into the box, and cover with about 10 cm thick wood chips.

3. Natural air drying method: remove pests and diseases and damaged fruits, spread them out for 1-2 days, let the water evaporate, soak an appropriate amount of fresh fruits in a bucket of cold water for 7-8 days, and the fruits will be reduced by about 10%, then take them out, put them into bamboo blue medium, hang them for ventilation, and make them dry naturally. The first month of storage is a dangerous period. After frequent inspection, if you choose this method to save until the next April, the chestnuts are still fresh.

4. Storage of spiked buds: when the spiked buds of chestnuts are broken by about 30%, remove the mature spiked buds with yellow shells and put them into containers. Cover the top with a little white grass and let it adapt to a period of time in a barn or a dry, ventilated and cool room. No chestnuts. When you need to eat, remove the thorny buds together, so that you can save them until next spring. At first, the whole tree is still fresh, but it is necessary to prevent it from sprouting after spring.

The above is the method that fresh chestnut needs to be harvested and stored in several times.
