There are four tricks to store chestnut

Although chestnuts are dried fruits, they are afraid of dryness, water, heat and cold, and they should not be sold after the sun. Therefore, we must attach great importance to the harvest and storage of chestnut fruit. 1. The mature chestnut shed of chestnut is harvested in a timely manner in yellow, and the top of the chest is split into "10" shapes. The chestnut fruit is brown and shiny. The chestnut harvest period varies from variety to species. Generally, early maturing varieties mature in early September, and late maturing varieties harvest in early October. Harvesting too early or too late will affect fruit quality and storage tolerance. 2, rapid sweat chestnut harvest, the higher the temperature (sometimes above 20 °C), fruit water content, high respiratory intensity, a lot of heat, if not timely "sweat" treatment, will cause the fruit rotten. Therefore, the chestnut shed harvested should be thinly spread in a cool place with a lee, and the thickness should be 20-30 cm. Water is poured every day, flipped, cooled, sweated for 2-3 days, and immediately threshed manually. 3. Fumigation and insecticide Most of China's chestnut-producing areas are seriously harmed by weevil and peach aphid and must be fumigated. After threshing, in the confinement condition, 2.5-3.5 grams of methyl bromide is applied per cubic meter, fumigation is carried out for 24-48 hours, or 30 milliliters of carbon disulfide is applied per cubic meter for 20 hours to kill pests without affecting their ability to germinate. . 4. The chestnut fruit that has been treated in the wet sand trench can be mixed with wet sand and temporarily stored in the room. Before freezing, the chestnuts were then moved to outdoor trenches for storage. Choose a ditch with a width of 1m in the shade, dig a depth of 1m, and lay 10cm thick wet sand at the bottom of the ditch. Add two wet sands and one chestnut fruit and mix well and put it in the ditch. Install it up to 20cm away from the ditch. . And in the ditch every 1 meter erected a diameter of 10-15 cm of grass to facilitate ventilation. After putting the chestnut fruit, put 10cm thick sand on it. In the end, it is cultivated to prevent the infiltration of rainwater. China Agricultural Network Editor
