Judging from the chestnut fruit maturity, the harvesting period of chestnuts: the best harvesting period is when about 1/3 of the chestnut buds of the whole tree crack naturally.
When harvesting, avoid rainy days, the first clear weather after rain, or the time when the morning dew is not dry, otherwise the harvested chestnuts are perishable. In production, the chestnuts are harvested after several consecutive sunny days. The chestnuts harvested in this way have bright skin, full body, low water content, good quality, not perishable, and storage and transportation.
Chestnut harvesting method Picking up the chestnuts on the chestnut tree naturally matures and cracks, and pick up the nuts after they fall to the ground. The chestnuts harvested by this method are well-developed, beautiful in appearance, shiny, good in quality, durable in storage and transportation, and can also make full use of auxiliary labor. But it must be picked up every day, otherwise the chestnuts will be exposed in the ground for a long time and will lose water and air dry, which will affect the yield and fruit quality. According to experiments, chestnuts are exposed under the tree for 1 day, and the weight loss of water reaches more than 10%, and the chestnuts after loss of water are very prone to mold and rot during storage and transportation.
If the chestnut is cracked by more than 40%, use a bamboo pole to shake the chestnut off, and pick it up and place it in the shade. Spray a small amount of water on each layer 20 cm to increase the humidity in the pile. The thickness of the pile is not more than 80 cm. After 5-7 canopy buds crack, pick out the chestnuts, taking care not to damage the smoothness of the peel. For convenience and speed, some chestnut farmers use wooden sticks to hit the buds after the chestnuts are cracked, which seriously damages the waxy luster of the peel, and even scratches, which will greatly reduce the grade of the fruit.
