1. Potatoes harvested after harvesting should be carried away in their fashion bags. They should not be placed on exposed grounds, and should not be covered with diseased yam, or sun-covered without cover. Otherwise, potato rot inside the potato heap and external potato skin will turn green.
2. There must be order in order to receive crops. Generally, crops are harvested first and then crops are harvested. Strictly distinguish bagging, separate placement, avoid mixing.
3. The loading should be lightly loaded and unloaded to avoid massive abrasion of the peel or tuber cracking.
