Fresh-keeping storage method of mulberry leaves

The invention discloses a mulberry leaf fresh-keeping storage method which comprises the following steps: 1) picking mulberry leaves, placing the picked mulberry leaves in a leaf picking basket, and then placing the picked mulberry leaves in a transition area of 15-25 DEG C for temperature buffering; and 2) wetting a substrate by using a fresh-keeping solution, placing the wetted substrate in a storage device, inserting the petioles of the mulberry leaves subjected to temperature buffering in the step 1) into a working substrate, enabling the petioles to face downwards and the leaves to face upwards in a vertical state, and performing low-temperature preservation, thereby realizing fresh-keeping storage of the mulberry leaves. The mulberry leaf fresh-keeping storage method objectively facilitates operation of silkworm feeding personnel, effectively improves silkworm feeding work efficiency, fundamentally prolongs mulberry leaf fresh-keeping storage time, greatly avoids mulberry leaf yellowing and mildewing an
