Detailed Explanation of Lily Harvesting and Storage Methods
Currently it is lily harvesting season. When all the aboveground stems have withered, it indicates that the bulbs have matured and can be harvested. For harvesting lilies, choose a sunny day, and dig gently to avoid artificial damage. After the lilies are dug up, promptly cut off the stems and fibrous roots, and remove all soil. When filling baskets, pack those kept for seed separately from those not kept for seed, pack large bulbs separately from small bulbs, and healthy bulbs separately from diseased bulbs, transport and store them separately, and make sure to handle, place, and pack them gently, transport them indoors in time, spread them in a thin layer to air, and cover with straw to avoid light, so as to prevent strong direct sunlight from causing the outer scales to dry out and discolor, affecting their appearance and reducing their commercial value. Only after sweating for a few days can they be stored.
After lilies are harvested, apart from being supplied for direct market sales and processing, the rest need fresh-keeping storage to ease the contradiction between market supply and demand. Lilies kept for seed especially need fresh-keeping storage to maintain seed bulb quality and increase the germination rate. The main method of fresh storage for lilies is the sand storage method. Lilies for fresh storage are required to be fully mature, low in water content, disease-free, insect-free, and scar-free high-quality bulbs. Next, choose a dry, ventilated, light-proof cellar or room, first fumigate and disinfect with 0.3% formaldehyde and potassium permanganate, then spread a 5-7 cm thick layer of fine sand on the ground, place the lilies (upside down) on it, then cover with 3-4 cm of fine sand, and then in turn place another layer of lilies and another layer of fine sand... The total height should not exceed 100 cm. Finally, cover the surroundings and top of the lily pile with 20-30 cm thick sand. The sand used for fresh storage of lilies should be on the dry side; if too wet, the lilies will root and become moldy and rotten. During storage, check once every 20-30 days, and promptly remove any lilies found to have gone bad.
