Lily sand storage has a good value-added effect on fresh-keeping.
Lily is a dual-purpose health product of medicine and food, which has the effect of moistening the lungs and relieving cough, clearing the heart and calming the mind. In recent years, more and more people eat lilies, and their fresh products sell very well. However, due to the lily mining period in the first and middle of August, when the temperature is high, the newly collected fresh products are heavy in moisture, exuberant in breath, and easy to mildew if they are not kept well. This paper introduces a method of storing lilies with fine sand, which can keep the lilies fresh for more than half a year. The storage period can not only maintain the original flavor, but also sell at a good price in New Year's Day, Spring Festival and other festivals.
1. Treatment of raw materials before storage. Freshly harvested lilies should be placed in a shaded place to avoid sunlight to prevent discoloration and loss of water from the outer layer of phosphorus. After the lily bulb is dug, the soil, stem and fibrous root should be removed in time, and then the complete lily bulb with white, large, fresh and disease-free bulb should be stored.
2. Operating points of the sand storage method: ⑴ builds a buried pool or pit with bricks in a cool house or basement, depending on the number of lilies stored. ⑵ evenly spread 6-8 cm thick fine sand at the bottom of the pond or pit, then arrange the fresh lily bulbs on the sand, then cover them with 3-4 cm thick sand, and finally discharge a layer of lily bulbs on the sand layer, stacking them repeatedly, with a stack height of 1 m, and the sand covered with lilies should be slightly dry, so as not to cause lily rooting and decay due to high humidity. ⑶ is covered with soil (or sand or straw) on the top around the lily, with a thickness of 20-30 cm, not too thin, otherwise it is easy to dehydrate the lily bulb. The storage temperature in the ⑷ reactor should be 6-10 ℃, which should be checked frequently during storage to avoid heating and mildew of lilies in the pile due to misoperation. In case of fever, the lilies should be re-stored according to the above-mentioned method.

Several main diseases on lily
The main results are as follows: (1) Lily leaf blight, also known as lily gray mold, is a common disease. It mainly harms leaves and can also infect stems, buds and flowers. The disease spot on the leaf is round, oval, of different sizes, light yellow to light reddish brown, waterlogged. Under warm and humid conditions, the disease spot becomes thin and brittle, light gray and translucent, which can cause the whole leaf to die; the stem becomes brown or constricted, resulting in the collapse of the plant; when the young plant is infected, the growth point of the stem and leaf becomes soft, rot and die; the flower bud appears small brown at the initial stage of damage.

How to select and prepare land for Lily
Lily is a semi-negative plant, which likes warm and humid climate and can grow in cooler areas. Ability to withstand drought, cold resistance, fear of waterlogging, avoid continuous cropping. The cultivation land should choose sandy loam or humus soil with high dryness, sunny, deep soil layer, loose soil and good drainage, while the mountain area can choose sparse forest or wasteland with half shade and half sun. Before sowing, 2000 kilograms of rotten barnyard manure and 20 kilograms of calcium superphosphate were applied per mu, with a depth of 25 centimeters and 30 centimeters, raked flat and fine, making a border 1.2m wide and a good drainage ditch all around.
