Key points for storage of lily seeds

Due to the arrangement of stubble, the harvest time of lilies is not consistent with the sowing time, and the lilies that need to leave seeds should be preserved for 30 ~ 50 days before sowing. In order to prevent lily from being harmed by diseases and insect pests, mildew and deterioration during storage, the following key points should be grasped in lily storage.

One is to choose a sunny day to harvest before and after the End of Heat (August).

Second, the lilies used to store seeds must be fully mature, low water content, disease-free, insect-free and damage-free. When picking up the ball and loading the basket, remove the stalk, remove the soil, cut off the fibrous root, handle it gently, load it into the basket by stages, and hide the light in time, and transport it back to the room to prevent the sun in the field, so as to prevent the outer scale from becoming red and dry, deteriorating the quality and affecting the germination rate.

The third is to select the bulb with enlarged mother bulb, consistent uniformity, white color, close cohesion, strong root system, flat and round top, intact bract mouth, no disease, no insect injury, no peculiar smell, no rotten pieces, many and stout lower roots, and clear sac division (each bulb has three or four bulbs). Rootless bulbs should not be reserved for seed.

The fourth is to carry on the chemical treatment to the seed ball. The seeds were soaked in chlorothalonil and triclofenac EC for 20 ~ 30 minutes and then preserved after drying. The storage place should grasp the principle of "drying, aeration, shading and shading". Choose an empty room and fumigate with 0.3% formaldehyde and potassium permanganate once. Do not put the seed ball on the cement floor.

The fifth is to adopt the stacking method, laying a layer of clean loam 7 cm thick on the ground (hand-pinched into a ball, loose on the ground) or dry fine river sand, usually three or four layers can be piled up, the first layer of roots facing down, neatly arranged, and then covered with a layer of soil or sand about 4 cm thick, with a layer of lily on top, the root system facing up, and then a layer of soil or sand, and so on, it is appropriate to cover the soil or sand thickness without exposing lilies, and the surrounding soil or sand is tightly sealed. It can be stored until the following spring. During the storage of lily, a dry and wet thermometer was installed in the storage room to control the temperature and humidity and improve the ventilation condition. Check every 20 to 30 days, should not turn too much, if found necrotic lily bulbs, should be removed in time.
