Harvesting and Storage of Lily bulbs

1. Seed ball mining when the temperature begins to drop in autumn, the aboveground stem has begun to die, and the mother ball develops to a certain extent, the seed ball is dug in sunny days. Before digging, the dead stems of the aboveground must be extracted and burned centrally, so as to reduce the pathogen. At the same time, pay attention to mining do not damage scales, or remove damaged scales, in order to reduce decay. 2. The treatment of seed balls before storage the seeds should be graded, cleaned, disinfected, packaged and so on before storage. The main results are as follows: (1) generally speaking, the larger the bulb of lily, the more the number of flowering, and if the bulb is small, the number of flowering is less. Therefore, the classification of planting balls is beneficial to planting trees separately and is easy to manage. After mining, it is necessary to separate the big and small seed balls, and the standard of classification is that the mother balls are in a group and the daughter balls are in a group. At the same time, pay attention to the following aspects: if the scales are found to be rotten, they should be removed in time. If the perimeter of the bulb is about 12 cm, it can be used for cut flower cultivation. Small bulbs that have sprouted or grown new roots can be cultivated immediately, do not damage new roots and buds. The large bulbs with new roots should be grouped into one group, which could not be treated at low temperature at-2 ℃. (2) it is decided whether or not to clean the seed balls that have been dug depending on the amount of soil in the belt. Those with more soil can be cleaned. It is not necessary to clean the seed balls planted in sandy loam if they are dug in sunny days. The removal of much soil is beneficial to the disinfection treatment before storage and to the elimination of diseases and insects in the soil. (3) the seed bulb should be disinfected in order to prevent and cure virus disease, rot disease and leaf spot disease. Disinfection treatment is generally carried out 1-2 times, the first time before the seed ball into the cold storage, the second time after the seed ball out of the cold storage, before planting. If it is long-term storage, that is, 8-12 months, it is necessary to carry out the above secondary disinfection treatment; if it is short-term, that is, within 8 months, only the first disinfection treatment can be carried out. (4) Packaging should be packed before storage in order to facilitate the management of the storage period. The package is a plastic film (0.22%) after strict cleaning and disinfection. The plastic film should be punched 14-18 holes for ventilation. In addition, fillers with a certain water content must be used. Wet sawdust or moss can be selected. Attention should also be paid to strict disinfection of fillers. The packing method is to first put the plastic film into the box, then put a layer of filler at the bottom of the box, its thickness is 5 cm, put a layer of seed ball on the filler, and note that the same layer of seed ball must be separated by the filler. after the box is full, close and fasten the plastic film. 3. Storage of lily bulbs after harvesting, in order to achieve annual flowering, low temperature treatment and storage must be carried out.
