Collection and storage of pollination pollen of fruit trees

In the process of producing fruit trees, usually due to fewer pollination trees in the orchard, the flowering period of wind, cold weather and the bees can not carry out normal pollination, so it is necessary to take artificial pollination measures. So, it is needed to establish the system of pollen preparation, to collect the pollen of the natural conditions in advance, and the main methods are as follows:
A pollen in the pollen collection, a large amount of high-quality fruit varieties before flowering, flower thinning can be combined with the acquisition work, bell brought to the room in early puberty to the petals, filaments removed, retaining only the anther. The anther tile to clean paper, placed in 20 degrees Celsius to 30 degrees Celsius on fire, turning once every two hours, can also be dry in a dry and ventilated place, room temperature maintained at 20 degrees Celsius to 25 degrees Celsius in the room, the taboo of sun exposure. 1 to 2 of smallpox medicine from cracking pollen, repeated use of fine sieve to sieve out pollen, the pollen collected in store. Usually kg per 10 kg of flowers can be about 200 grams of dry pollen, can be used for pollination of 0.5 hectares to 0.6 hectares of orchards. At the same time, when the bee in the orchard at the hive entrance on the outside is provided with a perforation diameter 5 mm in the powder bag, the bee into the hive can carry pollen to leave. A certain period of time for a certain period of time to collect pollen to dry, properly stored for artificial pollination.
Two, storage of pollen collected in use in addition to flowering year artificial pollination, can also be based on the needs of the production of refrigerated storage, to reserve winter greenhouse fruit tree pollination or wait until second years. Therefore, we must pay attention to the preservation of pollen. The dried pollen is usually placed in a brown glass jar is sealed, then can also use plastic bags to seal, use black paper bag, and then use the plastic bags, placed in the refrigerator for storage at 0 degrees celsius. Before using the stored pollen, the germination test should be done to identify the viability of the pollen.
