Method for making artificial pollination pollen

There are two main methods to produce pollen in the conventional artificial pollination:

(1) artificial powder: hands each holding a flower, flower relative friction, the anther and filament, petals entire wipe onto the paper, clear petals and anther filaments, thin stall on the paper, 25 degrees C, indoor air, usually takes 28-48 hours to shed pollen anthers cracking.

(2) take the powder machine for powder: dereagent machine from anther, sift the petals, pedicel and other debris, and then spread in the thin anther smooth white paper, placed at 2325 DEG C in the greenhouse after 2840 hours of shade, that the amount of pollen shed. Using the above method to produce pollen generally takes 2-3 days to complete. This method solves the problem of artificial pollination of Pear under normal circumstances, the abnormal weather, pollination varieties collocation and other special circumstances, such as the time of flowering and pollination varieties cultivated varieties are early flowering varieties or time of flowering pollination varieties is the flowering period, the general need 2-3 days to complete pollen plus, which will lead to the first flowering varieties due to the production of pollen is not timely without artificial pollination and production; and in the pear tree planting, first flowering pollination varieties is one of the main cultivars (general pollination varieties and cultivar 1:4, some as high as 1:1), the yield of total yield for pollination varieties pear cultivation is very important. Nowadays, natural disasters are becoming more and more frequent, and the threat of climate factors to agricultural production is increasing. In recent years, there are different pear producing areas in China each year. Aiming at this problem, domestic and foreign experts have carried out relevant research of pear, 2006 Wang Ling, Zhang Shaoling studied the effects of storage temperature and humidity on pear pollen viability, the results show that under dry conditions, the lower the storage temperature, the pollen viability decreased more slowly, the longer the storage period. Feng Shui pear pollen at _73 degrees -196, C degree C can save the life force for a long period of time. General pear pollen germination was more than 55% belong to high-quality pollen cryopreservation after 540 days, the pollen germination rate was more than 60%, can meet the production requirements on pollination. However, through this method to preserve the pollen, high cost and high technical requirements for the preservation of personnel, the current technology is in the stage of scientific research, the general farmers and companies are difficult to grasp and use.
