How to carry on liquid pollination to fruit trees

Apple, pear, plum, cherry and other fruit trees were white infertility phenomenon, especially for heavy pear. Therefore, artificial pollination to increase the fruit setting rate, yield increase effect. The last general promotion of artificial solid pollen points granted, and not easy to promote consumption. The liquid spray evenly, and pollen pollination is fast, the efficiency can be increased more than 10 times.
The method is as follows:
1 Pollen Collection
For a certain variety of pollination pollen, it should be collected from a variety of trees. The acquisition method is lower in fruit early flowering bud in early puberty. Pollen collection. The pear pollen as an example, the pale peach bud early, late bud stamens become black, these flowers are not used. By the case of flower buds in sunny days, the sun cracked (but the sun is not too strong), also can use 50 - 100 watt incandescent bulbs (light) 3 cm distant from the bud drying to crack, and then use the 60 mesh sieve sieve shaking up pollen, the germination of up to 80%, left and right the rate of pollen. If the pollen need storage, can be stored in a sealed container, the temperature can be maintained at 5 to 0 degrees C.
2, preparation of pollen liquid with sugar 250 grams, 15 grams of urea, 5000 ml water into the mixture evenly, then diluted to 5% solution after adding dry pollen 10 a 12 grams, and mix thoroughly, remove impurities with three layers of gauze filter. Adding activator when spraying boric acid: 5 grams, speader (6501) 5 ml (also available for a small fine flour instead of rapid mixing, spraying as soon as possible).
3 spraying method first to master the good spraying time. Practice has proved that in the fruit tree plants have 60% of the flower buds on the flower buds just opened, the best period for the pollination of liquid pollen. Requirements for spraying in the sunny dew dry, and the range of the crown to Huadu spray, such a setting to uniform distribution of crown. In order to save the amount of pollen, it is best to use ultra low volume sprayer. In general, the fruit spraying solution is 500 - 100 ml per plant.
