Pollination process of fruit pollination pollen

Artificial pollination is the most reliable method to improve the rate of artificial pollination, the fruit setting rate could reach 70%-80%. In the absence of a pollination tree, when the weather is bad, the artificial pollination is particularly necessary.
A variety of flowers and plants, selection
The 1 main varieties selection and affinity varieties as flowers pollinated varieties. Pollination, pollen, or mixed pollen. A flower that uses a variety of pollination, or a variety of flowers. Artificial pollination of apple or pear.
2 flowers per plant should be large, itself does not affect the yield, in the early flowering period.
Two, flowers
1 the optimum time was 2-3 days before pollination.
2 collecting bell flowers or early flowering, to edge flowers as the main.
3 general 50kg flowers, out of the anther 5kg, dried pollen 1kg, can be used for fruit period 3-4hm2 tree pollination. 1g dry pollen can point about 4000 flowers.
Three, take anther
1 flowers under the breath, can not be stacked, in a timely manner in the room to take pollen, two flowers relative to rub, the anther falls. Removal of impurities,
2 can also be used 0.25cm aperture window of the end of the yarn made of sieve, will flower in after with the palm of the hand rub, anthers in beds of paper hoods, also available from anther stripping machine.
Four, take the pollen
1 the anthers evenly spread in the white paper, baked at 20-30 degrees Celsius or fire heating, thermostat, 1-2 smallpox medicine apart from pollen;
2 can also be placed in dry and ventilated, warm, clean indoor air, time 2-3 days.
The 3 reserve prepared into vials of pollen.
Five, pollen storage
1 pear pollen stored under natural conditions 10-15d, still have vitality. Short term storage, use wax paper or bottle installed, with varieties of labels, in 5 degrees Celsius drying in a dark environment, for early removal of 1D. Long term storage, may be appropriate to dry, so that the water loss of about 10%, in the refrigerator after 5-7d in -18 degrees Celsius below freezing. Take out when needed. First before the use of pollen to determine the rate of germination.
Six, pollen extenders
1 in order to reduce the cost of pollination, to add a certain amount of filler in pollen before artificial pollination. Pear pollen filler are used Lycopodium powder and talcum powder, starch and failure of pear pollen, the failure of pear pollen and Lycopodium powder is better.
Seven, pollination methods and time
1 the artificial point is the artificial point on the flower stigma.
2 pollination each vial, a pollination device, a pollinator dip pollen continuous a few flower.
3 pollination device can be rubber head, small brush, cotton etc..
4 the whole tree has 15% flowers can start pollination, the morning of the day to be carried out for the appropriate, 15-20cm granted an inflorescence, each inflorescence a flower.
5 in order to improve work efficiency, can also be used for small duster or liquid sprayer for pollination. For saving in time and use a feather duster to roll Shoufa, at full bloom in the first row of flowers at the repeated pollination tree rolling pollen, and then moved to teach a variety of trees, up and down, and rolling with a feather duster in the flower, the pollen to the stigma.
