How to improve the pollination quality of apple trees?

Pollination quality of apple trees directly affect the apple tree fruit, so as to improve the quality of pollination of apple trees, is to improve the yield of the premise! How to improve the quality of pollination trees? Don't be anxious, to cultivate fruit pollen network to weapon, in order to improve the quality of apple tree pollination.
1, according to the standard configuration, scientific selection of pollination varieties
In order to ensure the quality of the fruit and the steady production in recent years, the proportion of the general pollination tree should be 20% ~ 25%, that is, from 4 to 5: more reasonable, the minimum should reach 15%. The pollination tree configuration, the main varieties should be considered to be, we must adapt to the local environment, but also consistent with the main cultivars of flowering, pollen quantity, good affinity.
2, flowering bees
The effect of insect activity on pollination efficiency and fruit setting rate. General 5 ~ 10 acres of orchards placed between 1 ~ 2 boxes of bees or separated by a wall hanging from the wall of 50 ~ 60m, with a total of about 100 per mu. 2 to 3 days before flowering, the bees were placed in the field. In December, it was taken out of the nest tube to take out the cocoon, and put it in a clean jar. It was stored at room temperature in the following year. In February the following year, the bees were kept at 0 to 5 degrees. Wall bee pollination per acre garden only 80 ~ 100 wall bee. To keep bees in the pit when the semi - water and semi - mud state, so as to provide material for wall bee nesting. During the release of bees, it is strictly prohibited to spray pesticides in the orchard; to prevent the wind and rain to wet the hives and cause the death of the young bees; to prevent ants, spiders, birds, etc..
3, artificial pollination
At low temperature, rainy weather, wind, dust and other adverse weather, will directly affect the insect activity and natural pollination; pollination varieties configuration quantity is small, uneven, or with varieties of flowering, will greatly reduce the rate of fruit. In the purchase of goods or in combination with pollen, collected many varieties of flower bud thinning stripping, dry pollen in blooming stage (the flowers open in the morning 8:00 - 10:00) artificial points granted or liquid (water spray "10 kg+ pollen 10 ~ 20 g) the center of flowers, can effectively reduce the deviation of fruit rate, high fruit setting the rate of 50%.
4, spray nutrient solution
Early morning, flowering 8:00 10:00 spraying nutrient solution (water or honey 100 kg+ sucrose 1 kg+ 0.3 kg+ 100 g borax flower), can also be at full bloom spray 1 times 0.2% ~ 0.3% or 0.05% ~ 0.1% Yiguoling rare earth fertilizer can significantly increase the fruit setting rate, promote fruit development. In addition, early flowering and flowering period of 0.1% ~ 0.3% spray borax (boric acid), or 500 to 1000 mg/kg rare earth fertilizer can improve the quality of pollination and fertilization, so as to ensure fruit.
