Artificial pollination technique of apple tree

The apple tree artificial pollination what an important influence on the development of apple tree fruit, artificial pollination techniques here fruit apple pollen introduce apple tree.
First, artificial pollination: Apple flowering period is short, if encountered in the rainy season, low temperature, high winds and dry hot wind and other adverse weather, will seriously affect the pollination and fertilization. Even under good weather conditions, artificial pollination could significantly improve fruit setting and fruit quality. Therefore, even if there are enough pollination trees, it is necessary to carry out the technology of artificial pollination.
Two, flowers in cultivated varieties before flowering, pollination varieties suitable for selection, acquisition in early puberty bell, back to the room.
Three, take powder: pick up the flowers immediately take anther, the two flowers relative, rub each other, the anthers on the smooth paper, remove filaments, petals and other debris, ready to take powder. Pollen can be used for pollen pollination.
There are three kinds of methods: one is to take powder dried flour. The anthers evenly spread in smooth and clean paper, put in the 60%~80% relative humidity, ventilation room temperature 20~25 within 2 days, the anther can be cracked, from yellow pollen. Two is the Kang warming for powder. Mat cardboard etc. in the heated kang, placed on the smooth clean sheet of paper, paper placed a thermometer, the anthers evenly spread in the above, to maintain the temperature at 22~25 deg.. Generally 1 days or so. Three is the warm box powder. Find a carton (apple box, wooden box, etc.) the bottom with a clean paper or newspaper, put the thermometer, spread pollen, hanging above a 60~100 watt light bulb, bulb height adjustment, the bottom of 22~28 DEG C, after 24 hours or so to. Dried pollen, along with the anther shell, is collected in a dry glass bottle and placed in a cool, dry place.
Four, pollination: apple flower opening day pollination and fruit setting rate is highest, therefore, should be in the early flowering period, which is about 25% of the total tree flowers when they began to pay close attention to pollination, pollination in the morning from 9 am to 4 pm between. At the same time, attention should be paid to the early stages of pollination, pollination in flowering stage and full bloom stage two times better.
There are three kinds of pollination methods.
The first is the point, the old newspaper rolled into a pencil like hard paper stick, one end of the grinding into a good pencil pencil, used to dip pollen, can also use a brush or rubber head. Pollen in a clean glass bottle. Pollination pollen to be dipped in the paper sticks to the open heart gently point on the line. A dip powder can point 3~5 flower. General grant 1~2 two flower per inflorescence; pollen bag dusting. Pollen mixed with 50 times the talcum powder or sweet potato noodles, installed in the two layer of gauze bag, tied to a long pole, in the top of the tree gently vibrate, so that the pollen fall evenly. Three liquid pollination. The pollen grind fine sieve, every 1 kg of water plus pollen of 2 grams, sugar, 50 grams, urea, 3 grams, shed sand of 2 grams, with a suspension, with ultra low volume sprayer spray. Note that the suspension should be matched with the.
