Peach is a tree species with high self-cultivation rate. However, abnormal climates such as low temperature, rain, and frost all have an adverse effect on fruit settling. Artificial pollination can effectively increase the fruit setting rate and promote the regularity and enlargement of fruits. . The selection of pollination varieties often involves the selection of varieties with large amounts of flowers and flowering stages. When gardens are established, they are planted with mixed varieties of various varieties or with a ratio of 1:5. Artificial pollination is generally performed in the following manner: First, take the pollen Peach anthers were collected using the following simple method: 1 to 2 days before the initial flowering period, the flowers of the pollinated varieties collected were placed on a smooth, painted table, and the flowers were gently rubbed by hand and then sieved to obtain the anthers; The 0.25 centimeter aperture of the iron screen holds the flowers, the screen is covered with a smooth white paper, and then the flowers are gently rubbed by hand, and the anthers leak onto the white paper. Although some anthers were wasted using the above method, the tests showed that the anther loss rate was generally lower than 20%. Compared with taking the anther from the flowers, the efficacies increased by several dozen times. Second, pollen processing methods There are natural drying, fire drying and electric drying. Anther should pay attention to the problem of drying: (1) temperature: the temperature is too high then the germination rate is low, the amount of powder is less; too long is a long drying time. The suitable drying temperature is 20-25 °C, and the required temperature is relatively stable. (2) Time: In the maintenance of 20-25 °C temperature, the drying time is generally about 36 hours. (3) Avoid exposure to pollen in the sun: dried pollen germination rate is only 10-20%, while the drying, drying pollen germination rate of up to 50%. Third, the storage of pollen The pollen obtained is not used for pollination in the same year but if it remains, it can be refrigerated to prepare pollination of fruit trees in winter greenhouses or reuse in the coming year. The pollen is generally sealed in a brown glass bottle; it can also be sealed in a plastic bag, wrapped in black paper, and then packed in a plastic bag and stored in a refrigerator below freezing. When used, germination tests are required. The pollen stored by this method can have a viability of more than 70% after 1 year. Fourth, artificial pollination During the flowering period, the collected pollen was made into a urine and pollen solution and sprayed with a sprayer. Sugar and urine pollen solution formula water 5 kg + 10 grams of pollen + urea 10 grams + borax 5 grams + 100 grams of sugar + a little sticky agent mix Serve. Or flowering spray 10-20 mg / kg of anti-dropping agent (PCPA) and after-spray 20 mg tea acetic acid, etc. can increase the rate of fruit set. It is also possible to incorporate pre-prepared pollen into talcum powder or milk powder in a ratio of 1: to 5-10, rub it with a rubber head, or put it in a gauze bag and shake it on the tree to sprinkle pollen. For pollination, pollination from the top of the crown, the crown to the crown. Repeated 3-4 times at flowering stage can significantly increase the fruit setting rate. Fifth, the use of bee pollination In the orchards with more than 20% pollination and evenly distributed, wall bees or bees can be released at flowering stage, which can significantly increase the fruit setting rate. Pollination of wild bees and fork wall bees, after testing, the pollination effect is better, and the fruit set rate in Taoyuan can be increased by 11%. The method is to remove the bee sting from the 4-5°C refrigerator or fruit store 3-5 days before flowering of the peach tree and put it into the prepared honeycomb tube. Each honeycomb tube is equipped with a bee sting, and the head of the bee sting is headed. The spout and the spout are sealed with thin toilet paper so that the bees can emerge from the nest. The hive tube (50 bundles or 100 bundles bundled) is then hung near the south wall of the orchard care room and around the recovery nest tube for recovery. 50-70 heads of bees are placed per acre.
