Artificial pollination of kiwi fruit
Recently it is our kiwifruit orchard in Xi 'an Glair is the most beautiful time of the year, far away you can smell the fragrance of flowers and a large white flowers, but this is also our most busy time, everyone is busy to bloom flowers for artificial pollination, to ensure the quality and yield of kiwifruit.
Kiwifruit is dioecious fruit trees, and the flowering period is short, such as inadequate pollination or pollination is not timely, will directly affect the quality and yield of kiwifruit, reduce the marketability. Therefore, the pollination of kiwifruit is very important, and sufficient pollination technology is one of the key technologies to improve the quality and efficiency of kiwifruit. Kiwifruit pollination is divided into insect pollination and artificial pollination, the current production of artificial pollination, insect pollination as the assistant.
Insect pollination: There are many insects available for kiwi pollination, but bees are the main ones. Pollinators such as wall bees and bumblebees can also be released artificially. Pollination by bees requires a large number of bees, to 5 ~ 10 mu of land put a box of bees is appropriate, each box has no less than 15 ~ 20 thousand vigorous bees. Move the hives into the garden when about 10% of the female flowers are in bloom. Place them in a sunny part of the garden. Feed each hive 1 l of 50% sugar water every 2 days to increase the bees vitality.
Artificial pollination: female kiwifruit flowers can be pollinated and fertilized within 5 days after opening. Generally, the pollination effect is the best in 1 ~ 2 days after opening. On the 4th day, the pollination rate decreases, the seed number in the fruit decreases gradually, and the fruit size becomes smaller.
Pollination: Collect the male flowers that have just opened in the morning, place the petals upward on the plate, and gently smear the stigmas of the female flowers with the stamens of the male flowers. Each male flower can give 7 to 8 female flowers.
Pollen collection and pollination: pollen collection, extraction and storage. Collect the male flowers that are about to open or semi-open in time before 8 o 'clock every morning, and remove the toothbrushes, scissors, tweezers and so on. The anthers were spread flat on the paper and placed at 25 ~ 28℃ for 20 ~ 24 hours to make the anthers crack and disperse pollen. Or put the anther in an incubator, waiting for the pollen to disperse; Or cover the anther with a layer of newspaper and put it in the sun to depowder.
If the amount of orchard pollen is insufficient, or it rains, powder is difficult to collect, you can choose high-quality pollen produced by regular manufacturers, generally 10 grams of pure pollen per mu of fruit orchard.
Pollination with simple pollinator: the pollen is diluted 5 to 10 times with talc powder or lycopodium seed, put into a thin plastic bottle with a rubber cap, insert a thin bamboo stick on the bottle cap, and press the bottle with your hand to generate air to blow the pollen to each stigma.
Due to the large scale of our planting macaque peach garden, it is difficult to ensure the best pollination effect of natural insect pollination affected by environmental weather and bloom time, so we need to complete the pollination work with quality and quantity.
