Ginkgo artificial pollination to do "five attention"

In order to improve the quality of artificial pollination of Ginkgo biloba, “five attentions” should be achieved during the pollination process: First, pay attention to the quality of male flowers. Whether it is collected by oneself or purchased on the market, we must use high-quality male flowers that are yellow in the green and bright in color. Never use over-male, moldy, dark, and outdated male flowers. The second is to pay attention to master the best pollination period. According to the prediction of the Municipal Forestry Bureau, the best pollination time for this year is April 15 to April 17. On this basis, the majority of fruit growers should pay attention to the observation of the spitting water of the female ginkgo trees. The maturity of female flowers of different ginkgo trees at different ages and in different locations is inconsistent. Do not follow the flow and follow others. Third, pay attention to the control of pollination. Adhere to the principle of "full trees and half trees and full trees and half trees." Generally, one hundred pounds of white fruit (nuclei) are used with three male and two male inflorescences. The specific dosage should consider the growth and age of the tree. Fourth, we must pay attention to the impact of weather. During pollination, in case of floating dust and sand and dust weather, female flowers should be rinsed with clean water first, and then pollinated. If it rains after 6 hours of pollination, it should be given in time after the rain stops. Fifth, pay attention to pollination apparatus clean and non-toxic. Before pollination, rinse the pollinator repeatedly with clean water to make it clean and non-toxic. The pollen solution must be used with the water for no more than 2 hours.
