In 2004, a ginkgo tree was planted in front of my house, and now it is sixteen or seventeen years old.
The ginkgo tree is also mentally prepared to grow slowly, but looking at the poplar tree next to it is as thick as the mouth of the pot, it wants to hold it with one hand, and the contrast is indeed a little big!
The point is that I haven't borne fruit once yet!
Chatted with colleagues and sighed about the situation. He said, "What you planted won't be public, right?"
"My gourd is male, and your gourd is female, so when your gourd sees mine, it will not work." The dialogue between Sun Wukong and the Silver HornEd King, I have always looked at it as a joke.
I Baidu a bit, did not think that the ginkgo tree is really divided into male and female!
Ginkgo biloba is a rare tree of the Ginkgo family, Ginkgo biloba, a rare tree species left over from the Mesozoic Era, which is unique to China! Because it is a hermaphrodite, ginkgo biloba really has a "male and female" distinction.
The ginkgo tree has not borne fruit all the time, most likely because of the male tree planted with the ginkgo tree. So how do you distinguish between female and male ginkgo?
The blades are different
By looking at the leaves, we can find some subtle differences. There is a crack in the leaves of the ginkgo biloba tree, and the crack in the male ginkgo tree is relatively deep, with a crack of about two-thirds of the leaf. Female ginkgo biloba trees have much shorter leaves, usually only opening a small opening in the upper part of the leaf.
The trunks are different
The canopy is also slightly different, the male ginkgo biloba tree has a smaller angle between the branches, the branches are longer, the branches are leafy, and the whole canopy looks like a tower, staggered up and down. The female ginkgo biloba branches will grow more scattered, the angle between the trunk and the branches will be larger, the upper and lower will be more rounded, and the whole canopy will be more rounded from a distance, like a round ball.
The flowers are different
The flowers of Ginkgo biloba are unisexual, with each female flower growing solitary in the leaf axils that at first glance resembles a petiole, while the male flowers are large and distinct, inflorescence-like, many and loose. Although, Ginkgo biloba has no real flowers. The flowers we are talking about here refer to spore bulbs. This is also the most accurate way to distinguish between male and female ginkgo biloba!
Planting ginkgo biloba must first understand what the purpose is, if you are more concerned about the fruit, you must choose the right plant in the early stage! Because ginkgo biloba grows slowly, it takes about twenty years for the saplings to bear fruit. If you don't pay attention, it won't be useful to be upset when the time comes, right?
How to make ginkgo trees produce earlier results
Ginkgo biloba, also known as the Gongsun tree, grows slowly. After planting the tree, it is not until he becomes a grandfather that he can bear fruit.
Under natural conditions, it takes about twenty years from planting to fruit, and a large number of fruits need to wait for thirty to forty years.
How many twenty and forty years of life are there? The fruit cycle of ginkgo biloba is really a bit long, so how can we make ginkgo biloba bear fruit early? Agronomists have long given the solution - grafting!
Through artificial methods, the maternal tissue of the fruited ginkgo tree is taken as a donor, grafted to other ginkgo trees, to achieve the purpose of allowing the recipient ginkgo tree to bear fruit in advance or improve the tree species, and the living acceptor ginkgo tree after grafting is called a ginkgo grafted tree. Grafted ginkgo biloba trees generally begin to bear fruit in three years. This makes the name of the grandfather tree "unworthy of its name".
Grafting, generally choose plants of the same family to do rootstock so that it is easy to survive. And ginkgo is the only genus of the ginkgo family, its rootstock basically has no choice, can only be ginkgo!
Common methods of ginkgo grafting are subcutaneous grafting, splitting method, cutting method, bud jointing method and so on. The specific method of Baidu, I will not introduce it here. Gardeners, themselves. The seedlings planted by their own families and married by the buyers will save time and effort.
Moreover, most of the grafted ginkgo bilobas are selected from the fruiting plants for grafting, so there is no need to worry about the problem of male and female!
