Many of our farmers and friends in the countryside often plant so many kiwi trees behind the front house or in their own small yards, but many people often ask the agricultural technology basket: Why my family's kiwi fruit has been planted for many years, although it blooms every year, but it is not fruitful, it is really angry to death! There are also some friends who like to plant flower seedlings, after planting the kiwi tree they bought back, the careful management of good fat and good water every year, after a few years, the tree grows very luxuriantly, but the eyes can't expect the fruit on the tree!
In fact, this kiwi fruit does not bear fruit, on the one hand, because you may only plant a male tree that will always flower and never bear fruit, on the other hand, although the kiwi fruit you plant is a mother tree, if you only plant a mother tree and do not plant a public tree on its side to give it flowering and pollination, it will not bear fruit.
Because, experienced friends know: kiwi fruit trees are divided into male trees and mother trees, male trees are responsible for pollinating the mother tree after flowering, and the mother tree is responsible for accepting male powder after flowering, and if the kiwi fruit can flower and bear fruit, we generally need the male tree and the mother tree to be planted together when planting, and a single kiwi fruit tree cannot bear fruit.
Seeing this, many people may say: agricultural technology small back basket, I want to plant kiwifruit, but when buying saplings do not know how to distinguish and judge whether it is a male tree or a female tree? The kiwi fruit I grow at home has been growing for many years, but it has not borne fruit, how can I identify and judge whether it is a male or female tree?
Don't worry, today the agricultural technology basket will tell you: how to clearly judge and accurately distinguish the male and female trees of the macaques? I believe that after you read it, just verify the kiwi fruit tree in front of you to ensure that you will understand and learn at a glance, which is simple and does not delay the work. The specific methods of discernment and judgment are as follows:
A look at the tree shape
Kiwi trees and female trees are different in the overall appearance of the plant, we can observe the characteristics of the shape of the plant to determine whether the kiwi tree is a male or female tree during the growth period of the fruit tree.
Judgment method: In general, in comparison, the male tree of kiwifruit generally grows more compact in the shape of the tree, and because it is only responsible for flowering and powder, not responsible for the fruit, so the kiwi tree in the orchard is generally rarely pruned or pruned relatively rough, and the tree shape will appear more chaotic and invisible; and the mother tree of the kiwi fruit generally grows looser in the shape of the tree, and for the number and quality of the mother tree, the mother tree in the orchard generally needs to be finely pruned. Therefore, the kiwi mother trees in the orchard are generally trimmed very neatly and shaped.
Judgment points: The tree shape growth is very compact, the pruning is very rough, generally a public tree, on the contrary, the tree shape growth is very loose, the pruning is very regular is generally the mother tree.
Second, look at the branches
The male and female trees of kiwifruit are different in the appearance of the stem branches, and we can judge whether the kiwi tree is a male or female tree by observing the characteristics of the stem branches.
How to make a decision:
(1) The stems and branches of public trees generally have more fine hairs, and those who have hairy hairs on the stems and branches are basically public trees! On the contrary, the stem branches of the general kiwi mother tree are relatively smooth and there is no fine villi, even if the stem branches of the mother tree occasionally have a little hair, then the villi on the stem branches are very rare.
(2) The distance between buds and buds on the stems of male trees (bud spacing) is generally relatively small and narrow, while the distance between buds and buds (bud spacing) on the stems of the mother tree is generally relatively large and wide, in judging whether a kiwi is a male tree or a mother tree, we can basically know the size of the bud spacing on the branches.
(3) The internodes of the male stem branches are generally relatively thick and short, while the internodes of the stem branches of the mother tree are generally more slender.
Key points of discernment:
(1) The stem branches are not smooth and the fine hairs are many and dense, and the female trees are smooth and hairless or sparse on the stem branches.
(2) The male tree with small bud spacing on the stem branches and the large bud spacing on the stem branches is the mother tree.
(3) The thick and short branches of the stem are male trees, and the thin and long stem branches are mother trees.
Three look at the bud eyes
There is a difference between the male and female trees of kiwifruit in the characteristics of the bud eye, and we can judge whether the kiwi tree is a male or female tree through the difference in the bud eye during the winter fruit tree dormancy period (easy to accurately judge).
Judgment method: The bud eyes on the male tree are generally protruding outward (not absolute), and the distance between the bud eye and the bud eye on the male tree is relatively narrow; the difference is that the bud eye on the mother tree is generally concave inward (not absolute), and the distance between the bud eye and the bud eye on the mother tree is relatively wide.
Judgment points: The bud eye is protruding outward and exposed and the bud spacing is small, which is generally a male tree, and the bud eye is concave and hidden inward and the bud spacing is large, which is generally a mother tree.
Look at the buds of the flowers four times
The male and female trees of kiwifruit are different in buds and flowers, and we can judge whether the kiwi tree is a male or female tree by observing the characteristics of the bud flowers.
(1) Look at the number and distribution of buds. In general, the number of buds on the male tree is relatively large, the bud distribution is relatively dense, the bud size is relatively small, the buds on a single fruit stalk are often seven or eight to more than ten, these buds will grow compactly in one place; and the number of buds on the mother tree is relatively small, the bud distribution is relatively loose, the bud size is relatively large, the buds on a single stalk are only 1-3, and these buds grow to look rare and loose.
(2) Look at the morning and evening of the flowering time. Under normal circumstances, the male tree of kiwifruit will flower earlier and the flower size will be smaller, while the mother tree will flower slightly later and the flower will be larger.
(3) See if there is pollen on the flowers. In general, male tree flowers tend to have a ring of pollen on the side of the petals or pollen marks on the flowers when they bloom, while the flowers on the mother tree have flower hearts but no stigmas and no pollen marks on the petals.
(4) See if there are flower buds and stigmas on the flowers. The flowers of the male flower have only flower buds, but there is no pollinated stigma in the middle of the flower, whereas the flower of the mother flower has both flower buds (a few do not), and there are many stigmas in the middle of the flower that are used to receive pollen fertilization.
(5) Look at the length of the flowering period. In general, the flowering cycle time of male trees is relatively long (long flowering period, flowering period is more than ten days), while the flowering cycle time of the mother tree is relatively short (short flowering period, flowering period is only a few days).
(6) Look at the ovary and young fruits after flowering. There is no ovary formation after the male tree blossoms, and it will not bear small fruits after flowering, while the mother tree will have a distinctly prominent ovary formation after flowering, and small fruits will be produced after flowering.
(1) The flower buds are many and small and the buds are gathered together and grow compactly in one place, and the female tree is a female tree with few and large buds and sparse buds on the branches.
(2) The public tree with early flowering, small flowers and long flowering period is the mother tree, and the mother tree with late flowering, large flowers and short flowering period is the mother tree.
(3) The flower side is a male tree with powder, and the flower has a heart and no stigma is a mother tree.
(4) The flowers with pollen or pollen residue marks are public trees, and the flowers have no pollen and stigma or no pollen residue traces on the mother tree.
(5) The middle of the flower is a male tree with a bud and no stigma, and the middle of the flower has both a bud and a stigma is a mother tree.
(6) After flowering, it is the male tree that cannot form a ovary and cannot bear young fruits, on the contrary, it is the mother tree that can form an ovary after flowering and can bear young fruits.
Five look at the leaves
There is a difference in leaf characteristics between the male and female trees of kiwifruit, and we can judge whether the kiwi tree is a male or female tree by the difference in leaves during the growth period of the fruit tree.
Judgment method: The leaf size of the male tree is relatively large, the leaf shape is relatively round, the leaf color is darker, the leaf is thicker, at the same time, the leaf surface of the male tree is relatively rough and not smooth, the leaf hair on the leaf is more, and the back of the leaf is mostly gray-green-white; on the contrary, the leaf of the mother tree is relatively small, the leaf shape is relatively slender (leaf tip), the leaf color is relatively light, the leaf blade is relatively thin, at the same time, the leaf leaf villiness is less, the leaf surface is smoother, and the back of the leaf is mostly grayish white.
Key points of judgment: the leaves are large, thick, round, dark in color, the surface of the leaves is rough, the back of the leaf is sparse and the back of the leaf is light gray and green, which is generally the male tree of the kiwi; the leaves are small, thin, pointed, light in color, and the leaf surface is smooth, the back of the leaf is dense and the back of the leaf is dark gray-white, which is generally the mother tree of the kiwi.
Six look at the bark
There is a difference between the male and female trees of kiwifruit in terms of bark characteristics, and we can judge whether the kiwi tree is a male or female tree by observing the difference in bark.
Judgment method: There are more small spots on the bark of the male tree and the degree of convexity is more obvious, the touch is rough, and the stomata of the bark are mostly round; the small spots on the bark of the mother tree are relatively few and the degree of convexity is relatively shallow, the touch is smoother, and the stomata on the bark are mostly long.
Judgment points: there are more bumps and spots on the bark, and the touch feel is rough, which is generally a public tree, and the bark has fewer bump spots and a smooth touch feel
The above is the agricultural technology small back basket to share the kiwi tree and the mother tree identification and judgment method, in the future, when you buy a kiwi tree, or when you can't recognize the mother of the kiwi tree, the comprehensive use of the above methods can accurately determine whether it is a male tree or a mother tree.
Precautions for planting kiwi fruit trees:
Finally, the agricultural technology basket also reminds everyone in particular: in the future, when you plant kiwi trees behind the front house, you must plant two trees (a male tree + a mother tree), if you only plant one tree, then even if your family tree is planted for many years, even if your kiwi tree grows well, you are likely to not see its fruit or eat kiwi fruit - because the kiwi tree is a single species, basically can not bear fruit. If your family grows a kiwi orchard, then you need to plant a certain amount of male trees in the orchard for pollination, under normal circumstances, the ratio of kiwi trees to mother trees in an orchard is more appropriate at 1:5-8.
