Do you know why the black olive fruit tree does not bear fruit?

Low fertilizer and water input. In the young tree stage, if the fertilizer and watering are less and the growth is allowed to grow, the young tree is not nutritious enough and it is difficult to meet the material needs of the flowering stage. To this"Hungry type"Young trees should be increased with fertilizer and water to improve their nutritional status in order to bear fruit in time.

Improper pruning. For young tree pruning, if it is shortened once a year, and it is too heavy and short, it will inevitably cause vigorous growth, unstable tree momentum, and it is difficult to flower and bear fruit. The pruning of young trees should be based on the long-term goal of shaping, with the purpose of increasing branches and expanding the crown and stabilizing the tree potential.

The angle of the branch does not open. If it is a young tree with no opening at the angle of the branch, the tree will inevitably be vigorous and not slow, the growth center will move outward, the inner chamber will be closed, the ventilation and light transmission conditions will deteriorate, and it will be difficult to flower and bear fruit. The improvement measure is to open the branch angle during the growing season by brace, pull, pin, hanging, etc., which is the structural basis for early fruiting.

Effects of pests and diseases and intercropping. The orchard management is extensive, and most of the pests and diseases are serious. Branches, shoots and leaves were damaged to varying degrees, which inhibited normal growth and delayed the fruiting period.

Some orchards unscientifically plant some intercrops, compete with fruit trees for fertilizer and water, compete for light, and even become the host of fruit tree pests, which is extremely detrimental to the growth and fruiting of fruit trees. <>

The flowers that bloom are male. Because the black olive fruit tree is divided into male and hermaphroditic plants. The flowers produced by the male plant are all male flowers, and the flowers do not have an ovary, so they are not fruit-bearing plants.

Solution: Re-graft the bisexual spikes that can bear fruit on the plant, so as to produce both sexually fertilized flowers that can be self-pollinated and fertilized, so as to bloom and set fruit normally; Bad weather during flowering. For example, low temperature and rain affect pollination and fertilization.

Solution: Spray milliliters of brassinolide before and after flowering, and add borax solution and potassium dihydrogen phosphate solution to improve the stress resistance of plant flowers, improve the vitality of male pollen and the tolerance of female stigma and reduce flower and fruit drop. Anthrax disease is encountered during flowering. Before flowering, spray the canopy with fungicides such as 25% Mixian emulsifiable concentrate 1000 times.

Summary. Hello, olive trees only bloom and do not bear fruit for the following reasons.

1. No pollination. During the flowering season, there should be bees, flying insects, etc. If there is no or less pollination, it will not pollinate well and it will not bear fruit.

2. Lack of phosphate fertilizer. One month before flowering, increase the application of phosphorus fertilizer to promote flowering and fruiting. 3. After flowering, cut a few knives at the base of the tree to the bark.

Its function is to partially cut off the nutrients produced by the leaves, and the downward channel, so that it can supply the growth of flowers and fruits. The cutting position can be circumferentially cut half a circle, and the width is less than 10 mm, and the skin of this 10 mm can be peeled off. In this way, it will bear fruit, dear, does anyone know that there is an olive tree in my house that only blooms and does not bear fruit.

Hello, I've seen your question, I'm sorting out the answer, please wait a while Hello, I've seen your question, I'm now hand-hungry for you, but it takes a little time, please wait patiently, thank you

Hello, the olive wild tree only blooms and does not bear fruit There are several reasons for the remaining chain Oh pro 1, no pollination. During the flowering season, there should be bees, flying insects, etc. If there is no or less pollination, it will not pollinate well and it will not bear fruit.

2. Lack of phosphate fertilizer. One month before flowering, increase the application of phosphorus fertilizer to promote flowering and fruiting. 3. After flowering, cut a few knives at the base of the tree, and cut the vertical ridge to the bark.

Its function is to partially cut off the nutrients produced by the leaves, and the downward channel, so that it can supply the growth of flowers and fruits. The cutting position can be circumferentially cut half a circle, and the width is less than 10 mm, and the skin of this 10 mm can be peeled off. In this way, it will turn out dear, do you think there is anything else that needs help?

1. Cultivate the autumn shoots (fruiting branches) of the year. The fruiting mother branch is generally required to be extracted in mid to late August of the current year, and the winter shoots are no longer drawn after the autumn shoots are fully matured (about 20 days before the autumn shoots are extracted, each plant bears 10 kg of fruit, and generally applies three 15 compound fertilizers of about kg per plant;

2. From December to early January of the following year, apply 5-8 kg of organic fertilizer such as rotting chicken manure to each plant, and sprinkle about kg of lime on the tree tray;

3. When the tender shoots of the fruiting mother branches grow to 10-15 cm and the leaves have been completed, mix 200 grams of 15% paclobutrazol with 60 kg of water, and add Bika potassium dihydrogen phosphate and borax spraying the crown once to promote the enrichment of autumn shoots;

4. The flower buds of the black olive tree are generally differentiated from March to late May, and then flower, before and after flowering, in order to preserve flowers and fruits, reduce fruit drop and improve quality.

Ask the teacher, how can Ulan's words be cultivated to bear fruit? This is that everyone's one is different, and if you want to cultivate you, that is, look at the instruction manual of his cultivation, and the varieties are also different.

Hello! 1. Cultivate robust seedlings, which can be grafted in the autumn of the current year or the spring of the following year, and the grafting method is mostly the embedding method. After grafting, cultivate strong seedlings and plant them;

2. Strengthen fertilizer and water management, cultivate strong black olive trees, 3. Do a good job of spring and autumn pruning, and promote the inner and outer fruits of the canopy. Due to the vigorous growth of black olive, stubbing and topping of summer shoots can promote branching and more fruiting.

4. The black olive likes warmth, and the growth period needs appropriate high temperature to grow vigorously, and the results are good, with an average annual temperature of more than 20 and no severe frost damage in winter, so it is necessary to pay attention to temperature management;

5. Strengthen the prevention of pests and diseases: black olive has strong resistance to stress and few diseases, but it is necessary to strengthen prevention and supply.
