Why did the Camellia oleifera tree die by itself? What is the disease of Camellia oleifera die?

Why did Camellia oleifera die on its own? This may be that the fir tree has a life cycle, and when it grows to a certain age, it will die on its own, and this time it will make his business.

It should be said that like a person, he is also sick, so he will cry, and it is usually difficult to cry to death if he is familiar with normal words, unless he dies and does a kind from the inside to the outside.

Causes of the decay of Camellia oleifera trees.

Camellia oil is the best vegetable oil that people like to eat, but most of the Camellia oleifera trees are easy to age after fruiting, and the yield is decreasing year by year. Why does Camellia oleifera decay? The reasons for this are believed to be as follows:

1. There is no loose soil fertilization. Most farmers do not enter the mountains until the tea is ripe, so there is no talk of fertilizing the loose soil of Camellia oleifera at all. Year after year, the nutrients in the soil are gradually depleted, eventually causing the tea plants to become malnourished and less fruitful.

2. There is no pruning update. Pruning can promote the growth of new branches and maintain the longevity of Camellia oleifera trees, but farmers rarely prune Camellia oleifera trees.

3. There is no tree protection and insect protection. The long-term unmanaged camellia tree will cause parasitic vines such as thorns to entangle, resulting in shade, thereby affecting the growth of the tree. After the occurrence of insect borers, ants and other pests and diseases in Camellia oleifera, few people control them, resulting in the gradual aging of Camellia oleifera trees.

What is Camellia oleifera?

Camellia oleifera, also known as tea tree, tea oil tree, white flower tea. Camellia oleifera belongs to the tea family, a small evergreen tree. Because its seeds can be pressed for oil (tea oil) for consumption, it is named.

Camellia oil is a high-quality edible oil. It can also be used as lubricating oil and anti-rust oil in industry. Tea cakes are both pesticides and fertilizers, which can improve the water storage capacity of farmland and prevent and control pests in rice fields.

The peel is the raw material for the extraction of tannin gum.

The seeds contain more than 30% oil, which is used for edible, moisturizing, and medicine, and can be used to make candles and soap, and can also be used as a substitute for engine oil. Camellia oleifera, along with oil palm, olive and coconut, is known as the world's four major woody edible oil plants. Camellia oleifera has a high comprehensive utilization value, tea seed meal contains tea saponin, tea seed polysaccharides, tea seed protein, etc., they are all raw materials for chemical, light industry, food, feed industry products, etc., tea seed husk can also be made into furfural, activated carbon, etc., tea ash shampoo can kill lice including insect eggs.

Tea trees are fine, dense and heavy, heavy in the hand, very hard, is the best material for making spinning tops and slingshots, and because of its natural texture of tea trees, it is also a high-grade material for making high-grade wooden buttons.

Summary. Reasonable fertilization, determine the dosage: as far as possible to achieve the soil testing formula, N, P, K reasonable ratio. 3 In April, top dressing should be applied, and quick-acting, compound fertilizer or special organic fertilizer should be applied. 11 Apply overwintering fertilizer in February, mainly organic fertilizer, soil miscellaneous fertilizer and manure.

According to the growth and color of young trees, trace elements such as boron, magnesium, manganese, zinc, etc. should be appropriately supplemented. At the same time, according to the growth characteristics of young Camellia oleifera forests, fertilization was applied according to the needs of growth and development. Apply organic fertilizer in winter, it is the main nutrition of young forests during the whole growth period, a plant can be as high as 10-20 kg, increase nitrogen fertilizer in early spring before the shoots germinate, in order to extract the leaves and flower buds differentiation, fruit growth needs, 100-400 grams per plant; n, p, k with 2:

A 1:1 ratio is better.

The general principle of fertilization of Camellia oleifera seedlings: the tree is mainly vegetative growth, and the fertilization is mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer, and the main focus is on spring and summer shoots.

In the year of planting, due to the application of sufficient basal fertilizer, fertilizer can be omitted. 3 In April, top dressing is applied, and the fast-acting compound fertilizer or special organic fertilizer is mainly applied, with kilograms per plant. 11 In February, overwintering fertilizer was applied, mainly organic fertilizer, soil miscellaneous fertilizer and manure, 5 10 kg per plant.

The amount of fertilizer increased year by year with the growth of the tree.

Camellia oleifera trees have been hanging fruit for seven years, why are they slowly dying.

Hello, it may be a lack of trace elements such as iron, zinc, manganese, and boron.

Camellia oleifera is easily attacked by borers, ants and other pests and diseases.

The leaves slowly turn yellow. The roots were dialed out without looking at the insects.

The leaves are not injected with insects, which should be a problem with the roots.

Pruning can promote the growth of new branches and maintain the longevity of Camellia oleifera trees. However, it is more likely that the cause is soil problems, which lack trace elements.

How to supplement, reasonable fertilization, determine the dosage: as far as possible to achieve the soil testing formula, N, P, K reasonable ratio. 3 In April, top dressing should be applied, and quick-acting, compound fertilizer or special organic fertilizer should be applied.

11 Apply overwintering fertilizer in February, mainly organic fertilizer, soil miscellaneous fertilizer and manure. According to the growth and color of young trees, trace elements such as boron, magnesium, manganese, zinc, etc. should be appropriately supplemented. At the same time, according to the growth characteristics of young Camellia oleifera forests, fertilization was applied according to the needs of growth and development.

Apply organic fertilizer in winter, it is the main nutrition of the young forest god cover during the whole growth period, a plant can be as high as 10-20 kg, orange in early spring before the sprout of nitrogen fertilizer, in order to extract the tip of the leaf and flower bud differentiation, fruit growth needs, 100-400 grams per plant; N, P, and K are better in a ratio of 2:1:1.

The general principle of fertilization of Camellia oleifera seedlings: the tree is mainly vegetative growth, and the fertilization is mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizer, and the main attack is to draw shoots in spring and summer. In the year of planting, due to the application of sufficient basal fertilizer, fertilizer can be omitted.

3 In April, top dressing is applied, and the fast-acting compound fertilizer or special organic fertilizer is mainly applied, with kilograms per plant. 11 In February, overwintering fertilizer was applied, mainly organic fertilizer, soil miscellaneous fertilizer and manure, 5 10 kg per plant. The amount of fertilizer increased year by year with the growth of the tree.

Summary. Under normal circumstances, it is best not to soak the seedlings in the water for more than 12 hours, because the root system of the seedlings needs to breathe, and if the soaking time in the water is too long, the root system is easy to die due to lack of oxygen. If the roots are dead, the seedlings will lose the organs that absorb water and will not be able to grow properly, but there are some seedlings that need to be soaked in water before planting, such as raspberry seedlings, so that the roots can absorb enough water.

In general, it is best not to soak the sapling in the water for more than 12 hours, because the root system of the sapling needs to breathe, and if the soaking time in the water is too long, the root system is easy to die due to lack of oxygen. If the roots are dead, the seedlings will lose the organs that absorb water and will not be able to grow normally, but there are also some seedlings that need to be soaked in water before planting, such as raspberry seedlings, so that the roots can absorb enough water.

Will the Camellia oleifera tree survive after being flooded for two days and two nights?

It is possible to survive if it is not hit by a stone.

As long as the roots are not damaged. Good.

Summary. If the water continues for a day to two days and does not recede, the camellia tree will also be drowned, because the camellia tree also needs roots and breathing. And if the water does not recede, it will rot roots. Therefore, the Camellia oleifera tree will also die.

If the water continues for a day to two days and does not recede, the camellia tree will also be drowned, because the camellia tree also needs roots, and the virtual pants also need to breathe. Moreover, if the water holds the pure rock and does not retreat, it will also be poor and rotten roots. Therefore, the Camellia oleifera tree will also die.

Summary. Hello, I'm glad to answer for you, there are two main reasons why Camellia oleifera does not bear fruit: one is that the pregnancy rate is not high, Camellia oleifera is an insect-borne flower, and cross-flowering can be pollinated, flowering begins in mid-October, November is the full flowering period, flowering is basically over in late December, and a few are postponed to February of the following year.

Blooms are generally from 9 a.m. to 2 p.m. throughout the day; It is at its peak between 11 a.m. and 1 p.m., when temperatures are warmer, which is conducive to flower opening, pollination and insemination. It takes 6-8 days for a flower to go from bud to bud. Camellia oleifera is an insect-vector, cross-pollinating tree species, and the insects that help pollination mainly include ground bees, large tongue bees, Chinese honey bees, small flower bees, yellow-striped slender-waisted bees, fruit flies, meat flies, hemp flies and butterflies.

From the habits of flowers, it can be seen that in order to improve the fruiting rate, the premise is to increase the pollination rate, and special attention should be paid to the protection of pollinating insects.

The land that has been planted with camellia trees, why doesn't it bear fruit when replanted with camellia.

Hello, I am inquiring for you, please wait a while, I will reply to you immediately Hello, I am happy to answer for you, there are two main reasons why Camellia oleifera does not bear fruit: one is that the pregnancy rate is not high, Camellia oleifera is an insect-borne flower, and cross-flowers can be pollinated, In mid-October, the limb began to bloom, November was the peak flowering period, and the flowering was basically over in late December, and a few were extended to February of the following year. Blooms are generally from 9 a.m. to 2 p.m. throughout the day; It is at its peak between 11 a.m. and 1 p.m., when temperatures are warmer, which is conducive to flower opening, pollination and insemination.

It takes 6-8 days for a flower to go from bud to bud. Camellia oleifera is an insect-vector, cross-pollinating tree species, and the insects that help pollination mainly include ground bees, large tongue bees, Chinese honey bees, small flower bees, yellow-striped slender-waisted bees, fruit flies, meat flies, hemp flies and butterflies. It can be seen from the habits of flowers that in order to improve the fruiting rate, the premise is to increase the pollination rate, and special attention should be paid to the protection of pollination insects.

The main reason is that the pollen conception rate of the old Camellia oleifera is not high, because the old Camellia oleifera is an insect-borne flower, and cross-flowers can be pollinated, to improve the fruiting rate, it is necessary to improve the pollination rate, especially to protect the pollinating insects, and the insects that help pollination mainly include ground bees, large tongue bees, Chinese honey bees, small flower bees, yellow-striped slender-waisted bees, fruit flies, meat flies, hemp flies and chrysalis, etc., less spraying drugs. To improve the fruiting rate, it is necessary to improve the pollination rate, especially to protect the pollinating insects, and the insects that help pollination mainly include ground bees, large tongue bees, Chinese honey bees, small flower bees, yellow-striped slender-waisted bees, fruit flies, meat flies, hemp flies and butterflies, etc., less spraying drugs. 1. Temperature:

In the event of a late frost, the flowers will wither easily and the fruits may not be saved. If you want the old Camellia oleifera trees to grow at the right temperature, you must choose the right time to plant. 2. Moisture:

If the old Camellia oleifera trees encounter continuous rainy days when they bloom, it will affect the pollination of the old Camellia oleifera trees, and it is necessary to do a good job of drainage in time. 3. Light: If the light is not enough, it will lead to less fruit of the old Camellia oleifera tree, and the oil content in the fruit will also become lower, so the old Camellia oleifera tree should be placed in a place with sufficient light to maintain it.
