How many years have the latest bayberry trees been planted?

Bayberry is produced in most parts of China and grows in hillsides or valleys at an altitude of 125-1500 meters. It is a famous fruit in the south of the Yangtze River in China. Do you know that bayberry can not bear fruit until it has been planted for several years? Below, the editor of Guizhou Agricultural Network will introduce to you how many years it will take to plant a bayberry tree to bear fruit.

How many years does the bayberry tree bear fruit?

If the grafted seedlings of red bayberry are cultivated properly, they can hang fruit in 4 to 5 years, and enter the full fruit stage after 8 years. The flowering period of red bayberry is April and the fruit is mature from June to July.

The reason why bayberry trees do not bear fruit

1. Lack of light: the crown of the big tree around the bayberry tree is too large to block the sun, and the bayberry tree does not get enough light.

2. The soil is too fertile: bayberry trees only grow longitudinally, not horizontally, and are not conducive to fruiting.

3. The climate is changeable: snow, rainstorm and cold air come one after another, and spring is the key season for the growth of red bayberry, so the climate change affects the growth and fruit of bayberry to a certain extent.

4. As a result, the age has not yet reached.

5. There is no pollination male tree.

The method of dealing with the sterility of Waxberry

1. Paclobutrazol spray crown: from the end of July to the end of September, the tree crown was sprayed with 200 × 10 to the negative 6th power of 500 × 10. The concentration depends on the variety and tree potential, such as the concentration of thick leaves and strong tree potential is relatively higher. In the same year, the spray can be put into production the next year, and the efficacy is 2 ~ 4 years. After the efficacy disappears, it can be used continuously. 0.5 grams of paclobutrazol can also be applied per square meter of projected canopy area.

2. Pruning and pressing: pruning in spring should be based on the principle of "controlling up and down, controlling outside and promoting inside, thinning big branches, leaving more small skills", or "opening skylight" to promote canopy ventilation and light, and promote flowering and fruiting. When the autumn shoot stops growing, you can use the rope to pull the branch, hang the medicine water bottle, or use the branch to support the branch to make the crown open, increase the angle of the big branch and ease the tree potential. During the flower bud differentiation period from the first ten days of August to the middle and last ten days of October, the branches were cut 1 / 2 times with a knife ring from 1 to 1.5 meters from the crown to promote flowering and fruiting. Ring cutting should account for 1, 2, 2, 3 of the whole tree. From February to March in spring or from early September to mid-October in autumn, the orchard should be deeply rooted.

3. Pollination of male bayberry trees: production requires not less than 2 male (male) bayberry trees per 60,90 bayberry trees.

4. Fertilization and soil cultivation: pig and cattle pen rotten manure, compost and garbage sieving fertilizer were applied three times a year, the first in late February, the second in mid-late May, and the third in early August. Each big tree applies 1530 kg of garbage fertilizer and 40kg of miscellaneous fertilizer. Cultivate the soil once a year. Each plant weighs 200kg and 250kg.

5. Control of diseases and pests: red bayberry has strong disease resistance, but when there are scale insects and debt-avoiding insects on the tree, it should also be sprayed in the larval stage, and the leaves are easily infected by spot disease. 0.5% Bordeaux solution should be sprayed to control. Although the occurrence of leprosy on branches is relatively rare, it should also be prevented and disinfected. After removing the disease spot, brush the wound with 1-6-10 concentrated alkaline water to sterilize the wound.
