The latest course on Management techniques and methods before Apple flowering

Apple is the most popular fruit in China, which is basically grown in all parts of our country. When planting apple trees, management is very important, and we should adjust the management methods reasonably according to the growth stage of apple trees. Especially before the apple tree blossoms, how to manage the apple tree before it blossoms? The following editor brings you the pre-flowering management technology of Apple. Let's have a look!

1. Pre-flowering re-cutting

Pre-flowering re-pruning is a very important management work of apple trees before flowering. It is also the main measure to restore the damage to the tree due to improper winter cutting or climate, mechanical damage and other reasons. The proportion of flower buds and leaf buds on fruit trees can be adjusted. If it is a young fruit tree and a young fruit tree, it is necessary to retain as many flower buds as possible to promote fruit and increase yield. For the flourishing fruit trees in the big year, the ratio of flower buds to leaf buds should be kept at 1:3 and 1:2. The amount of flower buds should not be too much, and for trees with unbalanced power in various backbone trees and branches, it is necessary to reasonably adjust the amount of flowers.

2. Fertilizer and water management

Fertilizer and water management is also very important before flowering, we should not only apply sufficient organic fertilizer, but also apply chemical fertilizer reasonably. Meet the nutrients needed for apple trees to blossom and bear fruit. The amount of topdressing should be controlled according to soil fertility, tree potential, tree age and yield. For example, if the soil is fertile and the trees are strong, then do not apply fertilizer, on the contrary, you should apply more chemical fertilizer. For apple trees that bear fruit for the first time, each tree should be fertilized with ammonium sulfate about 1kg or 30kg in human feces and urine.

For fruit trees, the application amount of ammonium sulfate is kept at about 2kg, if it is human feces, then it is about 60-90kg. And it is best to apply an appropriate amount of phosphorus and potassium fertilizer. It can not only improve the fruit setting rate of apple, but also is very beneficial to the quality of apple fruit. Watering should usually be carried out in combination with topdressing work from March to April. Because the temperature at this time is not very high, so watering should not be too much to prevent the decrease of ground temperature and affect the root development of apple trees. For orchards that were not irrigated with frozen water years ago, they should be watered in time to promote the germination of fruit trees and increase the amount of flowers and fruits.

3. Pest control

The pre-flowering time of apple trees is usually in early spring. Early spring is the key period for the prevention and control of diseases and insect pests in apple trees. first of all, we have to scrape off the rotten and diseased bark. Special attention should be paid to wheel disease spots, old warped bark and other bark. Then do a good job in clearing the garden, avoid the spread of the disease, reduce the base of insect pests in the garden, and pay attention to smear an appropriate amount of protective agent on the wound. Before the fruit trees sprout and after pruning, the whole orchard should be sprayed with appropriate amount of Baume stone sulfur mixture and other chemicals. If the decay is serious, spray Fumei arsenic wettable powder once.

The above is a brief introduction to Apple's pre-flowering management technology. That's all for today's introduction. This article is for reference only. I hope it can help you all.
