The latest key points of flowering management of apple trees

Apple is a very common fruit in our country, and there are many people who grow apples. When growing apples, if you want to improve the fruit setting rate and fruit quality, it is necessary to do a good job of management. Apple has different management methods in each growing period, so how to manage it during the apple flowering period? The following editor brings you the key points of apple tree flowering management, let's have a look!

1. Artificial pollination

Artificial pollination is the main management measure to avoid abnormal weather and lack of pollination trees, which leads to low fruit setting rate of apples. First of all, we should select pollination trees, pollination trees to ensure that the same florescence, a lot of pollen. Then do a good job of collecting pollen before flowering, picking more flowers and less flowers. After picking the flowers, collect the pollen, rub the styles of the two flowers, put clean paper at the bottom, catch the anther, and then do a good job of preservation. Pollinate in full bloom and dip it with rubber or fur.

2. Thinning flowers and fruits

The work of flower and fruit thinning in the flowering stage of apple trees can effectively prevent the phenomenon of big and small years of apple trees, and can obviously improve the fruit quality. Flower thinning should be done in full bloom, and then fruit thinning should be carried out about a week after Xiehua. The whole work of thinning flowers and fruits should be completed within a month, and we should control the amount of thinning according to the load capacity of apple trees. If the load capacity is weak, it will be more sparse, otherwise it will be more sparse. We can carry on the flower and fruit thinning work according to the branches and fruits to ensure that the proportion of small fruit branches without fruit is about 30%, and the medium-sized ones is about 40%. Then thinning flowers according to each other, keeping a fruit every 20 centimeters or so.

3. Strengthen nutrition

After the apple enters the flowering stage, because the flowering needs to consume a lot of nutrition, so we must do a good job of topdressing in the flowering stage to provide sufficient nutrition for apple tree flowering. Urea should be sprayed about 3 times before and after flowering, then borax should be sprayed once during flowering, and potassium dihydrogen phosphate should be sprayed once after flowering. The demand for nutrition for the growth of apple trees is relatively comprehensive, so it is best to carry out a soil testing formula when topdressing, so as to facilitate the corresponding supplement of nutrition, improve the flowering quantity of apple trees and improve the planting efficiency.

4. Pest control

Flowering is a period of time when apple trees are relatively weak, during which they are very vulnerable to diseases and insect pests. For example, beetles, ring disease and so on, so we must do a good job in the prevention and control of diseases and insect pests. Strengthen prevention, control fertilizer and water quantity, promote the flowering and fruiting of apple trees, and enhance the disease resistance of apple trees. When abnormal conditions are found in apple trees, it is necessary to find out what the specific diseases and insect pests are, and carry out symptomatic prevention and control.

The above is a brief introduction to the main points of apple tree flowering management. The flowering management of apple trees must be paid more attention to to improve the flowering and fruit setting rate. That's all for today's introduction. This article is for reference only.
