Generally, you can live for 20-25 years in the north. Generally, it can live in rainy areas and barren hills with high groundwater level 15 ~ 20 years. In sunny areas, well-managed orchards can still maintain their output when they are 25-30 years old.

To do a good job in peach tree care, we should start from the following two aspects: fertilization and pruning.

First, fertilization

Young trees should pay attention to controlling the application of nitrogen fertilizer, otherwise it will easily lead to excessive growth. After the full fruit stage, nitrogen fertilizer was added to enhance the tree vigor. The content of potassium in peach fruit is 3. Twice as much as nitrogen. If potassium fertilizer is applied, the fruit will be large and the yield will be high. In June, the basal fertilizer was 5438+00- 1 1, mainly organic fertilizer, accounting for 50% of the annual fertilization. Strong fruit fertilizer was applied in the hard core stage from late April to May. In addition, the peach garden should be cultivated regularly to weed, keep the soil loose, and drain water in time to prevent stagnant water from rotting roots.

Second, pruning

Pruning period includes winter pruning and summer pruning. Although the first-bearing trees (3-4 years after planting) have borne fruit, they grow vigorously with many white branches and dense branches. Pruning measures in summer, such as sprouting, coring and wringing, are used to suppress the strong and help the weak and maintain the balance of trees. Peach trees in full fruit stage, due to successive years of fruit, the tree vigor slowed down, the number of long branches and secondary branches decreased obviously, and the proportion of medium and short fruit branches increased. Give priority to short branches, delete the top branches and strong branches, improve the lighting conditions between branches, and update the weak branches in time. ?

1, nutrition

Peach is known as "Shoutao" and "Xiantao". Because of its delicious meat, it is also called "the first fruit in the world". Peach meat contains protein, fat, carbohydrate, crude fiber, calcium, phosphorus, iron, carotene, vitamin B 1, as well as organic acids, sugar and volatile oil.

Step 2: Eat

The gum secreted by peach tree trunk, commonly known as peach gum, can be used as adhesive. It is a polysaccharide, which can be produced by hydrolysis. Arabinose, galactose, xylose, rhamnose, glucuronic acid, etc. It can be eaten and used as medicine, and has the effects of breaking blood, promoting blood circulation and benefiting qi.
