Why don t pruned willow leaf peach blossoms bloom?

The scientific name of willow leaf peach blossom is oleander.

Scientific name in Chinese. Latin scientific name.

nerium oleander l.

Nickname. Safflower oleander, willow-leaved peach tree, peach, called out of winter, willow-leaved tree, peach plum, wolf.

Oleander (scientific name: Nerium oleander L.).Oleander is an evergreen erect shrub, up to 5 meters high, with gray-green branches, ridged young branches, slightly hairy, and hairy when old.

The leaves are 3-4 whorls, the leaf surface is dark green, the leaf back is light green, the midrib is trapped in the leaf surface, the petiole is flattened, the inflorescence is apical, the corolla is dark red or pink, the corolla is single-petaled and 5-lobed, the corolla is funnel-shaped, the seeds are oblong, the flowering period is almost all year round, and the summer and autumn are the most prosperous; The fruiting period is generally in winter and spring, and cultivation rarely bears fruit.

The top branch of oleander has a special property of three points, and can be pruned and shaped according to needs. If you need a three-pronged nine-top shape, you can cut a small batch at the top of the three-pronged shape to separate the nine tops. If you need nine tops and eighteen branches, you can leave six branches and cut them off from the top leaf axils to give birth to eighteen branches.

Pruning time should be after each flowering. In the north, oleander blooms in October for the surrounding and elsewhere. The flowers should be picked in time to ensure the concentration of nutrients.

The same is pruned in four times: one is after the rain in the spring valley; the second is between July and August; The third is October, and the fourth is winter cutting. If you want to bloom indoors, move it indoors to about 15 hours of sunlight.

Prune immediately after flowering, otherwise, the flowers will be few and small, or even not bloom. Through pruning, the branches are evenly dispersed, the flowers are large and gorgeous, and the tree shape is beautiful.

Oleander is a flower that prefers fertilizer and water, and prefers neutral or slightly acidic soils. On fertilizer, organic soil miscellaneous fertilizer accounting for about 20% of the potting soil should be maintained. If used for chicken manure, 15% is sufficient.

Dig a ring ditch around the pot, apply fertilizer and cover with soil. After the fertilizer is applied during the Qingming Festival, the soybean cake water made by adding water is applied every ten days or so; After the fertilizer is applied in the 24 solar terms, soybean cake water or peanut cake water or ten times the chicken manure liquid is applied every ten days or so. Without the above-mentioned fertilizer, you can add five to seven times water to the urine of a person who has been rotting for more than seven days, pour it along the edge of the pot, and then water it thoroughly.

Fertilizers with more nitrogen are thin, light, less, and diligent, and strictly prevent burning roots.

It is now past the flowering season of peach blossoms. The general peach blossoms bloom in March.

This plant is generally new branches that bloom and old branches do not bloom.

The main purpose of pruning peach trees during the growing season is to improve ventilation and light transmission conditions, promote fruit coloring and improve fruit quality by thinning overly dense branches and long shoots, so can peach trees still be pruned after flowering? Let me take you to find out.

1. The peach tree can be pruned when it blooms.

2. After the peach tree blooms, nectarines are gradually formed, and the branches and over-dense branches without hanging fruits can be cut off, which can reduce nutrient consumption and allow young fruits to grow better.

3. In addition, at this time, it is necessary to properly thin the fruits, and sort out the places with too many hanging fruits, so that the nutrition of the young fruits can be more balanced.

OK.

Although peach tree cuttings can survive, it is not easy to survive. Now the common ones are basically grafted and propagated peach trees, generally. Cuttings don't survive, but they do occasionally do, but fewer of them do.

Therefore, if you want to plant peaches, it is best to choose to plant them, and if you choose cuttings, it also depends on the specific time and conditions of the cuttings.

Peach branch cuttings method: 1. Use hard branch cuttings in spring and soft branch cuttings in the rainy season. 2. Cuttings must grow strong and full.

3. The cutting time of hard branches is mainly in spring, and the cuttings are cut obliquely about 20cm. In order to prevent disease infection and promote rooting, the lower end of the cuttings should be preferably 50% fungicide and 600-1 200 times of mycochloride, and 750-4500 mg l of indole butyrate should be quickly dipped in cuttings, with a plant row spacing of 4cm 30cm, and the cutting depth should be 2 3 of the length of the cuttings.

Peach blossom branch cultivation method: first cut off the excess leaves at the root of the peach blossom branch, the root cut is neat, there should be no splitting and disease spots, and the roots of the branch can also be scorched with fire. Then the roots of the peach blossom branches were soaked in a 5000 times potassium permanganate solution for a few minutes.

Finally, pour water into the vase, add a small amount of multi-element nutrient solution to it, and insert it into the peach blossom branch. Hydroponics is recommended for peach blossom branches, where the branches are placed in a warm place with scattered light but the temperature is not too high. Do not get exposed to direct sunlight to avoid wilting or flowering too quickly.

The water in the vase does not need to be changed every day, generally once every 4-5 days.

<> peach trees can be pruned when they bloom, and when the peach blossoms bloom in spring, you can prune off some long branches and fruitless branches at this time to promote the nutrient accumulation of young fruits. Prune the dense branches, and remove the young fruits with small weak fruit shape, so as to leave the fruit at a distance, which is conducive to plant ventilation and ventilation, and improves the photosynthesis of leaves.

1. The peach tree blooms in the spring season every year, when the young peaches begin to form and hang on the branches. We can do some pruning, first of all, some fruitless branches, rotten branches, and some overgrown branches with a prune.

2. When pruning, the main and secondary should be clear, the structure should be reasonable, the pruning to reach the inner branch should not be too dense, and the upper surrounding branch should not be too strong. The flower branches that grow too thick should also be pruned off, which can improve the photosynthesis of leaf cryptofibrous sheets and facilitate the nutrient accumulation of young peaches.

1. Pay attention to the principle of winter pruning when pruning, that is, to go to the small and leave the big, to the weak and to the strong, to the branches with less fruit, and to leave the branches with more fruits. In addition, it should be noted that after flowering in spring, it is enough to leave the fruit according to the distance, but it is necessary to leave the branches reasonably.

2. Pay attention to disinfection after pruning, so as to avoid bacterial infection affecting the healthy growth of plants. Get plenty of sunlight after pruning to soak up the entire peach tree. A layer of insecticide can be sprayed during pruning, which can effectively prevent the occurrence of pests and diseases.

Can be cut, the peach tree is in the spring of each year, at this time the young peach begins to form, open and hang full of branches, peach tree flowering and pruning, in order to artificially create a high-yield tree shape and reasonable structure, promote the rapid formation of the tree, make the tree ventilation and light during the full fruit period, save the nutrition of the tree, continuous yield, high quality, delay the aging of the tree.

After the peach blossoms, the leaves of the peach tree germinate, because the peach tree buds have early maturity, high germination rate and branching ability, and large growth. When the new shoots are formed, the buds can germinate in the same year, forming a secondary tip, and some even form a third tip, and the branch level is secondary. The peach tree has poor trunk performance, and can better control the lateral branches and support the middle stem through pruning.

Then due to the early maturity of peach tree buds and the characteristics of large growth, if not pruned, the peach tree will grow wildly, easy to flower, early fruit, fast aging, so pruning will make the branches reasonably renewed, otherwise the tree body will grow up to cause internal baldness, external fruit, seriously affect the yield and quality of fruits, at the same time, the tree body is closed, and serious pests and diseases occur.
