How to prune branches? Huang Guolan is a white orchid.
It is best not to prune white orchids, but to replace them with tender heads, which can also control long branches. If you have to cut it, you should also grasp the time and carry out the necessary post-cutting care. Because the center of the lignified old branches of Prynne is soft cotton wool, it is easy to absorb water and infect bacteria and rot, and the water at the incision keeps seeping downwards, so the infected branches die step by step. Therefore, the pruning operation must be careful. First, cut it diagonally, and trim it flat. Secondly, it should be tied tightly with plastic paper and isolated from the outside world. If the above two points are not handled properly, when the incision is dry, never cut off the dry part again. The best way is to barbecue and sterilize here with a lighter, and then wrap it up so that the wound can't get any water and prevent further invasion of germs. Therefore, pruning must be carried out in sunny days, so as to make the cut dry as soon as possible and reduce the possibility of bacterial infection.
White orchids have a long flowering period, and can bloom all year round under suitable environmental conditions. But it is afraid of drought, waterlogging, cold and alkali.
In the north, it is regarded as a delicate flower. Therefore, the cultivation methods and precautions of white orchids need attention.
Hold the following four projects:
First of all, we need fertile, loose and well-drained culture soil. 5 parts of pine needle humus soil, 2 parts of coarse bran ash and 2 parts of coarse sand.
1 serving cooked manure, and it is forbidden to use fine sand or cohesive soil with poor air permeability. The upper basin is made of well-ventilated pottery basin (plain burning)
Pots), avoid using glazed pots, porcelain pots, teapot, etc. It is best to use a deep cylindrical flowerpot with an empty flowerpot and a brick frame under it.
Vent to prevent poor drainage; The bottom of the basin is covered with about 5 cm of slag and gravel.
Second, the moisture should be appropriate. White orchids belong to fleshy roots. If the soil in the basin is too wet, the leaves will turn yellow and fall off, and even the roots will rot. If it's too dry, it will
Flowers with curly and withered leaves are flowers that are afraid of both waterlogging and drought. When flowering, the petals are excessively opened, indicating that the water is insufficient and the water is suitable.
Bud-shaped; When the soil surface is dry and the soil is hard and cracked, it should be watered immediately. Water temperature and soil temperature must be consistent when watering.
Don't throw cold water or hot water suddenly. Water must be poured thoroughly, often pouring half will cause shallow roots. Do white orchids water in spring and autumn?
Water every day in midsummer and at night. Water should be reduced in late autumn and watered once every 10 day in winter. rainy season
Festivals should be moved to shelter from the rain.
Third, fear of alkali. White orchids like acidic soil, and the requirement for soil pH value is 5.5-6.3. In the northern region, white orchids are difficult to raise.
It is because the water and soil there are mostly alkaline that the protoplasm of white orchid cells is dissolved, which leads to the slow development and growth of flowers.
Poor growth. Often watered with fermented rice washing water, the effect is better.
Fourth, I'm afraid of being fat. White orchids like phosphorus and potassium fertilizers, but high concentrations should be avoided, otherwise reverse osmosis will occur, resulting in "physiological dryness" of plants.
"Drought, light wilting, or burned to death. The fertilization principle of white orchid is: "apply less, apply frequently and apply late". Practice has proved that dilute human excrement and bean cake water are mixed with mashed fish offal, rotten shrimp and chicken offal. After cooking, apply it every 3-5 days according to the ratio of fertilizer to water of 1:9, and add calcium sulfate when applying, which has a good effect and can make orchids fragrant.
Hope to adopt, thank you.
How to prune branches and flowers 1, watering too much will damage root respiration. Or watering is not thorough, the waist is cut off from water, and it does not penetrate to the end.
2, lack of elements.
Phosphorus is very important for the growth of roots. Lack of phosphorus will make plants short, with dark green leaves and underdeveloped roots. Phosphorus can be supplemented by foliar spraying of potassium dihydrogen phosphate and calcium superphosphate.
Potassium can enhance photosynthesis and promote the formation of chlorophyll. Without potassium, the old leaves will have spots and turn yellow gradually.
Calcium deficiency will inhibit the growth of plants, make the leaves twisted and gradually die from the tip.
Magnesium deficiency will gradually change the color of old leaves, but the veins will remain dark green.
Iron deficiency will make the leaves of the new fern turn gray-green, gradually turn yellow, and the leaves and aging will turn black.
Manganese deficiency can lead to necrotic spots on veins.
Barium deficiency leads to terminal bud death.
Lack of copper makes the leaves turn green, gradually turn yellow, and finally fall off and die.
The picture of how eggplant prunes branches can be learned in the palm garden, which has detailed pruning pictures (downloaded from the palm garden searched by 360 assistant AppBao Apple appstore and so on). )
How to prune the branches and leaves of a happy tree? If you want a happy tree to have more side branches, you can choose the heart. Picking the heart is to cut off the top of it so that it won't grow taller. Trim according to your own preferences.
If you want to be happy, you should pay attention to applying more potassium-rich fertilizers.
When watering at ordinary times, you can spray water on the stems and leaves. Pruning and shaping should be done before germination in spring.
How to prune jasmine's branches? Lift the whole jasmine from the bottom of the basin with a stick, take it out, knock off the soil at the roots, and cut off some long and dense old roots, diseased branches and weak branches; Too long and too dense branches should be cut and shortened, leaving more branches near the roots and evenly distributed. If the root has several branches, it can be separated from the base and planted separately. Generally, pruning can be carried out after each batch of flowers opens, and some leaves can be removed to promote the growth of buds without damaging the beauty of axillary buds and flowers. Pruned branches can be used as cuttings. Pruning of jasmine is very important in summer, except that most of the delicate branches after wintering are cut off in spring, leaving only a thick base for new buds to germinate. After the flower decays, the branches should be kept for 3-5 knots in time, and the top should be cut off to promote the sprouting of new branches and keep the flowers flourishing. Otherwise, a small number of secondary branches germinate at the top of the old branches, with few flowers and fine flowers. At the same time, in summer, the slender and even branches that jasmine often germinate consume nutrients, so they should be cut short in time and leave 1-2 leaves. In this way, powerful flowers will sprout from the branches and leaves, and then combined with pruning, the delicate branches on the two pairs of leaves and the third pair of leaves at the end of the branches will be cut off, so that the plants will be suitable in height, symmetrical and beautiful. Then take off all the old leaves, don't hurt them when picking them, and be careful not to pick them too wet. Pruning and picking leaves can promote the growth of new buds and more pregnant buds. In order to make it flourish, when the spring shoots grow to 4-5 knots, it is necessary to pick the heart. In the future, not only will there be more branches, but the plant shape will also be full. For branches without buds, two pairs of thin leaves at the top should also be picked to facilitate growth and flowering. As the flower proverb goes, "Jasmine is not pruned, showing weak branches and few flowers. Pruning requires monkeys and flowers are stable. "
Some people tend to pay more attention to fertilizer and water, ignoring pruning, and even reluctant to cut off the dead branches and old leaves after wintering, resulting in thin branches, small leaves, ugly plant types and poor flowers. In fact, in addition to fertilization, watering and sunbathing, potted jasmine must be pruned in time. As long as it is trimmed properly, it can make branches strong, leaves big and flowers many.
1. Before the Spring Festival sprouts, the branches in the last year can be appropriately cut short, and the base 10- 15 cm will be reserved, so that the most robust new branches will appear. If the new branches grow vigorously, they should be pulled out when they grow to 10 cm, and the secondary branches should be promoted, so that more flowers will bloom, and the plastering type will be compact and the ornamental value will be high.
2. Summer pruning is also very important. After the flower decays, 3-5 knots should be left for the branches in time, and the top should be cut off to promote them to sprout new branches and keep the flowers flourishing. Otherwise, a small number of secondary branches germinate at the top of the old branches, with few flowers and fine flowers.
3. In summer, the slender branches with uniform length that jasmine often germinate consume nutrients, and they should also be cut short in time, leaving 1-2 nodes, so that strong flower branches can germinate from this node quickly. Combined with pruning, the delicate branches on the two pairs of leaves and the third pair of leaves at the end of the branches should be cut off, so that the plants are highly suitable, symmetrical and beautiful.
4. Then remove all the old leaves. Don't hurt the leaves when picking, and be careful not to pick them when they are too wet. Pruning and picking leaves can promote the growth of new buds and more pregnant buds.
In order to make it flourish, when the spring shoots grow to 4-5 knots, it is necessary to pick the heart. In the future, not only will it cost more, but the plant type will also be full. For branches without buds, two pairs of thin leaves at the top should also be picked to facilitate growth and flowering.
Note: Pruning should be carried out in sunny days, which can be combined with thinning leaves, removing diseased branches and adjusting plants, which is beneficial to growth and flowering.
The 3-6-year-old seedlings of Jasmine blossom most vigorously, and then they will age year by year, so they need to be pruned and updated in time.
How to prune the grape branches? First, the principle of pruning. Grape is a vine deciduous fruit tree, which needs to be cut once a year in winter when planting. If vines are not pruned for many years, the whole shed will be covered with vines, and the dead branches, over-dense branches, weak branches, slender branches, pests and diseases, and disabled old vines will not be effectively removed, which will disturb the tree shape, affect the ventilation and light transmission between trees, cause the breeding of pests and diseases, and make the flowers and fruits fall off seriously, and there will be no harvest. Grape pruning in winter is to improve the above shortcomings, make the vines healthy and strong forever, and effectively control the upward movement of the resulting parts or the aging and baldness of the main vines behind them. Through pruning technology, the contradiction between aboveground and underground, growth and fruiting can be adjusted, the whole plant growth can be balanced, the fruit yield can be increased, and the quality of grape fruit can be improved.
Second, pruning time. It is more suitable to arrive in beginning of spring after defoliation, that is, from mid-June 65438+February to early February of the following year.
Third, pruning technology. Taking the grape trellis which has been planted for more than four years and each plant accounts for 6- 10 square meter as an example, the pruning method is explained.
1, cut off useless branches. First, cut off the old, weak, residual branches, dead branches, pests and diseases branches, slender branches (more than 0.5 cm in diameter) and some overlapping branches from the base.
2. cut the length. In practical application, the cutting length should be determined according to the different varieties, growth, position and maturity of branches. Results In principle, the pruning of mother branches should be based on the strong, medium and weak annual growth, that is, the strong branches should be kept long, the weak branches should be kept short, the ends should be kept long and the bases should be kept short. As far as the whole tree is concerned, it is necessary to combine long and short pruning, that is, the number of buds left is: long branches with 8 buds, middle branches with 4-7 buds, and short branches with 1-3 buds.
3. The number of branches and buds left by the bearing mother branch. The fruiting mother branch refers to the branch that produces new shoots and bears fruit in the second year. Too many branches will sprout too many new buds, which will affect the ventilation and light transmission of the frame surface and breed pests and diseases. At the same time, too much fruit will weaken the tree and affect the quality and growth of the next year. When pruning, the number of mother branches and buds is different because of the variety, frame type and tree shape. Take the above trellis as an example, 40-70 fruiting branches are usually selected, and the amount of buds left is 180-300. When pruning, we should also pay attention to make the main vines and their fruiting mother branches evenly distributed on the frame surface.
Fourth, pruning precautions. The diameter of the branches and vines at the cutting mouth should be above 1 cm. When pruning useless branches, they should be completely removed from the base. Cut branches and leaves should be burned or buried in a centralized way. At the same time, combine pruning in winter and apply sufficient organic fertilizer to lay a good foundation for next year's results. Hehe, I hope it helps you ~
Prune grape branches by removing tillers in early spring. Remove tillers from the rhizosphere. More vigorous new shoots should be picked, moderately growing new shoots should be picked lightly, and weak new shoots should not be picked, so that the branches and vines can be enriched continuously.
How to prune flowers and trees and the suitable time for pruning can be different according to varieties and cultivation purposes, which can generally be divided into dormancy pruning and growth pruning. First, dormant pruning. Most of them are carried out in winter dormancy or early spring when sap just begins to flow and buds are about to germinate. Perennial woody flowers, such as rose, hibiscus, poinsettia, pomegranate, crape myrtle, chrysanthemum and so on. Flowers on the branches of the current year can be pruned again during dormancy, which can promote the germination of new buds and increase flowering. For varieties that bloom in spring, such as peach, plum blossom and Yingchun. Flower buds are mostly formed on the branches of the previous year, so they should not be pruned before germination in winter or early spring, but only after flowering to promote the germination of new shoots and form the flower branches of the next year. Second, pruning during the growth period. In the growing season of flowers and trees or after flowering, pruning, coring, leaf picking and cutting off dead branches, diseased branches and long branches are the main methods, which should be carried out in time according to the growth and cultivation requirements of flowers and trees. Some flowers and trees generally do not need to be pruned frequently, such as azaleas and camellias. In order to keep the tree symmetrical and beautiful, some branches should be cut off as appropriate, but not pruned vigorously. Lianas only need to cut off branches of diseases and insect pests, dense branches and over-aged branches, and keep ventilation and light transmission.
