In order to ensure the survival, robust growth and green elegance of potted bamboo, it is necessary to strengthen conservation management, and the main work includes the following aspects:

1. Water-controlling bamboos love moisture and are afraid of stagnant water. After pouring the basin, it should be watered for the first time, then keep the soil moist, and don't pour too much, otherwise it will easily rot the whip and root. From pot filling to survival stage, water is often sprayed on the leaves. If the basin is short of water, the bamboo leaves will curl. At this time, water them in time, and the bamboo leaves will unfold again. 65438+ water once every 0 to 2 days in summer, and water less in winter, but ensure that the basin soil is moist and prevent "dry freezing".

2. Fertilizer management Potted bamboo fertilizer is mainly organic fertilizer mixed with pot soil when potted. After bamboo survives, it should be properly topdressing, "thin fertilizer should be applied frequently", and 0.5% urea or 1.0% compound fertilizer should be applied to spring and summer water.

3. The main pests and diseases are aphids and scale insects, and 80% dichlorvos emulsion or 40% dimethoate emulsion can be sprayed 1000 times; The main diseases are sooty blotch, witches' broom and so on. Management should be strengthened and diseased plants should be pruned in time.

4. In other hot seasons, potted bamboos should be moved to the shade to avoid exposure in the hot sun. Greenhouse should be covered with sunshade net and sprayed with water to keep the leaves green. In winter, potted bamboo should be moved to the leeward or indoors, and the greenhouse should be covered with plastic film to keep warm.

Cultivation of potted bamboo

Bamboo is vigorous and graceful, elegant and pleasant. There are as many as 65,438+0,300 varieties, among which there are many gardening varieties for potted plants, such as Pteris, Phyllostachys pubescens, Phyllostachys pubescens and bamboo shoots.

First, the method of moving mother bamboo should be adopted when planting, and the survival rate is high. The mother bamboo with normal growth, dense bamboo nodes, low branching points and vigorous growth of bamboo whip (underground stem) can be selected for plant division. When digging, you should pay attention to leaving a bamboo whip about 30-60 cm long, and the whip (that is, the new stem) accounts for 2/3. Because new bamboo shoots grow from the whip, we should also pay attention to the joint between the bamboo pole and the whip and the fibrous roots on the whip, and they should be covered with soil, otherwise they will not survive easily.

Potted bamboos should be excavated once among 3-5 plants. Because the mother bamboo dehydrates quickly after it is unearthed, it must be planted immediately. You can stretch it flat, fill it with some water, and then cover it with soil and compact it to cover the original buried part of the mother bamboo. When filling or pressing the hole dry, don't hurt the whip root and bamboo shoots. Plant in a cool place and often spray with a small amount of water to avoid yellowing of the tip. After 1 month, the sun appears gradually, and the suitable transplanting time is around the autumnal equinox.

Second, shallow pot bare root planting. Bamboo is a shallow-rooted plant, so it should be planted in a shallow pot with wide mouth and bare roots. All branches and leaves that hinder the layout can be cut off, and a small rockery and strange stone can be added. A small amount of moss can be planted on the soil surface as a foil. The shallow basin where the bamboo whip grows is much larger than the deep basin with the same amount of soil, so it grows much better.

Third, soil and water management. Potted bamboo likes humidity, and the soil used must be acidic sandy loam with good drainage, preferably mixed with 1/2 mountain humus, and avoid saline-alkali clay. Potted bamboo prefers shallow planting of bare roots, and avoids deep burial in thick soil. Potted soil should be dry and muddy. Don't let the sun shine directly in summer, water it once every morning and spray the branches and leaves at night to keep the potted bamboo green. When the temperature drops to about 10℃, it should be moved indoors to avoid litter, and it is advisable to keep it above 10℃ in winter.

Fourth, bamboo likes fertilization, but potted bamboo is not suitable for fertilization. Because potted bamboo is important for viewing, it should be short and controlled between 50-60cm, so it is not easy to pick the heart or cut it. Due to the limitation of shallow basin soil, if the amount of fertilization can be controlled, Hsinchu will definitely be short. If fertilization is applied blindly, potted bamboo will grow tall and thick, or even grow wildly, completely losing its small and unique charm. Especially, applying less nitrogen fertilizer is beneficial to dwarf potted bamboo.

Pots of bamboo will be planted in rainy season, and bamboo shoots will be born next year. If the jointing of new bamboo shoots is too long and unsightly, you can gently peel off the shell, the bamboo shoots will stop jointing, and the side branches near the base need to be cut off. In order to promote the regeneration of potted bamboo and make it short and green, it should be pruned every winter. The principle is: cut the old and keep the tender, cut the dense and keep the sparse, and cut the weak and keep the strong. When changing pots every year, the dead bamboo should be properly removed to keep the plant beautiful. Because the potted plants were affected, the growth was inhibited, resulting in dwarfing of potted bamboo.
