In addition to its strong formaldehyde adsorption capacity, Phyllostachys praecox can effectively absorb a large amount of carbon dioxide at night, and also preferentially adsorb harmful substances such as benzene, which has obvious effects on purifying and eliminating indoor polluted gases. Tortoise shell bamboo likes to be moist and should not be watered frequently. Keep the basin soil moist, avoid direct sunlight and not be cold-resistant.
When we buy indoor plants, we can't measure it by the single effect of absorbing formaldehyde, but it is equally effective for the balance of water and the release of oxygen by photosynthesis. Also consider the beauty, and choose the appropriate green plants in combination with the interior decoration style.
Although plants can absorb formaldehyde in indoor air to some extent, their effects are still limited. In fact, the most effective way to release formaldehyde is to open the window for ventilation. It is often opened indoors for ventilation, but it is more effective than any other plants, and the effect is good, and it also saves money.
Cultivation method of Phyllostachys pubescens:
1, soil
Phyllostachys pubescens prefers to grow in slightly acidic soil, but does not like to grow in alkaline soil. When preparing soil for Phyllostachys pubescens, the soil should be loose, breathable and well drained. It can be mixed with humus soil, garden soil and river sand to make bamboo grow vigorously.
2. Lighting.
Big bamboo is shade-tolerant, and doesn't like strong sunlight, which easily leads to yellow leaves or sunburn. Therefore, when cultivating Bambusa macrophylla, it needs to be maintained in a place where light is scattered, and it cannot be exposed to strong sunlight.
3. water.
Dazhu likes humidity, so water it well. If the soil is dry, the leaves will turn yellow, which will affect health. When maintaining Bambusa macrophylla daily, we should keep the soil moist and water it in time in summer.
4. Fertilize.
It takes about 15~20 days to apply fully decomposed organic fertilizer solution or cake fertilizer water during the growth period of Phyllostachys praecox, and the amount of fertilization should be controlled well. It is not necessary to apply too much fertilizer at a time, but to apply thin fertilizer frequently.
Step 5 trim.
In order to effectively ensure the beauty of Phyllostachys praecox after growth, appropriate pruning can be carried out, for example, where the leaves of the whole stem node grow too densely and the branches grow too long, if the stems and vines want to grow rapidly, the old leaves at the lower part can be appropriately pruned.
6, pest control.
Phyllostachys praecox is prone to diseases and insect pests during its growth, and the common diseases are mainly gray leaf spot. The control measures can be sprayed with 70% thiophanate 1000 times solution or 0.5% bordeaux solution, the common pests are mainly scale insects, and the control measures can be sprayed with 40% omethoate emulsion 1000 times solution.
7. Change pots.
Bamboo grows very fast, so in order to make it have enough space, it is necessary to change the pot once a year, preferably in March-April, and some old soil and dead roots can be removed by the way before changing the next size.
