Bamboo is loved by Chinese people. It symbolizes rising step by step. Many lovers like to cultivate bamboo. But in the process of maintenance, bamboo leaves often turn yellow. How many fans know why bamboo leaves turn yellow? The following small series for you to introduce the bamboo in the maintenance process of yellow leaves cause analysis and solutions, let's have a look!
Water yellow: do not accumulate water in flowerpot, water is easy to rot, root and leaves are yellow.
Solution: put the flowers out of the basin and put them back into the basin after they are ventilated, cool and self blown.
2. Drought yellow: Bamboo likes to be wet. If watering is ignored or only the surface soil is poured, the roots do not absorb enough water, and the stems and leaves turn yellow slowly.
Solution: pay attention to watering enough and thoroughly.
3. Yellow: bamboo can not be directly in the strong sunlight, which will cause the branches and leaves to wither and yellow.
Solution: move to a cool place.
4. Lack of light yellow: bamboo like warm, long-term shade in the environment, the plant growth is weak and then turn yellow. In winter, it is better to put it in a place with sufficient sun. If it is placed in a place with insufficient light, coupled with poor ventilation and cold, it is easy to cause withered and yellow branches and leaves.
Solution: add light to avoid the disease.
5. Fertilizer yellow: if the concentration is too high or the fertilizer is not yet decomposed, it is easy to burn seedlings. Even if the seedlings are dry and do not apply fertilizer for a long time, the fertilizer will turn yellow.
Solution: should immediately stop fertilization, serious with a large number of washing and washing part of the fertilizer.
6. Lack of fertilizer yellow: it is necessary to apply fertilizer regularly to Phyllostachys pubescens, so that it has enough nutrients. If the supply of nutrients falls short of demand, the branches and leaves will turn yellow.
Solution: check the soil in the basin, and change the soil if it is dry and dry. Usually, apply thin fertilizer frequently and pour some alum water at the right time.
There is also a reason for the yellow leaves is lack of iron. You can buy some ferrous sulfate and put it in the water according to the instructions. The simplest way is to find two small iron nails and put them in the water (preferably rusty nails)
Bamboo leaves yellowing, bamboo maintenance experience: 1, appropriate watering: every spring before the emergence of shoots (March) enough water to promote shoots, may and June water-saving. In rainy season, water can be watered according to rainfall, and in November and early December, it can be watered properly in winter when it is too dry. After planting bamboo, regardless of wind and rain, it should be drenched with bamboo and filled with soil. As with other seedling maintenance, root water should be drenched.
2. Soil loosening and weeding: it is carried out twice a year, the first in May and June, and the second in July and August before the seeds of weeds are mature.
3. Reasonable fertilization: in order to promote the regeneration of bamboo and early forest, fertilizer should be applied in time. The best fertilization time was March and August to September in early spring, and the effect of combining farm manure and chemical fertilizer was good. In autumn and winter, the application of organic fertilizer such as cake fertilizer and soil manure is beneficial to the overwintering of pregnant bamboo shoots. Application of human manure and chemical fertilizer in spring and summer can meet the needs of bamboo growth and development in time.
4. In addition, the cutting time should be reasonable, but the cutting time should be too fast. In thinning, we should leave the small and the big, the weak and the strong, the old and the young, and the dense and sparse. Every 3 to 5 years, the dense bamboo should be moved to maintain the appropriate density of bamboo forest to ensure ventilation and light transmission. At the same time, deep turning and breaking the whip are carried out to dig out the old rhizome which is more than four years old and the bamboo stump after cutting every year. Soil and miscellaneous fertilizer should be used to fill the pit in time to keep the forest land level.
5. Bamboo forest planning: under the condition of sufficient land use and landscape needs, the soil should be dug deeply in the direction of bamboo forest extension plan, and soil miscellaneous fertilizer should be applied to guide the extension of bamboo rhizome.
