Several reasons for nourishing rich bamboo leaves with water 1. Burning yellow, strong sunlight shines directly on some shade-loving flowers (such as chlorophytum and Hosta). ), it is easy to cause the tip of the leaf and the edge of the leaf to wither, and yellow spots appear in the sunrise part of the leaf. Move to the shade. 2. Leaves exposed to light yellow for a long time can't get enough sunlight to form chlorophyll, and the whole leaves turn yellow and then fall off. Supplementing light can avoid this disease. 3. The yellowing of flowers caused by excessive fertilization or high concentration of fertilizer yellow shows that the top of new leaves is yellow, generally thick, dull, concave and convex, and the old leaves are brown and fall off. Fertilization should be stopped immediately, and some fertilizers should be washed carefully with a lot of cleaning. 4. The lack of fertilizer yellow shows that the color of young leaves turns pale, yellow or light green, and the old leaves turn normal or gradually from green to yellow. Check the soil in the basin, change it when it is dry, apply thin fertilizer frequently at ordinary times, and pour some alum water in time (Fu Guizhu is a nitrogen-based fertilizer used for foliage plants). Fu Guizhu's water lifting skills Fu Guizhu should master the following points when lifting water in a bottle: 1. Before entering, the leaves at the base of the cuttings should be cut off, and the base should be cut into an oblique mouth with a sharp knife, and the incision should be smooth to facilitate the absorption of water and nutrients. Change clean water every 3 -4 days 1 time, 10 day keeps the same direction, and 15 day grows silvery white fibrous roots. 2. It is not advisable to change water after rooting, and water can be added in time after water evaporation is reduced. Changing water frequently can easily lead to yellowing of leaves. 3. After rooting, apply a small amount of compound fertilizer in time to make the leaves oily green and the branches stout. If fertilization is not applied for a long time, the plants will grow very thin and the leaves will turn yellow easily. However, fertilization should not be too much, so as not to cause "root burning" or ineffective growth. Apply compound fertilizer l times a month in spring and autumn. According to the data, in order to prevent overgrowth, it is best to inject a few drops of brandy into the bottle every three weeks or so and add a small amount of nutrient solution to keep the leaves green. 4. Don't put the rich bamboo beside the TV or on the ground where air conditioners and electric fans often blow, so as to avoid the dry tip and edge of leaves. Your hydroponic bamboo leaves turn yellow, which can be found in the following two aspects: First, check the water quality, mainly to see whether the roots are fresh. If the root rot is caused by water quality, it is necessary to switch to cold boiled water. Second, check the lighting conditions of the place, such as too dark light, stuffy and stuffy, dry air and so on. Will cause the leaves to turn yellow; However, if the light in the place is too strong, it will also lead to yellowing of the leaves and absence. What about the yellow-leaf bamboo? If it is caused by light, you can cut off the yellow leaves and the rotten roots first, and then create a clean, temperate, cool, humid and evenly distributed environment for it. If the root rot is caused by unclean water, you can cut off the yellow leaves first. When the symptoms are not serious, change the water frequently and put it in a ventilated and sunny place for restorative maintenance. When the symptoms are serious, pesticide should be sprayed properly or a small amount of bactericide should be added to the water tray. Other questions "the yellow leaves of your rich bamboo may be caused by low temperature." It is evergreen woody, likes high temperature and high humidity environment, and is also resistant to shade and waterlogging, and has certain cold resistance. When the temperature is lower than 10℃ in winter, the leaves will turn yellow and fall off. As indoor ornamental plants, generally no nutrients are added to the soaking solution of Phyllostachys pubescens to prevent the stem nodes from rotting. It is best to use tap water or cold boiled water for overnight storage. Change it every 65,438+08 days to 65,438+05 days, and change it every 5 to 7 days in summer, but only pour out half and add a new half each time, otherwise the root system will not adapt. If you want to keep the hydroponic bamboo growing, you can add a small amount of urea and potassium dihydrogen phosphate aqueous solution to the soaking solution, the concentration can be controlled at about 0. 1%, and change it once every half month, or you can spray the fertilizer solution on the leaves. When more new buds grow, the diseased buds and dyed buds should be cut off as soon as possible, otherwise the whole pot of rich bamboo will be damaged; On the premise of not affecting the overall shape and appreciation of Fu Guizhu, it is also necessary to carry out adaptive thinning. Add a quiet, warm and happy atmosphere. Not only the temperature is low, the air humidity is low, but also it is dry. Fu Guizhu originated in the Canary Islands and tropical regions of Africa and Asia, and is now widely introduced and cultivated in China. Its nature likes high temperature and high humidity environment, has low requirements for light, and is also resistant to shade. Suitable for growing in sandy loam with good drainage. The optimum growth temperature is 20~30℃, and the overwintering temperature is 65438 00℃. Fu Guizhu is propagated by cutting. Pruning is combined with plastic pruning. As the plant grows taller, the leaves at the base of the stem often fall off, and the plant deformation is poor. In the growing season, the stems can be cut into 5- 10 cm as cuttings, or vermiculite or river sand. Generally, it can take root and sprout in 1-2 weeks. Potted bamboo can be planted with humus soil, garden soil and river sand in the same amount, or with coconut bran and humus soil and a small amount of base fertilizer as cultivation soil. The key to management is to master humidity and temperature. During the growing period, the basin soil should always be kept moist, and the leaves should always be sprayed with water to maintain a high environmental humidity. If it is too dry, the nib will dry up. Pot soil should not be too wet in winter, but water should be sprayed on the leaves frequently, and at the same time, attention should be paid to cold protection to prevent the leaves from yellowing, shrinking or even falling off. In May-September, liquid fertilizer or granular compound fertilizer is applied 2-3 times a month to keep the leaves green and bright. The requirements for illumination are not high, and it is suitable for growth under bright scattered light, and direct sunlight should be avoided. If exposed or dried in the sun, the leaves will be rough, scorched and dull, which will reduce the ornamental value.
