Bottle Culture and Brown spot of Fugui Bamboo

The difficulty of raising rich bamboo can be said to be very low, and the methods of hydroponic culture and soil culture are very suitable, but do not think that the raising difficulty of rich bamboo is very low, it does not pay attention to the usual feeding, rich bamboo will also get sick. The editor will give you a detailed analysis of the method of bottle culture of rich bamboo and the brown spot of rich bamboo. Friends who want to raise rich bamboo can learn.

Rich bamboo

First, the bottle culture method of rich bamboo.

1. Before entering, the leaves at the base of the cuttings of Fugui bamboo should be cut off, and the base of Fugui bamboo 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 the water every 3-4 days, do not move the rich bamboo position or change the direction of the rich bamboo within 10 days, about 15 days can grow silver white fibrous roots.

2. Water-fed rich bamboo should not change water after rooting, and water can be added in time only after water evaporation is reduced. Frequent change of water is easy to cause rich bamboo leaves and yellow branches to wilt.

3. After water-fed rich bamboo takes root, a small amount of compound fertilizer should be applied in time, the leaves will be oil-green and the branches will be stout. If there is no fertilization for a long time, the growth of rich bamboo plants is thin, and the leaf color of rich bamboo is easy to yellowing. However, fertilization can not be too much, so as not to cause "burning roots" or cause overgrowth. Compound fertilizer can be applied once a month in spring and autumn. According to the data, in order to prevent excessive growth, do not apply chemical fertilizer, it is best to inject a few drops of brandy into the bottle every 3 weeks or so, adding a small amount of nutrient solution, that is, the leaves of rich bamboo can keep green.

4. Do not put the rich bamboo next to the TV set or the air conditioner or electric fan, lest the leaf tip and edge of the rich bamboo will dry up.

2. Brown spot of Fugui bamboo

1. Symptoms

Brown spot mainly harms the leaves, when the disease occurs, there are straw-yellow wet spots on the leaf edge and leaf tip, and there are light brown round or long oval to long disease spots at the junction of the disease and health, which are parallel to the leaf veins, and the symptoms of the old leaves are especially obvious. Leaf edge, leaf tip disease spot length 7 to 13 cm, width 1 to 2 cm, severe symptoms of disease spot length 13 to 15 cm, and with brown markings, leaf disease spot expansion, into brown macula, plant growth is affected, reducing ornamental value.

2. Pathogen and occurrence regularity

The pathogen of the disease is a kind of microorganism called Cercospora, which overwinters on the diseased part or diseased body. In the spring and summer of the second year, conidia are transmitted through wind, rain, air and water splashing, and multiple infections and re-infections can occur. The disease is easy to occur when the humidity is high, and it can occur from seedling stage to adult plant extension stage. The optimum temperature for germ germination is 25 to 28 ℃. High temperature and humidity are beneficial to the propagation, transmission and invasion of pathogens, and are easy to occur in rainy and low-lying areas in spring and summer. In the Pearl River Delta, the disease is more serious from April to September, and when it is hot and dry in summer and autumn, sudden thundershowers or typhoon rainstorms can easily lead to serious disease.

3. Prevention and control methods

(1) keep the field and basin soil moist, pay attention to drainage during rainfall in summer and autumn, and increase the application of phosphorus and potassium fertilizer and compound fertilizer; in winter, water and fertilizer should be controlled to promote dormancy, spray to kill bacteria, or cut off diseased and withered leaves and burn them.

(2) spraying 50% carbendazim wet powder, 50% methyl thiophanate and sulfur suspension, 50% carbendazim powder, 50% Wanning wet powder, 50% methyl thiophanate wettable powder, 50% carbendazim, 50% carbendazim, 70% chlorothalonil + 40% generation of Shangle (1 ∶ 1) wettable powder, alternately sprayed 3 to 4 times, once every 7 to 8 days, has a better control effect.

The popularization rate of rich bamboo is very wide, and we can often see them in our daily life, but the bottle culture of rich bamboo is not so common in daily life. in fact, the difficulty of raising rich bamboo in bottles is very low. and you can keep it well. If you find that your rich bamboo is sick, you should pay attention to treatment, even if the rich bamboo, a very adaptable plant, will die if it is cured.

Control methods of Brown spot of Fugui Bamboo

Rich bamboo (scientific name: Dracaena sanderiana), alias bamboo banana, bamboo, open bamboo, rich tower, bamboo tower, tower bamboo. In the Wenchang position, it is also called Wenchangzhu (usually 4). It belongs to the genus Liliaceae. Native to Cameroon in western Africa. As a perennial evergreen herb, it is mainly used as a potted ornamental plant with high ornamental value and symbolizes "good luck", hence the name. After 1970, it was introduced into China for ornamental use. Now it is a common ornamental plant in China, and it is also popular in the international market.

Rich bamboo as a commercial ornamental, cultivation height of 80cm 100cm is appropriate, more cultivated in the garden, like wet, thick stems and leaves, its varieties are green leaves, green leaves white edge (called silver edge), green leaf yellow edge (called Phnom Penh), green leaf silver heart (called silver heart), mainly for pot ornamental plants, stem nodes look like bamboo but not bamboo.

Rich bamboo brown spot, symptoms: the main harm to the leaves, the leaf edge and leaf tip appeared straw yellow wet disease spot, at the junction of the disease and health there are light brown round or long oval to long disease spot, parallel to the leaf vein, the symptom of the old leaf is especially obvious. Leaf edge, leaf tip disease spot length 7 to 13 cm, width 1 to 2 cm, severe symptoms of disease spot length 13 to 15 cm, and with brown markings, leaf disease spot expansion, into brown macula, plant growth is affected, reducing ornamental value. Pathogen and occurrence regularity: the pathogen of the disease is a kind of microorganism called Cercospora, which overwinters on the diseased part or diseased body. In the spring and summer of the second year, conidia are transmitted through wind, rain, air and water splashing, and multiple infections and re-infections can occur. The disease is easy to occur when the humidity is high, and it can occur from seedling stage to adult plant extension stage. The optimum temperature for pathogen germination is 25 to 28 ℃. High temperature and humidity are beneficial to pathogen breeding, transmission and invasion, and are easy to occur in rainy and low-lying areas in spring and summer. In the Pearl River Delta, the disease is more serious from April to September, and when it is hot and dry in summer and autumn, sudden thundershowers or typhoon rainstorms can easily lead to serious disease. Control methods: (1) keep the field and basin soil moist, pay attention to drainage during rainfall in summer and autumn, increase the application of phosphorus and potassium fertilizer and compound fertilizer, control water and fertilizer in winter, promote its dormancy, spray to kill bacteria, or cut off diseased and withered leaves and burn them. (2) spraying 50% carbendazim wet powder, 50% methyl thiophanate and sulfur suspension, 50% carbendazim powder, 50% Wanning wet powder, 50% methyl thiophanate wettable powder, 50% carbendazim, 50% carbendazim, 70% chlorothalonil + 40% generation of Shangle (1 ∶ 1) wettable powder, alternately sprayed 3 to 4 times, once every 7 to 8 days, has a better control effect.
