Proud as a peacock flower cultivation method proud as a peacock flower cultivation method: fertilization.
In the peak season, we should apply 1 time of thin liquid fertilizer every half month. When applying fertilizer, we should pay attention to not applying too much nitrogen fertilizer, so as to avoid the phenomenon of poor growth such as fading of leaf stripes, thickening of leaves and soft petiole. Generally, the application ratio of nitrogen, phosphorus and potassium should be1:1:1. Soilless culture is adopted, and1~ 2 times of all-element inorganic nutrient solution is poured every month during the growth period.
When fertilizer is lacking, the plants are obviously short, the leaves are dim and the golden luster is not bright. Apply thin liquid fertilizer once every 20 days in the growth period, and the ratio of nitrogen, phosphorus and potassium should be 2∶ 1∶ 1, which can make the leaves bright and shiny, and avoid excessive proportion of nitrogen fertilizer. For example, spraying 0.2% liquid fertilizer directly on the leaves every 10 days is very beneficial to germination and growth. Stop rotating fertilizer in winter and summer.
Cultivation method of proud as a peacock flowers: temperature.
The optimum growth temperature of Arundo donax is about 22℃. When the temperature is higher than 35℃ in summer, not only the plant growth stops, but also the leaves turn yellow and lose ornamental value. In winter, when the temperature is lower than 15℃, the growth of the plant slows down, the leaves are easy to curl below 10℃, and the leaves are easy to be frozen below 5℃, which will lead to the death of the whole plant in severe cases. Therefore, we must pay attention to cold protection and heat preservation in winter, and the room temperature should be kept above 13℃.
Cultivation method of proud as a peacock flowers: illumination.
5? During the growing season in September, it should be placed in a shady or semi-shady place, and the light transmittance should be maintained at 40%-60%, so as to avoid direct sunlight. Excessive illumination or air drying may easily cause the leaf edge to be scorched and the leaf markings to be dull. However, the light should not be too weak. If it is placed in a dark room for a long time, the temperature is low and the light is insufficient, it will also grow weak, which is not conducive to the formation of leaf color and lose the unique metallic luster of leaf surface. Direct sunlight through glass is acceptable in winter.
Cultivation method of proud as a peacock flowers: soil
Potting should use loose, fertile, well-drained, slightly acidic loam rich in humus. Generally, it can be prepared by mixing 3 parts of humus soil, peat or sawdust 1 part, sand 1 part, and adding a small amount of bean cake as base fertilizer. It is forbidden to use sticky garden soil. When the basin is put on, the bottom of the basin is first padded with 3 cm thick coarse sand as a drainage layer to facilitate drainage.
Cultivation method of proud as a peacock flowers: moisture.
Sufficient water should be given during the growing period, especially in summer and autumn, in addition to keeping the basin soil moist, water should be sprayed on the leaves frequently to cool and moisturize; It requires high air humidity, preferably 70% to 80%; Avoid dry air and dry soil, but do not accumulate water. Water should be controlled after the end of autumn in order to resist cold and overwinter. Keep a dry environment in winter, and if it is too wet, the basal leaves will be yellow and scorched, which will affect their ornamental value.
During the growing period, the basin soil must be fully kept moist, and the basin soil should be watered if it is not dry, otherwise the leaves will easily curl and scorch. Water is often poured on the plant page in summer. Pay attention to the pot soil can not be too wet, otherwise it will cause root rot and even death.
Cultivation method of proud as a peacock flowers: humidity
The suitable air humidity is 70% ~ 75%, and the humidity requirement is higher when new leaves are sprouted. Therefore, water should be fully watered during the growing season to keep the soil moist, but no water can accumulate. In summer, spray water on the leaves 2 ~ 3 times a day, and spray water on the surrounding ground to humidify and cool down, so as to facilitate their growth. Water should be controlled in winter, and the pot soil can be slightly wet. The indoor air is dry in winter in the north. Besides spraying the leaves with water close to room temperature around noon during the day, it is best to put on a plastic film cover at night to keep warm and moisturize. In order to keep the leaves fresh, clean and radiant, you can gently scrub the leaves with clean water every half month.
There are few diseases and insect pests in flower control in proud as a peacock, but if the air is not well ventilated and dry, scale insect damage will also occur, so 1500 times dimethoate spraying should be used for control.
Control of leaf spot of peacock arrowroot
Leaf spot is yellow-brown. At the beginning of the disease, small yellow spots are formed near the edge of leaves or in the center of leaves, which gradually expand, deepen in color and turn yellow-brown. There are obvious halo around the spots. With the expansion of the spots, the leaves gradually dry up and shrink, so that they fall off and die. The pathogen is the spores of the semi-ignorant fungus Dermatomyces. The causes of the disease are high temperature and humidity, poor ventilation, too dense plants, too many weeds and rotten leaves in the cultivation environment, too much nitrogen fertilizer application, and plants grow in vain. Young tissue is easy to get sick.
The control method is to strengthen the management of fertilizer and water, appropriately increase the application of phosphorus and potassium fertilizer, and reduce the application of nitrogen fertilizer to promote the growth and enrichment of plants and enhance their own resistance. Remove diseased leaves and weeds in time to reduce the source of infection. Plant placement is not easy to be too dense, proper ventilation and light transmission can reduce the humidity of the environment, which can reduce the incidence. Spray protection when the disease occurs. The agents are: 50% carbendazim 600 times to 800 times; Or 600 to 800 times of 75% chlorothalonil; 500 times to 600 times of 50% mancozeb, once every 7 days to 10 days. Various drugs should act alternately to prevent bacteria from developing drug resistance.
Cultivation method of peacock arrowroot 1. Cultivation environment. Peacock arrowroot likes high temperature and humid environment, and has strong shade tolerance, and the appropriate illuminance is 30% ~ 40%. It grows well under indoor scattered light and should be cultivated in loose and fertile soil with good drainage. In spring and autumn, it can be maintained in bright indoor light, and in summer, it should be maintained in semi-shade. Excessive light will make the leaves yellow and scorch, which will affect their ornamental value. When the light intensity decreases in winter, the flowerpot can be moved to the south window for cultivation, and the growth environment should not be too shaded at this time. If it is placed in a dim place for a long time, the leaves of the peacock taro will lose their unique luster.
2. Growth temperature and moderation.
① temperature. The optimum growth temperature of Arundo donax is about 22℃. When the temperature is higher than 35℃ in summer, not only the plant growth stops, but also the leaves turn yellow and lose ornamental value. In winter, when the temperature is lower than 15℃, the growth of the plant slows down, the leaves are easy to curl below 10℃, and the leaves are easy to be frozen below 5℃, which will lead to the death of the whole plant in severe cases. Therefore, we must pay attention to cold protection and heat preservation in winter, and the room temperature should be kept above 13℃.
② Humidity. The suitable air humidity of peacock arrowroot is 70% ~ 75%, and the humidity requirement is higher when new leaves are sprouted. Therefore, water should be fully watered during the growing season to keep the soil moist, but no water can accumulate. In summer, spray water on the leaves 2 ~ 3 times a day, and spray water on the surrounding ground to humidify and cool down, so as to facilitate their growth. Water should be controlled in winter, and the pot soil can be slightly wet. The indoor air is dry in winter in the north. Besides spraying the leaves with water close to room temperature around noon during the day, it is best to put on a plastic film cover at night to keep warm and moisturize. In order to keep the leaves fresh, clean and radiant, you can gently scrub the leaves with clean water every half month.
3. Pot selection and fertilization.
1 choose a basin. The peacock arrowroot is a shallow-rooted plant, and the cultivation container should be a large mouth and shallow basin, which is beneficial to the elongation and stretching of the root system. Pot soil should be loose, fertile and well drained. 6 parts of peat soil (or humus soil), 2 parts of garden soil and 2 parts of sandy soil can be selected and mixed evenly. Can also be used soilless matrix, such as perlite, vermiculite half mixed preparation. Generally, the pots are changed at the turn of spring and summer when the ramets are propagated, and the pots are changed every two years 1 time.
② Fertilization. Thin liquid fertilizer should be applied 1 time every half month in the peak season of peacock arrowroot growth, and too much nitrogen fertilizer should be applied when applying fertilizer, so as to avoid the phenomenon of poor growth such as fading of leaf stripes, thickening of leaves and soft petiole. Generally, the application ratio of nitrogen, phosphorus and potassium should be1:1:1. Soilless culture is adopted, and1~ 2 times of all-element inorganic nutrient solution is poured every month during the growth period.
4. Reproduction. Peacock arrowroot is propagated by dividing plants, and it is combined with changing pots and soil in April-May in spring. Early branching, low temperature, slow wound healing, easy to cause rot and reduce survival rate. When dividing plants, the mother plants are buckled out of the pot, the soil is removed, and every 3-4 buds are cut into 1 plant with a sharp knife, and the incision is coated with charcoal powder for corrosion protection. After cutting, the mother plants are immediately put into the pot, watered with water, and placed in a semi-shady place to slow down the seedlings. After 5-7 days, they can be transferred to normal management. It is better to plant 3 ~ 5 plants in a pot when dividing plants. If only one plant is planted in each pot, it is necessary to keep more than 5 leaves and bring more roots, otherwise it will affect the survival and growth of the plant after survival.
5. Pest control. Peacock taro generally has few pests and diseases, but it should be ventilated to prevent scale insects from harming it.
