First, the cultivation method of peacock arrowroot

1, culture environment

Peacock taro likes high temperature and humidity environment, and has strong shade tolerance, and the suitable illumination is 30% ~ 40%. It grows well under indoor scattered light and should be cultivated in loose and fertile soil with good drainage. It can be placed in indoor strong light in spring and autumn, and it should be placed in semi-shade in summer. 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 cool at this time.

2. Growth temperature and humidity

① Temperature: The optimum growth temperature of peacock arrowroot is about 22℃, so we must pay attention to cold protection and heat preservation in winter, and keep the room temperature above 13℃.

(2) Humidity: The suitable air humidity of Peacock taro is 70% ~ 75%, and the humidity requirement is higher when new leaves germinate. Therefore, it is necessary to fully water the soil during the growth period to keep the soil moist, but not to accumulate water. In summer, the leaves are sprayed with water 2 ~ 3 times a day, and the surrounding ground is sprayed with water to humidify and cool down, which is beneficial to their growth. Water should be controlled in winter, and the soil can be slightly wet.

3. flowerpot selection and fertilization

① Selection of pots: the peacock arrowroot is a shallow-rooted plant, and the cultivation container should be a large-mouth shallow pot, which is beneficial to the elongation and stretching of roots. Potted 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 use soilless matrix, such as perlite, vermiculite semi-mixed preparation. Generally, in spring and summer, the pots are changed every two years 1 time.

② Fertilization: Dilute liquid fertilizer should be applied 65,438+0 times every half month in the peak season of Peacock taro, and too much nitrogen fertilizer should not be applied. Generally, the application ratio of nitrogen, phosphorus and potassium should be 65,438+0: 65,438+0. Soilless culture was adopted, and 1 ~ 2 times of total element inorganic nutrient solution was poured every month during the growing period.

4. reproduction

Peacock arrowroot is propagated by plants, and pots and soil are changed in April-May in spring. When dividing plants, the mother plant is buckled out of the pot, and the soil is removed. Every 3-4 buds are cut into 1 plant with a sharp knife, and the incision is coated with carbon powder for anticorrosion. Immediately after cutting, put the mother plant into a pot, water it, and put it in a semi-shady place to slow down the seedlings. It can be transferred to normal management after 5-7 days. It is advisable to divide plants into 3 ~ 5 plants in a pot. If only one plant is planted in each pot, it is necessary to leave more than 5 leaves and bring more.

Second, matters needing attention

Peacock taro likes high temperature and humid air and grows fastest above 20℃. In the low temperature season from 10 to April of the following year, the northern part should be moved into the greenhouse for wintering, and the wintering temperature should not be lower than 15℃. If the indoor temperature difference between day and night is large, you can cover the basin with plastic film or use a glass box to keep warm and moisturize, and wash the leaves with warm water once a month. Every spring, when the temperature rises to 20℃ steadily, you can change the pot once. When changing pots, new culture soil should be added, residual roots and leaves should be cut off and replanted to facilitate growth.

Morphological characteristics of peacock arrowroot

The peacock arrowroot plants are densely clustered, tall and 20-60 cm high. Petiole is purplish red, growing from rhizome. The leaves are thin leathery and oval, with a length of 10-20cm and a width of 5- 10cm. It is yellow-green, and the surface of the leaves is green with a faint metallic luster, bright and gorgeous. The two sides of the main vein are alternately arranged, and the long oval velvet stripes with pinnate dark green on the back are called purple, which is opposite to stripes.

The leaves have sleep movement, that is, at night, the leaves extend upward from the leaf sheath to the leaves, fold together with the stems, and unfold again after sunshine in Rosty Yi.
