Guidelines for the conservation of canna with the function of monitoring sulfur dioxide

Canna is native to tropical America and subtropics, alias red banana, orchid banana, tiger banana, broken blood red and so on. It has the function of monitoring sulfur dioxide with high ornamental value. Next, let's take a look at the canna conservation guidelines.

1. Monitoring function

Canna can remove and monitor the damage caused by harmful gases such as sulfur dioxide and chlorine, and issue warnings. When it is found that its leaves turn green and turn white, flowers and fruits fall off, we should pay special attention to chlorine pollution.

2. Maintenance guidelines

(1) Light

Adequate sunlight is required during the growing period, and be sure to receive at least 5 hours of direct sunlight every day. The environment is too dark and lack of light, which will delay the flowering period.

(2) temperature

Canna prefers higher temperature, and the optimum temperature for growth is 15-28 ℃. If the temperature is below 10 ℃, it is disadvantageous to its growth.

(3) watering

Canna can tolerate stagnant water for a short time, but it is afraid that too much water will easily lead to root rot. Canna should be watered frequently when it is just planted, once a day, but the amount of water should not be too much. During drought, more water should be sprayed on branches and leaves to increase humidity.

(4) fertilization

Sufficient base fertilizer should be applied to the soil before planting, and fertilizer should be applied frequently during the growing period. When the plant has 3-4 leaves, liquid fertilizer should be applied every 10 days until it blossoms.

(5) Reproduction

Canna can be propagated by sowing method or plant division method.

(6) pruning

Cut off the unfinished flowers as soon as possible after flowering, so as to reduce the cost of nutrition and promote the plants to continue to sprout new flower branches. after Frosts Descent in various parts of the north, if the canna is frosted, the exposed parts of the canna will all wither and yellow. at this time, the withered and yellow part of the ground should be cut off, dug out the rhizome, slightly dried and buried in the house with sand, and then replanted the following spring.

(7) arrangement and arrangement

Canna can be planted directly in the courtyard for appreciation, or in wooden buckets or large flowerpots, placed in living rooms, balconies, rooftops, corridors, and so on.

Guidelines for the conservation of azaleas with the function of "monitoring ammonia"

Rhododendron, also known as Yingshanhong and rhododendron, is one of the top ten famous flowers in China with high ornamental value. And it has the function of monitoring toxic gases. Let's follow the editor of Huinong Network to learn the guidelines for the conservation of azaleas.

1. Monitoring function

Rhododendron is highly resistant to harmful gases such as ozone and sulfur dioxide. at the same time, it can also absorb these harmful gases and purify the air. It is also very sensitive to ammonia and can be used as a monitoring plant.

2. Maintenance guidelines

(1) Light

Rhododendron is a long-day flower, even in the middle of summer, it should not be placed in the shade, but in a ventilated and cooler place, that is, outdoor shade. At the end of September and the beginning of October, the sun intensity weakens and the weather is cool, so the shading time should be shortened step by step in order to put it on the southeast balcony in front of the house.

(2) temperature

Move out of the greenhouse in mid and late April and put it in the leeward to the sun, shade in summer, or under the tree to avoid strong direct sunlight. The suitable temperature for growth is 15-25 ℃, and the highest temperature is 32 ℃. It began to move indoors in the middle of October, put it in a sunny place in winter, keep the room temperature at 5-10 ℃, and the lowest temperature should not be lower than 5 ℃, otherwise it would stop growing.

(3) watering

It is necessary to water more and water frequently in summer, because of the high temperature, strong sunshine and fast evaporation of water in summer. Water should be fully watered in the morning; watering at night depends on the situation, and the leaves should be sprayed to keep the leaves clean and the environment moist.

(4) fertilization

In the late winter and early spring every year, it is best to apply some organic fertilizer to the cuckoo as base fertilizer. After the rhododendron blossoms from April to May, because the plant consumes a lot of nutrients during the flowering period, the new shoots grow with the germination of leaf buds, which can be fertilized every 15 days or so. After the ambush, most of the shoots have stopped growing, at this time is the high temperature season, the physiological activity is weakened, can no longer topdressing. After autumn, the climate is getting cooler, and there is continuous autumn rain, temperature and humidity is suitable for cuckoo growth, at this time can do the last fertilizer, generally not suitable for fertilization after winter.

(5) pruning

Pruning is an important measure in daily maintenance and management, which can regulate the growth and development and make the growth exuberant. Daily pruning needs to cut off a small number of diseased branches and weak old branches, combined with the crown shape to cut off some overdense branches to increase ventilation and light, which is beneficial to plant growth.

(6) pick the heart

In the bud stage, buds should be picked in time to concentrate the supply of nutrients and make the flowers big and colorful.

(7) layout

Potted plants should not be placed on the ground, but should be placed on flower racks or inverted flowerpots, with shade nets or curtains hanging on them, and should be maintained.

The above is the monitoring function and maintenance guide of azaleas arranged by Huinong net Xiaobian. Have you learned it? Azaleas are not only beautiful but also have monitoring functions. Friends who like to grow flowers should not miss them.
