[knowledge of flowers and plants] knowledge that families must know to grow flowers

The knowledge of flower farming, especially the knowledge of growing flowers in the house, is very much. Let's learn some more necessary knowledge of growing flowers from three aspects below.

First, the health benefits of indoor plants

1. Clean air of drug abuse: some indoor plants can effectively absorb toxic chemicals produced by house decoration, such as Cymbidium, Magnolia, Magnolia, Phyllostachys pubescens, etc. on the other hand, goldfish grass, morning glory and carnation can convert highly toxic sulfur dioxide into non-toxic or low-toxic sulfate compounds through leaves. Iron tree, chrysanthemum, pomegranate, camellia can effectively remove harmful substances such as sulfur dioxide, chlorine, ether, ethylene, carbon monoxide, nitrogen peroxide and so on.

2. Don't get angry if you increase the humidity: generally speaking, the relative humidity in the room should not be less than 30%. If the humidity is too low or too high, it will have an adverse effect on human health. Planting some plants with high water requirements indoors, such as green pineapple, ivy, rhododendron, ferns and so on, will increase indoor humidity in a natural way and become a natural humidifier.

3. Natural vacuum cleaners: studies have shown that orchids, taros and cinnamon are natural dust collectors, and the cilia on their plants can intercept and absorb particles and smoke floating in the air. If there is a sufficient number of such plants in the room, the content of plankton and floating dust in the room will be reduced.

II. Matters needing attention for flower purchase in the flower market

1. See if the potted soil is too dry. In addition to drought-tolerant flowers, it is best not to choose potted flowers that are thoroughly dry. This is either kept for a long time by the florist or deliberately not watered by the florist in order to save costs or reduce the mortality rate of flowers and plants. Many flowers and plants are transported from the breeding base to the flower market over a long distance, and it is inevitable that there is a shortage of water, which will wither their roots and rot as soon as they are watered. The florist is not a fool, and this kind of stupid thing is best for buyers to do. Unwatered flowers and plants will have a false active period, be sure to pay attention when buying.

2. See if there are obvious signs of pruning the branches and leaves, and if so, consider that the shop owner has trimmed off the withered branches and leaves, leaving a good one to attract attention. Trunk thick flowers and plants, to carefully pinch the stem, see if there is hollow, peeling phenomenon, truncated woody flowers, depends on the head fracture healing, there is no decay or moth.

3, look at the bud, pay attention to buy more buds than flowers, buy back and watch for a longer time, and buds and flowers can not have scorched, drooping head phenomenon, bargain or do not buy.

Third, the method of cleaning flower leaves

1, the time to clean the leaves: the time to clean the leaves is in the morning, so that the leaves have sufficient drying time before the arrival of night, so as not to make the leaves in a humid environment due to the lack of sunshine and the decrease of temperature at night.

2. The method of cleaning the blade: A. The water spraying method uses the water impact force of the sprayer to wash away the dust on the blade. B, wipe the dust and sludge on the leaves repeatedly and gently with a sponge or cotton cloth dipped in water. C, brush method use a soft brush to clean the dust on the leaves.

3. Note: the first two methods are not suitable for cacti, succulent plants and plants with downy leaves. Once the leaves are wet by water, it is difficult to evaporate, even if the moisture is absorbed by a dry cloth, it can not be guaranteed to dry within a certain period of time. And some flower buds that are afraid of water, such as the flower buds of African chrysanthemum leaves and the false bulbs of magnolia leaves, should not be touched by water, especially in the germination and budding period, water will affect the development of flowers.

Of course, just mastering the relevant knowledge is not enough, after mastering the knowledge, we also have to learn to apply them flexibly in order to turn the knowledge we have learned into a tool to help us cultivate flowers and plants.
