Detailed introduction of the methods and principles of watering Cymbidium

The gentleman orchid likes the wet soil environment. But the watering is too much, the basin soil is too wet, and the air in the soil is squeezed out. Let's take a look at the detailed introduction of the methods and principles of gentleman orchid watering.

Detailed introduction of the methods and principles of watering Cymbidium

If the lack of water exceeds a certain limit, the plant will wilt or even die. It doesn't work if you water too much, and even if you don't dare to water, so some people use the term "growing flowers for three years" to describe the difficulty of watering. So how to water the magnolia?

(1) the combination of penetration and non-penetration

Don't water it every time, and don't keep it dry all the time. Only replenish the surface water when there is a shortage of water on the surface, and pour water through it when the water content of the bottom layer is insufficient.

(2) combination of dry and wet

The soil should always be in a dry-half-wet-wet state (note that the soil water content should not be less than 30% when dry), which is conducive to the survival of aerobic and anaerobic microorganisms in the basin soil and is conducive to the growth of Magnolia.

(3) combination of water and fertilizer

Add a little liquid fertilizer every time you water, which not only helps to improve the water quality, but also is very beneficial to the growth of Magnolia.

(4) the combination of spraying and spraying

When the family is cultivated, the surface layer of basin soil is often easier than that in greenhouse and cellar. If it is irrigated with heavy water, it is often too large and urgent to irrigate either uneven or impermeable water. The applicable method is that when the plant does not need to be watered, a spray can with pressure can be used to wet and spray through the surface of the basin soil. When you need to pour water thoroughly, you can use a special sprinkler (there are many small holes in the spout) to sprinkle water evenly to every part of the basin soil, so as to achieve the best effect of watering.

(5) the combination of top and bottom

When the orchid needs to be watered thoroughly, the flowerpot can be placed in a large basin with a certain amount of water, so that the water in the basin can slowly seep into the basin soil through the hole at the bottom of the basin. If you want to speed up the watering, you can use small utensils to irrigate the water in the basin from above. After pouring thoroughly, drain the water from the basin. Families that raise a small number of orchids can use this method.

What kind of water is good for gentleman orchids?

(1) hard water

Water is divided into hard water and soft water according to the amount of salt. There are many salts in hard water. Watering Cymbidium with hard water containing a large amount of calcium and magnesium mineral salts for a long time will make the basin soil of Cymbidium become alkalized and become poor permeability, causing brown spots in the leaves of Cymbidium plants, affecting the ornamental effect, or toxic symptoms such as dry tip, chlorosis, yellowing and shedding of leaves, seriously affecting plant growth and flowering, so it is best not to use hard water for watering.

(2) soft water

Rain Water (or snow water) is the most ideal in soft water. Because Rain Water is a kind of near neutral water, does not contain minerals, and has more air (the suitable pH value of Cymbidium is 6.0-7.0), it is very suitable to use Rain Water to water Cymbidium. If Rain Water can be used for a long time to water Magnolia, it will help to promote the assimilation of Cymbidium, prolong the cultivation life and improve the ornamental value. Therefore, we should try to store more Rain Water for use in the rainy season. In the areas south of the Yangtze River basin with snow, snow water can also be stored to water the magnolia, and the effect is also very good. However, it should be noted that the ice and snow should be melted and shelved until the water temperature is close to room temperature before use.

(3), river water, pond water

The main source of pond water is Rain Water. On rainy days, the parabolic running water is concentrated in the pond, so the pond water contains more nutrients. If you can water the magnolia with pond water for a long time, without fertilizer, the orchid will grow strong, bright leaves and bright flowers. Although the river comes from a wide range of sources, it is also dominated by Rain Water, which is also good for watering gentleman orchids. But the river is not as good as the pond.

(4) Tap water

After disinfection and precipitation, urban tap water has low hardness and contains less impurities. although it contains a small amount of volatile chloral chemicals, it still has high safety and reliability for Cymbidium. It would be better to leave it open for a few days until the chlorine in the water is volatilized.

(5) groundwater

Groundwater (well water, underground mineral water), generally high hardness, high salinity, contains a variety of impurities, sometimes contains more chlorine, should not be directly used to water magnolia. However, such as pre-storage and exposure, so that mineral precipitation, chlorine volatilization, can also be used to water the magnolia.

(6) Magnetic water

Recently, it has been reported that pouring magnetic water on Magnolia is very effective. The water temperature is close to the soil temperature, and it is suitable for about 20 ℃ in the spring and autumn rainy season. Pouring Magnolia with magnetic water can promote the metabolism of the plant, make the orchid grow vigorously, produce green leaves and flowers, and have the effect of preventing leaf spot.

(7) domestic wastewater

Domestic wastewater includes laundry water, dishwashing water, vegetable washing water, face washing water, tea water, rice washing water, blood sewage and so on. Some people always make a fuss about this waste water, in fact, it does more harm than good. Especially when planting flowers on the balcony, it is better to be clean and sanitary, and it is best not to water the magnolia with waste water. Gentleman orchid also cannot use laundry water containing soap or washing powder and dishwashing water containing oil, which is toxic.

What are the principles of watering magnolia

(1) look at the soil watering

You can usually flick the basin wall with your fingers. if you make a voiced sound, it means that the soil is wet and does not need watering; while if you make a light sound, it means that the basin soil is dry and should be watered. You can also look at the color of the soil for watering. When the basin soil is gray and white, it means that the soil is dry and needs watering; when the soil is dark, it does not need watering.

(2) watch the weather watering

When the temperature is high or the wind is strong, the plant evaporation is large, so it should be watered more; when the temperature is low or cloudy, it can be watered less; on rainy days, it is no longer watered. Sometimes when there is too much rain or Rain Water is too big, it still needs to be covered so as not to flood the potted flowers.

(3) watching seedling watering

New pots, new pots, newly planted magnolia, big seedlings watered thoroughly; young seedlings watered again two or three days later. Water again every 5 to 7 days.

(4) look at the basin watering

The new basin is dry and absorbs water quickly, so it should be watered more; the old basin is moist and does not absorb much water, so it should be watered less; the tile basin should be watered more, and the glazed basin and purple sand basin should be watered less; the big basin should be watered less, and the small basin should be watered frequently.

(5) look at the time to water

It is best to have a good effect before sunrise, after sunset, especially after sunset, especially in hot summer. Watering in the afternoon, the temperature is low, evaporation is small, gentleman orchid can absorb some more. Watering at noon, due to the drastic change of temperature, is easy to cause root damage and poor growth. In fact, the specific watering time of gentleman orchid as long as according to the specific situation, flexible control on the line.

(6) look at the temperature of the water

Watering requires that the water temperature is basically the same as the air temperature, and the difference between the water temperature and the air temperature is too big (more than 5 ℃), which is easy to harm the root system of Cymbidium. In order to reduce the damage of water temperature to the root system of Cymbidium, it is best to put the water in a bucket (tank) and dry in it for several hours, and then use it when the water temperature is close to the air temperature. Generally speaking, the water temperature suitable for watering magnolia is several degrees higher than the soil temperature in winter and several degrees lower than the soil temperature in summer. It is best to be close to or equal to the soil temperature in spring and autumn, and about 20 ℃ is suitable.

Gentleman orchid also cannot use laundry water containing soap or washing powder and dishwashing water containing oil, which is toxic.
