What are the key points of cactus hydroponics?

Cactus is a familiar succulent plant, also known as grass ball, Changsheng pill and so on. The cactus is very resistant to drought because it was born in the desert. It has a wide variety and has high ornamental value. Cactus will also blossom, there are still many colors, usually in the morning or evening. Now many people will put the potted cactus on the balcony, office, etc., play a good role in embellishing the environment. In addition to soil culture, cactus can also be cultured in water. Let's take a look at the main points of its hydroponic culture methods.

I. the hydroponic culture method of cactus

1. Choose a healthy cactus, cut off its dead roots, wash it with clean water and then dry it, and put it in a nutrient solution that does not exceed the 1/3 water level of the basin.

2. Buy two magnets, no more than ten centimeters in diameter, and put them in a cultivation vessel so that the culture medium can be magnetized and the root growth can be promoted.

3. Put the planted cactus in an environment with astigmatism, the temperature had better not be less than 20 degrees Celsius, and it will take less than a week to take root. After taking root, there is a step that can not be omitted, that is to change the nutrient liquid in time.

In the whole process of cactus mutagenesis, it is best not to spray water on it, otherwise it is easy to rot the cactus, resulting in the death of the whole cactus.

2. Daily maintenance points of cactus after hydroponic culture

1. Temperature management

The hydroponic temperature of cactus should be controlled between 5 and 30 degrees Celsius, which is the best temperature for its growth and is also suitable for the growth of other hydroponic plants.

2. Lighting conditions

Many people mistakenly think that the cactus needs to be exposed to strong light in order to survive, but in fact, it only needs a certain amount of astigmatism, not necessarily to the sun. Especially in the summer with strong light, direct sunlight is not allowed, otherwise there will be a burning phenomenon, so that the whole plant yellowed or died.

3. Clean the roots regularly

Hydroponic cactus must clean the roots regularly, especially in the hot summer, usually change the water once a week. In winter, you can appropriately prolong the time of changing water, even once every half a month. After changing the water, a special nutrient solution for cactus should be added to trim off the rotten, cut, and aging roots.

Each time you change the water, you only need to submerge 1/3 of the root.

4. Spray leaves to keep moisture.

On weekdays, you can properly spray leaf water to increase air humidity and leaf humidity, so as to achieve the effect of glossy leaves.

To sum up, whether hydroponic cactus or soil cactus, follow-up maintenance can not be separated from watering, fertilization, temperature, light and other conditions, so we must take good care of it.
