[can cactus be raised in water] can cactus be raised in water?

Cactus is a very easy to raise plants, do not need how to water, will not die of drought, but if the cactus uses hydroponics, what should be paid attention to, how can hydroponic cactus be raised well?

How to cultivate hydroponic cactus

How to raise the hydroponic cactus 1. Choose the female parent

First of all, we should choose the cactus with a strong sphere, and the key is to select the plant with the lower rhizome protruding downward. The cactus grafted with Mitsubishi sword is easier to be hydroponically cultured.

After selecting the female parent, the original dead root under the sphere is completely cut off, and the cut mouth is required to be flat. Then rinse the soil attached to the rhizome with clean water and dry it in a dry place for 3 days to make the incision completely dry. It is necessary for cactus mutagenesis to remove native roots. Because the cactus is a succulent plant, before induction, drying for a period of time is more beneficial to root, because succulent plants have more stringent requirements for water in the seedbed, too much is easy to rot, and too little causes the effect of root.

In terms of effect, it is the nutritional stress caused by clear water, which can accelerate the formation of root aeration tissue and the development of aquatic roots, but from the point of view of cultivation, it is better to use appropriate concentration of nutrient solution in water, which is related to the fertilizer tolerance of mutated plants.

Prepare a glass bottle of the right size, or use a mineral water bottle. Transparent utensils are easy to observe the contact surface between the liquid surface and the rhizome. Use flower mud or foam to fix the cactus with flower mud or foam at the mouth of the bottle. Add the nutrient solution below, and the height of the nutrient solution just touches the rhizome. Prepare foam jigsaw puzzle plates or white building foam boards for children's play, dig several triangular holes with sharp knives on the layout (the golden tiger can be fixed by cutting off the mouth of the waste pure water bottle and use it upside down. Note: cut off the bottle mouth so that the root of the golden tiger can be exposed from the cut bottle mouth, and then placed in a flat body with nutrient solution) insert the Mitsubishi sword into the triangle hole At this time, the roots of all Mitsubishi swords just touch the liquid surface.

Ammonia-free nutrient solution is most suitable for co-culture of fish and flowers, otherwise it will kill the fish.

When hydroponically cultured cactus, the water level should not exceed 1 / 2 of the root.

Buy two magnets with a diameter of 6-10cm and put them into utensils in order to magnetize the nutrient solution and speed up the formation of aquatic roots. (if possible, a small suction wall submersible pump for ecological fish tank can also be purchased from the market, which can be adsorbed on the inner wall of the nutrient solution and electrified to realize the flow and oxygen circulation of the nutrient solution.

Maintenance technology of cactus

The temperature cactus likes high temperature and dry environment. In winter, the room temperature should be kept above 20 ℃ during the day and not less than 10 ℃ at night. Too low temperature is easy to cause root rot, but if the temperature is too high, it is easy to cause the harm of scale insects.

Light cactus requires plenty of sunshine, but it can not be exposed to strong light in summer and needs to be properly sheltered. Indoor cultivation, can be illuminated by light to make it grow healthily.

Soil cactus is suitable for the growth of sandy loam soil with good drainage, and artificial culture soil is often selected for indoor cultivation, which is usually mixed with peat soil and fine sand, and can also be planted with crushed pine needles mixed with fine sand.

Watering cactus requires a dry environment, afraid of basin soil stagnant water, usually to keep the basin soil "dry and wet". It is best to use dried water. It should be watered once a month in spring and summer and once every 2-3 months in winter. when watering, be sure to water the cactus thoroughly to change the soil, apply a small amount of base fertilizer to the bottom of the basin, such as horseshoe slices, bean cakes or sesame sauce dregs. During the growing period, the fermented organic fertilizer liquid fertilizer should be irrigated every semimonthly (the concentration should be 20%), and the fertilizer concentration should not be too high.

Cactus can be grafted and propagated, generally using the method of parallel grafting, and the rootstocks can choose trigonous arrows or robust palms. The specific methods are as follows: first, cut off the top of the rootstock, cross-cut the base of the scion, butt the two, and then tie them with string. After two weeks, the rope can be removed.

The aging of the cactus starts from the bottom. When the aging yellow appears, using a brush to smear the unwatered Yunda 120 times can make the yellow fade and rejuvenate the cactus. This is my experience. Yunda 120 is a plant growth regulator containing hormones, which is harmless to the ball at high concentrations. It has less reaction than other plant growth regulators.

Hydroponic cactus needs to change water and clean flower roots:

Hydroponic plants can change water about 7 days in summer and 15 days in winter, and a few drops of special nutrient solution for hydroponic flowers can be added (the concentration of nutrient solution is prepared according to the instructions). The utensils used to cultivate hydroponic plants are easy to grow moss, affect the ornamental of the roots, and consume oxygen in the water. When changing water, you should first wash away the mucus from the flower roots with clean water, and cut off the old and rotten roots. And wash the moss on the utensils and roots. For each change of water, the interface of the water is suitable for the submerged root system, and the rest of the root segment is allowed to be exposed to the air.

Hydroponic cactus needs to be moisturized and sprayed with foliar fertilizer:

In order to prevent the occurrence of leaf dryness, spraying foliar moisturizing with clear water during daily nursing, it is best to spray foliar fertilizer once a week, which can not only provide nutrition for leaves, increase foliar luster, but also resist low temperature in winter.
