Propagation method of cactus how to sow cactus

Cactus is light-loving, drought-resistant and easy to feed. For novice flower growers, planting a pot of cactus is the first choice. Many people don't know how it propagates. So what are the breeding methods of cactus? How to sow the cactus correctly? Next, the editor will explain to you one by one.

Propagation method of cactus

1. Sowing seeds

Jinji, Jujiu jade, Huang Weng, Huan Fengyu and other growth years are also difficult to breed bulbs for division and reproduction, and can only be sown. Sow the seeds in June, soak the seeds in warm water for 3 days before sowing, and then sow them in broken bricks; sow the seeds at a depth of 2 cm between the seeds. After sowing, the water was fed by basin bottom immersion method, covered with white paper and glass, kept at room temperature of about 25 ℃, and seedlings could emerge one after another after 30 days.

2. Grafting

When grafting, first flatten the top of the rootstock, and then cut part of the stem flesh and bark around the trigonous sword or grass ball at a 30-degree angle downwards. The purpose is that after grafting, the succulent and pulpy stem flesh on the top cutting surface of the rootstock will dry down due to water evaporation, but the leathery bark around it will not shrink, and when the scion sinks as the stem meat of the rootstock shrinks, the hard skin around the rootstock will open the scion and die.

How to sow cactus

1. Sowing time

The suitable sowing time of cactus is from May to June or from September to October, and the best time is 20-30 ℃ at room temperature.

2. Sowing temperature

The room temperature of the cactus should not be lower than 15 ℃ after winter, otherwise the young ball will become frostbitten and rot gradually.

3. Sowing method

Step one: prepare the soil. It can be perlite, vermiculite, fine soil, rice husk charcoal, red jade soil. (all are the smallest size of soil, but it is best not to have powder.) the basin must be new, and so is the soil. Because the old potted soil has bacteria more or less.

Step 2: pour the soil into the small black square and pour the soil to the boundary of the basin, because there is a layer of shop at the back.

Step 3: disinfect the soil, which is also a crucial step. If this step is not done well, the budding rate is terrible.

Step 4: write notes, this, you can remember when broadcast, what is broadcast.

Step 5: when the soil is disinfected, when you see the surface soil getting wet, you can put down the seeds (cactus is not covered with soil when sowing).

Step 6: pack it in a sealed bag. Wait for it to sprout. Normally, the cactus can sprout in 3-4 days.

The way to make the cactus blossom

1, light temperature: cactus requires plenty of sunshine, often put the cactus indoors for a long time, lack of sunshine, it will not blossom. The cactus needs to live in warmer environmental conditions, and it will not blossom if the ambient temperature is less than 20 degrees.

2, watering: cactus like dry living environment, must not water more, do not make the basin soil too wet, but should be dry rather than wet. Especially during the dormant period in winter and summer, watering should be controlled.

3. Fertilization: cactus is resistant to barren and drought, but it is not easy to blossom under the condition of drought and lack of fertilizer. Therefore, proper water and fertilizer should be given in cultivation, and thin and rotten cake fertilizer should be applied every 10 days to half a month in the growing season. Fertilization should not be excessive, and excessive fertilization will also lead to non-flowering.

4. small environment: pay attention to creating a local environment with suitable temperature and high humidity for the cactus, such as making a closed shed with plastic film on the windowsill, in which the cactus is maintained, which not only grows faster, but also has bright colors, but also blossoms easily.

The treatment method of cactus ball

1. Get the ball. When the balls are big enough, you can take them off, break them off with your hands or take them off with a tool. It is a pity to throw away the ball directly. It can be dried in a cool and ventilated place, and then it can be propagated. This is the cuttage of the cactus ball.

2. Cutting. When cutting the small ball, we need to choose the right soil to make it take root. Culture pot can be used to choose a small flowerpot, diameter 4--5cm can be, not too deep, shallow pot can. Place the configured soil in the flowerpot, spray the soil with water, and place the dried balls neatly on the surface of the soil.

3. Take root. During this period of time when the ball takes root, in order to do a good job in daily management, watering is needed when the potted soil is dry, but not too much, because the flowerpot is too shallow, so it is best not to accumulate water. Generally speaking, the small ball will take root in about half a month, and the root is relatively strong.

The above is a general introduction to the breeding methods of cactus, hoping to help small partners in need. The breeding way of cactus is mostly sowing and cutting, the maintenance process is also very easy, like flower friends quickly raise it!
