The latest culture methods and matters needing attention of cactus

Cactus is a kind of spherical stem, thorn, flowers have high ornamental value of plants, also known as grass ball, Changsheng pill, short hair pill, etc., for the shape of the spherical cacti family plants collectively, native to the desert zone, hi high temperature and drought climate, stem spherical or elliptical, generally in the morning or evening flowering, flowers born in the longitudinal edge thorn cluster, the following we will take a look at the cactus breeding methods and precautions bar!

The growth habits of cactus

1, moisture: cactus drought resistance, growth season should be properly watered, dormant period to a little dry is appropriate.

2, fertilizer: cactus like fertilizer, growth period can be 10 to 15 days to apply 1 liquid fertilizer, dormant period that is to stop.

3. Soil: Cactus should grow in fertile, well-ventilated and calcareous sandy loam.

4, temperature: cactus love warm, too high temperature will make it forced to "sleep." It can also withstand low temperatures of about 0℃.

5, light: cactus like sunshine, summer to appropriate shade, but excessive shade will lead to its failure to bloom.

The breeding method of cactus

1, ball: in April to September, cut from the mother plant to dry for 2 to 3 days, or dip in the cut plant ash, and then insert into the basin or wet sand table, can not be watered, a little spray water can be. Do not break the ball by hand. It is best to cut it from the base of the ball with a knife or scissors to prevent pulling out the pith. Many seed balls have taken root on the mother plant, and after cutting, they are placed in indoor maintenance at about 20℃. If they are outdoors, they should be properly shaded, and new scenes can be formed after 1 month.

2. Grafting: In May to July, when it grows vigorously, use grass balls, triangular pillars, cylinders and rattan cacti as rootstocks. The thickness of rootstocks should be greater than that of scions. First, use a knife to cut the top of the rootstock, then cut the lower part of the scion, then align the seed ball center with the central pith of the rootstock, make it closely adhere, then bind and fix it together with the flowerpot with a rope, and then put it in indoor ventilation or outdoor shade for maintenance.

3, sowing: cactus self-pollination ability is poor, to carry out artificial pollination to bear fruit. Seed life 1~2 years, need to germinate at high temperature, so should be in June ~ July sowing. Soak seeds in warm water for 2~3 days before sowing. The basin soil or sand bed should be mainly loose loam. The sowing depth should not be seen. The seed spacing should be 2~3 cm. Water with the bottom of the basin swimming method, covered with white paper or glass, so that seedlings fully see the light, do not topdressing.

Culture method of cactus

1. Soil: Cactus potted plants can be prepared by mixing 3 parts of decayed leaf soil, garden soil and coarse sand, respectively, with plant ash and decomposed bone powder. It should be potted in early spring. The bottom of the pot should be padded with a layer of small stones about 3 cm thick to facilitate drainage. The planting depth should be flat with the soil surface.

2, light: cactus like sunny environment, but exposure will slow down the growth rate of cactus, of course, not to be sunburned, if you want cactus to grow faster, it is best to find a cool environment for cactus when the sun is too hot.

3, watering: the vast majority of cactus originated in South and North America hot and arid desert wilderness, root water absorption capacity is very strong, if too much watering will make the roots fester, some large cactus even if not watered for one or two years will not die.

4, temperature: the best growth temperature of cactus is 20~35℃. Most species prefer a larger temperature difference between day and night, which is conducive to the production and accumulation of organic substances under the conditions of less than 35℃ during the day and about 15℃ at night, thus promoting the vigorous growth of plants.

5, fertilization: cactus like fertilizer, fertilizer tolerance, spring pot after 1 month began topdressing, growth season every 20 days or so topdressing decomposed 10 times liquid fertilizer mixed with the same amount of 1000 times potassium dihydrogen phosphate or 1000 times "flower more" general fertilizer 1 time, winter no fertilizer.

6, change pots: cactus change pots should be cut off part of the old roots, dry 4 to 5 days later and then pot planting, planting should not be too deep, to the ball root neck and soil level is appropriate. In order to avoid causing rotten roots, do not water the newly planted cactus, only spray 2~3 times a day.

7, pests: cactus in high temperature, poor ventilation environment is prone to pests, diseases can be sprayed carbendazim or thiophane, pests can be sprayed dimethoate to kill, but no matter what kind of liquid spray should be carried out outdoors.

Notes on cactus

1, cactus in the breeding process should pay attention to its water requirements, light intensity, fertilizer and other factors, once improperly handled is likely to not survive.

2, spring and summer season cactus growth began, every half a month to apply fertilizer, the best nitrogen, phosphorus and potassium fertilizer, in addition to appropriate shade, do not expose to the sun.

3, winter to move potted cactus indoor, room temperature above 5℃ can safely winter, pot soil to be relatively dry, otherwise easy to rot roots.

Cactus is not suitable for pouring too much water, otherwise the roots will rot. It is best to irrigate once every one to two months in spring and summer, and two to three months in autumn and winter.

5, cactus like the sun, not afraid of dry, pay attention to watering must be poured through.

6, cactus for pots should be carried out in the spring, just for pots of cactus can not be watered immediately, should be watered after 1 week.
