The cactus not only has ornamental value, but also absorbs electromagnetic effects. Placing this kind of plant beside the appliances in the home or office can effectively reduce the electromagnetic radiation generated by various electrical and electronic products and make negative particles in the indoor air. The increase in concentration helps the human body to minimize the radiation of various types of electrical appliances. The grafting of cactus on cactus not only makes it beautiful in appearance, but also resembles a rockery tree, and can be seen in the summer beauty of the cactus flower, and can also watch the beauty of the fiery crab claw orchid in the cold winter. Our home is more comfortable and healthy.
First, grafting technology. The cactus used for grafting must be flesh-thick and grow strong. Its cultivation method is modeled on the method of cultivation of common cactus. Generally, the diameter of the pot is selected to be 30 centimeters, and when the cactus grows to a height of 30 centimeters, it is grafted. The scion used in the scion requires the selection of a robust mother plant of C. hirsutum, from which the top branch of the year with tender and nodding is selected as the scion, and the length is 3-4 cm. Cut the wedge on both sides of the lower part of the scion with an alcohol-sterilized blade. The cut length is 0.8-1.2 cm. Grafting time is generally selected in May or in October, and the weather is too cold and too hot for its survival. When grafting, use a thin bamboo stick that is the same width as the scion, and insert a 1.5-2 cm deep slot vertically downwards from the cactus measuring edge along the flat direction as the interface, and then quickly insert the scion into the root block interface. Try to plug in as deeply as possible so that it fits snugly, and then use thorns to fix it. Generally, three scions should be connected to each plant, and after they are well-connected, they should be placed in a cool and sheltered place to keep the potted soil wet for about 20 days. If the scion does not fight, it can survive. After grafting to survive, usually after about a year of growth, the crab claws will surround the cactus. At this time, it is necessary to make a bracket so that the cactus is hung like a fountain on the cactus. The top of the cactus will bloom beautiful flowers in the summer season.
Second, conservation technology
1, watering and water spray. When watering, grasp this principle: "dry thoroughly, do not do dry;" Water temperature should be as close as possible to the soil temperature, summer watering as far as possible in the morning or evening, winter watering from 10 am to 11 o'clock; And put the water directly on the pot, otherwise it will affect the appearance of the thorn.
2, fertilization. Fertilization master the principle: timely, appropriate, and look at the object. Fertilization is conducted in spring and autumn. Fertilization should be conducted once every 15 days. It should be done in the early morning or early evening in sunny days. Fertilizing method is to dissolve the fertilizer to be applied in the water and pour it into the pot in the morning. Better. The concentration is controlled at about 0.2%.
3, light. It is better to have more sunshine, especially the full sun in the winter, more summer and more half-yin conditions, in the summer hot season to be placed indoors. Winter is placed in a sunny room, and can be opened during the Spring Festival.
4, temperature. The suitable temperature is 20-35°C. It is advisable to maintain 10-18°C or more in winter. When the temperature is too high in the summer, you must shade and spray more water on the floor to reduce the temperature.
5. Pest control. Common pests and diseases are: (1) rot disease. Its pathogens are bacteria and fungi. The occurrence of this disease is often related to improper watering, poor basin drainage, and persistent excessive humidity. After the diseased plant was found, the diseased tissue was immediately resected with a sharp knife and the incision was placed in the plant ash. While controlling the watering or changing the basin, it was better to improve the ventilation and avoid excessive humidity during the grafting. (2) Insects and other animal hazards. There are mainly red spiders and cockroaches. For the control of mice and tide insects, 2000 times liquid spraying of flowerbeds and flowerpots can be used. Prevention of snails and clams can be sprayed with lime powder around the flower pots, or can be used with 8% clomazone granules; control of cockroaches and ants You can place drugs for killing cockroaches and ants or sugar water to mix poison with trichlorfon.
