illuminate
The most important thing in the management of Hu Jin aquaculture is the management of light. Don't put it indoors in a dark place for a long time, but put it on the south windowsill or balcony. In summer, the strong sunlight will burn the stem of Hu Jinqiu, so it needs a little shade. In winter, it should be maintained in a place where indoor light can be direct or there is bright scattered light. Temperature-The optimum temperature for growth is 20 ~ 25 degrees, and the temperature should not be lower than 8 degrees in winter, otherwise spots will appear on the surface of the sphere, especially in early spring and rot in severe cases.
water
Hu Jin is a drought-tolerant plant, but if it is too dry, it will grow slowly. In the process of Hu Jin aquaculture, we should adhere to the principle of "not watering, but watering thoroughly". When sleeping in winter, you should control water and water as little as possible. In case of drought in summer, water frequently, preferably in the early morning and evening, to avoid pouring too cold water at hot noon, which is easy to "catch cold" and cause diseases. If the soil in the basin is too dry at noon, you can spray less water to make the basin surface wet, and you can't spray water on the top of the ball and grafting parts to avoid water rot.
Fertilize soil or land
Appropriate application of cake fertilizer, bone meal or decomposed dilute solution every 15 days in spring and autumn, paying attention to light but not thick. If urea, potassium dihydrogen phosphate and other quick-acting fertilizers are topdressing, special attention should be paid not to let the fertilizers stick to the ball. Spray with clear water after each fertilization to prevent fertilizer from damaging the ball. Fertilization should be stopped in winter and summer, and so should Jinhu, which has just been planted with rice seedlings.
type
1. Sowing method: The seeds harvested in that year have a high emergence rate. Sowing in May-September, 30-40 days after germination, the seedling ball is the size of rice grain or mung bean, which can be transplanted or grafted on rootstock to promote growth.
2. Bulb grafting method: Graft the seedlings cultivated for more than 3 months on the tender ruler to accelerate the growth. When the scion grows to a certain size or the rootstock can't support it, it can be cut, dried and potted by cutting. In an environment with fertile soil and good air circulation, the seedlings without grafting grow rapidly. Potted seedlings or grafted bulbs should be placed in a semi-shady place to avoid direct sunlight. After 7 ~ 10 days, the bulb will not shrink, that is, it will survive.
Matters needing attention in cactus cultivation in Jinhu
Summer is the peak season for the growth of Jinhu Lake, and the water demand increases. In case of drought, water frequently, preferably in the early morning and evening, to avoid watering too cold water in the hot noon, which is easy to "catch cold" and cause illness. If the soil in the basin is too dry at noon, you can spray less water to make the basin surface wet, and you can't spray water on the top of the ball and grafting parts to avoid water rot. Apply 1 ~ 2 times of dilute fertilizer solution containing nitrogen, phosphorus, potassium and other components about half a month during the growth period, and then clean and water it. Organic fertilizer should be fully decomposed and the concentration should be appropriate.
Jinhu likes sunshine, but it needs shade in summer. When the temperature reaches above 35℃, it should be shaded around noon to avoid strong sunlight burning the sphere. /kloc-0 before morning or after 5 pm, it can be placed in the sun to promote more buds, avoid excessive shading, make the ball longer and reduce the ornamental value. The overwintering temperature is maintained at 8 ~ 10℃, and the basin soil is kept dry.
Jinhu Lake has strong resistance to diseases, but in summer, due to humidity, heat, poor ventilation and other factors, diseases and insect pests such as red spider, scale insect and whitefly are prone to occur, so prevention and control should be strengthened. We should strengthen the prevention and control of diseases and insect pests such as red spider, scale insect and whitefly. Spraying 40% dimethoate or 90% trichlorfon 1000 ~ 1500 times to control red spider. When scale insects and whiteflies are found to be harmful, they can be eliminated manually.
The role of cactus Hu Jin
1. Appreciation: Hu Jin cactus is a common plant decoration. Because of its petite and lovely appearance, many people like to use it as an ornament, especially the younger generation. Putting a pot on the balcony or office is both beautiful and beneficial to physical and mental health.
2. Radiation protection: Green plants will carry out photosynthesis in the sun, and Hu Jin cactus is no exception. It can release a lot of oxygen while absorbing carbon dioxide, which will increase the concentration of negative ions and oxygen in indoor air. Hu Jin cactus also has the function of absorbing electromagnetic radiation. Placing this plant next to electrical appliances at home or office can effectively reduce the electromagnetic radiation pollution caused by various electrical and electronic products and reduce the harm of radiation to the body.
3. Dust adsorption: Don't underestimate Hu Jin cactus, because people are still experts in dust adsorption. It can absorb the suspended dust of PM 2.5 in the air and purify the air. Therefore, Hu Jin cactus is the best choice for home and office decoration.
