How to raise green radish
As the king of indoor leaf-viewing plants, green radish has become the first choice for home green plants due to its tenacious vitality and air purification ability. However, in order to keep green radish in a bright and green state, scientific maintenance skills are needed. Starting from the two major systems of soil culture and hydroponics, this paper systematically analyzes the complete knowledge framework of green radish conservation. Strategies for cultivating and protecting green radish soil The ideal soil formula is garden soil: humus soil: river sand =3:5:2, and the pH value is controlled between 5.5 and 6.5. The pots need to be changed every spring. Select a breathable pottery pot with a diameter of 5 cm larger than the original pot. When changing the pot, keep 1/3 of the core soil. After pruning 1/3 of the old roots, soak and disinfect them with carbendazim. The golden rule of water and fertilizer management adopts the "see dry, see wet" watering method, which is watered thoroughly once every three days in spring and autumn, and sprayed once in the morning and evening in summer. Apply nitrogen, phosphorus and potassium compound fertilizer diluted 1000 times once a month, and stop fertilization in winter. Use tap water to stand for 48 hours or add 0.5ml/L citric acid to adjust the pH value. The optimal growth temperature band for key parameters of light and temperature control is 18-28℃, and remains above 12℃ in winter. The light intensity is controlled at 5000-8000lux. The east-facing window sill has the best scattered light for 3 hours a day. In strong light environments, a sunshade net can be used to filter 30% of the light. The full-process hydroponic maintenance hydroponic system of green radish is built and selected in transparent glass containers, and the water level inundates 2/3 of the root system. The plants were fixed with ceramsite + medical stone, and the water was kept clear by adding 0.1% activated carbon. Change water every 2 days in the initial stage, and change water once a week after rooting. Nutrient solution formulation management uses Hoagland nutrient solution (diluted to EC value of 1.2mS/cm), and adds 2 drops of nutrient solution to every 500ml of water. 0.01% ferrous sulfate can be added to prevent yellow leaves in summer, and 0.005% potassium dihydrogen phosphate can be used in winter. How to raise green radish Common problems Solutions for yellow leaf diagnosis and treatment of new leaves at the top are yellowing due to iron deficiency, so 0.2% iron chelate solution can be sprayed; the root system needs to be checked for yellowing of old leaves at the bottom. After hydroponics plants prune black roots, soak in 0.1% potassium permanganate solution for 20 minutes. To control pests and diseases, red spiders are sprayed with matrine 1000 times, and hymoxazole is used to irrigate roots for root rot. Regularly wipe the leaves with a damp cloth to keep the air holes on the leaves smooth.
Through scientific soil culture and hydroponic system management, combined with temperature and light regulation and nutrient supply, green radish can achieve green growth throughout the year. It is recommended that novices start with hydroponics and try soil culture modeling after mastering the basics. By regularly observing the status of the plants and adjusting the maintenance plan in time, green radish can become an indoor green lung that always maintains vitality.
