The green radish is wilting. What's going on?
Green radish is an evergreen tree in the indoor leaf-viewing plant world, and its sprawling green leaves can always create a vibrant home atmosphere. However, many flower lovers have found that carefully maintained green radish suddenly appears in an abnormal state of wilting and drooping leaves, which often hides the maintenance misunderstandings of the two different cultivation methods of soil culture and hydroponics. This paper will deeply analyze the causes of leaf wilting and corresponding treatment plans from the perspective of scientific maintenance. The three core causes of wilting of green radish in soil culture are unbalanced in water management. When hardened cracks appear in the surface soil, it indicates that the plant has entered a state of severe water shortage. It is recommended to use the "dipping basin restoration method": immerse the entire flower pot in the water basin, remove it and drain it after the soil is completely moist. This method can avoid water accumulation and root rot caused by surface watering. It is advisable to maintain soil moisture at 40%-60% in summer and control it at 30% in winter. Sudden changes in temperature damage As a tropical plant, when the environmental temperature is below 12℃, the flow of cell protoplasm slows down and the leaves appear dehydrated wilting. In northern winter, plants should be transferred to a position more than 1 meter away from the radiator to avoid secondary damage caused by thermal radiation. Impaired nutrient supply for a long time without fertilization will lead to thin and light-colored leaves. It is recommended to apply special liquid fertilizer diluted 2000 times every month. It is worth noting that the ratio of nitrogen, phosphorus and potassium should be controlled at 3:1:2. Excessive nitrogen fertilizer will cause excessive wilting. Water purification and treatment of hydroponics green radish wilting system solution Water purification and treatment The hydroponics system needs to replace tap water that has been dried for 2 days every week, and the temperature difference between the water temperature and the original culture solution should be ≤3 ° C. When brown mucus is found in the roots, it should be immediately soaked in 0.1% potassium permanganate solution for 15 minutes for disinfection. Light intensity control Hydroponics plants need to receive scattered light of 3,000 - 5,000 lux for 4-6 hours every day, and gauze curtains with a shading rate of 40% can be used for light regulation. The LED plant fill light should maintain an irradiation distance of more than 30cm to avoid light burns. Root health management regularly checks the proportion of white fibrous roots. When browned root systems exceed 1/3 of the total, pruning is needed to promote new growth. Hydroponics bottles should be wiped with vinegar every quarter to remove algae biofilms and maintain light transmittance of more than 80%.
Whether it is soil culture or hydroponics, leaf wilting is a warning sign for survival from plants. By establishing a three-step maintenance mechanism of "observation-diagnosis-intervention" and combining quantitative management with tools such as thermohygrometer and EC value detection pen, green radish can be restored to its green vitality. It is recommended to take a comparative map of plant growth every quarter and establish exclusive maintenance files.
