What fertilizer is needed to fertilize green radish
As a star variety of indoor green plants, green radish is deeply loved for its lush green leaves. But many people encounter fertilization problems during the maintenance process-what kind of fertilizer should they choose? How to remedy it when leaf yellowing occurs? This article will analyze the golden rule of green radish fertilization from a professional perspective. Green radish fertilization techniques and fertilizer selection 1. Analysis of basic nutrient requirements Nitrogen element is the core driving force of green radish growth, accounting for 60%-70% of fertilizer formula. It is recommended to use special fertilizer for foliage plants with high nitrogen content, and about 15% potassium element can enhance disease resistance. Commercially available urea (containing 46% nitrogen) and potassium sulfate (containing 50% potassium) are mixed in a ratio of 3:1, which can effectively promote vein development. 2. Fertilization frequency and techniques Water-soluble fertilizers are applied every 15 days during the growing period (March to October), and once a month in winter. It is recommended to use the "sandwich fertilization method": after loosening the soil surface, first spread 1 cm of humus soil, sprinkle with 5-8 grains of slow-release fertilizer, and then cover with thin soil. After the foliar fertilizer is diluted 2000 times, the effect is better when spraying it twice a month. Diagnosis and nutritional remediation of leaf yellowing problems 1. The yellow leaf type judges that the chlorosis of new leaves is mainly due to iron deficiency, and iron EDTA chelate can be applied; the chlorosis of old leaves is often due to nitrogen deficiency, and urea should be supplemented. If the leaf margins are accompanied by scorch and withered, potassium is insufficient, and additional plant ash extract needs to be applied. Overall yellow leaves may be unbalanced due to pH value, so it is recommended to use pH paper to test the soil pH value. 2. Organic fertilizer preparation guide rice washing water needs to add orange peel fermentation for 30 days, diluted by 1:50 use. Beer fertilizer needs to stand for 48 hours to volatilize alcohol, and the ratio of beer fertilizer to water is 1:30. The potash fertilizer prepared by cutting banana peel and soaking for 7 days has remarkable effect on restoring leaf color and luster. Advanced maintenance precautions 1. Fertilization Taboo List Undecomposed poultry manure can easily burn roots, and chemical fertilizer concentrations exceeding 0.3% will cause salt damage. Fertilization should be suspended at noon in summer and low temperature periods in winter, and newly replaced plants should be delayed for 20 days before fertilizing. 2. Supporting maintenance points Keep scattered light for 4 hours after fertilization, and combine it with 85% air humidity to improve fertilizer efficiency. It is recommended to wash the basin soil with clean water every six months to prevent salt accumulation. Rotating the flowerpot regularly ensures uniform light reception, which can increase leaf hypertrophy by 40%.
Mastering scientific fertilization methods and correctly diagnosing the cause of leaf yellowing can restore vitality to green radish. It is recommended to establish a fertilization log to record the time, type and plant response of each fertilization, and gradually form a personalized maintenance plan. When the leaves return to oily texture and the spacing between leaves remains 2- 3 cm, it shows that the fertilization strategy has achieved results.
