What is used for foliar fertilization of green radish
As the popular king of indoor green plants, the maintenance of green radish always confuses novice flower friends-obviously watering on time, but the leaves are getting dimmer and dimmer? You may be ignoring foliar nutritional supplements! Foliar fertilization can quickly replenish nutrients, but wrong operation will block pores. This article will comprehensively analyze the correct way of foliar fertilization from fertilizer selection to practical operation techniques. Scientific ratio method for green radish foliar fertilizer The multi-element formula based on urea is recommended to use a gold ratio of 1g urea +1g potassium dihydrogen phosphate to 1000ml of water to form a balanced solution of nitrogen, phosphorus and potassium after dissolution. Experimental data shows that at this concentration, the absorption rate of green radish reaches 78%, which not only avoids fertilizer damage but also ensures nutrient penetration efficiency. The trace element enrichment plan can add 0.5ml/liter of iron chelate every quarter, and combined with magnesium can significantly improve the phenomenon of vein yellowing. Note that calcium needs to be supplemented separately to avoid precipitation with phosphate. Precise application skills of green radish foliar fertilizer three-dimensional spraying method The spraying can is at a 45° angle from 20cm to the leaves, focusing on spraying the stomat-dense areas on the back of the leaves. The coverage rate on both sides should reach more than 85%, but water accumulation in leaf axils should be avoided. The best time is before 10 a.m., when the stratum corneum penetration is best. The dynamic maintenance cycle is once every 10 days in the spring and autumn growing season, the high temperature period in summer is extended to 15 days, and fertilization is stopped during the winter dormant period. Combined with clean water spraying once a month, salt deposition can be effectively prevented. Guide for purchasing green radish foliar fertilizer Four look at the identification method Look at the BA number: Identify the agricultural fertilizer registration certificate; Look at the solubility: the qualified product is completely dissolved in 30 seconds; Look at the pH value: 5.5-6.5 is the most suitable for green radish to absorb; Look at the ingredient list: Reject products containing growth hormones such as naphthylacetic acid. New biological agents recommend seaweed essence foliar fertilizers that are rich in natural auxins, and humic acids can enhance stress resistance. It is recommended to use it alternately with traditional chemical fertilizers. The effect is better if the biological fertilizer + the chemical fertilizer twice a month.
After mastering the correct foliar fertilization method, the thickness rate of green radish leaves reaches 40%, and the gloss is increased by 2 levels. Remember the principle of "applying thin fertilizer frequently" and combining with environmental humidity control, your green radish will show a waterfall growth! Regular cleaning of leaf pores with wet cotton swabs can increase nutrient absorption efficiency by another 30%.
