Tips for growing flowers and fertilizing
During the family flower cultivation process, improper fertilization is the main cause of yellow leaves and rotten roots. Mastering scientific fertilization methods can not only promote the healthy growth of plants, but also extend the flowering period and enhance the ornamental value. This article will systematically analyze the four core elements of fertilization to help you create a green plant kingdom. 1. Seasonal fertilization cycle management 1. Fertilization strategy in spring and summer March to August is the rapid growth period of plants, and it is recommended to apply diluted liquid fertilizer every 15 days. Leaf viewing plants such as rose and green radish can increase the proportion of nitrogen fertilizer and combine foliar spraying potassium dihydrogen phosphate solution. 2. Fertilization adjustments in autumn and winter will gradually reduce the frequency of fertilization to once a month starting from September. Quick-acting fertilizers will be stopped during the dormant period from December to February of the following year, and slow-release fertilizer granules can be buried and applied to maintain basic nutrients. 2. Relationship between temperature and fertilization When the temperature is>30℃ or <15℃, fertilization should be suspended. The optimal fertilization temperature is 18-25℃. It is recommended to operate at 17-19 in the evening in summer and noon in winter. Succulent plants need to pay special attention to the principle of stopping fertilization at low temperatures. 3. Scientific control of fertilization amount 1. Standardize fertilization at young seedling stages. Use 1/4 of the standard concentration in the first three months for newly planted plants, and adopt the principle of "thin fertilizer and frequent application". Add 3-5 drops of nutrient solution to hydroponics plants every time they change water. 2. Fertilizing techniques for adult plants apply phosphorus and potassium fertilizer during the bud stage of flowering plants, diluted at a ratio of 1:1000. If the leaf tips are found to be scorched, immediately irrigate the roots with clear water three times, each time at an interval of 2 hours. 4. Accurately select the type of fertilizer. Universal compound fertilizer (N-P-K=15-15-15) is suitable for daily maintenance. Use high-phosphate fertilizer (10-30-20) before flowering. Organic fertilizer needs to be completely decomposed, and a mixture of sheep manure and garden soil at a ratio of 1:5 has the best effect.
By establishing a four-dimensional management system of season-temperature-dose-fertilizer species, plant stress resistance can be significantly improved. It is recommended to coordinate with soil pH testing (maintain 6.0-7.0) and regularly rotate fertilizer types. Practice has found that plants that adopt the principle of "3 parts of fertilizer and 7 parts of water" have an average increase of 40%.
