Can orchids be fertilized with bean cakes?
During the maintenance process of orchids, the selection and application of organic fertilizers directly affect the growth status of plants. As a traditional high-quality organic fertilizer, its scientific use method is worthy of in-depth exploration by orchid farmers. Nutritional advantages of soybean cake fertilizer on orchids The growth of organic fertilizers helps soybean cake fertilizer is rich in nitrogen, phosphorus, potassium and trace elements, and its nutrient release rate is highly consistent with the growth cycle of orchids. Application after spring flowering can quickly replenish nutrients consumed by flowering, promote new bud germination and root development, and is more conducive to the balance of soil microbial communities than chemical fertilizers. The golden period of seasonal application is April to June. The best period for applying soybean cake fertilizer. At this time, orchids enter the vegetative growth period. Combined with the temperature and humidity conditions in late spring and early summer, the fertilizer utilization rate can reach more than 85%. It should be noted that application should be suspended during high temperatures above 30℃. The orchid cake fertilizer is correctly applied to the four-step deep fermentation process. After crushing the bean cakes, add water to moisten them in a ratio of 1:3, and put them into a sealed container and placed in an environment of 25-35℃ for fermentation for 45 days. The standard for high-quality fermentation is dark brown, no odor, and loose texture. This process can decompose macromolecular substances to avoid burning roots. The concentration is accurately controlled and the fermentation stock solution needs to be diluted 50 times for use. The unfermented cake fertilizer should be soaked in water at a ratio of 1:15 for 24 hours, and then the clarified solution should be diluted twice. It is recommended that first-time users use the "halving concentration test method" and observe for 7 days that there is no abnormality before applying normally. When the three-dimensional fertilization technique adopts the surface layer spreading method, use 5 g of crushed cake fertilizer per 10cm pot diameter as the benchmark and distribute it evenly along the pot edge. When coordinating root irrigation and fertilization, false bulb areas should be avoided and applied no more than twice a month. It is recommended to use a bamboo stick test method to monitor substrate humidity. Key points for orchid fertilizer efficiency management need to strengthen ventilation management after application and maintain a 60% shading rate for 3-5 days. Stop fertilizer immediately and rinse the substrate with clear water if you find the leaf tips to be scorched. It is recommended to establish a fertilization log to record the application date, concentration and plant response.
Mastering the scientific use method of soybean cake fertilizer can not only give full play to the slow-release advantages of organic fertilizers, but also avoid the risk of fertilizer damage. It is recommended that Lanyou formulate a personalized fertilization plan based on the actual condition of the plants to give new vitality to traditional fertilizers.
