The effective use of rice to create "a crop of flowers, all relying on fertilizers" has become a common practice today. Fertilizers have played a crucial role in boosting agricultural productivity in recent years. However, farmers still face challenges when it comes to proper fertilization—such as applying too little nitrogen and phosphorus, overusing chemical fertilizers, neglecting organic options, or failing to tailor their approach to local conditions. These issues often lead to wasted resources and underperforming crops, which hinder overall productivity. By integrating microbial fertilizers, such as bacterial-based products, farmers can enhance yields, improve soil health, and achieve better economic returns.
General Fertilization Methods:
(1) The "pre-promotion" method involves applying most of the fertilizer early in the rice growth cycle. This typically includes heavy base fertilizer and early flooding. Usually, 70-80% of the total fertilizer is applied at this stage, with the remaining used after the rice turns green.
(2) The "pre-promotion, mid-control, post-supplementation" method focuses on early application, emphasizes nitrogen supply during the middle phase, and ensures sufficient nutrients in the late stages. In this method, base manure accounts for 80-90% of the total fertilizer, while ear and grain fertilizers make up 10-20%. It’s ideal for longer-growing varieties like hybrid rice.
(3) The "pre-stable, mid-push, post-protection" method reduces early nitrogen use, applies heavier panicle fertilizer during the middle stage, and uses moderate granular fertilizer later. Here, basic and barley fertilizers account for 50-60%, while spike and granule fertilizers make up the remaining 40-50%.
Kappa Fertilization Method:
(1) Seed dressing:
- For live fields, mix 0.5-1 kg of microbial fertilizer per kilogram of rice seeds, let them germinate, and spread them in the field after 4 PM.
- For seedlings, soak the original base fertilizer, weaning fertilizer, and undisturbed fat with 0.3 kg of microbial fertilizer per 2 minutes of germination.
(2) Base application: Mix fine soil before transplanting and apply it to the field. If using organic fertilizer, combine it with microbial fertilizer and let it sit for 3-4 days. Apply the mixture to the field before planting. Use 2-3 kg of microbial fertilizer per mu.
(3) Foliar spraying: During the middle and late growth stages, this method helps reduce fertilizer usage and recover from damage. Spray 0.3 kg of diluted fertilizer per mu. For more details, visit the official website or consult an expert.
By adopting these advanced fertilization techniques, farmers can optimize resource use, improve crop quality, and achieve sustainable agricultural growth.
