What kind of slow-release fertilizer works well?

In order to increase the popularization and application of new fertilizers such as slow (controlled) release fertilizers, Zhong Yanhong Sifang began to carry out strategic cooperation with the National Agricultural Technology Promotion Center from 20 15, and arranged 3 1 slow (controlled) release fertilizer experiments in 7 provinces (regions) across the country, covering corn, rice, wheat, sugarcane, bananas and so on. The results showed that, compared with conventional fertilization, slow (controlled) release fertilizers increased the yield of corn by 0.8%-2 1. 1%, rice by 1.5%-33.2%, and potatoes, apples and bananas by 8.7%, 9.9% and 8.5% respectively. Slow (controlled) release fertilizer can reduce unit area consumption and pure nutrient input by 5%-10%; Corn, potatoes and other crops are free of topdressing, while rice, wheat, bananas and apples reduce the amount and frequency of topdressing, saving labor and time, saving costs and increasing efficiency.
