Tea Plant Cultivation Techniques: How to Apply Topdressing in a Tea Garden Scientifically?
How should topdressing be applied in a tea garden? Please provide an introduction to the method. A tea garden can refer to the following methods for topdressing: 1. Applying it as topdressing. In early spring, during the picking period, using nitro compound fertilizer as topdressing takes effect quickly and shows remarkable results. Compared with urea, urea after broadcast application takes 7~10 days to take effect, has a single nutrient component, and is prone to ammonia volatilization loss to a fairly large extent, with low utilization efficiency and delayed effect, so it cannot achieve the ideal yield-increasing effect; switching to binary nitro compound fertilizer, after broadcast application it can begin to take effect in 3~4 days, has a nutrient composition that is not single (contains "dual nitrogen" plus phosphorus), has small volatilization loss, and has very high utilization efficiency, making it an excellent choice for promoting high yield of spring bud tea. It is recommended that during the spring tea picking period, apply once at an interval of 8~10 days, with a dosage of 15 kg per mu each time; apply 5~7 times in total.
