1. For topdressing application In the early Spring season, the use of nitro compound fertilizer as top dressing during mining is quick and effective. Compared with urea, urea can take effect after 7~10 days, the nutrient composition is single, and the ammonia volatilization loss is easy to be formed. The utilization rate is not high and the effect is too late, and the ideal yield increase effect is not obtained. Applying the binary nitro compound fertilizer, it can start to take effect after 3~4 days after application, and the nutrients are not only--(including ''double nitrogen' plus phosphorus), the volatilization loss is small, and the utilization rate is high, which is to promote the high yield of spring bud tea. . recommendations spring and a good choice during the extraction, an interval of 8 to 10 days once administered, the amount per acre 15 kg / second; total administered 5-7 times Copyright Linyi fertilizer. 2. Applying lightly pruned in late May. Young tea garden (three years or so) In order to cultivate the tree potential, a high-yield canopy is formed, and the pruning is performed after the end of the spring tea in the end of May. At this time, use the opportunity to facilitate the ditching and fertilization after trimming, along the edge of the tea canopy drip line - 4 to 5 inches wide, 3 inches deep in the fertilization ditch, the use of ternary nitro compound fertilizer 35 ~ 40 kg, vegetable cake After 30 kg of dryness, apply it to the ditch and cover the soil.
