Fertilizing method of tea garden

Abstract

The invention discloses a fertilizing method of a tea garden. The fertilizing method comprises the following steps: (1) applying tealeaves formula fertilizer in a period from the middle of October to the middle of November every year, wherein the tealeaves formula fertilizer is prepared from of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, selenium fertilizer, zinc fertilizer and rare-earth fertilizer, and the contents of each element in the tealeaves formula fertilizer are as follows: 18 percent of nitrogen, 8 percent of phosphorus, 12 percent of potassium, 1 percent of selenium, 1 percent of zinc, and 1 percent of rare earth; and (2) applying top-dressing in the middle of January every year. According to the fertilizing method of the tea garden, the applied base fertilizer is prepared from of nitrogen fertilizer, phosphorus fertilizer, potassium fertilizer, selenium fertilizer, zinc fertilizer and rare earth fertilizer, various components in the base fertilizer are scientific and reasonable in ratio and are collectively functioned to ensure the high quality and high yield of tea trees; and the fertilizing method can improve the content of selenium, zinc and tea polyphenol; and meanwhile, the growth requirement of the tea trees can be met only by applying the top-dressing for one time every year, the fertilizing times is greatly reduced, and the fertilizing amount can be reduced by 25 percent or more.
