Fertilizing method for improving tea garden soil

Abstract

The invention discloses a fertilizing method for improving tea garden soil. The method comprises the following steps: 1) acidifying and improving soil with pH value below 4.5 in the first ten-day period of October in each year; and 2) applying organic fertilizer in the middle ten-day period of October to the middle ten-day period of November in each year, wherein the organic fertilizer comprises the following components in parts by weight: 100 parts of beans straw fermented substance, 80 parts of corn straw fermented substance, 80 parts of wheat straw fermented substance, 50 parts of paddy stem fermented substance, 4 parts of bacillus subtilis, 4 parts of bacillus licheniformis, 3 parts of actinomycetes, 2 parts of bacillus, 5 parts of photosynthetic bacteria, 3 parts of lactic acid bacteria, 8 parts of selenium fertilizer, 8 parts of zinc fertilizer and 5 parts of rare earth fertilizer; 3) applying topdressing in the last ten-day period of January in each year. According to the fertilizing method for improving tea garden soil provided by the invention, the soil organic matter can be added and updated; the microorganism multiplication can be boosted; the physicochemical property and biological activity of soil can be improved; the soil can continuously keep activity; the contents of selenium, zinc and tea polyphenol in tea leaves can be increased; the yield of the tea leaves can be increased; the fertilizing amount and the fertilizing times can be reduced.

Description

technical field [0001] The invention relates to the technical field of tea tree planting, in particular to a fertilization method for improving tea garden soil. Background technique [0002] Fertilization is one of the important technical contents of supplementing nutrients in tea gardens. The soil is rich in various nutrients, which complement each other to ensure the growth status of tea trees and tea output. Tea tree is a perennial leaf plant. The young shoots and leaves of tea tree are the high-quality tea raw materials picked. In order to ensure the output of tea tree and the quality of tea, the soil needs to have suitable nutrients, so it is necessary to continuously apply fertilizers. to supplement nutrition. [0003] The current standard method of fertilizing tea gardens is to apply fertilizers containing N, P, K and other nutrient elements in furrows according to the soil fertility status and the law of tea tree fertilizer requirements. Specifically, the fertilizat...
