With the drop in temperature, the growth of the above-ground parts of tea trees slows down gradually while that of the underground parts remains relatively active. Applying base fertilizer in autumn can improve the efficiency of fertilizer use by the tea trees and contribute to enhancing the quality and yield of spring tea the following year. Therefore, it is essential to apply base fertilizers scientifically to tea trees in autumn. I. Principles of Fertilization 1. Organic and chemical fertilizers should be used in combination, with organic fertilizers replacing part of the chemical fertilizers, and base fertilizers should be applied deeply; 2. Maintain a suitable nutrient ratio. Based on soil fertility conditions and tea yield, determine the nitrogen fertilizer amount and enhance the combined application of phosphorus, potassium, and magnesium fertilizers, paying attention to the supplementation of sulfur, boron, and other nutrients; 3. For tea gardens with severely acidified soils (soil pH < 4), measures such as applying lime, soil conditioners, or increasing the application of mature livestock manure can be taken to gradually improve the soil; 4. Combine scientific fertilization with green cultivation techniques that increase yield and efficiency. II. Methods of Fertilization 1. Timing of base fertilizer application: It…

Weed control is a critical aspect of managing young tea gardens in Guizhou. Techniques such as manual weeding, tillage weeding, and mulching have proven effective, but they require significant labor and material inputs. Manual weeding alone can cost 700 to 800 RMB per mu, increasing the overall management costs of the tea garden. Intercropping soybeans in young tea gardens can effectively suppress weed growth, improve the ecological environment, and enhance soil fertility. Additionally, this practice generates supplementary income of around 1,000 RMB per mu. Soybeans are an important oilseed crop, and China's current production falls short of domestic demand. Intercropping soybeans in young tea gardens aligns with national policies aimed at increasing soybean production capacity and ensuring food security. To leverage the weed control and soil fertility benefits of intercropping soybeans, the Guizhou Academy of Agricultural Sciences Tea Research Institute has developed this plan. Soybean intercropping in tea gardens in Datun Village, Shiqian County General Requirements 1. Adhere to Tea Garden Safety Principles All pesticides and fertilizers used in tea gardens must comply with Guizhou's safety standards. No pesticides or fertilizers prohibited in tea gardens should be applied, even if they are suitable for soybeans. 2. Balance Tea Management and…

This article constructs a flavor wheel for Pu'er tea and Fu brick tea from the dimensions of aroma and taste, establishing a sensory quantitative descriptive vocabulary list for both teas. The aim is to determine sensory descriptive terms that can be used to describe Pu'er tea and Fu brick tea, providing application value for distinguishing, evaluating their sensory characteristics, and developing products related to these teas. In this study, 35 representative samples of Pu'er tea and 35 of Fu brick tea from different years and origins were selected (Table 1). Referring to the black tea sensory evaluation method in GB/T 23776—2018 "Sensory Evaluation Method for Tea," the aroma and taste of the teas were evaluated. This led to a comprehensive understanding of the sensory flavor characteristics of both types of black tea and the further construction of a flavor wheel. The Pu'er tea flavor wheel, as shown in Figure 1, includes two categories: aroma and taste. The outermost layer contains specific descriptors, totaling 40. Aroma descriptors include aged fragrance, camphor aroma, ginseng-like aroma, herbal medicine aroma, soybean aroma, hay aroma, jujube aroma, lactic acid scent, fresh aroma, floral honey aroma, mushroom aroma, smoky charred scent, and 31 others. Taste descriptors…
