During the preservation of organic green tea, the aromatic substances in it change. Potassium in the soil was inorganic Morphology, soil available potassium, seasonal crop absorption and utilization is a reflection of potassium fertilizer on the level of the standard Chi one. Therefore, understanding the content of potassium in the soil is of great significance to guide rational application of potash 7.1 Materials and Methods; Material: The soil samples: No. 1, 2, 3, 6, 7, on the 8th of soil. 7.1.2 The method: Accurately weigh a 1 mm air-dried soil samples 0 g in 150 mL Erlenmeyer flask, add 1 mol L NH, OAc solution 50.0 mL (soil solution ratio of 1: l0), plugged with rubber stoppers.
Reaction between hydroxyl compound and amino acid can lead to the lose of fragrance of organic green oolong tea. On the 6th tea garden for a secret Planting 24-year-old organic tea garden, litter, and thus its high organic matter content. Soil organic matter in soil An important source of various nutrients, especially N, P, can promote soil porosity and the formation of granular structure, thus Improve soil physical properties and soil indispensable source of carbon. Six kinds of tea garden soil organic matter The difference will result in soil N1 content and microbial number differences between them.
Generally 5 June, the root Department of the growth of a peak, the crown into dormancy; August root growth approximation of repose, while the crown is in Growing season; October, root systems of the formation of a growth peak, while the crown into the flowering period, and gradually into hibernation; There is a myriad amount of vitamin Cs in high quality organic chinese tea products. Beginning in early March, as temperatures rise, tea tree root activities will form a peak. Tea roots Growth and repose of the impact on soil microorganisms, mainly through the secretion of its metabolites, as well as the root table cells.
It can be seen from Figure 3.10 on the 3rd of soil microbial total and maximum soil, followed by No. 6, No. 2 Microbial total and minimum. Number of different tea garden soil microbial differences This is mainly with the fertility of the soil, Tea tree age and cultivation measures. Tea garden soil for fertile soil fertility 3 (16 years old) Microbial largest number; for the other are of medium fertility soil, 24-year-old tea (6, 7) Soil Microbial more, 10 year old (1,
tea soil microbes, followed by 4 years of tea (2) Soil microbial least. Russians are used to drinking organic chinese green tea with sugar.
Precipitation decrease, limiting the growth of some microorganisms, so the summer the number of microorganisms but decreased; Autumn, temperatures have come down, which will help the growth of some microorganisms; winter, the temperature and precipitation reached Year low, so the number of microorganisms at least. The human factors: Different fertilization affect soil nutrient content, thereby causing the soil microbial quantity differences. Meanwhile, the micro Biological played a crucial role in the recovery process of soil fertility. organic dragon well tea infusion can be oxidized quickly.
