生物質(zhì)炭對(duì)茶園土壤改良及茶葉品質(zhì)的影響
[Abstract]:In recent years, the excessive application of chemical fertilizer in tea plantation resulted in a series of problems, such as the aggravation of soil acidification and the decrease of organic matter content in tea plantation, which further affected the yield and quality of tea. Biomass carbon is generally alkaline, has high carbon content, large specific surface area, high biochemical stability and strong adsorption properties, can increase soil carbon storage, improve soil pH value and nutrient availability, for tea plantation soil carbon sequestration, Soil improvement and control the loss of soil nitrogen and phosphorus, improve the quality of agricultural products and other aspects have a great effect. In view of the main problems existing in tea plantation soil in China, the characteristics of biomass carbon and the action mechanism of biomass carbon in improving soil were studied, and the improvement of acidified soil with biomass carbon in tea garden and the control of nitrogen leaching resistance in soil were discussed in detail. The effects of soil carbon sequestration and carbon sequestration, as well as the action mechanism of biomass carbon in improving tea yield and tea quality. Based on the above research, the theoretical research direction of biomass charcoal in tea plantation management is prospected, which provides scientific basis for the application and popularization of biomass carbon in agricultural production.
