In the practice of tea production, the reason why Anxi Tieguanyin has a special flavor, in addition to the role of factors such as tea varieties and processing techniques, the main reason is that the special minerals and trace elements contained in the soil of production areas can effectively promote the tea tree. Secondary metabolism, the synthesis of more special aromatic substances in tea, the formation of the so-called Guanyin rhyme. However, after the 1980s, tea growers mostly used chemical fertilizers to increase tea yields, resulting in predatory ingestion of soil organic matter, minerals, and trace elements. Tea plantations, however, failed to replenish them in time, leading to imbalances in soil nutrients. The decline in fertility affects the quality of tea. Therefore, soil improvement in tea gardens is crucial to improve the quality of tea and maintain the quality advantages of tea. Now we will guide tea farmers to implement soil improvement in the following aspects:
The first is to carry out fertilizer reforms. We will vigorously promote the use of farmyard manure mainly based on sheep manure, apply little or no fertilizer, and increase soil organic matter.
Followed by promotion of formula fertilization. According to the soil nutrient investigation and analysis results in tea gardens, tea plantation fertilization recommendation cards were distributed to assist tea farmers in scientific and rational formula fertilization to balance soil nutrient composition. The effect was obvious. At the same time, attention is also being paid to directing tea farmers to use microbial organic fertilizers to increase soil microbial flora and activate soil.
The third is to implement tea garden coverage. In view of the fact that the tea plantation is exposed and the soil is seriously acidified, the tea plantation management guides tea growers to use straw or mango cheekbones for the purpose of covering the gardens. In particular, the rice straw cover is promoted, which not only neutralizes soil pH, but also protects water, soil and soil. It can also increase soil organic matter and limit weed growth. In addition, the organization led tea growers to grow peas, soybeans and other economical green manures in the tea garden to increase the coverage of the garden.
The fourth is to carry out tea plantations. The mobilization of people to carry out tea garden management and the use of sheep manure, peanut vines and other tea garden management work, so that the tea garden plough the tea farmer to manage the daily affairs of the tea plantation.
