Tea garden soil improvement is very important for improving quality

In the practice of tea production, the author found that the reason why Anxi Tieguanyin has a special charm, in addition to the effects of tea varieties and processing techniques, the main reason is also the special minerals and trace elements contained in the soil of the production area, which can be effective. Promote the secondary metabolism of tea trees, synthesize more special tea aromatic substances, and form the so-called Guanyin rhyme. However, after the 1980s, most tea farmers increased the yield of tea by using a large amount of chemical fertilizers, resulting in the predatory intake of soil organic matter, minerals and trace elements. However, the tea garden management failed to replenish in time, resulting in soil nutrient imbalance. Decreased fertility affects the quality of tea. Therefore, the improvement of tea garden soil is very important to improve the quality of tea and maintain the quality of tea. Now we will guide tea farmers to implement soil improvement from the following aspects:

The first is to carry out fertilizer reform. We will vigorously promote the use of farmyard manure based on sheep manure, with little or no chemical fertilizers, and increase soil organic matter.

The second is to promote formula fertilization. According to the analysis of soil nutrient in tea gardens, it is indicated that the tea garden fertilization recommendation card is distributed to help tea farmers to carry out scientific and rational formula fertilization and balance the soil nutrients. The effect is very obvious. At the same time, it is necessary to pay attention to guiding tea farmers to apply microbial organic fertilizers, increase soil microbial flora and activate soil.

The third is to implement tea garden coverage. In view of the problem that the soil surface of the tea garden is bare and the soil is seriously acidified, the tea farmers are guided to use the straw to cover the garden in the management of the tea garden. It can not only neutralize the soil pH, but also preserve the soil and protect the fertilizer, increase the soil organic matter and limit the weed growth. . In addition, the organization guides tea farmers to grow economic crops such as peas and soybeans in the tea garden to increase the organic quality of tea gardens.
