Soil fertility

In recent years, the area of tea gardens has grown annually in response to the increasing demand in the tea market. However, the expansion of tea garden areas has brought about a series of issues including soil erosion, acidification, and reduced fertility, which are detrimental to tea yield and quality. This article, based on the current distribution of tea gardens in our country, summarizes the more common problems in the tea garden soil environment. It also analyzes the remediation effects and mechanisms of applying biochar, microbial fertilizers, and compound conditioners, aiming to provide a theoretical foundation for future soil improvement work in tea gardens and the promotion of soil conditioners.

I. The Area and Distribution Characteristics of Tea Gardens in Our Country As of 2022, the total area of tea gardens in our country has reached 3.3303 million hectares, ranking…

Impacted by a moderate-strength El Niño event, and superimposed on the backdrop of global warming, the global average temperature in 2023 may break the record for the warmest year set in 2016. It is expected that temperatures in most regions of China will be close to or higher than the long-term average this winter through to next spring, but with active cold air phases. Precipitation in southern regions is expected to be above normal, increasing the risk of compound meteorological disasters. Given these complex climate changes, timely management of tea gardens during winter can help them safely overwinter and lay a foundation for high-quality tea production and increased income for tea farmers in the coming year. So how should we manage tea gardens in winter? Follow along as we look at the winter and spring tea garden management technical guidelines developed jointly by the Department of Plant Industry Management of the Ministry of Agriculture and Rural Affairs, the National Agricultural Technology Extension Service Center, and the Expert Advisory Group for Tea of the Ministry of Agriculture and Rural Affairs. 1. Disaster Prevention 1.1 Preventing Frost Damage Monitor weather forecasts closely. Before a cold wave, implement frost protection measures such as…

Good tea thrives with proper nutrition; fertilizers are the material foundation for increasing yield and improving quality in tea production. Fertilization plays a crucial role in the growth of tea plants and the yield and quality of tea leaves. While some nutrients are supplied by the soil itself, its nutrient content is limited and subject to environmental factors, leading to significant losses through leaching and volatilization, which greatly reduces nutrient availability. This is insufficient to meet the needs of tea plant growth, let alone high yields and quality standards. Additionally, as a leaf-harvesting crop, the annual harvest of large quantities of buds and leaves removes a certain amount of nutrients. Therefore, most nutrients must be replenished through fertilization. When soil nutrient imbalances occur or there is an extreme deficiency of one or more nutrients, it is necessary to use appropriate fertilizers to correct the nutritional deficiencies to ensure high-yield and high-quality tea production. Therefore, proper management of tea gardens during different seasons is crucial, and fertilization is a key technology in garden management that should receive significant attention. Especially during autumn, a critical period for tea garden management, the focus is on rapidly restoring tree vigor to lay the groundwork…
