Drip irrigation

To prevent drought damage in tea gardens and reduce losses in tea production, supplementary measures to replenish water and suppress evaporation can be taken before the onset of drought. These include irrigation to supplement water, loosening the soil and weeding, inter-row grass covering, etc., to maintain and regulate soil moisture and improve the microclimate around the tea plants, thereby enhancing the tea trees' drought resistance. Irrigation Replenishment Tea garden irrigation methods include furrow irrigation, sprinkler irrigation, drip irrigation, among others, each with its own advantages and disadvantages. Furrow irrigation is suitable for flat tea gardens and can quickly increase soil moisture levels, promptly rescuing drought-stressed tea trees, but it consumes a large amount of water, has a small impact on air humidity, and can lead to waste of water resources through surface runoff and deep seepage, as well as damaging some of the topsoil structure. Drip irrigation reduces evaporation and saves water, but it requires a higher initial investment and cannot effectively improve the microclimate of the tea garden. Therefore, in recent decades, sprinkler irrigation has been the primary method used for drought prevention and mitigation in tea gardens. Sprinkler Irrigation can not only increase soil moisture but also lower…
