Instructions: 1. Place the water bag around the bottom of the trunk, tighten the zipper, and place the water pipe at the top of the water inlet to start watering 2. When about 1/4 of the water is poured, slightly lift the two black webbing above the bag body, so that the water can be filled more fully (nutrient solution, fertilizer, medicine, etc. can be added reasonably according to demand) 3. After filling with water, the water in the bag will slowly penetrate and empty within 3-8 hours 4. When not in use for a long time, the water bag can be cleaned, folded neatly, and stored for next use. 5. One or two water bags can be spliced​​together for use Water bag advantages: Water saving - drip irrigation is a local irrigation method for tree roots. It can accurately irrigate and deliver water according to the needs of crops, which is very water-saving. More than 30% water saving than ground flood irrigation Strong adaptability - drip irrigation has low drip intensity, which can adapt to sticky soil with low infiltration, and due to long irrigation time and frequent watering, even in sandy soil with high water permeability, it will not cause serious deep leakage Increase yield - maintain stable soil moisture to improve tree survival rate, drip irrigation can provide timely and appropriate water supply and fertilization to tree roots without causing soil compaction, providing good water and nutrients for tree production Labor saving - drip irrigation is convenient for automatic control, saving labor, and can also be used for fertilization and pesticide application, which saves fertilizer and medicine, and saves labor, which is very convenient
