There are two ways to dry the droplets. One is to drop the drops in the hanging bag, and the other is to dry the pipe. Hang the bag and drop it to dry. Firstly drill the hole on the trunk below the bag with an electric drill (about 3 to 5 centimeters in depth and dip it down). Hang the bag with the nutrient solution on a branch of a certain height from the ground. The dripper is inserted into the hose (diameter is slightly smaller than the hole in the trunk), one end of the hose is placed in the bottom of the bag containing the nutrient solution, and the dripper end is used to suck the infusion solution into the hose and insert the dripper into the hole. , That is to start to drop droplets. The 10 litre bag solution can generally be absorbed within 5 hours. In addition to being directly used for production, this set of equipment is also conducive to scientific experiments and is convenient for exploring different formulas for water and fertilizers.
Pipeline drip dry is developed on the basis of dropper dry, its obvious advantage is that special labor, water and fertilizer medicine to a container, a large area of ​​fruit trees can get a lot of water and fertilizer medicine in a short time. Under the background of the current shortage of rural labor and rising labor costs, this technology has outstanding advantages. The pipeline can be dripped and dried, and can be combined with the hanging bag to drip dry. The formulation of the hanging bag to be dripped and dried can be dripped and drained for large area applications. Pipes drop only one branch per row (and conventional drip irrigation requires two). Each tree requires only one dripper (drip irrigation requires 4 to 6 drippers), so the cost is significantly lower than drip irrigation.
The pipeline drop consists of the following components:
(1) Containers containing water and fertilizers: The containers may be water towers, concrete tanks, etc., and the size may be determined according to the area of ​​the dried droplets. The container is placed at a height of more than 1.5 meters above the ground and forms a pressure difference. The container has inlet holes, outlet holes and drain holes. The cover can be filled with fertilizers, pesticides, etc. The inlet hole is the inlet, the drain hole is the outlet for flushing sediments and debris, and the outlet is connected to the main pipe.
(2) Supervisor: Manufactured using pvc hard pipe, connected to the water outlet of the container, and the switch between the container outlet and the main pipe.
(3) Branch pipe: It is made with Nikko or drip irrigation pipe, and it is inserted into the supervisor to lead to the fruit tree line.
(4) Hose: One end of the hose is inserted into the dripper, and the other end is inserted into the branch tube. When infusion, use an electric drill to drill a hole in the litchi trunk and insert the dripper end into the hole in the trunk.
In the infusion, after the pipe network is connected, the opening of the outlet of the container is opened, and the water and fertilizer solution enters the tree body under the pressure of the difference in position.
Acne Patch3
The main material of salicylic acne patch is hydrocolloid, which is composed of hydroxymethyl cellulose, medical hot melt adhesive. patch acne is used to apply to the surface of acne, absorbing tissue secretions in a physical way and creating a moisture-balanced environment around the acne. Korean acne patches has a flat back and neat edges, with no defects of decoupling. Acne scar patch can absorb more than twice of its own tissue fluid. Acne cover patch is disposable. Keep skin clean before acne pimple master patch use, do not apply any products, do not use with ointment. Acne patch microneedle is most effectively absorbed when the acne appears pus-filled. To use acne pimple healing patch, remove the sticker, peel off the backing paper, apply it to the wound and gently press around it to fix it. Acne spot patches is most effectively absorbed when the acne appears pus-filled. To use acne removal patch, remove the sticker, peel off the backing paper, apply it to the wound and gently press around it to fix it. After the color of the custom acne patch changes from clear to white, replace the sticker. Salicylic acne patch has good water resistance and can be used during makeup or bathing.
