The fruit tree siphon infusion method is a new technique that we have successfully tested in recent years. This technology uses a simple device to directly input nutrient solution into the xylem of the tree body, which can achieve the purpose of integration of water, fertilizer and medicine, increase the utilization rate of fertilizer and water, make 100% of nutrient solution to be used after absorption, and save water resources. The purpose of drought relief. The specific method is shown in the figure.
The main equipment is a hand-held rechargeable electric drill, a siphon tube and a container. The container can be a mineral water bottle, a plastic bag, or a barrel or can. One end of the siphon tube 3 is above the container 2 and the other end of the siphon tube is a free end. When the trees need to be infused, hang the container filled with the required liquid on a branch with a certain height from the ground; use the suction ball to suck the liquid into one end of the siphon tube and stuff the other end of the siphon into the trunk of the tree beforehand. The diameter of the siphon is slightly smaller than the diameter of the siphon, deep in the hole 2-4 cm, you can start the infusion. The siphon tube can have an outer diameter of 6 mm. Note that the location of the hole is generally above the trunk.
Things to note when siphoning fruit trees:
1. The input fertilizer and medicine must be completely dissolved. Because the input solution is transported through the xylem vessels, if there is a sediment in the solution, it will block the catheter and affect the absorption.
2. Infusion of fruit during the sunny days when fruit trees need more water. In doing so, on the one hand, the needs of fruit trees are met, and on the other hand, it is beneficial to the absorption of water and fertilizers.
The absorption rate of siphon infusion varies greatly among different fruit trees. Generally, deciduous fruit trees absorb faster than evergreen fruit trees. It takes only a few hours for the 500 ml solution to absorb quickly and for more than 24 hours for the slow absorption. Changing the pores can promote absorption.
4 drugs must be pollution-free pesticides, fertilizers require all water soluble. Fertilizer concentration can be referenced to the foliar spray concentration.
5. Enter the time. It is advisable to lose the fruit every 20 days in the growing season.
