The depth of overwintering of soil pests in the ploughing garden is generally 10-15 cm, and the whole garden is plowed before the beginning of the freezing season or in early spring to destroy the insects and hibernate, so that the earthworms and adults are exposed to the ground and frozen to death, or the birds can feed. At the same time, the garden soil is loosened, which is conducive to soil maturation and water accumulation.
Cut off the diseased shoots on the branches and branches of fruit trees. There are a lot of pests and pathogens that must be completely cut off and burned in winter to reduce the number of overwintering diseases and insects.
The orchard cleans up the winter to conduct a thorough and thorough cleanup of the orchard, and burns or removes litter, weeds, and decay and fruit drop to remove the pests and many pathogenic bacteria. It reduces the number of diseases and insect pests overwintering. .
Blocking the caves The trunks of old and young fruit trees and the branches of the main branches often have some semi-dry caves, making it easy for pests to concentrate their wintering. At the same time as scraping the skin, the steel wire is inserted into the cave to stir and stir to hide the hidden pests, or to inject pesticides. Then the mud is sealed tightly and muddy to block the insects.

ETR has independently developed an integrated vacuum pump unit composed of a water-ring vacuum pump, a gas-water separator, a vacuum solenoid valve, pipe fittings and an electrical control system.
It is a simple, safe and reliable device that continuously serves the wards all day long, without occupying the ward space. The negative pressure is sourced from the vacuum pump unit.
