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.

"Two sprays": A spray of ammonium molybdate. Molybdenum is an important element in maintaining the normal activities of rhizobia in legumes. Foliar sprayed with ammonium molybdate is generally better at the initial flowering and full flowering stages with twice 0.03% to 0.05% solution (about 75 kg per mu). If you can mix potassium dihydrogen phosphate at the same time, the effect is better. Second spray "increase production spirit." According to the survey: After soybeans are sprayed with “promoting yieldâ€, plant height, branching, and pods can be significantly increased, and the yield can be increased by more than 10%. Spraying “increase production spirit†can generally use 10x10 ~ 6 ~ 15x10 ~ 6 concentration of aqueous solution at full bloom, generally about 3 grams per mu.
Soybean "a dozen two sprays" is good
"A dozen": that is, playing the tip. Practical experience, when the soybeans are about to enter the flowering stage before the tip, can make the soybean plants dwarf, enhanced resistance. However, the specific operation must be mastered: "Don't fight late, do not hit fat, thin, do not hit close" principle. At the same time, attention should be paid to not playing too much. Generally speaking, it is advisable to remove the tender tip of 2 to 3 cm at the tip of the main stem.
