Look at the tree to see how old the peach tree is, how strong it grows, and how much it produces. The method of combining root application and foliar spray is generally adopted. For mature trees, 0.4 to 0.6 kg of compound fertilizer is applied at each time according to the fertilization period, so as to facilitate continued nutrition supplementation. Such as top dressing after flowering, the main application of nitrogen-based quick-acting roots, and supplemented with foliar spray boron; such as dressing before fruit topdressing, quick-acting potassium-based root application; such as taking fertilizer, can be harvested in September to October , to supplement nitrogen fertilizer, coupled with phosphate fertilizer.
Look at the structure and fertility of the soil to determine the type, quantity, and method of top dressing. Such as sandy soil, low organic matter content, poor structural performance, leakage of water leakage fertilizer is serious, peach trees growing in this soil, each plant quality circle fertilizer 60 kg, plus 0.4 ~ 0.6 kg of fertilizer.
Look at the output to see the amount of fertilizer. The results of a large amount of trees, there must be enough fertilizer, and a reasonable mix of nitrogen, phosphorus, potassium, so that the extension of the diameter of the branch is maintained at 1.0 to 1.5 cm. Under normal conditions, for every 100 kg of peaches produced, 0.7-0.8 kg of available nitrogen fertilizer, 0.5-0.6 kg of phosphate fertilizer, and 1-1.5 kg of potash fertilizer can be traced.
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.
