Change measures orchard spraying

1 change spraying habits, improve the quality of spraying fruit trees according to size, leaf number, the reasonable control of water, spraying should be uniform thoughtful, top to bottom, from the inside to the outside, to be sprayed into the back of the blade is liquid, not leak spray, can not re-spray to fully wet leaves, it will not form a flow drops as well, do not leak ulterior motives, leaf with drugs, do not stream does not drip.

2 Improved spraying measures to improve the atomization First minimize the use of manual trigger sprayers, hand sprayers not only labor-intensive, inefficient spraying slow, but pressure is small, poor atomization. Second, the replacement of the spray gun are used, only one injection hole of the lance into two or three of the nozzle orifice, so that good atomization, spraying uniform, no harm to the fruit surface.

3 master spraying techniques to improve spraying sprayer spraying techniques to properly balance the pressure, the pressure is too small, poor atomization; too close, easy to stab the fruit surface. Friends of farmers must be clear, when spraying high-pressure liquid through the orifice after, to go through a distance of 40 cm to completely atomized, so the hand sprayer spraying nozzle and crops must be kept at a distance of about 50 cm. Fog cone angle increases, the finer droplets, on the contrary, the smaller the angle cone fog, mist thicker. Remember, the size of the spray pressure, nozzle angle and distance with the crop is directly related to the liquid spill Tut uniformity and the extent of coverage is good or bad.
