2, topdressing: use 0.5 kg of borax per acre to mix 10-15 kg of fine dry soil, carry out soil topdressing in cotton seedling stage, or mix with chemical fertilizer evenly, and ditch or dig a hole 7-10 cm away from cotton seedlings. Give it down.
3. Manual spraying: use 0.2% borax aqueous solution or 0.1% boric acid aqueous solution in the cotton bud stage, spray once in the initial flowering stage and flowering and ringing period, and the spray volume is 50-80 kg per acre.

Circular grid resistance Strain Gauge is a kind of sensitive element by using resistance-strain effect to transform the strain of specimen into resistance change. It is the most widely used strain test element. The load cells used in weighing and measuring field mainly include resistance strain gauge type load cells, capacitance type load cells, vibrating string type load cells and so on, most of them are resistance strain gauge type load cells.
The resistance strain gauges produced by our company has the advantages of long liability and good uniformity, the functions of creep and temperature self compensation, suitable for batch production of alloy steel, aluminum ally and stainless steel load cells with high accuracy, and for producing other load cells and force and strain measuring elements.
