Field Practice 3
3.1 preparation before spraying
3.1.1 require spraying plots set aside the test area, the length of the test area according to forward speed, the spray rate and spray volume to determine, but not less
To 30m. Testing time less than 15s, and the liquid inside the liquid volume of not less than 10% of tank capacity. So spray the whole area of \u200b\u200b0.1hm2
Several times. The results are reported in Table B. 1.
3.1.2 Depending on the growing season and pests, select the appropriate pesticides and spray methods.
3.1.3 The recommended dosage according to the approved registration of pesticide binding plots conditions, spray volume to determine and implement forward speed.
3.1.4 spray volume and the amount of spray nozzles, spray width and forward speed spraying operation relationship according to formula (1); according to the selected spray volume, before
Forward speed and the number of nozzles, according to the formula (2) calculate the amount of a single spray nozzle required.
3.1.5 spraying herbicide recommended working pressure is less than 0.3MPa; spraying of insecticides, fungicides recommended working pressure of 0.3MPa ~
0.5MPa.
3.1.6 spraying of insecticides, fungicides recommended when using cone fog nozzles; recommend using flat fan nozzles spraying herbicide; between the upper row or in addition to
Recommended Use flat fan nozzle at a uniform type of grass.
3.1.7 Use spray sprayer must use rod equipped with anti-drip valve nozzle when spraying herbicides.
3.1.8 according to the amount of spray nozzles spray width, forward speed and calculate the required spray volume, and then depending on the desired amount of spray nozzles and the recommended working pressure
Select the appropriate nozzle.
3.1.9 Evaluation instruments should be calibrated, and within the effective period, see Appendix A.
3.2 sprayer (unit) performance check
Sprayer (filter) should meet the NY/T 650-2002 requirements in 4.1.1, according to JB/methodological and T 9782 into the following requirements
