GB 9478 grain seeding machine test method
3 job quality indicators
3.1 Working conditions
The conditions of the working plot should meet the agricultural technical requirements of the mechanical sowing operation, and the grain should be sown in time during the agricultural period, and the absolute moisture content of the soil.
16% to 24%.
3.2 Quality indicators
When the operating conditions are in accordance with the provisions of 3.1, the quality of grain seeding machinery operations shall comply with the requirements of Table 1.
Table 1 Quality indicators of grain seeding machinery operations
Serial number item quality index
1 Dispersion coefficient of variation of each row/(%) ≤ 3.9
2 Total displacement stability coefficient of variation/(%) ≤ 1.3
3 sowing depth pass rate/(%) ≥ 75
4 Total seeding rate deviation rate/(%) ± 2
5 Total fertilization rate deviation rate/(%) ± 3
6 Single row spacing deviation/cm ±1
7 Reciprocating adjacent row spacing deviation/cm ± 5
8 Straightness deviation rate/(%) ≤ 0.1
9 Covering rate/(%) ≥ 98
10 broken rate/(%) ≤ 2
4 job quality testing methods
4.1 Dispersion coefficient of variation of each row, coefficient of variation of total displacement stability, yield of seeding depth
According to the provisions of GB 9478, the determination of the consistency of each row, the determination of the total displacement stability and the determination of the depth of seed cover. Calculation
The row uniformity variation coefficient, the total displacement stability coefficient of variation, and the seeding depth pass rate.
4.2 Total seeding rate deviation rate
According to the total seeding amount and the corresponding planting area, calculate the actual seeding amount per hectare, and calculate the total seeding rate deviation rate according to formula (1).
