3 Definitions
This standard adopts the following definitions:
3.1 Tillage depth
Operation scale, distance between the bottom tillage layer and the upper tillage surface; 3.2 (Equivalent) depth
Distance between the support (rolling) layer and the visual surface after the tillage (waste) operation. 3.3 The work of loosening, leveling and extinguishing the surface of the field using picking marks. 3.4 Grape cultivation
Except for the technical consultation of the mouth,
The average number of cuts of the mother plant: 3.6 The return rate
The length of the half-length of the dance fortress
3.7 The vertical length of the average length of the system:
3.8 The amount of vegetation left on the ground after the tillage or (acid) operation, and the quality of the residual waste on the ground. 3.9 The difference between the surface of the driving layer and the water surface after the slurry operation. 3.10 Slurry density
The degree of water-soil mixing after the water-slurry operation, expressed by the density of the slurry. Approved by the Ministry of Agriculture of the People's Republic of China on January 4, 2002, and implemented on February 1, 2002
3. 11 Negative residue
NY/T 501-2002
After the negative residue is discharged or the operation is carried out, the effective density of the sand surface shall be 4 operation quality indicators
4.1 The actual operation quality indicator values ​​of this standard shall be determined by the following operating conditions: the output of the above-mentioned standard shall not be greater than 5×1)Pa, the quality of medium or light sticky fertilizer shall not be greater than 22k/hm*, the height and width shall be less than 30m (before the operation, the elasticity shall be evenly distributed on the surface) or less than 7b5kg:hm; the depth of water mixing shall not be greater than 3em: surface water 35cm: 4.2

5.1 Sampling method
Take the midpoint of the length and width of the square of the land and select 2 of the diagonals as the test sample. 5.2 Testing point location
Pick the diagonal of the test sample (pool), and after determining a number of samples in the range of one quarter to one eighth of the diagonal length, wait for the midpoint of the diagonal to be determined, and then determine the positions of the 4 testing points. 5.3 Determination of the missing rate: Select a row from the inspection grid, and calculate the missing rate by taking the product of the points and the area of ​​the inspection block. (1) In the formula, the missing rate is 1, where the area of ​​the first row point is 1-the area of ​​the inspection block. m\

type operation, randomly select three soil strips with a length of not less than 15m in the sample water, and measure the ten-point softness, broken strip (the number of strips broken in the tillage direction, the vertical strip that turns 90°±1) and the length of the strip that turns over (or turns back to the bottom of the grid) respectively, and calculate according to formula (2)-formula (5): B=:XＲ
support: R-
point rate depth, m: soil strip depth at the point after
type tillage operation, each soil strip is measured at a rate correction system, and the value is 1.1:5~1.10; D
break number:
first: the number of broken strips in the above system, the length of the strip and
t||, the length of the first soil strip and the length of the second soil strip; H,—the length of the second soil strip.
5.5 Determination of the depth of the soil
Determine the distance from the soil surface to the bottom layer (part) of the soil surface. Depth: 10 points are measured every 15m, and a total of one trip,
26 Determination of the tillage depth
In the test area, measure the tillage depth or the tillage depth, and the qualified tillage depth rate is the percentage of qualified depth points in the total number of tillage depth points. 5.7 Determination of the surface leveling
Measure 3 points at equal distances along the two diagonals in the whole land, taking the water surface as the reference, and measure the distance from the surface to the water surface of the points. According to formula (6) and formula (7), calculate the average value and standard difference, and take the standard as the leveling 6)

5. Determination of soil fragmentation rate
Collect soil fragments at each measuring point in the measuring area at a depth of 2.5mx0.=m and count the number of soil fragments with a depth greater than m and calculate the average value of the soil fragments at the measuring point.5.9 After the residual test, in the measuring area, collect the residual soil in the pool according to an area of ​​1m at each point and calculate the average value. 5.1D Determination of soil fragmentation
Immediately after separation, measure the overall quality of each measuring point in the measuring area and collect the average value as the soil fragmentation rate. 6 Inspection rules
NY/T501—2002
