5.2 Preparation
NY/T6502002
5.2.1 According to the crop type, growth period, crop seed structure and landform conditions, correctly select the operating machinery and tools: 5.2.2 Adjust the operating tools to the correct working condition, use clean water for trial operation, and accurately reduce the quantity and work plan for temporary treatment 5.2.3 Register the types of crops and households for correct selection of agricultural products 5.2.4 Before purchasing pesticides! The requirements of the traditional agricultural use should be met in the month, and the hardness of the month should be small. The safe use of the surface pesticide should be in accordance with the period of B428. The degree of safety protection during operation should be guaranteed. 5.2.5 In the 1 working width, the benchmark should be erected. The working width should be free of charge. There should be a time between the original full spraying) (year legacy): 5.3 The coverage rate of the liquid should be checked. 5.3.1 Take the distribution of group points. 3) High-quality crops (such as rubber trees, fruit trees), wash two representative airflows, and evenly distribute 1 point in an equidistant plane in each growth, middle and lower years for observation. 4) General crops (such as corn, high fan, flower, rice, small change, etc.) in the middle and late stages of the operation, in each working width range, randomly select a row to help the inspection. Each forest is regulated at its highest point, two-quarters of the plant height (middle) and one-quarter of the plant height.
c! Low case plant Shanqian, peanut and other crop pieces of fungus period), in the annual soil free range, limited milk washing to take a row, still in the line uniformly selected "plants, Chongxian machine observation natural place.
5.3.2 Detection
Use the beat count method to determine. After spraying, before the liquid "husked", also quickly select a leaf at each sweeping point, use the separation method to run, and pass the drug on both sides of the leaf to the situation, graded 32-1,,2
Calculate the liquid barrier density according to the formula (1) about liquid barrier density

5.3 Sampling point distribution:
5.4.2 Testing
Use the paper card method, fix a piece of card at each sampling point, add red to the sprayed medicine. After chewing, take back the paper card and hold it 5 times. Collect the same amount of drops per paper, and ensure the same amount of drops per square meter. 5.5 Testing of uniformity of drop distribution
5.5.1 Sampling
Evenly distribute the points in the operation area, evenly Take 1\ rows at a time, and each row is divided into approximately sections. 5.5.2 Test
5.5.2.1 Conventional test items are tested by light inspection. The main test items are red wine (addition of red wine to the test items) and then the plant sampling is carried out. Several leaves are randomly selected from the top of the crop crown in each sample section as a sample. The samples need to be omitted. Each sample is washed with a certain amount of clean water for 2 hours. The light transmittance of each eluate is determined.The amount of red deposited before elution can be calculated according to the "standard rate" of the red G standard sample. The drug deposition unit is calculated by the relationship between the red G and the 3
NY/T6502002
"deposition equivalent" of the drug used. The area of ​​each sample is used as the weight, and the initial deposition amount of the drug is calculated based on the unit.
You can also use chemical analysis or residual light analysis: the chemical analysis method is to use an analytical instrument to measure the content of the detergent, and then calculate the total amount of the leaf sample. After the spraying method, add fluorescent agent to the spray solution and measure the content of fluorescent agent in the spray solution. 5.5.2.2 Detection of low-volume and ultra-low-volume spraying cases. Low-volume ball penetration and break-off effect of fruit paper are used. In the package, the crown of the crop is filled with red wine. Add 6: After spraying, collect the paper F, observe with a magnifying glass of 5~1 times or more, read the fog number on the piece of paper, and calculate the fog density on the straw paper: 5.5.3 Calculation of the coefficient of difference
) The average amount or average droplet density is calculated according to the formula, E
The sample average and deposition amount or average droplet volume density) is in units of [microgram per centimeter (bar/cm) or drop per meter (droplet]; The effective volume of the sampling point is in units of microgram per square meter (m or full half meter/em:

6.1 Sampling
When the operation is a sheep decision m, the injection block length is inversely charged in the reverse direction, and the blocks are divided into blocks, and a block is randomly judged as a test sample; the business is a customer block H, and the block is selected from the test block as the test sample. 6.2 Unqualified items classification
The items that are tested do not meet the quality requirements of 4.2 and are called unqualified. The degree of impact on the quality of the operation will be The test items are divided into Class A and Class B. The classification of unqualified items is shown in Table 2: Classification of unqualified items 2 Classification of unqualified items Air quality Uniformity and uniformity with the elements Fog deposition Impact on the surface of the fog Machine injury This: The accuracy of the spray toxicity test items is the same as the flow resistance and accumulation of fire-resistant basic spraying. The sampling is divided into the following table. The table is the narrow judgment of the death effect. The table represents the number of combined judgments.
