3 Requirements
3.1 Test materials
Genetically modified organisms, genetically modified organisms, non-genetically modified organisms promoted in the state, and the quality of the raw materials should be suitable for 1107.3 Requirements for the production of genetically modified organisms: 3.2 Recording of data
3.2.1 Name and location of the test
Record the name of the test site and the location of the test, and use the coordinates of the test site or the global positioning system (CPS> control standard). Draw a micrograph,
3.2.2 Soil data
Record soil type, soil fertility, drainage conditions, soil related plants and other contents. 3.2.3 Ecological type of the experimental site and record the conditions of the experimental site and other crops cultivated, as well as the names and hazards of common diseases, insects and local insect pests. 3.2.3.2 Agricultural ecological type Record the conditions of the experimental site and other crops cultivated, as well as the names and hazards of common diseases, insects and local insect pests.
3.2.4 Meteorological data
Record the daily wind speed, daily rainfall (m) and duration (H) of the test period. Temperature and humidity (H) are displayed in the form of "table". Record the test results during the test period. For example, the test results may be caused by long-term changes in production, early harvest, fragrance, etc.
3.3 Test control measures
3.3.1 Isolation conditions
The test site shall not be completed within 500r of planting. 3.3.2 Isolation measures
Plant non-flower crops as the separation zone, and the area shall be tested in a small format. Designate a special person for the benefits of 3

3.3.3 During the test, if the test materials are found to be stolen, they should be abandoned in accordance with the provisions of the law. The competent department of the test and the local public security department should be informed immediately. 3.3.4 Handling of test materials: The test materials should be transported and kept by a designated person. After the test, except for the materials to be retained, the remaining test materials should be discarded. 3.3.5 Conclusion of post-test inspection tt||The license test reached the boundary benchmark ratio: the current year and the next year, no subspecies of vegetables and ten academic flowers, use special personnel to ensure stable non-marketable genetically modified forest seedlings
4 Trial method
4.1 Seed germination rate inspection
variable E, "334X, implement the prescribed method
4.2 Seed viability test
According to this group of test plans, shallow burial and deep burial (and after (months! Months, each variety needs to be repeated,! 3, the age of the product can be quickly seeded H The name and number of the variety were marked on the mirror and packaged in the Japanese version. The soil was filled with soil and the samples were taken from the mountain for testing after 6 and 13 months. The variance analysis was performed on the penetration rate. 4.3 Inspection of the ability of the crop to grow crops
4.3.1 Trial design
The agricultural team conducted a trial in a diversion area and set up a random group design. The recipients of the genetic oil were collected from three local non-genetically modified varieties. The research package was 4.3.2 Planting
The sowing time of winter vegetables was 0 to 1 day before, and the rapeseed area was 2. The experiment was conducted on wasteland before and after 15F. The actual germination rate was 16/m2. The key area was sown with the most seeds/m, and the width of the area was 12/m2. 4.3.3 Experimental management
No training management was conducted during the experiment. The experimental area was marked with a regular training method. After the harvest, the plots in each area were shaded and transplanted according to other materials. In January, the plots were marked with a regular training method. The plots in each area were shaded and transplanted according to other materials. The plots in each area were stored in the cold weather and the types of crops were required in March of the next year. 3.4 Adjustment records
The first, in December, the party promoted the ban, and the Shantou district in June to check the effect of the plants, the second winter rapeseed area in December, the rapeseed area in each plot to measure the number of survival, .3.5 Cross-table
