Citrus Winter Cricket Pruning

2024-03-24 10:08:27

Answer: Pruning of citrus before winter and spring must be done after fruit picking and before spring germination the following year. Freezing damage is usually carried out in mid-February. Juvenile trees should be lightly cut, and purposely cultivate 3 to 5 main branches with even distribution. Sub-main branches should be reasonably arranged on the main branches, and the main branches should be kept extended to eliminate the clumps, dense branches, diseased and insect branches, The late autumn shoots were cut off; the resulting tree was pruned using the technique of "one opening, two sparse, three shrinking". Saw the upright branches, open the skylight to reduce the crown height; thin out or cross the large branches, use the rope to open the upright branches to open the canopy; cross-sealed the trees, shrink and renew, leaving 20 cm between the rows of shrinkage. Create a highly productive tree shape that is airy and light, with three-dimensional results.

Drug Of Abuse Tests

AMP/BAR/BZO/BUP/COC/THC/MTD/mAMP/MDMA/MOP/OPI/OXY/PCP/PPX/TCA Available with Specimen Validity Tests (S.V.T.) for: Oxidants/PCC, Specific Gravity, pH, Nitrite, Glutaraldehyde and Creatinine One step, rapid screening tests for the qualitative detection of drug(s) and drug metabolite(s) in human urine. For in vitro diagnostic use only.Drug Tests (Strip/Card/Device/Cup) is a lateral flow chromatographic immunoassay designed to qualitatively detect the presence of drugs and drug metabolites in human urine

Drug Tests (Strip/Card/Device/Cup) provides only a preliminary analytical test result. The test is not intended to be used in monitoring the drug levels. A more specific alternate method must be used in order to confirm the test result. Gas Chromatography/Mass Spectrometry (GC/MS) is the preferred confirmatory method. Clinical consideration and professional judgment should be applied to any drug of abuse test results, particularly when preliminary positive results are obtained.

INTERPRETATION OF RESULTS
Positive: One colored line appears in the Control zone (C). No line appears in the
Test zone (T). The absence of a line in the test region (T line) indicates a positive result.
The positive result indicates that the drug level is above the detectable level.
Note: The samples with positive results should be confirmed with more specific method.
Negative: One colored line appears in the Control zone, and another colored line
appears in the Test zone. The negative result indicates the drug or its metabolite level is
below the detectable level.
Invalid: No line appears in the Control zone. If no C line or no C line and T line
develop within 5 to 10 minutes, the test is invalid. The test should be repeated with a new
test device. Insufficient specimen volume or the incorrect procedural techniques are the
most likely reasons for invalid result. Review the procedure and repeat the test using a
new test strip or device. If the problem persists, discontinue using the current lot and
contact your suppliers.
ADULTERATION INTERPRETATION
(Please refer to the color chart, if applicable)
Semi-quantitative results are obtained by visually comparing the reacted color blocks on
the strip to the printed color blocks on the color chart. No instrumentation is required.
QUALITY CONTROL
1. Built-in Control: the test contains a built-in control feature, the C line. The presence of
the C line indicates that the test is performed properly. If a C line does not form, the test is
considered invalid. In this case, the testing should be repeated with a new drug tests.
2. External Quality Control: Control materials are not supplied with this kit. However, it is
recommended that positive and negative controls should be tested as good laboratory
practice to confirm the test procedure and to verify proper test performance.
