First, the storage and harvesting methods of varieties Red meat varieties (such as Dahongpao) than white meat varieties resistant storage, late-maturing varieties than early, medium-maturing varieties of good storage. The store's clams are suitable for ripening. It is not good for storage too early or too late. Fruit picking must be done with scissors, gloves, and cutting. The shorter the fruit stems, the better. Pay attention to the lightness of the skin and don't hurt the epidermis.
Second, preservative treatment before storage Pre-storage with 0.1% carbendazim solution dip fruit 2 to 3 minutes, can also be used 0.1% carbendazim plus 0.02% of 2,4-D mixed liquid dipping fruit for 2 minutes, and then remove and dry Dry, into the bottom of the pad with a shredded paper or box, each basket (box) limited to 15 to 20 kg of fruit, the conditions of the available plastic wrap single fruit packaging.
3. Clean the cellar before storage, then put the utensils in the cellar, spray it with 40% formalin, or burn and fumigate with 20 g/m3 sulfur powder for 24 hours, then open the cellar door and into , vents, the boxed weights in the pit. General code 垛 4 ~ 5, between the 垛 and 需 need to leave a gap. At a temperature of 20°C and a relative humidity of 85% to 90%, this method can be used for about 25 days. If a plastic bag is punched in the outer casing of the box, the storage effect is better.
Fourth, the ditch is selected to facilitate the management of no-mouse, insect-free and no livestock harm in the cool, dry place, dig deep 1 to 1.5 meters, width 1 to 1.5 meters, length 10 to 15 meters of the ditch, ditch bottom shop 6 ~ 7 centimeters of clean and fine wet sand (humidity is suitable to be dispersed after being pressed into a group by hand), and then the fruit box with rake is placed in the ditch, and a perforated plastic film is used for the ditch. Cover and finally ride a pergola along the ditch. This method can be stored for 25 to 30 days under 20°C and 85% to 90% relative humidity.
V. Simple air-conditioned storage of plastic film Store the preserved fruit in a ventilated place for 2 days, then pack it in a 0.02 mm thick polyethylene film bag, place it in a box, and place it inside the box. A perforated polyethylene bag (8 holes with a diameter of 1.5 cm per bag) can be tightly closed and stored at a temperature of 3 to 8°C and a relative humidity of 85%. Months.
Principle
The test utilizes antibodies including a monoclonal LH-β antibody and goat anti-rat IgG on the
nitrocellulose membrane with colloidal gold marked anti-LH-α monoclonal antibody as an mark
tracer. The reagent is used to detect the LH in urine according to the principle of double antibody
sandwich method and gold immunochromatography assay.
Main components
The testing kit is in the form of strip, cassette, and midstream. Basic components: Sample pad,
colloidal gold marked pad, nitrocellulose membrane, absorbent paper and PVC board. Colloidal
gold marked pad coated with LH-α monoclonal antibody, nitrocellulose membrane coated with
LH-β monoclonal antibody,control line coated with goat anti-rat IgG.
Result Judgment
POSITIVE: Two distinct red lines appear. If the color of testing line is stronger than or equal to the
control line, it demonstrates that the ovulation is about to occur in the next 24 to 48 hours.
NEGATIVE: One red line appears in the control region(C). Or both red line appear with the color of
testing line is weaker than the control line, it demonstrates that the ovulation period does not
arrive yet.
INVALID: No red lines appear or control line fails to appear, indicating that the operator error or
reagent failure. Verify the test procedure and repeat the test with a new testing device.
