A new method to replace the whitening of fruit trees—reflective bandaging

A new method of winter cold protection for trunks—reflective bandaging, which is mostly used for 1-5 year-old young trees, and can be carried out from late October to late November. The material is made of white plastic woven bags to wrap the trunk and large branches tightly, focusing on the south of the trunk and large branches. The cold protection materials will be removed in mid-to-late April of the following year. The white plastic woven bag sheet mainly uses its white color to refract the sunlight shining on the trunk, thereby reducing the temperature difference between day and night on the surface of the trunk to achieve the effect of cold protection. According to the thickness of the trunk, the plastic woven bag can be cut into 5-10 cm wide and 120 cm long cloth strips (the thicker the trunk, the wider the cloth strips), spirally wrap up the base of the trunk, and seal tightly. Fix it at the branch above the tree (use tape, staples or fine wire to fix it).

Advantages of reflective dressing to prevent cold

1. Convenient to obtain materials. Reflective wrapping method mainly uses white plastic woven cloth. There are a large number of waste fertilizer bags and feed bags in the countryside. The main materials are plastic woven fabrics, which are cut into strips, and the white side with no pattern is outwards and can be wrapped on the trunk. You can also go directly to the plastic woven fabric manufacturer to order the width of the cloth strips, and the effect will be better. Calculated according to the specifications of 10 cm wide and 120 cm long plastic woven cloth, the cost of each piece of cloth is 0.10-0.15 yuan, and the price is quite low.

2. Simple operation, saving labor. The reflective bandaging method is very convenient to operate, and one person can complete the bandaging work of a tree in 30-50 seconds. An ordinary labor force can easily complete the task of dressing 300 to 400 fruit trees in a day.

3. The operation is not restricted by time and weather factors. Compared with white coating, the reflective bandaging method can be operated for nearly two months from mid-October to late November. It can be operated regardless of whether the temperature is above or below zero, rain or snow, and there is no need to worry about the problem of cold protection material falling off. .

4. Obvious effect and lasting effect. From the end of October to the completion of the dressing, to April of the following spring, the dressing will continue to exert its cold-proof and reflective effect, with a long-lasting effect and obvious effects. 5. The cold protection material can be reused, saving production costs. After the temperature rises and stabilizes in the spring of the second year, the bandage strips can be unwrapped, collected, sealed, and placed in shading for recycling in the next winter, thereby saving material costs.

6. Avoid orchard pollution. Adopting the trunk reflective dressing method, the dressing material can be recycled and will not cause any pollution to the soil environment of the orchard, which is beneficial to protect the environment, reduce pesticide residues, and produce green fruits.

ELISA Analyzer

Processing high-throughput samples, intelligent reuse for large-capacity publishing, work surface: 200cm, 8 sample injection needles, 12 temperature-controlled incubation positions, 12 room temperature incubation positions, 32 plate storage positions, Sunrise microplate reader, HydroFlex plate washer, up to 512 specimens, sequential loading of samples, reagents, microplates Parallel loading of up to 6 plates for fast dispensing.

The automatic enzyme immunoassay analyzer is based on the principle that the enzyme and the substrate can produce a color reaction, the absorption lines of different substances have different characteristics, and strictly abide by the Lambert-Beer law, quantitative and qualitative analysis of substances. instrument. The method of analyzing the content of various enzymes such as antigen or antibody generally mainly adopts colorimetric method. In practice, spectrophotometry is the basic working principle of an automatic enzyme immunoassay analyzer. The light emitted by the light source lamp becomes a beam of monochromatic light after passing through a filter or a monochromator. The monochromatic light beam passes through the sample to be tested in the microtiter plate, and part of the monochromatic light beam is absorbed by the sample and reaches the photodetector. The intensity of the light signal projected on it is converted into the magnitude of the electrical signal by the photodetector. This electrical signal is processed by pre-amplification, logarithmic amplification, analog-to-digital conversion, etc., and then sent to the microprocessor for data processing and calculation, and the test results are output by the display and printer. The microprocessor completes the movement in the X and Y directions of the mechanical drive through the control circuit.
The automatic enzyme immunoassay analyzer adds the sample to the microwells of the pre-coated antigen or antibody microtiter plate, washes after the reaction, removes the unseparated ligand, then adds the enzyme isolate, after incubation, washes again , remove the unseparated compound, and then add the enzyme substrate, after the reaction, the colored final product is formed, and the stop solution is added to stop the reaction. The absorbance of each microwell of the microtiter plate is read by the wavelength that has been set by the spectrophotometer. The concentration value of the analyte in the sample is calculated by the absorbance value of the sample and the standard curve, so that the quantitative result can be obtained, or the absorbance of the sample is compared with that of the standard product, so that the positive or negative qualitative result can be obtained.
