Strawberry/Watermelon - Post-season Rice Stereo Planting Model

This planting mode is mainly suitable for the suburbs of large and medium-sized cities, which is more than double the economic benefits of the wheat and rice crops. The planting method is: a combination of 530 centimeters wide, 300 centimeters in the middle to build three 100 centimeters wide high ridge, ridge height 25 centimeters, ridge bottom width 67 centimeters, furrow width 33 centimeters. Leave a line for each side on each side. In mid-October, plant two rows of strawberries on each ridge, spaced 23 centimeters apart, with 16.5 centimeters of plant spacing, and about 5,500 plants per 667 square meters. In late April of the following year, the melon seedlings cultivated in the Gualou Road are reserved for planting and cultivation. The planting distance is 50 centimeters, about 600 per 667 square meters, covering the mulch. After harvesting of strawberry fruit in late May, depending on soil fertility and fertilization, the extracted strawberry plants can be transported by 50%, leaving 50% buried in the melon field, and then the high ridge of the strawberry leveled, in late July, after the watermelon pulled out together Plowing the soil preparation can be transplanted or post-planted rice. The matching technology of this planting pattern, the first strawberry to choose four or more than four leaves, a single plant about 30 grams of fresh weight, the roots of the developed seedlings, timely planting early to ensure strong seedlings overwinter. General requirements in the middle and late October to grab transplants before the rain. If it is sunny, plant seedlings in the afternoon and reduce the number of burns to increase the survival rate. After planting, the temperature of the plastic film can be increased by 7-10 days in advance, and the harvest period can be extended by 18-20 days. Cover film time is generally controlled in the first cold 1-2 days after that year, in the second half of February the following year, the hole in the film is ventilated and ventilated, and in the first half of March, the film breaks through the hole and raises the hole. Secondly, basal fertilizer is generally applied 50 kg of compound fertilizer, 10 kg of urea, and 1,000 kg of fully-fertilized organic fertilizer per 667 square meters for ridges, and 50 kg of vegetable cake, preferably with higher potassium content. Strawberry fields generally do not need topdressing in the spring, but for strawberry fields with poor soil quality, weak growth, and lighter leaf color, urea solution with a concentration of 0.3% can be sprayed 2-3 times from buds to young fruit. In addition, the common insect pest in strawberry fields is red spider, which generally begins to damage in late April. It can be used to control 20% of pyrethroid 500 times. In addition, gray mold is a major disease of strawberry, can be used 50% carbendazim 1000 times or 50% quickening WP 200 times better control, at intervals of 5-7 days, continuous staggered use.

Auto Chemistry Analyzer

The automatic biochemical analyzer is an instrument that measures a specific chemical composition in body fluids according to the principle of photoelectric colorimetry. Due to its fast measurement speed, high accuracy and small consumption of reagents, it has been widely used in hospitals, epidemic prevention stations and family planning service stations at all levels. The combined use can greatly improve the efficiency and benefits of routine biochemical testing.
principle
The automatic analyzer is to automatically run all or part of the steps of sampling, mixing, warm bath (37°C) detection, result calculation, judgment, display and printing results and cleaning in the original manual operation process. Today, biochemical tests are basically automated analysis, and there are fully automatic biochemical analysis systems designed for large or very large clinical laboratories and commercial laboratories, which can be arbitrarily configured according to the laboratory's testing volume.
Whether it is the fastest-running (9600Test/h) modular fully automatic biochemical analyzer today, or the original manual-operated photoelectric colorimeter for colorimetry, the principle is the use of absorption spectroscopy in spectroscopic technology. It is the most basic core of the biochemical instrument.
Optical system: is a key part of ACA. Older ACA systems used halogen tungsten lamps, lenses, color filters, and photocell assemblies. The optical part of the new ACA system has been greatly improved. ACA's beam splitting system can be divided into front splitting and rear splitting due to different light positions. The advanced optical components use a set of lenses between the light source and the cuvette to convert the original light source. The light projected by the lamp passes through the cuvette to bring the beam to the speed of light (unlike traditional wedge beams), so that the spot beam can pass through even the smallest cuvette. Compared with traditional methods, it can save reagent consumption by 40-60%. After the spot beam passes through the cuvette, the spot beam is restored to the original beam through this group of restoration lenses (wide difference correction system), and is divided into several fixed wavelengths (about 10 or more wavelengths) by the grating. The optical/digital signal direct conversion technology is used to directly convert the optical signal in the optical path into a digital signal. It completely eliminates the interference of electromagnetic waves to the signal and the attenuation in the process of signal transmission. At the same time, the optical fiber is used in the signal transmission process, so that the signal can achieve no attenuation, and the test accuracy is improved by nearly 100 times. The closed combination of the optical path system makes the optical path without any maintenance, and the light splitting is accurate and the service life is long.

Constant temperature system: Since the temperature of the biochemical reaction has a great influence on the reaction results, the sensitivity and accuracy of the constant temperature system directly affect the measurement results. The early biochemical instruments used the method of air bath, and later developed into a dry bath with constant temperature liquid circulation which combines the advantages of dry air bath and water bath. The principle is to design a constant temperature tank around the cuvette, and add a stable constant temperature liquid that is odorless, non-polluting, non-evaporating and non-deteriorating in the tank. The constant temperature liquid has a large capacity, good thermal stability and uniformity. The cuvette does not directly contact the constant temperature liquid, which overcomes the characteristics of the water bath type constant temperature being susceptible to pollution and the uneven and unstable air bath.

Sample reaction stirring technology and probe technology: The traditional reaction stirring technology adopts magnetic bead type and vortex stirring type. The current popular stirring technology is a stirring unit composed of multiple groups of stirring rods that imitate the manual cleaning process. When the first group of stirring rods is stirring the sample/reagent or mixed solution, the second group of stirring rods performs high-speed and high-efficiency cleaning at the same time. The set of stirring bars also undergoes a warm water washing and air drying process at the same time. In the design of a single stirring rod, a new type of spiral high-speed rotating stirring is adopted, and the rotation direction is opposite to the spiral direction, thereby increasing the stirring force, the stirred liquid does not foam, and reducing the scattering of light by microbubbles. Reagent and sample probes are based on the principle of early capacitive sensing, but slightly improved to increase the alarm of blood clots and protein clots, and re-test results according to the alarm level, reducing sample aspiration errors and improving the reliability of test results. . Large-scale biochemical instruments can detect more than 1,000 tests per hour, so automatic retesting is very important. Subjective evaluation of test results and manual retesting can no longer meet clinical needs.

Other aspects: barcode recognition of reagents and samples and computer login. Due to the lack of barcode recognition function of early biochemical instruments, there are more opportunities for errors. In recent years, both imported and domestic chemical instruments have adopted barcode detection. The use of this technology in biochemical instruments has provided technical support for the development of high-speed ACA, and also made the instrument quite supportive. The software development is simple and easy, therefore, barcode detection is the basis for the intelligence of the instrument. Open reagents, as an important factor for hospitals to choose models, whether the instrument supports open reagents is very important. After the reagents are opened, hospitals and scientific research units can choose their own reagent suppliers, and have a greater degree of freedom in measuring the price, the reliability of the test results, and the validity period of the reagents. Ion Selective Electrode Analysis Accessory (ISE), human serum and urine electrolyte indicators are very important, and hospitals can save money by adding ISE to the ACA system.
