The excellent new variety of Xixi Pomelo, Hongmeimei pomelo, was a new pomelo variety developed from Pingxi County in Fujian Province. The pomelo was selected from the non-major crop variety identification committee of Fujian Province in 2006 ( (2006006).
1〠Characteristics of red meat grapefruit varieties
Red pomelo grapefruit has inherited the maternal? Ximi pomelo has a wide adaptability (can be planted in the extreme minimum -5 °C area), put into production early, high yield performance, resistance to diseases and insect pests, easy cultivation and management and other excellent characteristics: also Keeps the pomelo fruit shape smooth and beautiful, with large skin and thin skin, no seeds in the pot, soft and juicy fruit juice, no residue, juice tomato with red tomato pigment and carotene higher, favored by consumers, fresh fruit market In the past three years, the market price per kilogram was between 10-30 yuan, which is 5-15 times higher than that of ordinary pomelo, and the market prospect is promising. From 2006 to 2009, there were more than 100,000 strains introduced into and out of the province by fruit farmers. The prunes, leaves, flowers, and fruits of red pomelo are similar to those of prunes, and the different characteristics are: (1) early maturing varieties; (2) purple flesh; (3) red flesh honey pomelo The fruit shape of the put-in tree is relatively large, and it is sensitive to nutrients and trace elements such as organic matter, potassium, calcium, magnesium, and boron. There are many fissures in the flesh, and some of them are lignified. As the tree age and the amount of fruit production increase, they increase. Application of organic fertilizer and trace elements supplemented with calcium, magnesium, boron, zinc, manganese, molybdenum, copper, iron, etc., cracking, cracking, and lignification are gradually reduced.
2, red meat, pomelo pollution-free high yield and quality cultivation techniques
2.1 Selection and cultivation
Red pomelo can be grown in areas suitable for planting pomelo. In order to enable red meat and pomelo to achieve early production, high yield and stable production, extended production life, should choose a deep soil, loose soil and fertility, irrigation and irrigation conditions are good, adequate lighting, open land (land) or hillside. Trees and high altitude fog are not suitable for planting in mountainous areas.
Red pomelo grapefruit planting season is suitable for spring planting and autumn planting. Winter planting can also be carried out in areas with higher winter temperature. Spring plants can be planted in the early spring before the spring shoots and the late spring after the spring shoots are turned green (before and after Qingming); autumn plants can be planted from the "Liuqiu" to the "cold dew" seasons. Planting seedlings can be planted directly by grafting seedlings, and nutrient bags can also be used for transplanting after centralized planting. High-risk varieties are generally suitable for autumn and winter seasons before or after autumn or winter, and the success rate of cutting or abdominal connection is higher.
2.2 Fertilizer Water Management
20-30 days after the planting of red meat and pomelo, after the new roots and shoots germinate, the eight effective forms of modern agriculture are promoted by Taiwan Xingon Super Concentrate Organic Liquid Fertilizer "Te Yougen" 300-500 times plus Gao Li Da Gao Ka 1000 times the root irrigation solution 2-3 times, every 10-15 days pouring 1 time. Young trees apply 0.5 kg of nitrogen, phosphorus and potassium tricomponent fertilizers and 1-2 kg of organic fertilizers per plant before and after pomelo tip, and foliar roots are sprayed with Gao Lida high calcium liquor 1500 times plus magnesium, boron and manganese. Trace elements such as foliar fertilizers promote root development and rapid expansion of the crown. Entering fruiting and fruiting period, it can apply organic fertilizer and ternary compound fertilizer according to the amount of fruit in spring shoot, young fruit period and middle fruit period.
2.3 Tree Management
Red-fruited pomelo young trees promoted the development of the root system, expanded the canopy, and started production as early as possible. In the underground area, the three-guarantee orchards for water retention, soil conservation, and fertilizer maintenance were established to promote the vigorous growth of the root groups. Shoots were picked, pulled, digged, and trimmed using the method of "maintaining the main branch, leaving the crown to expand and branching, leaving the short-result parental branch." The upper part of the crown was trimmed, the lower part was cut off, and the inside of the crown was trimmed. The crown was cut less. Outside; trimmed long branches and cut old Zhuang branches: Trimming upright branches, cut down the long branch of the "three stay four cut" method to cultivate good light transmission. The stumps are thick and the result is a large, short, and strong productive canopy.
Red meat and pomelo was put into the production period, and the strong fruit trees were moderately circumcised or girdled during the “small snow†to “big snow†seasons, which promoted the transfer of strong fruit trees from vegetative growth to balanced development of reproductive growth.
2.4 Pest Control
The main diseases and pests of red-fleshed pomelo are: anthracnose, maculopathy, canker, scab, black rot, scab, leaf miner, red spider, whitefly, rust tick, scale insect, aphid, etc. The characteristics of the occurrence of diseases and pests should be mastered, and comprehensive control measures should be taken.
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.
