Soil testing and formula fertilization is an important means and method for advancing the development of agriculture in the modernization and scientific process. In addition to the use of scientific instruments and other instruments, it also needs to pay attention to propaganda methods and methods so that more grass-roots farmers can understand and understand.
1, publicity
Publicity and training use modern media such as TV, Internet, radio, newspapers and periodicals, wall advertisements, etc., holding a meeting of heads of households, training sessions, distribution of clear papers, recommendation cards for fertilization, questionnaires on the use of formula fertilizers, etc., promotion of soil testing and fertilization The effectiveness of improving efficiency, improving quality, increasing production, protecting the environment, and sustaining development has changed the long-term practice of farmer blindness and uncertainty.
2, important significance
2.1 The application of soil testing and formula fertilization technology will greatly influence the growth of fertilizer demand.
A large number of survey results show that China's current excess fertilizer and inadequate coexistence, excessive fertigation in some areas is serious. The promotion of soil testing and formula fertilization technology is to solve these problems and make the fertilization tend to be reasonable, which will inevitably reduce the growth of fertilizer demand. According to calculations, if the nitrogen fertilizers in areas with excess wheat, corn, and rice are reduced, they will just be able to meet the demand for nitrogen fertilizers in the original areas.
2.2 Soil Testing and Formula Fertilizing Technology Extension Will Change the Ratio of Nitrogen, Phosphorus and Potassium Fertilizers
From the perspective of farmers' fertilization status, the most serious problem of excess fertilizer is nitrogen fertilizer, followed by phosphate fertilizer. Therefore, the application of soil testing and formula fertilization has different effects on N, P and K, which may reduce the proportion of nitrogen fertilizer and appropriately increase the proportion of potash fertilizer. The promotion of soil testing and formula fertilization technology may change China's chemical fertilizer supply system.
For a long time, our country has taken the chemical synthetic fertilizer supply system. With the promotion of formula fertilization technology, the proportion of mixed compound fertilizer will gradually increase, and the supply of basic fertilizer will develop rapidly. The promotion of soil testing and formula fertilization technology will promote the reform of China's fertilizer marketing system. The soil testing and formulating fertilization project will formulate the fertilization formula for the main crops at the county level through the determination of large-scale soil nutrients and field experiments, and publish it to the public. This will promote the construction of agrochemical service system for fertilizer companies. Fertilizer marketing will be combined from simple sales of fertilizers to fertilizer sales and technical services.
Introduction
Holter ECG Monitoring Systems adopt 12-lead system of international standard, which can continuously record ECG waveform for 24-hour and analyze ECG waveform by the PC software. It is applicable for use in medical institution and community.
Analysis Software Function
1.The rate of checking RR wave up to 99.9%, which increased the accuracy of analysis without losing wave.
2.AI histogram function which can directly distinguish various abnormal ECG which can analyze faster.
3. Dynamic ECG [Channel Correct" function, which can correct mistakenly wearing that makes the analysis more accurate.
4.Lorenz and Demix analysis function, which can analyze more faster, more accurately. Single medical case can be completely analyzed in 10 min, which can reduce the physician`s work.
5.ST can be displayed in many kinds of form, which ensures that analyzing ST- Trends Diagram comprehensively, observing the whole or partial ST variety to analyze the specific area of myocardial ischemia.
6.Atrial fibrillation function can be recognized automatically and can distinguish atrial fibrillation case, give advice and generate analysis report .
7.Unique Cardiac Fatigue Index function, which can judge index of Cardiac Fatigue .High-risk groups can be found and early intervention treatment can be taken by the index, which can effectively judge the heart age and predict SCD (Sudden Cardiac Death).
8. P-wave analysis function, which can check cardiac arrhythmia (such as AVB).
9.According to the requirement of patients, options can be selected freely while printing report, which can save physician `s time
10. ECG can be printed by various forms according to the user`s requirement.
11.Pacemaker analysis function, which can analyze different pacemakers(such as AAI,VVI,DDD).
12.The comprehensive analysis system of stand-alone version with network version ,users can freely select any model.
13.Wire and wireless simultaneously transfer mode ,which reduce complicated performance.
14. Dynamic ECG and static ECG analysis system ,which reduced complex operations.
15. Time Domain and Frequency Domain function on HRV module can reflect the moderation effect of sympathetic and parasympathetic to the heart rate.
16.HRT function can predict myocardial infarction which has clinical value.
17.ST function which can check the exact time and length of myocardial ischemia in 24 hours.
