Precision Irrigation Technology Status and Future Development

The stress of crop production, plant protection information for field data to provide a favorable basis. (3) to obtain soil information. The collection of soil information,ugg boots billig, crop growth from the impact of environmental conditions, soil moisture levels and nutritional point of access, to analyze the yield map shows differences in spatial distribution of production,timberland sale, the development of irrigation, fertilization, soil improvement, planting and other farming and distributed localization prescription decisions. Such information because of their spatial and temporal variability can be divided into two categories. ~ Category is relatively stable, low spatial and temporal variability of soil information, such as terrain slope, soil type structure, phosphorus, potassium, SOM, pH and topsoil depth; one for the large spatial and temporal variability of soil information, such as soil moisture and nitrogen content and so on. In addition to their fertilizing,moncler jackets, planting or irrigation operation of basic data is necessary before the measurement and spatial distribution of production, but also need to measure the growth period of sampling necessary in order to timely control inputs. Rapid acquisition of soil moisture content which sensing technology, rapid development in the 2O end of the century. Current measurement technique based on microwave time domain reflectometry soil moisture quickly measuring instrument, experimental studies in water-saving agriculture has been a lot of applications. 4 precision irrigation technology is the future of precision agriculture the inevitable result of modern agricultural development. In recent years, as an important part of precision agriculture, precision irrigation technology has become advanced irrigation technology, water management in agriculture an important part of information technology, agriculture and water resources it is reasonable to improve their crop yields, lower production costs, improve the ecological 61 * environment, excellent irrigation water power 2, 2010 [Article ID] 1002 - 0624 (2010) o2-0o6O-o2 micro-irrigation in the development and application prospect XUE Jin-Hong, Chen Hongfu (Baotou Water Survey & Design Research Hospital, Inner Mongolia Baotou 014020) [Abstract] This paper introduces the status of domestic and international micro-irrigation technology, the technology to China in the field doing research and development and implementation of an objective and realistic detail, and the prospect of the application of this technology prospects. [Key words] micro-irrigation technology; application status; development prospects [CLC] $ 275 [Document code] E1 1.1 micro-irrigation development status of foreign micro-irrigation technology and current status of being in the micro-irrigation, irrigation to appear in the earliest. The first time in 1860 in Germany underground irrigation drain tile test, the results can be planted in poor soil on crop yield doubled. The study of 20 consecutive years. 1920 out of the water flow to achieve a breakthrough. Developed a ceramic tube with a porous, so water along the pipeline into the soil from the hole. In 1923 the Soviet Union and France also conducted a similar experiment, the perforated pipe system, irrigation methods, the main change is the use of groundwater for irrigation. . American Studies in 1934 with a porous canvas tube irrigation. Since 1935, after testing various materials focused on the hole pipe system. According to the tension of soil water flow to determine the soil pipe in the water. The Netherlands, the United Kingdom the first application of this method of irrigation, greenhouse irrigation, flowers and vegetables. After World War II, the plastics industry is developing rapidly. Appeared in a variety of plastic pipe. Because it is easy to perforation and connection, and the price is low, the technical realization of the irrigation system a second breakthrough, as the form used today. To the late 50's, Israel successfully developed a long flow tube emitter. The development of drip irrigation technology has taken an important step. Since the 70s many countries starting to focus on drip irrigation, drip irrigation has been rapid development, access to a wide range of points, becoming the most attractive to the international forefront of academic research areas. Currently less than 2% of world's irrigated land to start using this technology. Of precision irrigation technologies in China developed the work started late, only a small number of research institutes and research and development work in this area, research is still in its infancy,north face outlet, the practical application of results is not satisfactory, therefore, accelerate the development of their own, in line with China's national conditions precision irrigation systems and related measures is imperative. Situation of our country. Research and development system for precision irrigation technologies to promote sustainable agricultural development in China is important. * 62 [
