【摘要】：借助于中国知网(www.cnki.net),在收集、整理大量文献资料的基础上,从工程、生物、化学、生物培肥和综合五个方面系统梳理和总结了自21世纪以来中国中低产田改造技术的类型、特点及其适用范围。结果表明:包括工程技术和土壤培肥技术等在内的传统技术仍然是目前中国治理各种中低产田的基础技术,新的中低产田改造技术在不断诞生,特别是在生物技术和化学技术领域,中低产田改造逐步由单一技术向多种技术融合转变;今后研究的重点应放在中低产田治和防的平衡问题,增施有机肥与土壤面源污染问题,中低产田改造技术的大范围推广问题和中低产田改造与农村土地综合整治的联动问题。
[Abstract]:With the help of www.cnki.net, on the basis of collecting and sorting out a great deal of literature, from engineering, biology and chemistry, In this paper, the types, characteristics and application scope of the transformation technology of middle and low yield fields in China since the 21st century have been systematically summarized in five aspects of biological fertilization and synthesis. The results show that the traditional technology, including engineering technology and soil fertilization technology, is still the basic technology for controlling all kinds of middle and low yield fields in China at present, and new transformation techniques for middle and low yield fields are constantly coming into being. Especially in the field of biotechnology and chemical technology, the transformation of middle and low yield fields has gradually changed from a single technology to a variety of technologies. In the future, emphasis should be placed on the balance between the treatment and control of the middle and low yield fields, increasing the application of organic fertilizer and soil non-point source pollution, the popularization of the technology for the transformation of the middle and low yield fields and the linkage between the transformation of the middle and low yield fields and the comprehensive regulation of rural land.
