论文部分内容阅读
本次专业会议于1982年10月27日至11月2日举行。出席代表88人,收到论文报告102篇。 华孟、张蔚榛教授和张君常副教授在大会上分别作了题为“美国西南几州土壤水与植物关系的研究倾向”、“水盐运动数值模拟分析”和“土壤—植物—大气中水分能量运转平衡热力势函数的初探”的专题报告。在大会上宣读的论文有26篇。会议还组织了18篇墙报进行交流,并展出了土壤湿度计、水田渗漏仪、土壤通气仪、土壤坚实度计和野外测试车等。 会议重点检阅了近年来土壤水分研究方面的成果,还交流了有关土壤基本物理性研究的进展:1.应用能量观点来研究土壤水分的保持和运行。初步明确了0.3~15巴范围内的有效水对植物的有效性是不等效的,而且与蒸腾等条件有关。土壤吸力增加,土壤的比水容量(de/ds)下降,毛管传导度亦相应降低。土壤供水容量和强度都会对植物根系吸收土壤的有效
This professional conference was held from October 27 to November 2, 1982. 88 delegates attended the conference, and received 102 papers. Professor Huameng, Professor Zhang Weihen and Professor Zhang Junchang made a speech titled “Research tendency of relationship between soil water and plant in southwestern states of the United States”, “numerical simulation analysis of water and salt movement” and “soil-plant-water moisture energy operation A Preliminary Report on Equilibrium Thermodynamic Potential ”. There are 26 papers presented at the conference. The conference also organized 18 posters to communicate and exhibited soil hygrometers, paddy field leak detectors, soil aerators, soil solidity meters and field test vehicles. The conference reviewed the achievements in recent years on soil moisture research and also exchanged the progress on the basic physical research of soil: 1. Studying the maintenance and operation of soil moisture with energy viewpoint. Preliminary clear that the effective water within the range of 0.3 ~ 15 bar is not equivalent to the effectiveness of the plant, but also with the conditions such as transpiration. Soil suction increased soil specific water capacity (de / ds) decreased capillary conductivity also decreased. Soil water supply capacity and intensity of the plant roots will be effective in absorbing soil
