试论农业工程中的力学问题及主要研究方向

PRIMARY DISCUSSION TO MECHANICS PHENOMENA AND ITS STUDY TENDENCY LIED IN AGRICULTURAL ENGINEERING

综述了农业工程中所存在的主要力学问题或现象,如:应力与植物的生长、种子损伤与激活、土壤粒子(泥沙)在雨水和江河中的流动、农作物体内水分、矿质元素和光合产物的运输、农作物种植、农产品运输和土壤耕作过程中所存在的力学问题或现象,并在概述了相关研究现状的同时,着重探讨了今后农业生物力学研究的主要方向,强调了加强生物力学研究的重要性.

Some primary mechanics phenomena lied in agriculture and bioengineering are comprehensively dissussed, which contain environmental stress integrated with plant growth and development, seed injury and living, soil flowing in rain or river, water, mineral and production of photosynthesis transporting in body of plants, crop planting and soil cultivating and so on. Meanwhile, the study progress up to now of bio-mechanics has been summarized. Furthermore, the tendency of the study from now on has also been disussed, and the importance to enforce the mechanics study lied in agricultural engineering is stressed.
