(一) 地质工作为农业服务的内容很广,笔者认为可概括为五个方面。 1.进行土壤和农业地质背景研究。土壤是农作物生长的“基地”,是各种成土因素(如母岩、生物、气候、地形、时间和人类活动等)综合作用的产物。它的基本特性是其肥力。地质作用对土壤的形成和变化有着决定性影响。地表岩石是形成土壤的物质基础(即所谓成土“母质”),它在很大
(1) The content of geological work for agriculture is very wide. I think it can be summarized in five aspects. 1. Conduct soil and agricultural geological background research. Soil is the “base” for the growth of crops and is the result of a combination of various soil-forming factors (such as parent rock, biology, climate, topography, time, and human activities). Its basic characteristic is its fertility. Geological effects have a decisive influence on the formation and change of soil. Surface rock is the material basis for the formation of soil (the so-called soil “master”), which is very large
