作物从土壤溶液中吸取养分和水分,供其生长的需要。由于降雨、温度以及微生物和植物活动等的影响,都会使土壤溶液中离子浓度时刻发生变化,因此难以掌握其实际状况,增加了土壤溶液中各种养分浓度同作物生长的关系的复杂性。无论从土壤化学角度,还是从土壤作为作物的培养基的角度,再有从农地的环境方面来看,都迫切地期望不断掌握其信息。本文将就土壤溶液与作物生长的关系作一论述。土壤溶液的离子组成示于表1
Crops draw nutrients and moisture from soil solutions for their growing needs. Because of the effects of rainfall, temperature, microorganisms and plant activities, the concentration of ions in the soil solution changes from moment to moment, making it difficult to grasp the actual situation and increasing the complexity of the relationship between various nutrient concentrations in soil solution and crop growth. From the point of view of soil chemistry and from the point of view of soil as a medium for crop production and then from the perspective of the environment of agricultural land, it is eagerly expected to constantly grasp its message. This article will discuss the relationship between soil solution and crop growth. The ionic composition of the soil solution is shown in Table 1
