本文论述了植物栽培生理的特点、任务和研究途径。指出植物栽培生理是一门边缘科学,在内容上介于植物生理与作物栽培之间,在性质上介于基础科学与应用科学之间,在方法上介于实验科学与理论科学之间。它的主要任务是研究作物高产、稳产、优质、低耗的生理基础。研究作物在栽培条件下的生理变化并从中找出用以指导生产实践的原则和理论。根据栽培生理的特殊性,在研究的方式方法上不能完全套用植物生理与作物栽培的老方法,而应根据它的特殊目的和任务来确定其相适应的研究内容和方法。本文提出了从光合性能、群体结构、个体营养、培育壮苗和促进产品器官发达及增产来源与比例等方面有关的测定方法和分析途径。
This article discusses the characteristics, tasks and research approaches of plant physiology. It is pointed out that plant physiology is a marginal science, which lies in the content between plant physiology and crop cultivation, between the basic science and the applied science in nature, and between the experimental science and the theoretical science in the method. Its main task is to study the physiological basis of crop high yield, stable yield, high quality and low consumption. Study crop physiological changes under cultivation conditions and find out the principles and theories used to guide the practice of production. According to the particularity of cultivation physiology, the methods and methods of research can not fully apply the old methods of plant physiology and crop cultivation, but the research contents and methods should be determined according to its special purposes and tasks. In this paper, the methods of determination and analysis of photosynthetic properties, population structure, individual nutrition, nurturing strong seedlings and promoting the development of the organs of the products and the sources and proportions of yield increase are put forward.
