生态学是研究生物和环境之间相互关系规律性的科学。从现代生态学观点来看,植物、动物、微生物、无机界(水、土、气、热、光、地形等)、甚至人类社会的发展,都要受生态学规律的约束,当然栽培的植物也不例外。生态条件的综合作用制约着农作物,也制约着农业生产技术。水稻育秧,这一生产环节并不是孤立的,它被放到大自然中,也必然有一个与其周围的生态环境相适应的问题。反映在现实生产中,即是不同的气候条件,不同的耕作、施肥制度,不同的水利、土壤、品种、杂草、地形条件,不同的栽培管理水平,要求具备不同形态和生理素质的秧苗,才能在大面积生产上获得预期的结果。
Ecology is a science that studies the regularity of the relationship between an organism and the environment. From the point of view of modern ecology, the development of plants, animals, microorganisms, the inorganic world (water, soil, air, heat, light, topography, etc.) and even human society must be governed by ecological laws. Of course, cultivated plants No exception. The combined effect of ecological conditions restricts the crops, but also restricts the agricultural production technology. Rice seedling, the production link is not isolated, it is put into nature, but also must have a compatible with the ecological environment around it. This is reflected in the actual production, that is, different climatic conditions, different farming and fertilization systems, different water conservancy, soil, breeds, weeds, topographical conditions and different cultivation and management levels require seedlings with different morphological and physiological qualities, In order to achieve the desired result in large-scale production.
