1、作物群体与植物群落是两个不同的概念。2、水稻一生有三个基本矛盾:作物与环境的矛盾、个体与群体的矛盾、营养生长与生殖生长的矛盾。3、恰当发挥分蘖的作用,力争穗数、粒数和粒重三者的均衡发展,才对生产有利。4、关于肥力与密度的关系,作者归结为苗数曲线与穗数曲线,并阐明了它们的基本特性。就苗数而言,瘦田宜稀,肥田也宜稀,前者苗稀而穗亦稀,主要依靠主穗;后者苗稀而穗密,分蘖穗的比重大,甚至依靠分蘖。5、伸缩性是农业科学上的一个重要概念。6、在苗数、穗数、叶面积指数等方面,应根据“从少原则”,或采取“中间偏低”的标准。7、物质基础的创造和运用值得充分重视。8、应根据长相来进行水稻田间管理,而不应仅仅根据叶色变化。
1, crop groups and plant communities are two different concepts. There are three basic contradictions in rice’s life: the contradiction between crop and environment, the contradiction between individual and group, and the contradiction between vegetative and reproductive growth. 3, properly play the role of tillering, and strive to balance the number of spikes, grain number and weight of the three, it is beneficial to the production. 4, on the relationship between fertility and density, the author attributed to the curve of the number of spikes and spikes, and clarify their basic characteristics. In terms of seedlings, thin field should be thin, fat field should be thin, the former sparse seedling and spike are also mainly rely on the main spike; the latter sparse seedling and spike, the proportion of tillering spike, and even rely on tillering. Scalability is an important concept in agricultural science. 6, in the number of seedlings, the number of spikes, leaf area index, etc., should be based on “from the principle of less”, or to “lower middle” standard. 7, the creation and application of material foundation deserves full attention. 8, should be based on looks for paddy field management, and should not be based solely on leaf color changes.
