一、热量资源对农业生产的重要意义热量是农业生产中最重要的自然资源之一。作物在一定的温度条件下才能生长发育,并累积到一定的数量才能完成其生命周期。热量还对作物的种类分布、品种类型、产量高低、耕作制度的形成以及引种等,起着依存和制约作用。另外,世界上特定的植物类型,生长在特定的温度范围内,一些气候学家和地理学家,常用温度这个基本的环境因素作为重要指标,进行气候分类,其结果与植物的分布基本一致。因此,对热量条件进行分析,掌握其变化规律,为因地制宜的发展农、林、牧业生产提供依据。
First, the importance of heat resources on agricultural production Heat is one of the most important natural resources in agricultural production. Crops in a certain temperature conditions to growth and development, and accumulated to a certain amount to complete its life cycle. Heat also plays a role of dependence and restriction on the distribution of crops, the types of cultivars, the level of yield, the formation of farming systems, and the introduction. In addition, the world’s specific plant species, growth in a specific temperature range, some climatologists and geographers, the common temperature of the basic environmental factors as an important indicator of climate classification, the results and the distribution of plants is basically the same. Therefore, the analysis of heat conditions, to grasp the changes in law, in order to provide suitable basis for the development of agriculture, forestry and animal husbandry.
