植物的生活过程中,以遗传潜力为基础,不断地进行着物质、能量、形态结构和信息的转化。这种转化过程随时都受自然条件的影响,对作物来说,还要受到栽培条件的影响。这两种影响因素称为环境条件。在植物生长发育过程中,扣除植物的呼吸作用,脱落、分泌等消耗外,还进行着有机物、化学能和负熵的净积累,最终表现为比种子放大了许多倍的作物物质、能量和负熵的积累量。其中直接被人利用的部分为经济产量。一般所说的作物产量即指经济产量。
Plant life, based on the genetic potential, continue to carry out the material, energy, morphological structure and information conversion. This conversion process is subject to natural conditions at any time, and for crops, it is also affected by the cultivation conditions. These two factors are called environmental conditions. In the process of plant growth and development, the net accumulation of organic matter, chemical energy and negative entropy is deducted from the consumption of plants such as respiration, shedding and secretion. Eventually the crop material, energy, and negative Entropy accumulation. The portion directly utilized is economic output. The so-called crop yield refers to the economic output.
