作物的生长冗余和生命体的节约原则

The Uninteresting Growth of Crops and Economical Principle of Living Beings

整枝对果农来说是提高产量的根本栽培措施之一,很少思考为什么要这么做。近年来关于棉花有无必要去营养枝在棉花栽培界存在分歧[1]。但是,棉铃大量脱落的现象熟为人知。水稻、小麦等禾谷类作物高产栽培时需要控制分蘖数和叶面积指数。有时农作物遭到昆虫的取食反会增产。所有这些现象给人以作物具有生长冗余之感性认识。然而,遗憾的是对这一早被认识,普遍存在而且于农业生产上应用悠久并具有重要意义的现象缺乏必要的理性思考。盛承发根据自己的研究,从生存与进化的角度对这一普遍现象的本质进行了深刻的理性探索,提出并赋于'生长冗余'(growth tediousness)概念特定的科学内涵,对于指导农业生产具有重要意义。但是从分子生物学和生物化学角度来考察作物。

Sheng's concept of crop growth tediousness, namely uninteresting growth may be defined as various expanded developmental situations of living systems at different levels (individual, population or community), resulting in the departure from the biosystems steady-states by which men can benefit most. This definition has coordinated the essential concepts of 'growth tediousness' with economical principle of living beings. Three aspects in relation to the study of growth tediousness and two points which must be considered before using the concept of 'growth tediousness' to guide agricultural activities are discussed.
