李森科院士的植物阶段发育理论,正确地揭露了植物生长与发育的本质及其相互联系,因而使人们已能控制植物的生长和发育,主动地进行作物生产。大家都知道,为了放牧而种植的牧草,要达到高额的收获,就必须创造条件,使牧草能旺盛地生长而具有较少的发育;而以籽实为主要经济收益的作物,只有在繁旺的生长和充分的发育条件下,方能达到高额产量。因为作物的收获物是生长和发育在一定程度上结合的结果,人们只有对植物的生长发育了解得愈清 The theory of plant stage development of academicians of LI Senke correctly exposed the nature and interrelation of plant growth and development, thus enabling people to control the growth and development of plants and take the initiative to carry out crop production. As we all know, forage grasses that are planted for grazing need to create the conditions for vigorous growth and less development of the forage to be harvested, while the forage crops as the main economic benefit are only exuberant The growth and full development conditions, can only achieve high yields. Because the harvest of the crop is the result of the combination of growth and development to some extent, one can only understand the growth and development of the plant
