埃里温的研究人员发现,机械式的摆动(例如微风引起的摆动)能促进农作物生长。他们曾在专门的温室里用荷兰石竹进行试验。在第一个温室里,石竹经受连续不断的方向固定的空气流的作用,在第二个温室里,石竹经受脉冲式的方向不同的风,使石竹在两个相互垂直的平面中摆动;在第三个温室里,空气是静止的。试验条件都相同。结果,第一个温室里石竹的花要比对照温室里石竹的花开得稍早;第二个温室里的人造风是从四面八方吹来的,这个温室里的石竹 Yerevan researchers found that mechanical swinging (such as breeze-induced swings) can promote crop growth. They have been tested with dianthus in a dedicated greenhouse. In the first greenhouse, Dianthus was subjected to a continuous stream of fixed, directed air flow. In the second greenhouse, Dianthus was subjected to pulsating winds of different orientations to swing Dianthus in two mutually perpendicular planes; In the third greenhouse, the air is still. The test conditions are the same. As a result, the flowers of Dianthus in the first greenhouse were slightly earlier than the flowers of Dianthus in the control greenhouse; the artificial wind in the second greenhouse was blown from all directions,
