“小麦若要好,穗多、粒多、籽粒饱”,一语指出了对小麦栽培主攻目标的要求,形成亩有效穗,每穗粒数,和粒重是产量结构三要素的看法,以三者的乘积表示出具体的亩产数。除此,一般认为这种结构式并无其它用处,因为它是收获期的产物,对生育期应该怎么办起不到指导作用,但是仔细考虑一下,这种结构式并不完全是数学的需要,而是客规规律的一种表现,表面的模式隐藏着事物的本质,需要进行一行考察。
“If wheat is good, spikes, grain, grain full”, the phrase pointed out the requirements of the main goal of wheat cultivation, the formation of acres of panicles, grains per panicle, and grain weight is the output structure of the three elements of the view to three The product of the exponents shows the specific yield per mu. In addition, this structure is generally considered of no other use, because it is the harvest of the product, the growth period should not play a guiding role, but after careful consideration, this structure is not entirely mathematical needs, and It is a manifestation of the rules of the custom. The superficial pattern hides the essence of things and needs to be inspected by one party.
