水稻产量是由每亩总穗数、每穗总粒数、结实率及千粒重四要素构成的。四要素之间是互相关联、互相影响的矛盾运动过程,当它们发展到一定的水平时,每亩总穗数增加,每穗总粒数会减少,每穗总粒数增加,结实率会下降;穗数与粒数、粒数与结实率呈负相关;结实率与千粒重呈正相关,一般结实率良好千粒重亦会增加,结实不良千粒重有减轻的趋势,因此,研究它们之间的内部矛盾性,抓住主要矛盾,在栽培技术上采取相应的有效措施,就有可能获得更高的产量。
Rice yield is the total number of spikes per acre, the total number of grains per panicle, seed setting rate and the weight of four components of grain weight. The four elements are interrelated and influence each other’s contradictory movement process. When they reach a certain level, the total number of spike per acre will increase, the total number of spike per panicle will decrease, the total number of spike per panicle will increase and the rate of seed setting will decrease ; Spike number and grain number, grain number and seed setting rate was negatively correlated; seed setting rate and 1000-grain weight was positively correlated, the general seed setting rate of good 1000-grain weight will also increase, the solid bad grain weight tends to reduce, therefore, to study the internal contradictions between them , Seize the major contradictions in the cultivation techniques to take appropriate and effective measures, it is possible to obtain higher yields.
