过早或过晚地收获农作物,对产量和品质都会造成一定的影响。收获过早,子粒尚未充分成熟,这样即会降低子粒品质,又会减少粒重,降低产量;相反,则造成子粒脱落在地,减少收成,因此,要做到增产丰收,就必须要掌握各种农作物的最佳的收获期,以防伤镰和落镰,而影响增产。现介绍几种主要作物的最佳收获期及识别方法。谷子:谷子开花时间较长,同一个 Harvesting crops too early or too late can have some impact on yield and quality. Harvest too early, the grain has not yet fully mature, so that will reduce the quality of the grain, but also reduce the grain weight and reduce the output; the opposite, then cause the particles fall to the ground, reduce the harvest, therefore, to achieve yield increase, we must grasp the The best harvest period for the crop species is to prevent sickle and sickle disease and affect yields. The best harvest and identification methods for several major crops are presented. Millet: Millet flowering longer, the same one
