玉米是一种高产作物,收获不当可造成8～10%的减产,即每亩要少收100斤左右籽粒,很可惜。科学实验表明,玉米收获早晚对产量和质量影响很大。就山东省而言,各地一般习惯在玉米果穗苞叶发黄,籽粒上部变硬时便开始收获。研究表明,这时的玉米仅处在蜡熟期,还没有完全成熟。此时收获,玉米要减产8～10%,而且品质差,出粉率低。 Corn is a high-yield crop. Improper harvesting can result in a decrease of 8-10%. That is, it is a pity that seeds should be collected at a minimum of 100 pounds per mu. Scientific experiments show that corn yield sooner or later on the yield and quality of great influence. In terms of Shandong Province, the general habit of corn in all parts of the ear yellow leaves, hardened when the upper part of the grain began to harvest. Studies show that the maize at this time only in the waxy period, not fully mature. At this point of harvest, maize to cut 8 to 10%, and poor quality, low rate of flour.
