小麦只有适时收获，才能使籽粒充分成熟，饱满度高，发芽率高发芽势才强。如果收获过早，籽粒不能充分成熟，直接影响千粒重和籽粒内的化学成份，使产量和品质下降。同时，也不耐贮藏。若收获过迟，小麦在田间易受损失，同样影响品质，降低产量。小麦成熟期可分为腊熟期和完熟
Only timely harvest of wheat, in order to fully mature grain, plump, germination rate is high. If premature harvest, the grain can not fully mature, a direct impact on grain weight and grain chemical composition, the yield and quality decline. At the same time, they are not resistant to storage. If the harvest is too late, wheat is vulnerable to losses in the field, also affecting quality and reducing production. Wheat maturity can be divided into wax maturity and maturity
