收割小麦,一般均认为在黄熟期(蜡熟期)为适期,这时植株的形态标志是田间植株叶片大部枯黄,茎秆也大部变黄,籽粒已由凝蜡状变硬。过去认为,这时千粒重达最大值,蜡熟期收割,产量高、品质好。 1980年,我们在取样调查中发现乳熟末期黄熟初期收割,千粒重最高(见附表)。这一时期的特点是籽实尚带绿色,顶部叶片
Harvesting wheat, generally considered in the ripening stage (wax maturity) is the appropriate period, then the shape of the plant is marked with yellow leaves most plants in the field, most of the stalks turn yellow, the grain has been hardened by the wax. In the past, at this time, the grain weighed to a maximum value, the waxy stage was harvested, the yield was high and the quality was good. In 1980, we found in the sampling survey early millet ripening yellow ripening, the highest grain weight (see table). The characteristic of this period is that the seeds are still green with the top leaves
