几年来,我们在研究高产小麦生物学产量时观察到郑引一号小麦,穗头部分与茎杆部分的干物质重量大致相等。而穗头中籽粒重占百分之七十五到八十。颖壳及穗轴占百分之二十到二十五。从许多高产田块的统计得知小麦地上部干物质积累总量有百分之二十五到四十构成麦粒,一般情况,干物质总量常与产量成正相关,那么如何能使已形成的干物质更多的向穗部运转,构成麦粒,这在提高产量上是个重要问题。
In the past few years, we observed the yield of wheat in high-yield wheat Zheng-1 wheat, the head part of the dry matter and stem part of the weight is roughly equal. The grains in the heads account for 75 to 80 percent. Husk and cob occupy twenty to twenty percent. Statistics from many high-yield plots show that 25% to 40% of the total dry matter accumulation in wheat shoots constitutes wheat grains. In general, the total amount of dry matter is often positively correlated with the yield, so how can it be formed? The more dry matter that runs to the spikes constitutes wheat grains, which is an important issue in increasing yields.
