谷子籽实产量高低,是由每亩总粒数的多少和千粒重的大小两个因素决定的。每亩总粒数是由每亩穗数,分支小穗群数(谷码子),小穗数等组成,而千粒重则是由饱满籽粒和秕粒重量组成的。这些相互之间有内在连系的因子,究竟那个是决定产量高低的主导因素?张家口专区农科所 Millet seed production level, is the total number of grains per acre thousand grain size and size of two factors. The total grain number per acre consists of the number of spikes per acre, the number of branch spikelets (grains), the number of spikelets, etc. The thousand-grain weight consists of plump grains and kernel weight. These factors are inter-related to each other, what is the dominant factor that determines the level of output? Zhangjiakou Prefecture Agricultural Science Institute
