谷子的产量主要受每南穗数、每穗粒数和单穗粒重等因素的影响。谷子定苗以后,穗数基本是固定的。但何时追施氮肥,以提高穗粒数和粒重是很重要的问题。内蒙古农业科学院土肥所谷子吸收氮素试验的结果,认为谷子在孕穗期至开花期,全植株所吸氮量
The yield of millet is mainly affected by factors such as the number of panicles per panicle, the number of grains per panicle and the grain weight per ear. Millet Dingmiao, the number of spikes is basically fixed. However, when topdressing nitrogen fertilizer to improve grain number and grain weight is a very important issue. Inner Mongolia Academy of Agricultural Sciences Soil Fertilizer Valley nitrogen absorption test results that the billet in the booting stage to the flowering stage, the whole plant nitrogen uptake
