采用L9(34)正交试验设计方法,以固糜 21 为材料,研究了糜子的种植密度和施肥配比对产量和生物性状的影响,结果表明,在不同的种植密度下,糜子株高、穗长、主穗粒质量、千粒质量、产量都存在差异,并且籽粒产量、生物产量和千籽粒质量受密度影响较大,综合分析,宁南山区旱地糜子在生长周期内应该施N 375 kg/hm2、P2O5 225 kg/hm2、K2O 75 kg/hm2,其中氮肥60%一次性做基肥施入,磷、钾肥全部做基肥施入,糜子的最佳适宜种植密度为60万株/hm2,最佳产量为4 980.3 kg/hm2.

The used L9(34)orthogonal design method,the material is Gu Mi 21,the planting density and fertilizer proportion of millet influence on the yield and the biological traits,the results show that under different planting density,millet plant height,spike length,the main differences between spike grain weight,grain,rice yield,and the grain yield,biological yield and thousand kernel weight are greatly influenced by the density,comprehensive analysis,Ningnan mountain area dryland millet in growth cycle should take N 375 kg/hm2,P205 225 kg/hm2,K20 75 kg/hm2,basal nitrogen 60%one-time do plowing,Phosphorus,Potassium base fertilizer facilities into all,the best suitable for planting millet density of 600 000/hm2, best production in 4980.3 kg/hm2.
