摘要
对谷子新品种豫谷15进行了不同种植密度和氮、磷、钾不同施肥量配比试验,研究不同密度及肥料配合效果。结果表明,不同的施肥量与种植密度处理下,产量呈现出一定的相关性。在安阳市柏庄镇区域生产中该谷子品种的最佳种植密度为67.5万株/hm2,最佳施肥搭配组合为纯N 375 kg/hm2,P2O575 kg/hm2,K2O 75 kg/hm2。不同种植密度对豫谷15植物学性状和产量构成因素的影响较大,氮、磷、钾不同施肥量级处理对豫谷15产量构成因素和植物学性状有不同的影响。
The-tests of different planting densities and nitrogen, phosphorus, potassium and different fertilizer levels ratio of new variety millet Yugu 15 were conducted, for studing combined effect of density and fertilizer on Yugu 15. The results indicaded that the yield that with different amount of fertilizer and planting density treatment had a certain correlation. The optimum planting density of Yugu 15 in regional production in Bozhuang Town of Anyang City was 675 000 plants/hm2, the best fertilizer combination was the pure N 375 kg/hm2, P205 75 kg/hm2, K20 75 kg/hm2. The effect of different planting densities on tile Yugu 15 botanical traits and yield component factors was obvious, and nitrogen, phosphorus and potassium fertilization middleweight handling have different effects on production factors and botanical characters of Yugu 15.
