通过对测土配方施肥项目取得的海量棉农抽样调查数据进行汇总整理,了解新疆棉田施肥现状。新疆棉田有机肥单位面积用量为12 256.43 kg·hm-2,区域差异明显,南疆棉田施有机肥较为普遍,而北疆棉田很少施用有机肥。新疆棉田化肥单位面积施用量为462.90 kg·hm-2,N:P2O5:K2O=1:0.58:0.13,南北疆区域差异明显。新疆棉田化肥单位面积施用量呈逐年递增态势,其中钾肥单位面积施用量增长尤为迅速。
Based on the survey data of massive cotton farmers obtained from the project of soil testing and formula fertilization, the fertilization status of cotton fields in Xinjiang was studied. The unit area of organic fertilizer in cotton field in Xinjiang was 12 256.43 kg · hm-2, with obvious regional differences. The application of organic manure was more common in cotton fields in southern Xinjiang, while the organic fertilizers in northern cotton fields were rarely used. The unit area of chemical fertilizer in cotton field in Xinjiang was 462.90 kg · hm-2, N: P2O5: K2O was 1: 0.58: 0.13, and the difference was significant in the northern and southern Xinjiang. The unit area of chemical fertilizer in cotton field in Xinjiang showed an increasing trend year by year, especially the unit area of potassium fertilizer increased rapidly.
