| 中文摘要: |
| 在渭北地区自然降水条件下，采用裂区设计方法，研究了肥力、播期和密度三要素对旱地小麦新品种普冰143产量构成因素及产量的影响。结果表明：普冰143是一个抗旱、抗病、高产、优质，适应旱肥地种植的优良品种；普冰143在三种肥力下，各有最适的播期和密度要求；为了求得既高产又稳产，普冰143施肥应为中肥水平，播期（在乾县北原及同类地区）应在9月24日前后，密度以每667 m2基本苗16万～20万为宜。 |
| 英文摘要: |
| Under the condition of natural precipitation of north Weihe River，the winter wheat variety Pubing143 was used to study the effect of fertilities, sowing date and densities of dryland wheat on its yield and components by split-plot design. The results showed that Pubing143 is a variety of drought and disease resistance, high yield, good quality and high adaptability. It had different optimal sowing date and density requirements in the three types of soil fertility. In order to achieve both high and stable yield, Pubing143 should be planted on the following condition——the medium level of fertilizer，the sowing date in about September 24 (Beiyuan in Qianxian County and similar areas), and the density of 160 000～200 000/667 m2. |
