| 摘 要： | 在半干旱地区对春小麦新品系A005-1进行了适宜密度和施肥量的研究。结果表明,种植密度和施肥水平对春小麦A005-1的产量均有重要影响,二者间存在较强的互作效应。综合考虑成本等因素,当种植密度为375万株/hm2、磷酸二铵施量为96 kg/hm2时,春小麦新品系A005-1的产量最高,为1 985.69 kg/hm2。 |

| Abstract: | The suitable plant density and fertilizer quantity of new spring wheat variety A005-1 was studied in the semi-arid area. The results showed that the plant density and fertilizer quantity have important influence on the yield of new variety A005-1, and the interaction between plant density and fertilizer is still obvious. Considering the cost and other factors, when the plant density is 3 750 thousand plants/hm2, （NH4）2HPO4 is 96 kg/hm2, the new spring wheat variety A005-1 has the highest yield, it is 1 985.69 kg/hm2. |
