【摘要】 １９９２ 年～１９９５ 年，在渭北旱塬对冬小麦陕 ２２９ 进行了不同施肥水平条件下干物质累积和水分利用效率研究。结果表明，在一定的施肥范围内，小麦陕２２９ 对土壤储水的利用程度和干物质累积随着施肥量的增加而提高。通过合理施肥可提高旱地小麦的水分利用效率。更多还原

【Abstract】 The study on the effect of different levels of fertilizer supply on dry matter accumulation and water use efficiency of wheat Shaan 229 was carried out in dryland from 1992～1995. The result showed that under definite fertilizer supply, the soil water utilization degree and dry matter accumulation increased with the fertilizer supply rising. The water use efficiency of wheat could be raised by rational fertilizer supply in dryland.更多还原
