| 摘 要： | 在一定范围内,谷子产量和降水量呈正相关,比值为0.91︰1.00,即生产0.91kg谷子籽粒就需要1mm的降水或灌溉水。降水过多和干旱对谷子生长、生产均有抑制作用,甚至减产,尤其在灌浆期表现更为明显。

| Abstract: | To a certain extent, foxtail millet yield was positively correlated with precipitation, the ratio of these was 0.91︰ 1.00. That is to say per 0.91 kg millet grain yield may need to 1 mm of precipitation or irrigation water. Excessive precipitation and drought on millet growth, inhibit the yield or output, particularly in the grain-filling stage performance became more apparent. |
