摘要

以陕北榆林市榆阳区田区试验结果为基础

对陕北黄土丘陵沟壑区主要小杂粮作物的降水生产潜力进行了研究分析。结果表明

不同小杂粮作物降水生产潜力依次为:谷糜＞黑豆＞绿豆＞荞麦。目前陕北黄土丘陵沟壑区主要小杂粮作物的生产潜力开发度仅为9.78%~19.07%

平均为13.83%

尚有86.17%的生产潜力没有发挥出来。田区试验结果与公式概算具有很好的吻合度

表明所取得的降水生产潜力结果具有可靠性。对照较低的现实生产水平

该结果预示着小杂粮生产的巨大发展前景。

Abstract

Based on the two-year field experiment in Yuyang district of North Shaanxi Province

the rainfall productive potential of minor grain crops in the loess hilly and gully region of North Shaanxi Province is studied systematically. Results show that minor grain crops rank in the descendant order of millet

black soybean

mung bean and buckwheat in terms of the rainfall productive potential. Development degree of the rainfall productive potential in the region is from 9.78% to 19.07%

with an average of 13.83% only. This indicates tremendous prospects of their productive potential exploiting.
