摘要

黄土丘陵区旱坡地栽培芦笋，土壤侵蚀量较空白地（CK

）减少93.5%～96.2%

较谷子地（CK

）降低91.4%～93.1%;平均每hm~2芦笋年纯收入4055.70元，分别是陕北坡旱地传统经济作物马铃薯、大葱、向日葵、芝麻及籽瓜等纯收入的2.1倍、1.4倍、5.0倍2.4倍和2.1倍。以上试验品种均能适应当地生态条件，其中以UC157在坡旱地表现最好，根系发达，生长茂盛，抗旱性较强，栽后4～5年平均产量达7731kg/hm

为MaryWashington（CK）的1.6倍。凋萎叶较对照减少38%

一、二级笋占91.3%

是极适宜早坡地栽培的优良品种。并结合旱坡地的特点研究提出了栽培管理技术措施要点。

Abstract

Planting Asparagus on steep slope land of more than 300 with deepening level ditches in loess hilly region，the quantity of soil erosion could be decreased by 93. 5%^} 96. 2 0

o than cori-trolling field (with no plants planted in it)，and by 91. 4%-93. 1%than millet field. The aver-age net income was 4055. 7 Yuan per hmy yearly，which was much higher than that of local traditional economical plants. The experiments indecate that Uc157 is the superior cultivar of Asparagus in the region in view of its well-developed roots and growing luxuriantly. Its yield reached 7731kg/hm= the fourth year after planting.which was 1. 6 times higher than control variety of Mary Washington. Besides，the cultivar of Uc157 performed dry resistant character. The ratio of withered leaves was 38%.lower than that of the control variety. The first and second grade of Asparugjus shoots was as high as 91. 3%.
