我盟的北部有野生黄芪。从1961年开始,我们进行了野生变家种的试验,获得了成功并得到产品。种植面积逐年扩大,现全盟累计面积有2万多亩。起初在春季(4、5月)或秋季(8、9月)播种。但因春季干早,风砂大,地温低,播后种子得不到充足的水份和适宜的温度;秋季地温急剧下降,播下的种子等到来年才发芽。因此,春、秋季播种的黄芪出现出苗不整齐,缺苗严重等现象。后来通过对本地区气候的分析,根据无霜期平均只有120天,年降雨 There is wild Astragalus in the northern part of our Union. Since 1961, we have experimented with wild species and succeeded in getting products. The planting area is expanding year by year, and now the total area of ​​the alliance has more than 20,000 mu.

However, due to the early dry spring, the large sand and low ground temperature, the seed did not receive enough water and suitable temperature after sowing. Therefore, spring and autumn sown Astragalus emergence irregularities, lack of seedlings and so on. Later through the analysis of climate in the region, according to the average frost-free period of only 120 days, annual rainfall
