野生沙打旺的引种试验研究

Experiment on Introduction of Wild Astraganus Adsutgens on Loess Hillyland

野生沙打旺是栽培沙打旺的野生生态类型，引种结果表明：野生沙打旺在年平均气温５℃、７℃、１２．９℃的地区均能开花结果，其产草量和产籽量则随温度的提高而增加。为解决生产上所需种子，可以在温度高的地区建立种子繁殖基地。野生沙打旺适于与禾本科牧草共生，可用以建立产草量高的人工混合草地。

Wild Astraganus adsurtgens is wild ecotype of cultural Astraganus adurgens.The resultof introdction shows:wild Astraganus adsurgens can get flowers and seeds on the areas which themean annual temperature are 5.0℃、7.0℃. and 12.9℃,The temperature is higher,The seed yieldand grass yield is higher.For getting more seeds,the seed propagation base should be set up in hightemperature area. Wild Astraganus adsurgens can symbiosis with grass on artifical grass land,thenthe higher grass yield can be get.
