Astragalus adsurgens has developed roots and strong nitrogen fixation ability. It can improve soil structure and improve soil fertility. In the land where Astragalus adsurgens has been planted, the fertilization effect can be maintained for 3 ~ 5 years, and the next crop can increase production by more than 20%. Astragalus adsurgens is an excellent windbreak, sand fixation and soil fixation. It can be planted in windblown sand eroded land, gully erosion, canal embankment slope and other places, which can achieve better water and soil conservation, and maintain the biological characteristics of Astragalus adsurgens. It belongs to medium dry plants and adapt to it., It is strong, well developed and most suitable for growing in sandy loam. It has strong adaptability and developed roots. It is most suitable for growing on sandy loam with pH 6 ~ 8 and has certain salt alkali resistance.

When the salt content in the cultivated layer of 30cm soil is 0.68% ~ 0.7%, the emergence rate of Astragalus adsurgens in the field is 85%. The annual average temperature is 8 ~ 15 ℃, the accumulated temperature of ≥ 0 ℃ is 3600 ~ 5000 ℃, and the annual average temperature is lower than 10 ℃ and the accumulated temperature of ≥ 0 ℃ is 3600 ℃, In areas where the frost free period is less than 150 days, the seeds of Astragalus adsurgens are difficult to mature or only a small number of seeds mature, and the seedlings and adult plants can tolerate - 4 ~ - 3 ℃ low temperature during growth.

Feed value and utilization of Astragalus adsurgens from seedling stage to full flowering stage, carbohydrate content increased from 63% to 79%, nitrogen-free extract (starch, dextrin and sugars, etc.) decreased from 45% to 3%, crude fiber increased from 18% to 37%, and increased to 48% when defoliation after frost. The crude protein content of Astragalus adsurgens in hay was 14% ~ 17%, slightly lower than that of alfalfa.

The crude protein content in young plants was higher than that of aging plants, and the protein content in early flowering stage was 12.29%, It is only lower than that in seedling stage (13.36%), higher than that in vegetative stage (11.2%), budding stage (03%) and defoliation stage after frost (4.51%). The crude protein life in the latter defoliation stage is only 1 / 3 ~ 1 / 2 of that before the full flowering stage. In different growth years, the total content of amino acids is the highest in the first year, with a variation range of about 8% ~ 9.6% in plants reaching the last 2 ~ 7 years, close to grass roots (98%) and lower than that of Ruthenia ruthenica (12.22%)
