披硷草(Elgmius、excelsns)属高产牧草,抗寒性能较强,幼苗在北方可耐-40℃低温,适于降水300—400mm地区生长,耐盐硷,可在含盐0.7%左右地带生长,生长期为128天。1987年5月至1989年5月,利用三年时间进行试验及观测。试验地植被为草甸草原类,根茎丛生禾草组。原植被群落为:虎尾草加隐子草和杂类草。草场干草产量20千克/亩,植被复盖度30%。土壤为盐硷草甸土,pH值9—10。该区无霜期为130—140天,年积温2858℃,年降水量360mm Elsium (excelsns) is a high-yielding pasture with strong cold-resistant ability. The seedlings can tolerate low temperature of -40 ° C in the north, suitable for growing in the area of ​​300-400 mm of precipitation, and tolerant to salt and alkali, and can grow at a salt content of about 0.7% , The growth period of 128 days. May 1987 to May 1989, the use of three years of testing and observation. The experimental vegetation is a meadow grassland and a group of rhizome tufts. The original vegetation community as follows: Chloris virgata Canada plus grass and miscellaneous grass. Pasture hay yield 20 kg / mu, vegetation cover 30%. Soil is saline alkali meadow soil, pH 9-10. The area frost-free period of 130-140 days, annual accumulated temperature 2858 ℃, the annual precipitation 360mm
