为改良苏打碱化盐渍土,发展畜牧业,1978年本所筛选出星星草,并建立人工草场7510亩,在大安县推广28,000亩.星星草系禾本科碱茅属多年生疏丛型草,适应性强,喜湿润,在-36℃时仍能安全越冬;在含盐量达0.85～0.97%pH值达10.4、碱化度79.3%的土壤上仍能正常发育生长;营养成分高,适口性强.灌溉条件下植草的关键技术是整平土壤,平作条播行距15cm,播深1～2cm,播量7～8公斤/亩;垅作行距60cm,播量减半,播后灌水压盐催苗,产草量166～269公斤/亩.早作地则起垅播种,最佳播期为7月初,产草量144公斤/亩,植草地土壤pH值、总盐量、总碱度和碱化度均明显下降,有改良效果.
In order to improve soda alkalization saline soil, the development of animal husbandry, in 1978 the Institute screened Star grass, and the establishment of artificial grassland 7510 acres, 28000 acres in the promotion of Da’an County. Star grass Department Gramineae Carambola perennial bush type grass, Adaptable, hi moist, still safe to win -36 ℃ winter; salt content of 0.85 ~ 0.97% of the pH value of 10.4, 79.3% alkalinity of the soil can still grow normally; high nutrient content, palatability Strong. The key technology of grass planting under irrigation is flattening the soil, flat for 15 days sowing, sowing depth 1 ~ 2cm, sowing 7 ~ 8 kg / acre; 垅 for row spacing 60cm, sowing half, after sowing irrigation pressure salt Seedlings, grass yield 166 ~ 269 kg / acre. As early as the ground is sowing sowing, the best sowing date early in July, grass yield 144 kg / mu, grassland soil pH, total salt, total alkalinity And alkalinity were significantly decreased, with improved results.
