对东北盐化草甸小獐茅群落地上生产结构和生物量形成规律进行的初步研究表明，群落生产结构呈下繁型。地上生物量以Ｙ＝ａ＋ｂｘ＋ｃｘ￣２形式增长，峰值出现在８月。相对增长速率（ＲＧＲ）在抽穗前（５月上旬～６月上旬）最高，为０．１２５１ｇ／ｇ／天；绝对增长速率呈双峰型，峰值分别出现在抽穗前期和果后营养期（７月上旬～８月上旬）。 Preliminary studies on the aboveground production structure and biomass formation of the Salina delavayi community in northeastern saline-alkali meadow showed that the community production structure was undergoing extensive type. Aboveground biomass grows in the form of Y = a + bx + cx ~ 2, the peak appears in August. The relative growth rate (RGR) was the highest before heading (from early May to early June), reaching 0.1251 g / g / day. The absolute growth rate was bimodal with peaks at the early heading and post-vegetative periods respectively Early month ~ early August).
