Study on the relationship between soil fertility properties and species diversity in grass layer showed that the main factor affecting species diversity was soil PH, then was the soil total phosphorus.

4对防护林草本层物种多样性指数与土壤肥力因子的关系研究表明：影响草本层物种多样性的主要因子是土壤PH 值，其次是土壤全磷含量。

According to the gallus colony stimulating factor(colony-stimulating factor,CSF)cDNA sequences published by GenBank,a pairs of specific primer was designed,the local dorking was injected 100 μg/mL ConA,total RNA was extracted from feeding 24 hours lymphocyte from spleen,then dorking colony stimulating factorcDNA fragment was cloned by RT-PCR technology.

根据GenBank中报道的红原锦鸡集落刺激因子(Colony-stimulatingfactor，CSF)cDNA序列，利用Primer Premier5.0软件设计一对特异性引物，对本地肉鸡注射100μg/mL ConA试剂，饲养24 h后，取脾脏提取淋巴细胞总RNA，利用RT-PCR技术克隆集落刺激因子的cDNA片段。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.
