The leaf WUE of millet was increased when root cutting in seedling stage,and only the treatment of I2D of maize increased the leaf WUE; The biomass WUE of millet and maize were increased excepting the root cutting treatments of "TM" and "sl"; At the 80% field capacity, when the root was cutted more seriously and more later,the seed yield WUE of millet were dropped; While at the 50% field capacity, the seed yield WUE of millet was increased when the root cutting is moderate in prophase,and have no reduction of output or increase the production at the same time ,while the benefit of saving water didnt evidently at the later stage root cutting.

苗期伤根处理能够提高谷子叶片WUE，而玉米伤根后仅I2D处理的单叶WUE高于对照；除TM和sl处理外，伤根处理提高了谷子和玉米生物量WUE；在土壤含水量为80%田间持水量时，随着伤根程度的加剧和伤根时间的后移，谷子子粒产量WUE下降，伤根不利于谷子WUE的提高；而在50%田间持水量时，前期伤根量适度的处理在不减产甚至增产的情况下还有助于作物子粒产量WUE的提高，而后期伤根的节水效果并不明显。

The results reveal that under the conditions of the third-class sites in the Southern Fujian mountain areas,the suitable planting density is 1250～1798 trees/hm 2 for building eucalyptus short-cycle industrial raw material forests; and adopting the present density to conduct afforestation may culture the best-selling dimension lumber with higher growth and may obtain better economic benefits.

通过对 7年生巨尾桉不同造林密度生长量、生物量分析，结合目标培育径阶所确定的理论适宜株数的研究，结果表明，在闽南山地Ⅲ级立地条件下，营造桉树短周期工业原料林适宜造林密度为 1 2 5 0～ 1 798株·hm-2 ，采用该密度造林不但可以培育市场畅销的规格材且生长量较高，可取得较好的经济效益

Laboratory incubation experiments were conducted to evaluate the toxicity of cadmium, lead, and zinc in the forms of acetates and chlorides to microbial biomass carbon, biomass nitrogen, and biomass phosphorus in a red soil.

In this study, we take severely soil eroded land, ban forest (as the control I ecosystem after planting Pinus massoniana and baned) and a mixed forest of Cunninghamia Lanceolata plantation and Pinus massoniana (as the control II ecosystem after planting a mixed forest of Cunninghamia Lanceolata plantation and Pinus massoniana and taking engineering restoration measurement)for study.

本文以未治理的侵蚀地作为对照，以在侵蚀地上营造马尾松并封禁管理以及通过工程措施后种植杉木—马尾松混交林为研究对象，通过野外观测和实验室分析，研究了不同恢复措施对土壤结构、土壤化学性质、群落生物量、植物养分、生物多样性的影响。

The addition of Cd,Pb,and Zn in the form of acetate salts demonstrated a considerably greater biocidal effect on soil microbial biomass, because of higher solubility of acetate salts.

以醋酸盐形式加入土壤中的Cd、Pb和Zn对土壤微生物生物量比氯化物有更大的毒性，可能与其较高的溶解度有关。

And, in about half of the fifty, biomass and carbon storage also increased.
