The pot experiment was carried out to study the effect of different organic acids, EDTA, citric acid, oxalic acid and malic acid, on mobilization of Cu in soil and Cu uptake by Leersia hexandra Swartz.
文章采用盆栽试验研究了EDTA、柠檬酸、草酸和酒石酸对土壤中Cu的活化和李氏禾吸收Cu的影响。

The results indicated that the concentration of Cu in the soil is 220.16 mgkg^(-1) contrast to the CK 500.31 mgkg^(-1) significantly decrease when the concentration of EDTA in the soil is 2 mmolkg^(-1) that explains EDTA treatment significantly decreased soluble Cu content in soil because of translating into Cu of water distill floating on the surface of soil and most accumulating around root. Contemporary, application of EDTA to the soil significantly enhanced mobilization of Cu in soil and increased Cu uptake in shoot of Leersia hexandra Swartz., the highest concentration in the leaves 336.54 mgkg^(-1) is 4 times higher compared with the ck 80.34 mgkg^(-1). However, citric acid, oxalic acid and malic acid inhibited mobilization of Cu and less significantly affected shoot Cu accumulation.
结果表明，当向土壤中施加质量摩尔浓度为2mmolkg^(-1)的EDTA时，土壤中Cu质量分数为220.16mgkg^(-1)与空白土壤中500.31mgkg^(-1)相比明显减少，说明EDTA可以极显著的降低土壤中的铜质量分数，使其转化成水提取态的Cu浮于土壤表面，并大部分聚集在根部周围，同时向土壤中施加EDTA不但促进了对Cu的活化而且显著提高了李氏禾对Cu的吸收，叶中最高质量分数达到336.54mgkg^(-1)是对照中80.34mgkg^(-1)的四倍；而柠檬酸、草酸和酒石酸则抑制了Cu的活化，但对李氏禾地上部分的Cu质量分数影响不大。

In vegetation cluster survey, Leersia hexandra Sw. are found hard to survive over 20cm of water in depth which indicated that water level is critical influence in growth and decline of aquatic plants. Different allocation in water depth and partition measures is useful in aquatic plant management.
植群调查中，李氏禾较不易生长於水深超过20公分的区位，水池之水位深度对水生植物之生长与种间消长，占有重要之影响力，规划时可利用不同水深配置搭配堆置物隔离措作为水生植物管理之用。

In the 2-year field experiments, host plant preference and dispersal of the rice water weevil adults of the 1st generation emerged from the 1st cropping season rice were measured on newly transplanted plants of different species and/or growth stage. The weevil preferred significantly to barnyardgrass over Leersia herxandr and Cyperus difformis L with rice at the least, while the age of the plant did not affect such preference. But mean size of feeding scar in on younger plants were larger than in older plants.
在田间自由选择条件下，一代稻水象甲成虫对稗草的选择性显著高于对水稻的选择；稻水象甲对不同生育期的稗草、水稻的选择没有显著影响；对李氏禾和莎草的选择高于水稻，低于稗草；较幼嫩的植物上的取食斑总长度、取食斑平均长度比较老的植物的要长。
