三棱草

稻田三棱草化学防除技术研究

Research on Chemical Control Techniques of Rhizoma Sparganii Weed in the Paddy Field

探讨几种药剂防除直播稻田水三棱草的效果。

The research aimed to study the effects of several herbicides to Juncellus serotinus .

长秆苔草和紧穗三棱草各龄级分株均进行有性生殖，并保持一定量的生殖分配大小，是适应生境的生殖策略权衡的结果。

Furthermore , the more or less of the reproductive allocation was certain and that is the result of reproductive trade-off and the adaptation to their habitats .

地下根茎为芦苇现存碳储量的主要场所，而地上部分是海三棱藨草碳储量的主要场所。

The underground rhizome of P.australis and the aboveground part of S.mariqueter were the main sites of existing carbon storage .

目前，崇明东滩湿地植被群落演替的基本模式为：盐渍藻类群落海三棱藨草群落／藨草群落芦苇群落。

At present , the basic pattern is saline algae community , Scirpus marqueter / Scirpus triqueter community and reed community .

海三棱藨草的密度和单位面积结实枝条数显著大于互花米草。

However , the density and number of flowering tillers per square meter for Spartina alterniflora were significantly lower than those of Scirpus mariqueter .

全年调查结果显示，非水鸟分别占盐渍藻类带、海三棱藨草带／藨草带、芦苇带观察种数的7.25%、31.25%和47.06%，比例逐渐升高，春夏秋冬四季均符合这个规律；

It was 7.25 % in saline algae zone , 31.25 % in Scirpus marqueter / Scirpus triqueter zone and 47.06 % in reed zone ;
