biomass increment meaning in English

生物量增长量

Field germination , nodulation status and physical growth parameters of seedlings ( shoot and root length , vigor index , collar diameter , leaf number , fresh and dry weight of shoot and root and total dry biomass increment ) were recorded after three and six months of seed sowing
播种的3和6月后，记录幼苗大田发芽、分枝状况和其他物理生长参数（枝条或根长、活力指数、茎直径、叶片数、分枝或根鲜重和干重、总的生物量干重增长）等。
The quantity of increased leaf efficiency contributed to the aboveground biomass gain after defoliated are different at different irradiance . at the initial stage , the increased leaf efficiency of defoliated plants contributed more to biomass increment of aboveground under higher light level than those under lower irradiance . as the treatment time extended , the contribution to growth of increased leaf efficiency of plants under intermediate light level went beyond those under full irradiancy
( 2 )叶受损的植株叶效率显著高于未受损植株；光照强度越高，植株的叶效率越高；受损植株增加的叶效率在不同光照条件下对生长的贡献大小不同，处理初期，全光照下叶损失植株增加叶效率对地上部分的生物量增加贡献大于中度光照，大于低光照下植株，随处理时间的延长，中度光照下的植株增加叶效率对生长的贡献逐渐超过了全光照下植株。
