The main factor influencing variation in RWL was water regimes, relating to timing and intensity of water stress.

影响RWL变化的主要因素是水分，与水分胁迫的时间和强度有关。

Under different water regimes, spike number per plant (SNP), effective spikelet per spike (ESPS) and peduncle length (PLE) contribute a lot to the stable grain yield.

不同水分条件下，植株稳产性主要受单株穗数、有效小穗数及穗下节长的影响；

Water regimes exhibited no effects on bacterial-feeding nematodes, fungal-feeding nematodes, microbial biomass C and microbial biomass N during rice tillering and heading stages.

不同水分管理方式在水稻分蘖期、抽穗期对食细菌线虫数量、食真菌线虫数量、微生物量C和微生物量N没有影响。

This is where recognition of the fundamental ecological functions of wetlands as regulators of water regimes comes into its own.
