In normal moisture treatment under the single planting mode, root excision reduced the spike weight and aboveground biomass of wheat as well as the kernel yield by19.20%. 小麦单播湿润处理下,断根降低了小麦穗重和地上部生物量,且籽粒产量降低了19.2%。
No matter monocultures or mixed-cultures, the amplitude of the soil water contents during the root signaling period of the root-excised winter wheat ( secondary root cutting) are wider than that of the without root excision. 不论是单播还是混播,断根处理(去除次生根)的根信号土壤含水量的阈值宽于未断根处理的土壤含水量。
