利用中国农业科学院红壤实验站红壤稻田长期定位试验,于2011年研究了在以无机肥(化肥NPK)与有机肥(M)氮磷钾养分等量条件下,长期有机无机肥配施水稻生育期间杂草种类和生物量变化。结果表明:30a后,早稻和晚稻施肥处理中:PK+ M处理下杂草种类最多,NPK+M处理下杂草种类和优势杂草种类较少,且种类数量稳定,早稻和晚稻杂草种类数量前者比后者分别高出19.7%和9.8%;施肥处理中:两季杂草总生物量NPK+M处理最高,NP+M处理最低,且NPK+M、NK+M、PK+M和CK处理比NP+M处理分别高出31.3%、26.5%、8.3%和5.6%,早稻NPK+M处理杂草总生物量和浮生杂草总生物量最多,NK+M 处理湿生杂草总生物量最多,晚稻NK+M处理杂草总...

Long-term located fertilization test has been conducted to evaluate how fertilization affects the growth and yield of crops particularly rice over 30 years in the Red Soil Field Experimental Station, Chinese Academy of Agricultural Sciences, Qi Yang, China. However, how and why However, how and why fertilization influences the growth of crops in the field particularly in the paddy field has not been assessed. Consequently, an investigation was carried out in a double-rice paddy field to study the species and biomass of weeds found in rice (Oryz...
