Synergistic and sustainable impact of reducing nitrogen fertilizer on growth, yield, and quality of ramie (<i>Boehmeria nivea</i> L.)

Ramie (Boehmeria nivea L.) is China’s unique environmentally friendly cash crop. To protect the environment more strictly and develop sustainably, planting process will reduce input of fertilizer (nitrogen fertilizer). The effect reduced nitrogen on yield quality ramie still under systematic investigation. Taking fiber variety ‘H5’ as target, 4 N application rates 100% (N 390 kg/hm2), 85%, 70%, 55% were set, with no control (marked N100, N85, N70, N55, CK), to study effects reduction yield, uptake utilization, soil fertility. results showed that total production first harvest raw accumulation a trend rising then falling decrease application, output secondary tertiary decreased N85 treatment was highest. Compared N70 can improve n agronomic partial productivity, index. Nitrogen content organic matter, available phosphorus, potassium in ramie, difference between N100 not significant. be by 15% production.
