目前短生期的豆科绿肥作物已纳入高强度耕作系统中以及高产栽培也留下大量的残留物,这些残留物既可作燃料,也可压施入土作绿肥.作物残茬和豆科绿肥作物可能会影响氮肥的施用效果.本试验着重探讨田菁绿肥和麦秆对施用尿素的稻田氨挥发的影响,室内研究采用压力室技术.
The current short-lived leguminous green manure crops have been integrated into intensive tillage systems and high-yielding crops have also left significant amounts of residue that can be used as fuel or pressed into soil for green manure. Crop residues and legumes Green manure crops may affect the application of nitrogen fertilizer.This experiment focused on the effects of green manure and straw on the ammonia volatilization of rice paddy applying urea, indoor study using pressure chamber technology.
