摘  要：
通过冬小麦—夏玉米轮作下3年6季的田间试验,研究纳米级材料胶结包膜型缓/控释肥料对氮素利用率和硝态氮淋溶损失的影响。结果表明,与普通氮磷钾化肥配施相比,4种纳米级材料胶结包膜型缓/控释肥料提高小麦对氮素的利用率2.802~3.38个百分点,玉米对氮素的利用率1.012~1.63个百分点。在0—80 cm土层,PS、BC208和306处理下土壤硝态氮含量高于普通氮磷钾化肥配施处理,而F208处理低于普通氮磷钾化肥配施处理;在80—160 cm土层,均低于普通氮磷钾化肥配施处理;在接近地下水水位土层(140—160 cm),减少硝态氮1.612~.42 mg/kg。4种纳米级材料胶结包膜型缓/控释肥料损失出土壤-作物系统的氮素比普通氮磷钾化肥配施处理减少2.002~4.90个百分点。结果表明,纳米级材料胶结包膜型缓/控释肥料能有效的提高氮素利用率和减少硝态氮的淋溶损失。

摘  要：
A 3-year and 6-season field experiment involving winter wheat and summer corn rotation was conducted to study the effects of slow/controlled release fertilizers felted and coated by nano-materials on nitrogen recovery and accumulation of NO-3-N.The results showed that for the treatment of slow/controlled release fertilizers felted and coated by nano-materials,N recovery of wheat and corn increased 2.80-23.38 percentage points and 1.01-21.63 percentage points compared with NPK treatment separately.At 0-80 cm in soil profile, NO-3-N concentration of PS,BC208 and 306 treatments were higher than that of NPK treatment,but F208 treatment was lower.At 80-160 cm in soil profile,NO3-N concentration of NPK treatment was the highest.At 140-160cm in soil profile,NO-3-N concentration decreased by 1.61-2.42 mg/kg and N loss decreased by 2.00-24.90 percentage points out of soil-crops system for slow/controlled release fertilizers felted and coated by nanometer materials compared with NPK treatment.The results showed slow/controlled release fertilizers felted and coated by Nano-materials could improve nitrogen recovery and decrease NO-3-N loss effectively.
