| 摘 要： | 通过2a田间定位试验,研究渭北旱塬地区夏闲期插播并翻压不同豆科绿肥(长武怀豆、大豆和绿豆,夏休闲为对照)和施氮量(0、108、135、162 kg·hm-2)对冬小麦生长及养分吸收的影响.结果表明:与休闲相比,连续2 a夏闲期种植并翻压豆科绿肥不但能显著提高冬小麦分蘖数、总茎数、产量、植株氮磷钾养分质量分数和吸收量,而且还能提高小麦单位面积穗数.夏季休闲时,连续2a不施氮肥与施用氮肥(108、135、162kg·hm-2)相比,冬小麦产量显著降低.然而,夏闲期种植并翻压长武怀豆和大豆时,连续2 a不施氮肥与施用氮肥(108、135、162 kg·hm-2)相比,冬小麦并没有明显减产；此外,施氮量108、135和162 kg·hm-2处理间小麦产量没有显著差异. |

| Abstract: | Two years field experiments were undertaken in Weibei area to investigate the effect of leguminous green manure(Huai bean,soybean,mungbean and summer fallow as CK) during summer fallow period and nitrogen fertilizer rate(N0,0 kg·hm-2;N108,108 kg·hm-2;N135,135 kg·hm-2 and N162,162 kg·hm-2) on winter wheat growth and nutrients uptake.The results showed that two years incorporation of leguminous green manure during summer fallow period not only increased winter wheat tiller numbers,total shoot numbers,yield,N,P,K concentration and uptake,compared with summer fallow(CK),but also had greater wheat spike numbers.For summer fallow(CK),compared to N108,N135 and N162 treatment,wheat yield significantly reduced in N0.treatment.However,when Huai bean and soybean was incorporated into soil,similar yield were obtained for in all nitrogen treatments. |
