Abstract

Abstract:

To investigate the effects of reducing irrigation and chemical fertilizers on eggplant nitrogen absorption and utilization efficiency in a facility vegetable field in black soil region, we analyzed the effects of regular irrigation and chemical fertilizers (CK), 80% regular chemical fertilizers+ regular irrigation, and regular chemical fertilizers+ 80% regular irrigation, on nitrogen absorption and utilization efficiency in eggplant. The results showed that: compared with that of CK, the effect of reducing chemical fertilizer on eggplant yield was not significant (P>0.05),while the eggplant yield in reducing irrigation treatment was significantly decreased by 12.79% (P<0.05). Compared with that of CK, the dry matter of eggplant treated with reducing irrigation and reducing chemical fertilizers was decreased by 15.13% and 6.45%, respectively, but the difference was not significant (P>0.05). There was no significant difference in nitrogen uptake among the three treatments. Compared with that of CK, nitrogen utilization efficiency (NUPE) and nitrogen uptake efficiency (NUE) were increased and nitrogen partial factor productivity (NPFP) was significantly increased by 36.94% in reducing chemical fertilizer treatment. Therefore, in the production of eggplant in greenhouse, the amount of nitrogen fertilizer application can be reduced appropriately, which can not only improve the nitrogen utilization efficiency, stabilize the yield and quality, but also save the nutrient resources and reduce the risk of nitrogen leaching.

Key words: reducing irrigation, reducing chemical fertilizers, eggplant in facility vegetable field, nitrogen uptake, nitrogen utilization efficiency
