摘要： 本文研究了不同施肥水平及种植密度对茄子单株和群体效应的影响，结果表明：单株产量随着密度的增加而减少。密度对群体产量的影响与施肥水平有关。在低肥时，密度应小，高肥时可适当提高密度，品种才能获得高产稳产。随着密度的逐步降低，个体补偿效应和群体补偿效应下降，施肥水平越高，补偿效应下降越明显。

Abstract: The effect on single plant and population efficiency of different fertilization levels and population structure on egg plant was studied in this article. The results showed: With the increase of plant density, yield of per plant reduced. Effect on population yield of density was related with fertilization level. Low fertility need low density and high fertility may raise density, the variety will get stable and highest yield. With the increase of plant density, supplement effect of single plant and population decreased. And the highest level of fertilization, the lowest supplement effect decreased.
