| 摘 要： | 以辣椒品种好农11为试材,在安徽和县开展田间试验,研究膜下滴灌条件下温室秋延辣椒的养分吸收及分配规律。结果表明,辣椒产量47100kg·hm~(-2),植株地上部干物质累积量8163kg·hm~(-2),收获指数0.70,植株干物质增加最快时期为膨果期,膨果期干物质累积量占整个生育期的33.3%;辣椒整个生育期吸收的养分钾氮磷,氮(N)的吸收量186kg·hm~(-2),磷(P2O5)的吸收量61.0kg·hm~(-2),钾(K2O)的吸收量313kg·hm~(-2),植株吸收的氮磷钾主要分配到果实中,氮磷钾的收获指数分别为0.59、0.78、0.58,膨果期辣椒氮磷钾的吸收量最高,分别占整个生育期的37.6%、28.5%、38.4%;钙镁硼的吸收量钙镁硼,钙(Ca O)的吸收量135kg·hm~(-2),镁(Mg O)的吸收量74.9kg·hm~(-2),硼(B)的吸收量0.13kg·hm~(-2),钙镁硼的收获指数分别为0.08、0.32、0.46,钙镁在叶中的累积量最高,分别占植株吸收总量的79.8%、54.1%,而硼主要分配到果实、叶中,分别占植株吸收总量的46.2%、39.2%,膨果期钙镁硼的吸收量最高,分别占整个生育期的34.6%、33.3%、38.2%。

| Abstract: | Taking pepper variety‘ Haonong No.11’ F1hybrid as experimental material，this paper carried out field trial in He county of Anhui Province，and studied on the nutrients absorption and distribution rule of autumn-winter pepper in greenhouse under mulched drop-irrigation system．The results indicated that the pepper yield reached 47 100 kg·hm-2，the total accumulation of dry matter was 8 163 kg·hm-2，and the harvest index was 0.70．The most rapid dry matter increasing period for plant was at the stage of fruit formation．Its accumulation quantity accounted for 33.3% of the whole growth period．Pepper nutrient absorption during the entire growth period is potash（ K）＞ nitrogen（ N）＞ phosphorus（ P），and the absorption of N，P2O5 and K2O were 186、61.0、313 kg·hm-2，respectively．The absorbent N，P，and K were mainly distributed to fruits，and their harvest indexes were 0.59，0.78，0.58，respectively．The N，P，and K absorptive amountwere the highest in the stage of fruit formation，accounting for 37.6%，28.5%，38.4%，respectively．As for the Ca，Mg，B，their absorptive amount was Ca ＞ Mg ＞ B．The plant absorbed CaO，MgO and B were 135、74.9、0.13kg·hm-2，respectively，and the harvest indexes were 0.08，0.32，0.46，respectively．The highest Ca and Mg accumulation were in leaves，accounting for 79.8% and 54.1%，respectively．B was mainly distributed in fruits and leaves accounting for 46.2%，39.2%，respectively．The Ca，Mg and B absorptive amounts were the highest during the stage of fruit formation accounting for 34.6%，33.3%，38.2% of the whole growth period． |
