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 amount were 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.
