摘　　要：采用田间试验方法,研究了保护地辣椒完全空白(T1)、农民习惯施肥(T2)、等量控释氮肥和磷钾肥(T3)、80%控释氮肥和等量磷钾肥(T4)、80%控释氮肥和80%磷钾肥(T5)等不同施肥方式和施肥量对辣椒产量、植株养分含量、干物质积累量及品质的影响。结果表明:与农民习惯性施肥相比,T3处理产量最高,比T2增产12.3%,T4、T5处理产量并未显著性降低。在定植后40d,各处理辣椒植株N、P、K含量达到最高,T3处理干物质累积量和氮磷钾累积量较高。T4处理氮磷钾累积量比T2处理高。T2、T3、T4处理辣椒维生素C含量差异性不显著,各处理间辣椒可溶性糖含量变化不大。T3、T4、T5处理辣椒硝酸盐含量均显著低于T2处理(P<0.05)。综合考虑,在农民习惯性施肥基础上施用80%控释氮肥和等量的磷钾肥可以保证较高的产量和较好的果实品质。The effects of different treatments of fertilizer on the yield,quality,plant nutrient content and dry matter accumulation in vegetable greenhouse were studied,by the method of field test.There were five treatments： completely blank（T1）,habitual N management of the local farmers（T2）,and the same amount of controlled release nitrogen fertilizer,P and K（T3）,80% controlled release nitrogen fertilizer and 100% P and K（T4）,80% controlled-release fertilizer and 80% P and K（T5） on pepper yield.The results showed that T3 treatment had the highest yield,increased 12.3% compared with T2.Compared with T2 and T3,T5 treatment did not significantly reduce yield.In the 40 days after planting,the pepper N,P,K content reached maximum in all the treatment.T3 treatment had the highest dry matter accumulation and N,P,K accumulation,and the N,P,K accumulation of T4 treatment was higher than T2 treatment.The green pepper vitamin C content difference was not significant among T2,T3 and T4.The green pepper soluble sugar content changed little among all the treatment.T3,T4,T5 treatment green pepper nitrate levels were significantly lower than the T2 treatment（P〈0.05）.Considering the farmers habitual fertilizer application,80% controlled release nitrogen and the same amount of P,K could guarantee a higher yield and better fruit quality.
