摘要
日光温室辣椒施肥指标体系试验结果表明:建议施肥平均单产49 704.0 kg/hm2,产值为323 080.5元/hm2,施肥产投比为41.4︰1;配方施肥平均产量44 551.5 kg/hm2,产值286 717.5元/hm2,施肥产投比69.0︰1。说明氮、磷、钾肥配合施用,辣椒生长和增产效益明显,以达到以产量定施肥量,指导温室辣椒大面积生产的目的。
The experimental results of fertilization indices system for pepper in greenhouse showed that the average yield with proposed fertilization was 49 704.0 kg/hm2, the value of output was 323 080.5 yuan/hm2 and the ratio of output to input of the fertilization was 41,4 ： 1, The average yield with fotTnula fertilization was 44 551.5 kg/hm2, the value of output was 286 717.5 yuan/hm2 and the ratio of output to input of the fertilization was 69.0 ： 1. It shows that the combined application of nitrogen, phosphorus and potassium fertilizers produces a significant effect on the growth and yield increase of the pepper. It provide an basis for achieving the objective of fixing fertilization for expected yield and guiding large-area production of greenhouse pepper.
