| Abstract: In order to effectively reduce the amount of chemical fertilizer used in pepper production, the effects of conventional fertilizer and equal nutrient commercial organic fertilizer replacement proportion of 100%, 1/2 and 2/3 chemical fertilizer on biological properties, economic properties, disease resistance, stress resistance and yield of pepper were studied by taking 'Zhuojiao No.8' as material. The results showed that compared with conventional fertilization, the replacement of equal nutrients organic fertilizer with the appropriate proportion could improve the commercial properties and increase the yield of pepper. When the replacement proportion was 1/2, the growth period of pepper was the most benefi cial, and the plant height, stem diameter, fruit length, pulp thickness and yield increased by 20.34 cm, 0.37 cm, 2.5 cm, 0.047 mm and 67.05%, respectively. It was suggested to popularize and apply in actual production. |
