Abstract

Abstract:

The objective of this study is to investigate the effects of two kinds of organic fertilizer replacing partial chemical fertilizer on plant development and yield of pepper and soil nutrients, and to explore the feasibility of organic fertilizer replacing partial chemical fertilizer for reducing fertilizer consumption and increasing efficiency, thus providing theoretical basis for scientific fertilization of pepper. The results showed that organic fertilizer replacing partial chemical fertilizer did not affect the agronomic characters of the pepper plants. Compared with conventional fertilization, the yield of pepper was increased by 0.33%-4.66% under bio-organic fertilizer replacing partial chemical fertilizer treatments; The yield of pepper reduced by 0.66%-5.91% under cow and sheep manure replacing partial chemical fertilizer treatments, but the difference was not significant. Short-term organic fertilizer instead of chemical fertilizer could increase the content of soil organic matter, but the content of total nitrogen, available phosphorus,and available potassium did not change regularly. In summary, it is feasible to replace chemical fertilizer with bio-organic fertilizer, and it will not reduce the yield of pepper, and it has a better effect that replacing 50% chemical fertilizer with bio-organic fertilizer.

Key words: organic fertilizer replacing chemical fertilizer, pepper, yield, soil nutrients
