Effects of Full-Element Bio-Organic Fertilizer on Growth,Yield,and Rhizosphere Soil Nutrients of Pepper
A field experiment was conducted to evaluate the effects of self-developed full-element bio-organic fertilizer on the growth,yield,and rhizosphere soil nutrients of pepper.Four treatments were designed,including full-element bio-organic fertilizer+conventional fertilizer reduced by 50%(T1),inactivated full-element bio-organic fertilizer+conventional fertilizer reduced by 50%(T2),conventional fertilizer(T3),and no fertilizer(CK).The results showed that T1 significantly increased the plant height,crown width,fruit number per plant,and yield of pepper.T1 had higher pH value,total nitrogen,total phosphorus,total potassium,available nitrogen,available phosphorus,and available potassium in the rhizosphere soil than T3 and CK,and it had higher available phosphorus and available potassium than T2.The disease index of bacterial wilt in T1 was 21.74,which was 10.37,20.19,and 35.48 lower than T2,T3,and CK,respectively.The control effect of T1 reached 56.71%.The above results indicated that whole bio-organic fertilizer promoted the growth to improve the yield and benefit of pepper.Moreover,the fertilizer activated soil nutrients to improve soil fertility and reduced soil-borne diseases.Therefore,the full-element bio-organic fertilizer can be promoted in the pepper fields with continuous cropping obstacles.
