Effects of Biofilm Fertilizer on Growth,Yield and Quality of Green Pepper
In order to research the effects of different concentrations of biological bacterial fertilizer on the growth,yield and quality of green pepper in greenhouse,the dilution concentration of 200(X200),400(X400),600(X600),800(X800)were set up for the study of Alstonia pepper and Cayenne pepper.The indicators of morphology,yield,photosynthetic pigment content,and quality of peppers were measured during the mature period.The results show that the biological bacterial fertilizer has a positive effect on the growth,yield and quality of green pepper compared with the clear water control group(CK).Among them,X200 treatment promoted the best effect of the two kinds of green pepper,the determination of height,chlorophyll a,chlorophyll b,total chlorophyll content,carotenoid content of Alstonia pepper is up to 77.33 cm,3.23 mg/L,2.50 mg/L,5.04 mg/L and 0.84 mg/L,and that of Cayenne pepper is up to 76.68 cm,5.03 mg/L,1.65 mg/L,7.80 mg/L and 1.34 mg/L.Compared with CK,the yield,pericarp thickness and vitamin C content of Alstonia pepper increased by 176.84%,56.84%and 38.10%respectively,and those of Cayenne pepper increased by 103.04%,21.40%and 94.74%respectively.Moreover,the crude fiber content of both kinds of green peppers was decreased with four diluted concentrations of biofertilizer.The conclusion is that X200 treatment has a significant effect on promoting the growth,yield and fruit quality of green pepper.
