Effects of Foliar Spraying Potassium Humate or 6-BA on Agronomic Characters and Quality of Pepper
It was verified whether potassium humate could achieve the effect of 6-BA in some functions by spraying continuously different concentrations of potassium humate or 6-benzylaminopurine(6-BA)on pepper.A total of 6 treatments were designed to investigate the agronomic and quality characteristics of pepper.The results showed that the spraying of potassium humate or 6-BA had the same function in stimulating the growth of pepper,increasing the yield and improving quality of pepper,but the spraying of potassium humate at an appropriate concentrationhad a more obvious effect on reducing the nitrate content compared with 6-BA,while the spraying of 6-BA at an appropriate concentration had a better effect on increasing fruit length and weight than humic acid.The spraying 6-BA with 400 times dilution or potassium humate with 10000 times dilution both significantly increased the soluble sugar content of pepper fruits.According to various indexes,potassium humate diluted by 10000 times was the best,6-BA diluted by 600 times was the best.
