Effects of Foliar Fertilizer Containing Biostimulants on Photosynthetic Characteristics,Yield and Quality Indexes of Maize
Dika 653 was selected as experimental material to study the effects of foliar fertilizer containing different biostimulants such as Mairunon which containing organic matter,Maifuli which containing amino acid,Overflow which containing humic acid,Haoxiufeng which containing seaweed extract and humic acid on the photosynthetic characteristics,yield and quality were studied. The results showed that the four kinds of foliar fertilizers significantly increased the net-photosynthetic rate of leaves,and Haoxiufeng performed best. Compared with the control,the number of grains per row of Mairunang and Maifuli increased significantly,and the yield increased 11.6% and 8.8% respective-ly;The number of grains per row and 100-grain weight of Haoxiufeng treatment increased significantly,and the yield increased by 13.4%. The four kinds of foliar fertilizers had no significant impact on the bulk density and energy value. Mairunang,Maifuli and Overflow reduced the content of DON,while Haoxiufeng reduced the content of DON and ZEN. Based on the above results,the two biostimulants contained in Ha-oxiufeng which containing two kinds of biostimulants played a synergistic role in improvement of photosynthetic index,yield and quality of maize.
