| Abstract: |
| In order to explore the impact of different water soluble fertilizers on yield of maize and verify the effects of patented formula fertilizers and its application methods on maize under drip irrigation, the 6 kinds of new type of water soluble fertilizers, which are formulated by urea phosphate(X1), amino acid(X2), Humic acid potassium(X3), water-soluble nano-organic fertilizer(X4), amino acid water soluble fertilizer(X5), half the amount of acid soluble fertilizer containing(X6), patented fertilization(X7) and no fertilizer(X8) were used in the study. The results showed that amino acid, potassium humate can promote maize germination,and the emergence rate of both treatments exceeds 50% in the first week. urea phosphate, amino acid, potassium humate can promote the germination rate of maize under drip irrigation and the germination rate exceeds 90%. Patented formula fertilization has the highest leaf area index LAI, which is significantly higher than other treatments. also patented formula fertilization can promote the growth of maize.The whole plant biomass is: jointing stage X7>X5>X6>X3>X4>X1>X2>X8, flowering period X7>X6>X5>X4>X2>X1>X3>X8, mature X2>X8>X6>X7>X4>X3>X5>X1. The dry matter transfer amount and transfer efficiency of amino acid soluble fertilizer had the highest contribution rate to grain, which was significantly higher than that of the patented formula fertilization, and the contribution rate of dry matter transfer to the grain reached 43.36%. Amino acid-containing water-soluble fertilizer and patented formula fertilization were favorable to the increase of maize yield, which increased by 44.5% and 46.5% respectively compared with the non-fertilizer treatment. |
