Abstract: To explore the best combination of millet which nitrogen, phosphorus, boron and zinc concentration, it can provide a theoretical reference to optimize cultivation techniques and improve yield. The local red broomcorn millet was used as the studied material, and the effect of different gradient zinc and boron treatment on yield, grain filling rate, dry matter mobility and transport rate of broomcorn millet was studied through randomized complete block design. The results showed that, B2 treatment had the highest yield; it was 5300.80 kg/hm2. We also found that supply B2 or Zn2 alone was good than B plus with Zn, it showed an increase in yield compared with contrast were 14.63% and 11.52%, respectively; after 14 days after blossom, the grain filling reached a maximum, B2 treatment had prominent effect compared with the other treatment; the dry matter mobile rate in leaf was higher than stem, the transport rate in stem was higher than leaf; B2 treatment had the most predominant effect in stem and leaf transport rate, it was 41.55% and 22.23%; millet supplied with the B was good than Zn treatment in dry matter output, grain contribution rate and yield during the whole period. Adding boron and zinc fertilizer significantly increased the output rate and dry material transfer rate, in favor of broomcorn millet yield increase, especially the boron fertilizer was the best.
