| Abstract: | In order to research the optimal plant density and fertilizer amount on the maize varieties Longdan 42, randomized complete block design of two factors was used with the varieties Longdan 42 as materials, the effects of different plant density and fertilizer level on the yield and agronomic characters. The results showed that the best density of Longdan 42 was 61 538 plant·hm-2 , the optimum fertilization amount was that urea 300 kg-hm2,diammonium phosphate 300 kg·hm-2, potassium chloride 100 kg·hm-2. The highest yield was 13 269.25 kg·hm-2. |
