- 摘要:
- 为研究玉米品种龙单42的最适种植密度和最佳施肥量，采用二因素完全随机区组试验，研究了不同种植密度和施肥水平对龙单42农艺性状及产量的影响。结果表明：龙单42的最佳密度为61 538 株·hm-2，施肥水平为尿素300 kg·hm-2、磷酸二铵300 kg·hm-2、氯化钾100 kg·hm-2，此条件下产量最高，为13 269.25 kg·hm-2。
- 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·hm-2，diammonium phosphate 300 kg·hm-2，potassium chloride 100 kg·hm-2.The highest yield was 13 269.25 kg·hm-2。
