为了研究沙质红壤土中磷肥投入量对中花117花生经济效益的影响,在广西贺州市钟山县钟山镇杨岩村沙质红壤土上开展中花117春花生磷肥最佳用量试验研究。结果表明,沙质红壤土种植中花117花生最佳施P2O5量为60.6 kg/hm2,最佳产量为3 139.9 kg/hm2,与不施磷肥的对照处理比增产花生922.9 kg/hm2,增长41.63%;增加收益为8 876.1元/hm2;产投比达到26.15。
In order to study the impact of the amount of phosphate fertilizer on the economic benefits of Zhonghua 117 peanut in the red sandy loam soil, the optimum amount of phosphate fertilizer for Zhonghua 117 spring peanut was experimented on sandy loam soil in Yangyan Village, Zhongshan Town, Zhongshan City, Hezhou City, Guangxi Province. The results showed that the optimum amount of P2O5 was 60.6 kg / hm2 and the optimum yield was 3 139.9 kg / hm2 in the peanut cultivar Zhonghua 117, which was 9 139.9 kg / hm2 compared with 922.9 kg / hm2 peanut without phosphate fertilizer, an increase of 41.63 %; Increase income is 8 876.1 yuan / hm2; production and investment ratio reached 26.15.
