罗城县早稻“3414”肥料效应田间试验研究

摘要

为探讨罗城县西部乡镇农业生态区域的作物施肥效应,进行洪积潴育沙泥田早稻＂3414＂肥效试验。根据试验结果,获得肥料效应函数方程,由此数学模型得出理论氮、磷、钾最佳经济施肥量,其中N11.19kg/667m2,P2O54.42kg/667m2,K2O 8.00kg/667m2,最佳经济产量为547.46kg/667m2。结合当地农业生产实际,氮、磷、钾推荐量分别为N11.04～11.21kg/667m2、P2O54.25～4.44kg/667m2、K2O 8.00～8.10kg/667m2。%In order to explore fertilizer effectiveness in western towns of Luocheng, an experiment on ＂3414＂fertilizer effectiveness of early-flee was conducted in paddy-field. Based on the experimental results, a mathematics model was deduced to obtain best fertilization amounts with N 11.19kg/667m2, P2O5 4.42kg/667m：, K2O 8.00kg/667m2 . Relevantly, the highest yield will be 547.45kg/667m2. Accord- ing to real condition, the recommended fertilization will be N 11.04 -11.21kg/667m2,P2O5 4.25 4.44kg/667m2,K2O 8.00-8.10kg/667m2.
