摘要
为了研究微量元素肥料对大姜的生育性状及产量的影响,并探索最佳的施肥水平,在安丘大姜上安排了锌、硼、铁3微量元素"3414"试验(3个肥料因素、4个施肥量水平、14个试验小区)。试验结果表明:大姜增施Zn、B、Fe微量元素肥料对其生育性状有不同程度促进影响,同时产量也有不同程度增加,增幅达0.5%~15.6%。通过回归方程分析,最佳施肥量为40.1 kg/hm^2硫酸锌,25.4 kg/hm2硼砂,600.8 kg/hm^2硫酸亚铁,产量可达84851 kg/hm^2。最佳施肥处理每公顷增加产量5988.5 kg,增产7.6%,每公顷增加产值11977元,投入产出比为1:27.64,可获得最佳经济效益。
To study the influence of trace element fertilizer on growth characters and yield of ginger,andexplore the optimal fertilization level,the authors carried out a＂3414＂test（three fertilizer factors,i.e.,zinc,boron,and iron,four fertilization levels,fourteen plots） of trace element fertilizer on Anqiu ginger.The resultsshowed that the application of Zn,B,Fe trace element fertilizer had different promoting effects on the growth ofginger,and the yield also increased by 0.5%-15.6%.Through regression equation analysis,the authors foundthat the optimum fertilizer amount of per hectare of zinc sulfate was 40.1 kg,borax was 25.4 kg and ferroussulfate was 600.8 kg,and the yield reached 84851 kg/hm^2.Under the optimum fertilization,the yield perhectare increased by 5988.5 kg and 7.6%,the output value per hectare increased by RMB 11977,and theinput-output ratio was about 1：27.64,and the economic benefit was the best.
