不同管理模式对生姜产量和养分效率的影响

摘要

为了建立适合山东鲁中地区生姜高产高效栽培的技术体系，通过大田试验，研究了不同管理模式对生姜产量、养分效率及土壤硝酸盐的影响。4个管理模式分别为农民习惯模式、高产高效模式、再高产模式和再高产高效模式，其中农民习惯模式按当地农民常规种植进行，高产高效、再高产和再高产高效模式分别为设置一定增产增效目标下各种管理措施的优化组合。结果为：与农民习惯相比，高产高效、再高产和再高产高效3种模式均显著提高了生姜的产量和氮肥的养分效率，其中产量分别提高11.85%、25.75%和23.34%，氮肥养分效率分别提高47.94%、11.24%和33.14%。再高产模式下产量最高，高产高效模式下氮肥养分效率最高。%In order to establish high-yield and high-efficient cultivation technology for ginger in the central region of Shandong Province, the effects of different manage-ment modes on yield of ginger, nutrient efficiency and soil nitrate were carried out by field experiment. Four management modes were farmer convention mode, high yield and high efficiency mode, super high yield mode and super high yield and high efficiency mode, in which farmer convention mode was local farmers ’ conven-tional cropping methods, the other three management modes were optimized combi-nations of al management measures under a certain goal of increasing yield and efficiency. The results were as fol ows: ginger yield and nitrogen fertilizer efficiency under such three optimized management measures combinations as high yield and high efficiency mode, super high yield mode and super high yield and high efficien-cy mode were al higher than these of farmer convention mode, moreover, com-pared with farmer convention mode, the yield increased by 11.85%, 25.75% and 23.34%, respectively, and nitrogen fertilizer efficiency increased by 47.94%, 11.24%and 33.14%, respectively. Thereinto, the yield under super high yield mode were the greatest,and nitrogen fertilizer efficiency under high yield and high efficiency mode was the highest.
