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 a technical system suitable for high yielding and high efficient cultivation of ginger in Lusaka, Shandong Province, field experiments were conducted to study the effects of different management modes on ginger yield, nutrient efficiency and soil nitrate. The four management modes are farmers habit mode, high yield and high efficiency mode, high yield mode and then high yield and high efficiency model. Among them, peasant habit mode is planted by local peasants, and high yield and high efficiency, high yield and high yield and high efficiency model respectively set a yield increase Effective combination of various management measures under the target. The results showed that compared with farmers’ habits, the three modes of high yield and high yield, high yield and high yield and high efficiency significantly increased the yield of ginger and the nutrient efficiency of nitrogen fertilizer, the yield increased by 11.85%, 25.75% and 23.34%, respectively. The nitrogen fertilizer efficiency Increased by 47.94%, 11.24% and 33.14% respectively. Under the high-yield mode, the yield is the highest, and the high-yield and high-efficiency mode has the highest nitrogen nutrient efficiency.
