摘　　要：为做大做强生姜产业,减少肥料流失和控制面源污染,同时更好地提高生姜产量,探索了不同肥力地块生姜高产的合理种植密度以及高肥力不同种植密度下的合理施肥量。设置高、中、低不同地力条件下种植密度对莱芜生姜生长及产量影响的单因素试验,以及种植密度(667 m^(2)种植量A_(1):4000株;A_(2):5000株;A_(3):6000株)与施肥量(667 m^(2)施肥量B_(1):N 40 kg、P_(2)O_(5)7.5 kg、K_(2)O 55 kg;B_(2):N 42 kg、P_(2)O_(5)7.5 kg、K_(2)O 57 kg;B_(3):N 44 kg、P_(2)O_(5)7.5 kg、K_(2)O 59 kg)二因素互作对生姜产量影响的效果比较试验。结果表明:在不同地力条件下,高肥力地块每667 m^(2)种植3000~6000株,中等肥力地块每667 m^(2)种植4000~7000株,低肥力地块每667 m^(2)种植5000~8000株的范围内,生姜株高均呈现随种植密度的增加而增加的趋势,而分枝数、667 m^(2)产量则随种植密度的增加均呈现先增加后减少的趋势;合理的种植密度有利于提高单株根茎质量,获得高产,生产上建议高肥力地块每667 m^(2)种植5000株左右,中等肥力地块每667 m^(2)种植6000株左右,低肥力地块每667 m^(2)种植7000株左右。高肥力地块上的种植密度与施肥量二因素互作试验结果表明,种植密度、施肥量、种植密度与施肥量互作对小区产量的影响均达极显著差异水平,种植密度以667 m^(2)种植5000株小区产量最高,为321.8 kg,667 m^(2)施肥量为N 42 kg、P_(2)O_(5)7.5 kg、K_(2)O 57 kg时小区平均产量最高,为314.4 kg,以上种植密度与施肥量互作时小区产量最高,为419.2 kg。生产上建议高肥力地块每667 m^(2)施N 42 kg、P_(2)O_(5)7.5 kg、K_(2)O 57 kg,种植5000株左右,选用种姜块质量100 g左右,采用行距60 cm、株距22 cm。In order to make the ginger industry bigger and stronger,reduce fertilizer loss and control nonpoint source pollution,and improve the yield of ginger better at the same time,the reasonable planting density of ginger in different fertility lands and the reasonable fertilization amounts under different planting densities in high-fertility land were explored.A single-factor experiment was conducted on the effects of planting density on the growth and yield of'Laiwu'ginger under different soil fertility conditions,and a comparative experiment with two-factor interaction was conducted on the effects of planting densities(with 4000,5000,6000 plants per 667 m^(2)in treatment A_(1),A_(2),A_(3),respectively)and fertilization amounts(with N,P_(2)O_(5),K_(2)O of 40,7.5,55 kg per 667 m^(2)in B_(1),42,7.5,57 kg per 667 m^(2)in B_(2),44,7.5,59 kg per 667 m^(2)in B_(3),respectively)on the yield of ginger.The results showed that under the conditions of different fertility lands,in the range of 3000-6000 plants per 667 m^(2)in high-fertility land,4000-7000 plants per 667 m^(2)in medium-fertility land and 5000-8000 plants per 667 m^(2)in low-fertility land,the plant height of ginger increased with the increase of planting densities,while the number of branches and yield of 667 m^(2)increased first and then decreased.Reasonable planting densities were convenient to improve the rhizome weight of a single plant and obtain high yield.In production,it was recommended to plant about 5000 plants per 667 m^(2)in high-fertility land,about 6000 plants per 667 m^(2)in medium-fertility land and about 7000 plants per 667 m^(2)in low-fertility land.The results of the experiment on the two-factor interaction of planting density and fertilization amounts showed that the effects of planting density,fertilization amounts,and the interaction of planting density and fertilization amounts on the plot yield reached an extremely significant difference level in high-fertility land.The highest plot yield was 321.8 kg when the planting density was 5000 pla
