为实现青贮玉米的高产高效栽培,以青贮玉米品种强盛30为供试材料,设置6个施肥水平,研究并探讨不同施肥模式下青贮玉米的生长指标、叶面积、产量等。结果表明,基肥施尿素187.5 kg/hm~2、磷酸二铵228 kg/hm~2及追肥施水溶肥(35-0-10)315 kg/hm~2;基肥施尿素127.5 kg/hm~2、磷酸二铵228 kg/hm~2、磷酸钾90 kg/hm~2及追肥施尿素282 kg/hm~2;基肥施尿素127.5 kg/hm~2、磷酸二铵228 kg/hm~2、磷酸钾90 kg/hm~2及追肥施尿素402 kg/hm~2 3个处理较其他处理对玉米各个指标值的影响较明显;基肥施尿素187.5 kg/hm~2、磷酸二铵228 kg/hm~2及追肥水溶肥(35-0-10)315 kg/hm~2处理抗倒伏能力最好,其次是基肥施尿素127.5 kg/hm~2、磷酸二铵228 kg/hm~2、磷酸钾90 kg/hm~2及追肥施尿素282 kg/hm~2处理,基肥施尿素127.5 kg/hm~2、磷酸二铵228 kg/hm~2、磷酸钾90 kg/hm~2及追肥施尿素402 kg/hm~2处理相对其他处理抗倒伏性也比较好,基肥施尿素127.5 kg/hm~2、磷酸二铵228 kg/hm~2、磷酸钾90 kg/hm~2及追肥施尿素201 kg/hm~2处理抗倒伏性能最差。
In order to realize high yield and high efficiency cultivation of silage maize, six silage maize varieties were selected as test materials and six fertilization levels were set up to study and explore the growth indexes, leaf area and yield of silage maize under different fertilization modes. The results showed that 187.5 kg / hm2 urea, 228 kg / hm2 diammonium phosphate fertilizer and 315 kg / hm2 urea fertilizer fertilizer were applied to basal fertilizer and 127.5 kg / hm2 urea fertilizer , 228 kg / hm ~ 2 of diammonium phosphate, 90 kg / hm ~ 2 of potassium phosphate and 282 kg / hm ~ 2 of topdressing urea; The effects of 90 kg / hm ~ 2 potassium phosphate and 402 kg / hm ~ 2 urea on top dressing were more significant than those of other treatments on 187, 187 kg / hm2, 228 kg / hm ~ 2 and topdressing water soluble fertilizer (35-0-10) 315 kg / hm ~ 2 were the best, followed by basal fertilizer application of 127.5 kg / hm2 urea, 228 kg / hm2 diammonium phosphate, Potassium 90 kg / hm ~ 2 and topdressing urea 282 kg / hm ~ 2, basal application of urea 127.5 kg / hm ~ 2, diammonium phosphate 228 kg / hm ~ 2, potassium phosphate 90 kg / Urea 402 kg / hm ~ 2 treatment is better than other treatments in lodging resistance, basal urea application 127.5 kg / hm ~ 2, diammonium phosphate 228 kg / hm ~ 2, potassium phosphate 90 kg / hm ~ 201 kg / hm ~ 2 treatment worst lodging resistance.
