不同施肥方式和用量对夏谷产量的影响

Effects of Different Fertilization Methods and Application Rates on Yield of Summer Millet

通过比较不同底肥追肥量、不同追肥形式处理下的夏谷产量,确定适宜的谷田施肥量和形式,以达到夏谷田减肥增效的目的。以谷子品种汇华金米为材料,设置不同底肥处理(复合肥225,375,525 kg/hm^(2))和追肥处理(基施尿素150、225和300 kg/hm^(2),或叶面喷施蛋白质肥、氨基酸肥),谷子成熟后测定不同施肥处理下的籽粒产量。结果表明,225 kg/hm^(2)的复合肥底肥配合氨基酸叶面肥追肥的谷子产量最高,为5505 kg/hm^(2),525 kg/hm^(2)的复合肥底肥配合300 kg/hm^(2)尿素追肥处理的谷子产量最低,为3765 kg/hm^(2)。从底肥用量上,复合肥用量越高谷子产量越低,225 kg/hm^(2)时产量最高。从追施肥形式上,叶面喷施肥比基施尿素平均增产420~780 kg/hm^(2),氨基酸叶面肥表现最佳,其次是蛋白质叶面肥。对底肥和追肥对产量的影响进行方差分析,结果表明,二者的独立作用极显著,交互作用不显著。

By comparing the yield of millet with different amount of base fertilizer and different forms of topdressing,the appropriate amount and form of fertilizer application in the field of millet were determined,so as to achieve the purpose of reducing weight and increasing efficiency in the field of millet in summer.In the experiment,Huihuajinmi was used as the material,which was treated with different basal fertilizer(compound fertilizer:225,375 and 525 kg/hm^(2))and top dressing(basal urea:150,225 and 300 kg/hm^(2),or protein fertilizer or amino acid fertilizer on the surface of leaves).The seed yield of different fertilizer treatments was measured after ripening.The study shows that the compound fertilizer base fertilizer of 225 kg/hm^(2) combined with amino acid foliar topdressing had the highest millet yield,which was 5505 kg/hm^(2),and the compound fertilizer base fertilizer of 525 kg/hm^(2) combined with 300 kg/hm^(2) urea topdressing had the lowest millet yield,which was 3765 kg/hm^(2).In terms of the amount of base fertilizer,the higher the amount of compound fertilizer,the lower the yield of millet,and the highest yield was at 225 kg/hm^(2).In terms of topdressing fertilization,foliar spray fertilization increased the yield by 420-780 kg/hm^(2) on average than basal urea application.Amino acid foliar fertilizer performed best,followed by protein foliar fertilizer.Analysis of variance was carried out on the influence of base fertilizer and top dressing on yield,and the independent effects of the two were extremely significant,but the interaction was not significant.
