摘要
试验通过调查不同用量纳米碳溶胶对玉米植株株高、茎粗及产量的影响,研究施用纳米碳溶胶对玉米的增产效果。结果表明:施入纳米碳溶胶的玉米产量均高于不施溶胶处理。其中,溶胶施入量150 L/hm2时,玉米产量最高,为15 659.3 kg/hm2,比对照(13 068.0 kg/hm2)高2 591.3 kg/hm2,增产19.8%;施入纳米碳溶胶可促进玉米植株生长,其株高和茎粗值均高于不施溶胶处理,溶胶施入量为150 L/hm2时玉米植株长势最好;施入纳米碳溶胶玉米的穗长、行粒数及百粒重均高于不施溶胶处理,其中以150 L/hm2处理的表现最好。综上,施入纳米碳溶胶可促进玉米植株生长、提高产量,溶胶的最佳施入量为150 L/hm2。
The yield-increasing effect of nano-carbon sol application on maize was assessed by using plant height, stem diameter and yield as evaluation indicators. The results showed that： the maize treated with different dosages of nano-carbon sol had higher yield compared to the maize without nano-carbon sol treatment; the highest yield（15 659.3 kg/hm^2） was obtained when the maize was treated with 150 L/hm^2 of nano-carbon sol, which was 2 591.3 kg/hm^2 higher than that of CK（13 068.0 kg/hm^2）, indicating that the yield was increased by 19.5%; the application of nano-carbon sol promoted the growth of maize, higher plant height and stem diameter were observed in the nano-carbon sol treated maize compared with CK, and the best growth was obtained when the maize was treated with 150 L/hm^2 of nano-carbon sol; the maize treated with different dosages of nano-carbon sol had higher ear length, grain number and 100 grain weight than CK, and the best performance in these indicators was observed when the application dosage of nano-carbon sol was 150 L/hm^2. In summary,the application of nano-carbon sol can promote growth and increase yield of maize,and the optimum application dosage was150 L/hm^2.
