沼液施用量对鲜食糯玉米生长及产量的影响

采用盆栽试验,研究了沼液施用量对鲜食糯玉米植株性状及产量的影响。结果表明：随着沼液施用量的增加,鲜食糯玉米的株高、茎粗、穗位高、穗长和产量随施用量的增加而增加,沼液施用量为8000kg/667m₂^(处理4)时达到最高,沼液施用量为9000kg/667m₂^(处理5)表现为降低,说明适宜用量的沼液能够促进玉米的生长发育,过量施用沼液则表现为一定抑制作用。综合分析可以确定鲜食糯玉米生产中沼液施用量应控制在为8000kg/667m₂^为宜。

Effect of biogas slurry application rate on growth and yield of fresh waxy corn

Pot experiment was conducted to study the effect of biogas slurry application on plant characters and yield of fresh waxy corn. The results showed that the plant height, stem diameter, ear height, ear length and yield of fresh waxy corn increased with the increase of biogas slurry application rate. When the biogas slurry application rate was 8000kg/667m² (treatment 4), it reached the highest level, and when the biogas slurry application rate was 9000kg/667m² (treatment 5), it was reduced, indicating that the appropriate amount of biogas slurry could promote the growth and development of corn, while excessive application of biogas slurry showed a certain inhibition effect. Through comprehensive analysis, it can be determined that the biogas slurry application rate in the production of fresh waxy corn should be controlled at 8000kg/667m2^.
