营养型化控剂(FC)对玉米全程生育调控效果初探

Study on the Effect of Chemical Regulator(FC) on the Growthand Development of Maize

利用生物化学分析和田间试验相结合的方法,于2001～2002年系统研究了营养型化控剂FC在密植条件下对玉米根、茎、叶、产量器官的调节作用及最适应用技术。结果表明,应用营养型化控剂FC处理后,可以使玉米植株各个器官生理功能都得到不同程度的调控,显著改善果穗性状,减少秃尖,增加穗粒数,提高玉米产量。一般在密植条件下可使玉米群体产量提高12%以上。

The method of biochemistry analysis combined with field trial were used to study the optimum applied technology and regulation effect of nutrient chemical regulator(FC) on root、 stem、 leaf and yield organ under the condition of compact planting of maize in 2001 and 2002. The result showed that the nutrient regulator(FC) could adjust the physiological function of many organs of meize plant by enhancing kernel number and yield,reducing the barren ear tip ,improving ear shape etc.It could increase maize yield about 12% at higher densities.
