- 摘要:
- 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。
- Abstract:
- The method of biochemist ry analysis combined wi th field trial w ere used to study the optimumapplied technology and regulation effect of nutrient chemical regulato r(FC)on root 、stem 、leafand yield organ under the condition of compact plant ing of maize in 2001 and 2002 .The result show edthat the nut rient regulator(FC)could adjust the physiological function of many o rgans of meize plantby enhancing kernel number and yield , reducing the barren ear tip , improving ear shape etc .It couldincrease maize y ield about 12 % at hig her densities .
