摘要
为明确钾肥用量对糯玉米(Zea mays L.)植株茎粗和株高的影响,设置不同钾肥梯度进行试验.结果表明,糯玉米植株茎粗和株高都随着其生育期推进而增加并在抽雄期达到最大,随后保持不变;同一生育期内,茎粗和株高都随着施钾量增加而增加,同时,施钾量、茎粗和株高三者之间分别呈显著正相关关系(r> 0. 8).
Different levels of potassium fertilizer were used to study the effect of potassium fertilizer on stem diameter and plant height of waxy maize. The results showed that the stem diameter and plant height of waxy maize increased with the growth period and reached the maximum during the tasselling stage and then remained unchanged. Furthermore, potassium fertilizer could increase the stem diameter and plant height in a dosage dependent manner at the same growth stage. In addition, there was significant positive correlation between potassium fertilizer, stem diameter and plant height （ r 〉0.8）, respectively.
