| Abstract: | Summer maize variety of Zhengdan958 was used to study the effects of plant growth regulator(PGR) on the growth and development of summer maize. The results showed that the stem thickness was increased, the length of inter-node near the basal part was shorted, root dry mass and root length were increased by the treatment of spraying one kind of PGR-Kangfengli, and increase the plants lodging resistance of maize. The grain yield was also increased to some degree. |
