| 摘 要： | 在玉米高产栽培过程中，由于种植密度加大，倒伏、秃尖等现象常常出现，制约了玉米产量的提高。本试验研究了玉黄金不同量级、不同施用时期对玉米化控作用。结果表明：玉黄金主要控制基部1-5节节长，使茎秆缩短、粗壮，叶色深绿，株高、穗位降低20-50cm；施用量越高，矮化作用越明显，以300mL·hm^-2为宜；施用时期以玉米展开叶6片时施用为宜。

| Abstract: | As high population, lodging and bare top ear occurring on maize in course of cultivation, the yield is always restricted. The effect of plant growth regulation substance (PGRS) with different dosages and different using period of Yu-Huang-jin have been investigated. The result indicated that Yu-Huang-Jin can distinctly dominate the length of the fwst to fifth basic intemodes, shorten stem, enhance stem width, increase the content of chlorophyll and reduce the plant height and ear height from 20 to 25 cm. We stage. |
