应用矮壮素、赤霉素及微量元素控制小麦生长发育的研究

A Study on the CCC, GA_3 and Trace Elements Controlling the Growth and Development of Wheats

在小麦拔节期喷矮壮素显著抑制了植株高度的延长,有利于形成理想株型。齐穗期喷赤霉素或微量元素,增加了麦穗长度,促进了干物质向结实器官转移,提高了收获指数,结果籽粒产量增加4～12％。

In this paper, the writer performed the experiment that the CCC was squirted on wheat plant at jointing stage and the GA_3 or the trace elements were squirted at boot stage. It turns out that the GA_3 or trace elements do not cancel out the effect of the CCC controlling the height of wheat plant. The regulators or the trace elements which promote the growth and development of the plant were spraied during the boot stage so that it increases the length of wheat ear and helps dry materials transporting into the reproductive organ. As a result, it increases not only the coefficient of the harvest in wheat but also the yield of wheat kernels by 4-12％.
