Control of corn flourishing, ultra-high yielding new technology. Said control Wang, that is, 6 to 12 leaves in the spray when sprayed with fertilizers, shorten the corn internode, more than a layer of overlord root, lodging resistance, while the concentration of nutrients attack big spike, anti-bald spike to achieve the spike Long super-high yield.
