The Regulation Effects on the Growth of Winter Wheat by Fengeran

The application effect of the growth regulator Fengeran on winter wheat was studied. The results showed that the application of 300 kg/hm2 of Fengeran solution with the concentration of 100 - 300 mg/kg at early jointing stage, the vegetative growth of winter wheat was effectively controlled and the elongation of node length inhibited, the plant height was reduce by 3. 3-5. 0 cm; the 1-3 node length of winter wheat foundation were respectively inhibited. The first length was inhibited by 0. 6 - 1. 7 cm, the second length was inhibited by 0. 4 - 0. 7 cm, the third length was inhibited by 0. 5 - 0. 8 cm. the lodging resistance capability was strengthened obviously; the panicle number per unit was increased by 1 710 000-27 450 000 panicle/hm2、the grain number was increased by 0. 5 - 1. 6 grain、the 1 000-kernel weight was increased by 0. 2-0. 6 g, and increase the yield by 4. 45%-9. 04%.
