丰尔安对冬小麦生长的调节效应

The Regulation Effects on the Growth of Winter Wheat by Fengeran

研究了丰尔安在冬小麦上的应用效果。结果表明:小麦起身期喷施100-300mg／kg 丰尔安溶液300 kg／hm2,可有效控制小麦营养生长,抑制小麦节间伸长,降低小麦株高3．3 -5．0 cm,分别缩短基部1-3节节间长度0．6-1．7 cm、0．4-0．7 cm和0．5-0．8 cm;明显增强小麦抗倒伏能力;分别增加小麦单位面积穗数、穗粒数、千粒重和产量17．1万-27．45 万穗／hm2、0．5-1．6粒、0．2-0．6 g和4．45％-9．04％。

The application effect of the growth regulator Fengeran on winter wheat was studied. The results showed that the application of 300 kg/hm^2 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/hm^2, 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%.
