植物生长调节剂丰优素对小麦产量因素及容重的影响

Effect of Plant Growth Regulator-Fengyousu on the Yield Factor and Volume Weight of Wheat

研究了植物生长调节剂丰优素对小麦产量因素及其容重的影响。结果表明,在灌浆盛期末喷施丰优素可显著提高小麦千粒重;对穗粒数、单穗重和容重也有不同程度的促进作用,但均未达显著水平。田间观察表明,喷施丰优素对延长小麦后期叶片功能,抵御干热风有一定作用。

Effect of plant growth regulator-Fengyousu on the yield factors and volume weight of wheat was studied. The result showed that spraying Fengyousu in the terminal stage of peak grain filling can increase 1 000-grain weight of wheat significantly. Although it had some different promotion actions to grains per ear, weight per ear and volume weight, not reaching t0.05 significant level. Field observations indicated that spraying Fengyousu had a certain effect on lengthening leaf function and resisting dry-hot wind in the growth later period of wheat.
