【摘要】 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。更多还原

【Abstract】 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.更多还原
