植物生长调节剂“立多”对小麦产量的影响

为研究植物生长调节剂"立多"对小麦产量的影响。通过田间试验及生产示范,分析了喷施不同浓度(100、2003、004、005、00 mg/kg)的新型植物生长调节剂"立多"450 kg/hm2与小麦产量的相关性。喷施"立多"的浓度为100~300 mg/kg时,其浓度与小麦产量呈比较强的正相关;喷施"立多"的浓度为300~500 mg/kg时,其浓度与小麦产量呈负相关。喷施不同浓度的"立多"均引起了小麦株高的下降,"立多"浓度与小麦株高呈明显的负相关关系。在河南省商丘地区施用"立多"有明显的增产作用,以300 mg/kg效果最为突出。

Effects of Plant Growth Regulator-Liduo on Wheat Yield

The aim of the study was to investigate the effects of plant growth regulator-Liduo was on wheat yield.Through field experiment and production demonstration,the correlation between a new type of plant growth regulator-Liduo(450 kg/hm2)at different concentrations of 100,200,300,400 and 500 mg/kg and wheat yield were analyzed.When the spraying concentration of Liduo was 100～300 mg/kg,the concentration had a strong positive correlation with wheat yield.When the spraying concentration was 300～500 mg/kg,the concentration had a negative correlation with wheat yield.The different concentrations of Liduo all led to the decrease of wheat plant height and the Liduo had an obvious negative correlation with wheat plant height.The application of Liduo in Shangqiu area of Henan province had obvious effect on the yield-increasing,and the most prominent effect was at the concentration of 300 mg/kg.
