为了探索化学调控剂在大豆生产中最佳的使用方式及对大豆的增产潜力,实验设立D1、D2、D3、D4(对照)4种化控模式,不同生育期分析不同模式对春大豆单株叶面积、株高、茎粗及产量性状的影响。D1、D2、D3三种模式与对照D4处理间大豆单株叶面积、株高、茎粗和产量构成因素相比差异达显著水平,其中D3处理达到极显著水平,2010年在大豆始荚期和始粒期大豆叶面积分别提高36.3%和54.2%,鼓粒期株高分别降低7.4cm,茎粗增加0.19cm,产量高于对照15.2%。
In order to explore the best way to use chemical regulators in soybean production and the potential of increasing soybean yield, four control modes of D1, D2, D3 and D4 (control) were set up experimentally. Leaf area, plant height, stem diameter and yield traits. D1, D2, D3 three kinds of patterns and control D4 treatment leaf area per plant, plant height, stem diameter and yield components were significantly different, of which D3 treatment reached a very significant level in 2010 at the beginning of soybean pod And the initial grain-thickened soybean area increased by 36.3% and 54.2%, respectively, and the plant height at the grain-filling stage decreased by 7.4cm and 0.19cm respectively. The yield was 15.2% higher than that of the control.
