试验精选四种高油大豆东农46、黑农38、合丰41、绥农14,根据不同生育时期进行腐植酸专用叶面肥喷施对比试验,对喷施后大豆生物性状、产量及粗脂肪含量等方面进一步研究。试验结果表明绥农14喷施效果突出:处理后大豆生物性状与对照无显著性差异,产量与对照差异显著,处理1和处理2分别比对照增产15.9%和13.9%,单位面积粗脂肪含量有较大提高。
Four kinds of high-oil soybean Dongnong46, Heinong38, Hefeng41 and Suinong14 were selected to test the effects of spraying humic acid on foliar fertilizer at different growth stages. Crude fat content and other aspects of further research. The results showed that the spraying effect of Suining 14 was outstanding. There was no significant difference between the treated and the control, the yield and the control had significant difference. The yield of the treatment 1 and 2 were 15.9% and 13.9% higher than that of the control respectively. The crude fat content per unit area Larger increase.
