大豆超高产技术试验增产效果的研究

Research on technology of soybean super high yield for yield-increasing effect

利用龙选1号和绥农14为材料研究大豆超高产技术在不同生态区对大豆生长和产量的影响。结果表明:"三良五精"技术组装合理,可以提高大豆产量,各试验点平均较对照增产27%;龙选1号增产潜力大,在2007年严重干旱气候条件下,各点平均株高94.0cm、主茎节数16.5个、单株荚数30.6个、单株粒数74.4个、百粒重18.9g,明显好于绥农14。

In the study,Longxuan No. 1 and Suinong No. 14 were used to investigate technology of super high yield in soybean effects on soybean growth and yield at different ecological regions. The results showed that Three Qualities and Five Precisions technology was assembled reasonably, which improved the yield of soybean significantly. Soybean in different experimental farms produced 27% more yield than that of contrast averagely; And Longxuan No. 1 had great productoin potential, even though under the condition of influences of extreme climatic condition to soybean yield seriously in 2007. The average plant height of Longxuan No. 1 was 94.0 cm, node numbers of main stem, pod numbers of single plant, and grain numbers of single plant were 16.5, 30.6, 74.4 respectively, hundred - seed weight of Longxuan No.1 was 18.9 g. all above the characters of kongxuan No. 1 were much better than those of Suinong No. 14.
