高产大豆新品种临豆九号产量及主要经济性状的探讨

Discussion of Output and Main Economical Character for High Production Soybean New Variety Lindou 9

通过对黄淮南片大豆区试结果分析,表明临豆九号具有较好的丰产性、稳定性和适应性。该品种实现了产量构成因素的高度协调,产量与单株粒重、单株有效分枝、底荚高度、百粒重、单株粒数、株高、单株荚数呈正相关关系,只有主茎节数与产量呈负相关关系。生产实践中,应增加肥料投入,加强管理,促进植株养分向豆荚转移,增加大豆产量。

Through tries the result analysis to the Huang- Huai soybean area, indicated has the good yielding ability, the stability and the compatibility Lindou 9. This variety has realized the output constitution factor high coordination, the output and single plant grain heavy, the single effective branching, the bottom pod highly, hundred grains heavy, the single number of seeds, high, the single number of pod present correlational dependence, only then the main stalk pitch number and the output assume the inverse correlation relations, in the production practice, should increase fertilizer investment, enhance- ment management, promotion adult plant nutrient to the bean pod shift, increase soybean output.
