濉溪县夏大豆产量低而不稳原因分析及对策

Reason analysis and the countermeasure for low and unstable summer soybean yield in Suixi county

在分析安徽省濉溪县大豆产量低而不稳原因的基础上,提出了大豆生产再上新台阶的技术对策。(1)大豆产量水平低,增产速度缓慢,产量波动不仅略高于生育期间灾害频繁的小麦,也明显高于同一生育期和相同环境条件下生长发育的夏玉米。(2)品种更新缓慢、施肥不足、重茬面积大和病虫害发生频繁是大豆低产的主要原因;6月中下旬的降水量,花荚期的雨日、鼓粒期的日照时数和9月中旬的平均温度是导致大豆产量波动的主要气象因子。(3)实现大豆生产再上新台阶,必须加快品种更新换代,科学运筹肥料,适期播种,及时防治病虫草害,合理灌排。

Based on the analysis to the reasons of low and unstable yield in Suixi County soybean yield, to step up a new level were proposed. Variety renewal, scientific fertilization, timely sowing and control of pest and diseases, as well as rational irrigation are the main points to be used.
