对砂壤土上重茬大豆生长发育情况及调控措施进行了初步研究。结果表明:砂壤土上重茬大豆生长发育各项指标受连作影响均不同程度低于对照,重茬大豆成熟期的株高、植株干重和产量与正茬大豆相比分别降低了1.86%、56.54%和20.99%。2种调控措施均减轻了连作障碍,微肥处理重茬大豆成熟期时植株干重和产量分别比普通重茬大豆增加了108.96%和114.76%;优选种子处理株高、植株干重和产量分别比普通重茬大豆增加了7.80%、47.67%和67.53%。
The growth and development of stubble soybean on sandy loam and regulation measures were studied. The results showed that the index of growth and development of stubble soybean on sandy loam soil was affected by continuous cropping to varying degrees lower than the control. The plant height, plant dry weight and yield of stubble soybean decreased by 1.86%, 56.54% And 20.99%. The two kinds of control measures reduced the continuous cropping obstacle. When the micronutrient fertilizer was used to treat the stubble soybean, the dry weight and the yield of the stubble increased by 108.96% and 114.76% respectively compared with that of the ordinary stubble soybean. The optimal seed treatment plant height, plant dry weight and yield were respectively Replanting soybean increased by 7.80%, 47.67% and 67.53%.
