摘    要:本文探讨了轮作,连作大豆根系中酚,糖含量与产量的关系以及施肥克服连作对大豆生长发育的障碍效应。采样观察并对根系中酚含量进行了定量分析,结果表明:连作大豆的根系不仅变褐严重,而且酚含量高于轮作大豆,连作施化肥对大豆根系内的酚含量无明显影响;连作大豆根系中总糖量低于轮作。

关 键 词:大豆  连作  根系  酚含量  糖含量  产量

Abstract:This study shows that continuous and rotation effects on the content of phenol of soybean root system and yield of soybean. Besides this, applying fertilizer overcomes obstruct of continous cropping for the growth and development of soybean. By collecting samples the content of phenol of root system was determined. The result shows that the soybean root in the continous cropping was not only brown, but also with higher phenol content than the rotated soybean. However the fertilizer applying effects on content of phenol is not noticeable in the soybean root system between the continuous and rotated soybean, but in the continuous cropping the total sugar of soybean root system is lower than that in the rotation.
Keywords:Soybean  Continuous cropping  Phenol  Suger  Yield
