摘要
在田间以新鲜豆1号为材料研究了5种不同密度对菜用大豆根系生长及产量的影响。结果表明:随密度的增加,根系干重、空间分布根量、伤流量、根系还原强度及产量基本呈现先增后减的趋势,而根冠比却呈现相反的结果。以种植密度13.5万株/hm2时,根系综合性状最佳,产量最高,为15185.50kg/hm2。
with the fresh vegetable soybean number 1 as the testing material,the effects of five different levels of density on root growth and yield were studied at the field.The result showed that： With the increase of plant density,the root dry weight,the spatial distribution root quantity,bleeding sap, root activity and yield increased at first and then decreases.But ratio of root/top showed the opposite results.Considering the vegetable soybean fresh pod yield and root system comprehensive characters,the 135 thousands plants per ha treat was proper, yield is 15185.50kg per ha.
