摘要
以大白菜和分蘖洋葱为试材,采用盆栽方式,研究了轮作分蘖洋葱对大白菜生长、品质及产量的影响。结果表明:分蘖洋葱轮作对大白菜植株的各项生长指标均具有促进作用,定植60d后显著促进了大白菜植株株高、叶片数和干重(P<0.05)。分蘖洋葱轮作对大白菜叶片可溶性糖含量和硝酸盐含量的积累没有影响。另外,分蘖洋葱轮作对大白菜单株产量无显著影响。总之,分蘖洋葱轮作可以促进大白菜植株生长,而对植株品质和产量的提高无促进作用。
Taking Allium cepa and Brassica rapa as material,with a pot experiment,the effect of rotation with Allium cepa on the growth,quality and yield of Brassica rapa were studied. The results showed that when rotation with Allium cepa（LZ） ,all of the growth indexes of Brassica rapa were better than the treatment of continuous cropping of Brassica rapa（CK）. The rotation of Allium cepa increased the height,the number of leaves and the dry weight of the Brassica rapa signifieantly（P^0. 05） in 60 days. While the content of soluble sugar and nitrate were not effeeted by LZ compared with CK,and the single plant yield of Brassica rapa wasn＇t promoted by LZ either. In conclusion,the growth of Brassica rapa could be improved by the rotation with Alliurn cepa, hut it had no effect on promoting the quality and yield of plant.
