【摘要】 为选择南方地区春作大白菜露地生产的优良品种,对5个春作大白菜品种进行对比试验,比对其生物学性状、产量和抗病性等指标。试验表明,5个参试大白菜品种中,综合性状表现较好的品种有"白蓝"和中白60,表现为生育期短,产量较高,综合抗病性较好;早熟5号和春夏王在本次试验中表现不佳,产量较低,综合抗病性不强,结球紧实度稍差;京春白的产量最高,但是其生育期最长,"白蓝"的综合抗病性最好,抗病毒病、霜霉病和软腐病。更多还原

【Abstract】 IN order to select fine variety for open-field spring Chinese cabbage production in Southern China,five varieties are chosen as materials of comparative experiment to compare the index of biological characters,yield and disease-resistance.The results show that Bailan and Zhongbai 60 are better in integrated character among five varieties,which represent short growth period,higher yield,better integrated disease-resistance.However,earlier-ripened No.5 and Chunxiawang are not so good in this experiment,which represent lower yield,weak integrated disease-resistance and loose leaf-ball.Jingchunbai has the highest yield,but longest growth period,while Bailan has best integrated disease-resistance for virus disease,downy mildew and soft rot.更多还原
