试验选取两个核心性苗用型大白菜品种早熟5号和双耐,春播之后观测各自的生长性状并对其进行对比分析。结果表明,作为苗用型栽培,二者十分相似,但双耐在耐抽薹性和综合性状上比早熟5号更为优秀。 Two core varieties of Chinese cabbage seedlings with early maturity 5 and double tolerance were selected in the experiment and their growth traits were observed and compared after spring sowing. The results showed that the two cultivars were similar in seedling culture, but double resistance was more excellent than bolting 5 in bolting and comprehensive traits.
