| 摘 要： | 为更好地预防春大白菜生产中的抽薹现象,提高春大白菜生产水平,本研究选用23个适宜不同季节栽培的大白菜品种,利用电子数据采集记录仪研究了春季气温、地温变化特点及其对春季大白菜抽薹的影响,并比较了人工春化大白菜种子和田间直播两种方法鉴定大白菜耐抽薹性的差异。研究结果表明,田间实测的24 h最低、最高温度与天气预报存在较大差异,增大了田间管理的难度。根据田间实测温度及其变化特点将春季气温、地温分成3个时间段,并根据其特点相应地提出了春大白菜栽培管理措施。

| Abstract: | In order to preferably prevent bolting and improve the production level of spring Chinese cab -bage , with 23 varieties suitable to cultivate in different seasons as materials , the variation characteristics of air and soil temperatures and their effects on Chinese cabbage bolting were studied by electronic data acquisition recorder .The differences of artificial vernalization and direct seeding in field were also compared in identifying the bolting tolerance of Chinese cabbage .The results showed that the lowest and highest temperatures in 24 hours in field were significantly different from those of weather forecast , which made it more difficult for field management .According to temperatures measured in field and their variation characteristics , the air and soil temperatures in spring were divided into three periods , and corresponding cultivation and management meas-ures of Chinese cabbage were proposed . |
