本文为白菜地方品种初步研究的第二部分。系1954、1959、1960年在南京对150余份白菜地方品种主要生物学特性的研究。采用分期播种与阶段发育的分析,鉴定了不同类型品种的生育期及发育特性的基本规律。并对其耐寒性、耐热性、抗病性、晚抽苔性和食用品质进行了田间与室内鉴定,为生产上获得白菜周年均衡、高产、稳产、优质的栽培技术如:促进成熟,提早采收;选择适当的播种季节和不同成熟期的品种搭配与茬口安排,及引种和新品种的选育等,提供科学依据及基础资料。
This article is the second part of the preliminary study on the local varieties of cabbage. In 1954, 1959, 1960 in Nanjing, more than 150 parts of the main biological characteristics of Chinese cabbage. By staging sowing and stage development analysis, the basic rules of different types and varieties of the growth period and development characteristics were identified. Field and indoor identification were conducted on its cold tolerance, heat resistance, disease resistance, late bolting and edible qualities. The cultivation of cabbage was balanced in annual production, with high yield, stable yield and high quality cultivation techniques such as promoting maturity, early maturity Harvest; choose the appropriate seeding season and maturity of different varieties with crop arrangement, and introduction and selection of new varieties, provide scientific basis and basic information.
