近几年来,先后从国内外引进一些夏季栽培的甘蓝品种,在海涂田进行多点栽培试验。由于结球期正值盛夏,高温（>25℃）持续时间长,参试品种结球率低,且很松散。去年,又引进国内外3个新品种,与往年优选的“K-K”甘蓝和主栽品种夏光甘蓝进行比较,旨在筛选耐热、耐盐、抗病、优质、高产,适于涂田栽培的品种,供大面积推广。 一、材料与方法 （一）供试品种:夏王（泰国）,爱华（泰国）,K-K（日本）,苏晨（江苏农科院）,以夏光（上海农科院）为对照（CK）。 （二）试验方法:试验于1997年5—8月,在瓯海区海滨镇涂田进行,土壤为淡涂粉砂质粘土,pH为8.62,表土氯化钠含量为 0.15％。随机区组排列,3次重复,小区面积 15m~2,定植 60株。5月 4日播种育苗,6月7日定植,8月7日和8月14日分2期采收,
In recent years, some varieties of cabbage cultivated in summer have been introduced from home and abroad successively, and multi-point cultivation experiments have been carried out in the field. Due to the positive summer mid-stage, high temperature (> 25 ℃) for a long time, the test varieties of low-rate ball, and is very loose. Last year, we introduced 3 new varieties both at home and abroad to compare with the best “KK” cabbage and cultivars of summer kale in the past years. The aim is to screen for heat-tolerant, salt-tolerant, disease-resistant, high-quality and high- The variety, for large-scale promotion. I. Materials and Methods 1. Varieties tested: Xia Wang (Thailand), Epworth (Thailand), KK (Japan), Su Chen (Jiangsu Academy of Agricultural Sciences) and Xia Guang (Shanghai Academy of Agricultural Sciences) as reference CK). (B) Test Method: The test was carried out in Tutian, Haibin Town, Ouhai District from May to August in 1997. The soil was lightly coated with silty clay with a pH of 8.62 and 0.15% of sodium chloride in the topsoil. Randomized block arrangement, 3 times repeated, plot area 15m ~ 2, colonization 60.
