高寒区棚室越夏硬果型番茄品种比较研究

Study on Comparative Experiment of Hardy Tomato Varieties

目的在张家口越夏棚室里筛选出生长势强,耐高温、高湿,果实硬度好(耐储运),座果率高,抗逆性强,一级果率高,适合市场销售的品种.以达到张家口市农业增效,农民增收的目的.方法以品种秀丽为对照,对引进的5个硬果番茄品种进行棚栽比较试验.分别在生长前期、中期进行性状调查,随机取样;采收期进行小区测产,三次重复,进行方差分析.结果4个品种表现均好于对照,其中,格雷生长势强,耐高温、高湿和寡照能力强,比对照高30.6%,果径比对照增大11.7%,一级果率高达80%,抗病性和产量性状最优,比对照增产72.3%,发病率降低19.9%.品种百灵的各项性状略低于格雷.两个品种从各方面性状均优于当家品种百利和对照品种秀丽.结论格雷是张家口市棚室越夏栽培的首选品种.品种百灵的各项性状略低于格雷,也是一个适合张家口市越夏栽培的优良品种.

Objective To Select hardy tomato varieties which bear resist-high temperature, resisithigh humidity, quality, resist-disease, hardness good and yield in summer plastic house located in Zhangjiakou, which are suitable for market sale in order to increase benefit in city agriculture and income to the farmer. Methods Comparative experiment on five hardy tomato varieties contrasts with Xiuli, than expect before grow respectively, the middle carry on sex form inquisition, taking a sample random. measure to produce on area, carry on mean square analysis again three times. Results The results showed four hardy tomato varieties were superior than contrast. The Gelei was superior to others. The resist-high temperature, the resisit-high humidity, few shine enlarge 30. 6%. The fruit diameter enlarge 11.7%. The class fruit rate was up to 80%. The anti-disease and the yield form are the superior, comparing to check against to boost production 72. 3%. The outbreak rate lower 19. 9%. Bailing was slightly low in Gelei. Two varieties with in all were surpass to BaiLi in general and XiuLi for contrast. Conclusion Gelei is the superior suitable variety for plant in plastic house in summer of Zhangjiakou. Also Bailing eharactei with in all is slightly low in Gelei, but is a good variety.
