大棚樱桃番茄主要农艺性状的边际效应分析

Analysis on the Marginal Effect of the Main Agronomic Traits of Cherry Tomato in Greenhouse Cultivation

为研究樱桃番茄大棚栽培中的边际效应,以樱桃番茄黄妃自交系为材料,调查分析株高、叶片大小、茎粗、节间长、果实大小等主要农艺性状表现。结果表明:东面和中间植株普遍较高,南面株高大于北面;东面和中间植株叶片普遍较大;东面植株茎粗大于西面,南北相近;西面植株节间长大于东面,南北两端较中间短;果实整体稍长,但中间比各边际果实圆。研究显示大棚东、南和中间部分番茄长势较好,且南北端的边际效应明显大于东西端,西面和中间植株节间长则表现出大于东面的现象。

In order to study the marginal effect of Lycopersicon esculentum var.cerasiforme in the greenhousecultivation,by using the cherry tomato Huangfei inbred line as the material,the main agronomic traits such as theplant height,leaf size,stem diameter,internode length and fruit size were investigated and analyzed.The resultsshowed that the plants planted in the east and middle of the greenhouse were generally higher,and the plant height inthe south was higher than that in the north.The plant leaves planted in the east and middle of the greenhouse weregenerally larger,while the stem diameter of plants planted in the east was larger than that in the west,and similar inthe north and south.The plant internodes planted in the west of the greenhouse was longer than those in the east,andthe plant internodes in the north and south of the greenhouse were shorter than those in the middle.The fruit wasslightly longer overall,but rounder in the middle than at the edges.The results showed that the tomato plants grewbetter in the east,south and middle areas of the greenhouse,and the marginal effect of cherry tomato in the north andsouth of the greenhouse was significantly greater than that in the east and west,while the internode length of the plantsgrowing in the west and middle areas was greater than that in the east.
