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

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