What is the reason for the slow expansion of tomatoes in greenhouses
The main reasons for the slow expansion of tomatoes are as follows: 1. Poor soil fertility and insufficient soil organic matter content. Many vegetable greenhouses are sandy soils, which have poor water and fertilizer retention capacity, and plants cannot obtain essential nutrients from the soil. 2. Poor heat preservation of the shed, low light transmittance of the shed film, and conditions such as temperature, humidity and light in the shed cannot satisfy the growth of tomatoes. There are some drawbacks in the construction of the shed, such as the angle of the rear roof is too small, the shed surface is small, and the cover is thin. Such facilities have poor thermal insulation, which affects the light transmittance of the shed film, and cannot meet the suitable temperature requirements for tomato growth (25°C-30°C during the day, 15°C-18°C at night, and keeping the temperature difference between day and night between 15°C and 17°C is conducive to fruit expansion) And lighting conditions. 3. Excessive leaf picking, injury of stems and stalks of fruit. Vegetables mainly produce organic products through photosynthesis of leaves, which are then transported to the fruit for expansion. If the leaves are picked too early and too heavy, the effective photosynthetic leaves of the tomato plant will decrease, which will inevitably affect its normal growth, including fruit enlargement.
