Workers cut off all the leaves from the bottom to 2-3 ears above the first ripe fruit, which not only facilitates the workers to pick, but also reduces the loss of nutrients, increases the air circulation and facilitates the later pruning and harrowing.
Extended data
Tomato is a warm vegetable. Under normal circumstances, the optimum temperature for assimilation is 20-25℃, and the optimum soil temperature for root growth is 20-22℃. Like light, the light saturation point is 70000lx, and the suitable light intensity is 30000-50000lx. It is also a short-day plant, and tomatoes like water. Generally, the soil humidity is 60-80% and the air humidity is 45-50%.
Tomatoes have low requirements on soil conditions and grow well in fertile loam with deep soil layer, good drainage and rich organic matter. The optimum pH value of soil is pH6-7. Tomatoes can tolerate drought, but not waterlogging, and the requirements for soil are not very strict. To obtain high yield, we must choose soil with deep soil layer, loose and fertile soil and strong water and fertility conservation.
