In the process of planting tomatoes, sometimes due to improper management of planters, or tomato seedlings, the control time is too long, resulting in weak growth of the tomato after emergence, and low survival rate, so today Xiaobian said Management measures after tomato emergence.

1. Pay attention to the order of the seedlings: It is advisable to control the tomato seedlings in the greenhouse for 80-90 days. Excessive time can make the tomato aging. It is usually planted in the middle and early November, and planted in the greenhouse in late January or mid-February of the second year.

2, timely seedlings: that is, timely transplanting. When the tomato seedling grows 1-2 true leaves, it can be transplanted by seedlings. It is not too late to transplant the seedlings.

3, temperature management is very important: when the tomato seedlings are unearthed, the requirements are 20-25 degrees during the day and 17-18 degrees at night. The temperature after the transplanting of the seedlings was slightly higher. The daytime is 25-27 degrees and the nighttime temperature is 18 degrees. After the seedling transplanting, the temperature is slightly reduced, requiring 20-25 degrees during the day and 12-15 degrees at night. The seedlings need to be seedling before the planting, and the daytime temperature is 22 degrees and the nighttime temperature is 12 degrees. Refining is required 7-10 days before planting, and the night temperature should be controlled within the range of 7-8 degrees.

4, water management should be appropriate: tomato seedlings excavated after the expansion of ventilation, to slowly reduce the soil moisture, covered with a layer of dry culture soil, try not to water before transplanting seedlings, when the tomato seedlings at noon when the leaves are wilting, you can Slightly spray the leaf water at noon on a sunny day. The seedlings are watered during transplanting, and then remain dry and not wet. In the stage of seedling exercise, water should be poured as little as possible, and water should be poured on the day before planting to facilitate seedling colonization.

5, conditional, you can use the seedbed electric heating to prevent frost damage.
