To cultivate tomato seedlings in the greenhouse, when the seedlings grow to the same time, they will be divided into seedlings. Points to pay attention to the following three points:
One is to pay attention to the seedling grading due to the pre-sowing germination is not neat, there are differences in the depth of sowing, the seeds after sowing are far from the heat source, the size of the seedlings grow is also inconsistent. Therefore, when the seedlings are divided, the seedlings should be divided into the south side of the greenhouse, and the seedlings should be distributed to the north side of the greenhouse. The seedlings should be located near the heat source, and the middle seedlings should be distributed in the middle of the greenhouse.
Second, the depth of seedlings should be emphasized to ensure consistent seedlings, and the seedling planting depth should be adjusted when seedlings are divided. Planting deeper near the heat source, slightly passing through the leaf segments; planting lighter away from the heat source to expose the cotyledons; where moderate heat is available, the cotyledon segments of the seedlings after transplanting should be level with the ground.
The third is not to pinch seedling stems and stems more tender stems, easily cause damage. The correct method of transplanting the seedlings is to gently pinch the cotyledons of the seedlings and put them into the seedlings.
