After the tomato colonization, some vegetable farmers suspected that the seedlings were growing weakly and increased the supply of fertilizer and water during the seedling stage, resulting in serious tomato growth. The first and second spikes were significantly smaller, and there were more malformed fruits. Therefore, the tomato seedling stage should be as little as possible watering or not watering, nor fertilize, when the first fruit of the tomato has the size of the walnut when the amount of rushed three yuan high potassium compound fertilizer to promote fruit enlargement. After applying high potash fertilizer twice, the nitrogen, phosphorus, and potassium balance fertilizers should be applied once to avoid the high potassium content of soil nitrogen and affect plant growth.
The seedlings of the early seedlings are thin but not hollow, the leaves are small and thick, and the leaves are dark green. This kind of tomato seedlings can obtain high yield in the later period; on the contrary, the seedling stage has sufficient fertilizer and water, the seedling stems are thick and hollow, the leaves are large and tender, and the leaf color is relatively Pale, such tomato seedlings are leggy seedlings, but not strong, often the first fruit to the third fruit set fruit rate is low, the fruit is small, resulting in low early yield. The main reason for causing tomato seedlings to grow seedlings is excessive growth of nutrients at the seedling stage, which affects reproductive growth and causes vegetative and reproductive growth imbalances.
Tomato seedling management should grasp the word “control†to increase the yield, especially to increase the previous production. In addition to controlling water and fertilizer, it should also pay attention to temperature control. Found that there are signs of leggy plants, should be timely control of the temperature within the shed, to avoid excessive temperature, while widening the temperature difference between day and night, the temperature should be at 10 °C; or use a plant growth regulator such as piperidine control Wang, pay attention to the liquid concentration can not be too large.
