Tomato seedlings 15-20 cm, transplantable
The time from planting to transplanting of tomatoes is about 40-45 days. Tomato seedlings with short internodes, thick stems, developed roots, strong growth potential and 3-4 true leaves are selected. At this time, the best time for planting seedlings can be transplanted, and the survival rate in the future is high.
1. Transplanting
In the process of transplanting, sufficient water shall be poured on the seedlings first, and then the tomato seedlings and the soil shall be pulled out, and the seedlings shall be planted in the land according to the distance of 40cm between the seedlings. The seedlings shall not be too close to each other, which will be unfavorable to the later growth. The row spacing can also be controlled to facilitate the later picking management.
2. Temperature control
After the tomato seedlings are transplanted and planted, the temperature should be controlled between 25-30 ° C, and the temperature at night should not be lower than 15 ° C. when the summer is high, the seedlings should be watered in time to reduce the temperature, or a shade shed should be built for the tomatoes to prevent rain in the rainy season, and high temperature and strong light in summer.
3. Fertilizer and water management
Tomato seedlings should be watered once every 3-5 days after planting. As a result, they can be watered once every 7-10 days in the early stage. In the later stage, the watering frequency can be adjusted according to the growth and development of the plant, and the principle of watering after the soil is dry can be followed. After transplanting, fertilizer can be applied once every 15 days, mainly compound fertilizer, and foliar fertilizer can be sprayed once in the later stage.
