First, seedling raising and field planting.
1. Select suitable seeds, dry them in the sun for two days, and then sow them to raise seedlings.
2. Then soak the seeds in clean water for an hour or two, and then put them in warm water at 50-60℃ and stir constantly. This can prevent the seeds from being scalded, and reduce the water temperature and increase the temperature by adding water to the stagnant water. The whole process can be maintained at 15 minutes, which can break the dormancy of seeds, promote germination and have a certain bactericidal effect.
3. Finally, continue to soak the seeds for 3-5 hours before sowing.
4. After the seeds are treated, sow them in the seedbed. Don't sow too closely. It is best to plant about 30 seeds per square meter to keep the soil moist. The temperature is between 22-28℃, and it can sprout in about 3-4 days.
5. When tomato seedlings have 2-3 true leaves, the planting time should be February-May, July-September in autumn and winter, 165438+ 10 to February of the following year. When planting, the ground temperature should be controlled above 10℃, which is beneficial to root growth and improve survival rate.
Second, intertillage weeding
After planting, intertillage should be carried out in time to promote rapid rooting and slow seedling growth, and cooperate with intertillage to loosen soil and weed.
Third, fertilizer and water management
Fertilization is mainly based on base fertilizer. Apply plantar fertilizer in the planting area before planting, and basically do not use it later. If it wants to grow rapidly, it can be properly fertilized once or twice, and watered immediately after fertilization, which can reduce the fertility concentration and avoid burning roots. Usually watering should also be based on seasonal climate change. There is more water in dry season and less water in winter.
Fourth, scaffolding
Because plants will grow upwards, it is best to build a scaffold to climb upwards, which can support the growth of vines.
