Tomato planting time and technology, management is mainly weeding and fertilization

The planting time of tomato is February-May in spring, July-September in autumn and winter, and November-February in winter and spring. Planting techniques: it is appropriate to select the soil with deep soil layer, good drainage and irrigation and ventilation, first select high-quality seeds for seed soaking and sprouting, and so on when the seedlings grow to 3 true leaves, plan the planting density reasonably, carry out intermediate ploughing and weeding in time in the later stage, apply fertilizer scientifically, and set up a frame at the right time.

I. planting conditions and time

1. Reasonable land selection: it should be planted in good drainage and irrigation conditions, deep soil layer, good ventilation and permeability, and no eggplant fruits and vegetables have been planted in 3 years.

2. Planting time: generally spring tomato is from February to May, autumn and winter is from July to September, and winter and spring is from November to February.

Second, seed selection and budding

1. Seed selection: select varieties with high yield, resistance to storage and transportation, good commodity, disease resistance, high quality and suitable for market demand, such as Jin Tiewang and so on.

2. Soaking seeds in warm water before planting can break seed dormancy, effectively promote seed germination rate, and have a certain effect of sterilization and sterilization.

3. First, soak the seeds in clean water for about 2 hours, then remove them and put them in warm water of about 60 ℃, stirring continuously to prevent the seeds from being scalded. If the water temperature drops, continue to add water to raise temperature, this process takes about 15 minutes, and finally the seeds can be sowed after soaking in water for about 5 hours.

III. Timely planting

1. Sow the treated seeds into the seedbed, which is not suitable for intensive sowing. It is appropriate to sow about 30 grams of seeds per square meter. Be sure to keep the soil moist and the temperature is controlled at about 28 ℃. It will sprout in about 4 days.

2. When the seedlings grow 3 true leaves, they can be planted. When the soil temperature is stable above 10 ℃, it is the best to plant, which is helpful to promote root growth and improve the survival rate.

3. It is generally planted from the beginning of April to the beginning of May.

4. The plant spacing is about 60cm, the row spacing is about 1.3m, and it is the best to plant about 2000 plants per mu.

5, generally in cloudy days or sunny days after 4 pm colonization is appropriate, after planting need to be fully watered, about 5 days later need to be watered again.

IV. Post-management

The main results are as follows: 1. After planting, it is necessary to carry out intermediate ploughing and weeding in time, which is beneficial to promote rooting and slow seedling growth.

2. Fertilization is mainly based on base fertilizer, sufficient base fertilizer should be applied before planting, and only a small amount of fertilizer should be applied in the later stage.

3. Watering must be carried out in time after fertilization, which is helpful to reduce fertility concentration and prevent root burning. Generally, watering can be carried out according to seasonal changes, drought in summer can be watered more, a small amount of water can be watered in winter, and drainage can be carried out in time in the rainy season. to prevent excessive water from causing rotting roots.

4. general tomato varieties need to be planted on the shelf, except for a few upright varieties.
