Tomato planting has a long history, after many years of cultivation of many varieties, can adapt to the environment ability to substantially improve the planting time with the region's climate and temperature. Spring tomato planting time in February-May, fall and winter stubble planting time is generally in July-September, winter and spring stubble planting time in November to February of the next year.
Planting method
1, seed treatment
Pre-planting of seeds in warm water, which not only breaks the seed dormancy and promotes germination, but also has a certain sterilizing effect. First soak the seed seeds in water for an hour or two, and then put the seeds in warm water at 50-60 degrees, stirring constantly, so as to prevent the seeds from scalding, the water temperature reduces the cumulus plus water to warm up, the whole process is maintained at about 15 minutes. Then the seeds continue to soak for 3-5 hours can be sown.
2, sowing and planting
The seeds will be treated, sown in the seedbed, sowing should not be too dense, about 30 grams of seed per square meter of the best, keep the soil moist, the temperature between 22-28 degrees, about 3-4 days to germinate. But seedlings grow two or three true leaves, can be planted, planting the ground temperature stabilized at 10 ℃ or more, which is conducive to root growth, improve the survival rate.
3, field management
Planting should be carried out in a timely manner after plowing to promote rapid rooting and seedling growth, with plowing loosening and weeding, fertilizer based on base fertilizer, before planting on the cultivation site of the bottom of the full fertilizer, the late basic do not need to fertilize, if you want to grow quickly, can be appropriate to fertilize one or two times the Wo leaf particles of water-soluble fertilizer.
Fertilizer should be watered immediately, so as to reduce the concentration of fertilizer, so as not to burn the roots, usually watering also need to water according to seasonal climate change, drought season should be more watering, as little as possible in the winter watering, the rainy season should be a good drainage measures, so as to avoid excessive water and lead to rotten roots. In addition to a few upright varieties of tomatoes, the rest of the varieties need to be cultivated on the shelf.
