Planting methods of Tomato Seeds

1. Determine the sowing amount:

General tomato seeds contain about 300 seeds per gram, according to the planting density, generally 20-30 grams per 667 square meters of field seeds. Each square meter of seeding bed can sow 10g to 15g. If the seed germination rate is less than 85%, the sowing rate should be increased appropriately.

2. Determine the sowing date:

According to the planting season, climatic conditions, cultivation methods, seedling facilities and other factors, the suitable sowing date was determined. For example, in open field cultivation in spring, seedlings are usually sown in Beijing from mid-February to early March. For open field cultivation in autumn, the effect of sowing in the south of the Yangtze River, such as Shanghai and Nanjing, is the best from late July to early August, while the yield of sowing in the eastern part of Sichuan is higher in early July. The output is also higher. In some areas where tomato diseases are serious, the sowing date can be postponed for 1 ~ 2 months, and then higher yield can be obtained through close planting, early coring, increasing fertilizer and water and other measures.

3. Sowing method:

There are usually broadcast, broadcast and on-demand. Tomato seeds should be covered with soil immediately after sowing, and fine screened soil should be used to cover the soil. The thickness of the covered soil is about 0.8cm to 1.0cm, and the thickness should be consistent. After sowing, 8 grams of carbendazim 50% wettable powder mixed with fine soil is scattered evenly on the bed surface after sowing, which can prevent the occurrence of seedling quenching disease. The surface of the seedling bed should also be covered with plastic film in winter and spring. The surface of the seedling bed should be covered with sunshade net or straw in summer and autumn, and the mulch should be removed when there is 70% seedling top soil.
