How to grow tomatoes?

Every 667m2 tomato seedling needs seeds 15 ~ 20g. If you don't follow the seedlings before sowing, sow 20 ~ 25g seeds in 10 ~ 12m2 seedbed, and the cultivated seedlings can be sown in 667m2 field. If heel in is planted once before planting, the amount of seeds used in the above-mentioned sowing land will be doubled, and the cultivated seedlings can be planted in the field of 1334m2. Because the temperature is high when sowing, as long as the water is fully soaked, the seeds are usually dry. After sowing, the seedbed is thinly covered with a layer of burnt soil or decomposed soil miscellaneous fertilizer and covered with straw to prevent the influence of rain or rainstorm.
