Cherry tomato is relatively drought-tolerant, but not waterlogged. It is best to plant it on weakly acidic sandy soil with good drainage, deep soil layer and rich organic matter. Cherry tomatoes like to grow in warm and bright places, and the most suitable temperature for growth is 2 1 ~ 30℃. Water and fertilize quantitatively every day, so that the cherry tomatoes are in a state of insufficient water and fertilizer. Insufficient water and fertilizer will promote the reproductive growth of plants. The small tomatoes planted in this way have thin stems, small leaves, beautiful colors and uniform coloring.
In order to prevent the seeds from carrying bacteria, the seeds should be disinfected before sowing. Seeds can be soaked in warm water or chemicals. Soaking seeds in warm water is to soak seeds in cold water for 10 minute, and then put them in hot water at 50℃~ 55℃. There is no need to apply fertilizer before fruit setting at the initial stage of growth, and the amount of fertilizer applied will be gradually increased after fruit setting. According to the growth situation, high-potassium compound fertilizer with the concentration of 1: 100 times should be applied to the basin surface, and the rice discarded in daily life should also be put into wooden barrels.
Seedling 1~2 true leaves are seedlings. Seedlings were divided in a seedling cup with a diameter of 8~ 10 cm, and the soil in the cup was watered with sufficient water. After sterilization, plant a plant in each cup. After the seedlings are separated, they are kept at 25~30 degrees during the day and at 16~ 18 degrees at night. Top dressing is started when the first ear begins to swell, and 200 kilograms of organic fertilizer is applied per mu, or 20 kilograms of compound fertilizer is applied with water, and then top dressing is performed every 15 days. Spraying potassium dihydrogen phosphate on leaves every 7 ~ 10 days during the growth period is beneficial to increase production.
