Breeding seedlings

Soak the seeds in hot water of 50 to 55 degrees for 30 minutes and stir until it reaches room temperature. The amount of water should not be too large. If there are only a small amount of seeds, a small bowl of water is usually enough. Remove the seeds and wash them with clean water, then soak them in clean water for 6 to 8 hours. After removing them, wrap them in wet gauze and place them at about 26 to 30 degrees for germination. Pay attention to moisturizing. Generally, germination boxes are used for germination if conditions permit. Sowing can be done when about half of the seeds are white.

Seedbed

Try to use prepared nutrient soil or fertile and loose pastoral soil in the seedbed. Do not use chemical fertilizers. Apply a small amount of fully decomposed organic fertilizer. Water the seedbed thoroughly, and after the water seeps down, mix the seeds with sand and spread them evenly on the seedbed. You can also use plug trays or nutrient bowls to raise seedlings. Then cover the seeds with soil by about 0.5CM, and build a shed on top to retain moisture. Ventilation management of seedbeds should be strengthened to prevent damping-off disease in a timely manner. During the seedling stage, 0.2% potassium dihydrogen phosphate can be sprayed to strengthen the seedlings. Keep the seedbed moist. Do not water too much to prevent excessive growth. Seedlings must be hardened appropriately.

Colonization

Apply fully decomposed organic fertilizer and a certain amount of compound fertilizer to the soil. Generally, 2,000 to 4,000 kilograms of soil fertilizer and 50 kilograms of ternary compound fertilizer per mu are applied. When planting, generally use high ridge double rows or single rows for planting. The specific row spacing should be selected according to your own planting method. Just water the planting hole enough, plant the seedlings, cover them with soil, and then spread them with mulch. The mulch must be pressed well, including the roots, which must also be buried with soil.

Post-plantation management

Before the first ear of fruit swells, watering is generally not done. If there is indeed a drought, you can water it lightly to strengthen the seedlings and prevent them from growing too much. There is no shortage of water during the flowering period and the soil must be kept moist. If black pearl cherry tomatoes are grown in the open field, it is recommended to use double-stem pruning. If they are planted densely in protected areas, single-stem pruning is often used. Work such as pruning, tying vines and cutting branches should be carried out in a timely manner.
