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
Before planting, the land should be plowed and plowed deeply, plastic growing bag and crop rotation should be carried out without continuous cropping. 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.
Pollination of flowers
Artificial pollination or bumble bee pollination can be carried out, and hormones such as anti-falling hormone can also be used for spraying.
Fertilizer and water management
Black pearl tomatoes like fertilizer and water. Water less fertilizer and water before fruiting. Increase the supply of fertilizer and water after fruiting. Do not apply too much nitrogen fertilizer and increase the proportion of potassium fertilizer.
Pests and diseases
Pest and disease control must be timely and comprehensive. The main pest is whitefly, which can be trapped and killed by hanging yellow insect traps, or controlled with pesticides such as chlorpyrifos. The main diseases are gray fog, blight, leaf mold and other diseases, which can be controlled with targeted pesticides.
What are black pearl tomatoes
Black Pearl Tomato is a new tomato variety introduced from abroad in recent years. The fruit is red and black. It is used both as medicine and food. It has high nutritional value and is suitable for fresh eating. In European and American countries, black pearl tomatoes are currently a very popular high-quality health-preserving fruit and vegetable, and the product is in short supply. In recent years, it has also been produced and sold in many cities in my country. Ningxia is located in the inland area of the west, with sufficient sunlight, moderate temperatures, drought and little rain. However, it is irrigated by the Yellow River and is very suitable for tomato production and cultivation. Black pearl tomatoes can be grown in protected areas and open fields in Ningxia. Generally, the yield per plant is 2 to 4 kg, and the yield per plant can reach 100,000 to 130,000 kg/km2.
Characteristics of Black Pearl Tomatoes
Black Pearl Tomato is a first-generation hybrid introduced from abroad. It is an unlimited production type with medium maturity. It takes 60 to 65 days from planting to first harvest. The plants grow vigorously and have strong continuous fruiting ability. Each ear bears more than 10 fruits. The fruits are spherical, red and black, and the single fruit weighs about 20g. The shape and color of the fruit are similar to Kyoho grape fruits. The taste is moderately sweet and sour, with a strong tomato flavor, and is especially suitable for fresh eating. It has wide adaptability, good heat resistance, moderate cold resistance, and resistance to leaf mold and late blight.
