Black tomato seedling transplanting and management techniques:
Climatic conditions: It can be planted all over the country, but the temperature is stable between 12-35 °C, suitable for planting in open fields, shading above 35 °C; greenhouse cultivation below 10 °C.
Site preparation: transplanting and planting black tomato plots should be carried out 25-30 cm deep.
Adding base fertilizer: Generally, 10 kg of mixed compound fertilizer and 10 kg of superphosphate are applied per mu of farmer's fertilizer. Each acre can also be used as a basic base fertilizer by adding 10 kg of fully fermented vegetable cake fertilizer.
Planting and irrigating: The day before planting, the seedbed will be poured into the bottom water, and the next day, the shovel will be cut, and the drainage ditch will be dug deep to reduce the accumulated water. It is necessary to pay attention to the large soaking during planting and after planting and before fruit setting.
Planting seedlings: After the seedling height is 10-25 cm, 5-7 pieces of true leaves or seedling age 50 days, choose the windless sunny day to plant in time, and plant the best before raining. After planting, you must pour enough water at a time to set the roots.
Planting density: Generally 2000 plants are planted per acre. The black tomato variety is suitable for the north and south as a good one. It is recommended that the width of the black tomato is 1 meter and the planting is 2 rows with a plant spacing of 35 cm.
Planting depth: Do not plant too deep or too shallow when planting seedlings (3-4cm is suitable for soil). At the time of planting, it can be placed at a 45-degree angle (the tip of the stem exposed above is slightly inclined to the south) to reduce the height of the seedling on the ground, to promote adventitious roots, and to prevent the burning of the sun.
Inserting vines: Adjusting vegetative growth and reproductive growth, promoting sputum, fruit and prosperity. Black tomato scaffolding is mostly made of herringbone frame, square frame and nylon rope. Generally, when the first layer of inflorescences is found, it is necessary to tie the vines. It is necessary to be tight and moderate, leaving room for stem growth.
Pruning: The black tomato is planted in the open field to leave the main stem, and only 1-2 side branches are left in the first inflorescence. Take care to avoid pruning before raining, when it is raining, or when the dew is not dry. In the later stage of growth, the old leaves, diseased leaves and diseased fruits should be removed to facilitate ventilation and light transmission, reducing pests and diseases.
Topdressing and watering: When entering the fruit setting period, the plant needs sufficient nutrients and water. It should be combined with irrigation to carry out thin fertilizer application to meet the needs of rapid growth and development of black tomato plants and fruits.
Preserved fruit and preserved fruit: Black tomato flower vibrating and pollination can be used and the fruit is controlled. The concentration is controlled at 10mg/kg flowering period to control irrigation and foliar spray fertilizer. The management of fertilizer and water during the ripening period of the fruit should be evenly dried to prevent cracking. The lateral branches are prone to occur between the leaves and the leaves must be pruned frequently and in time.
Yield per plant: Under normal conditions of temperature control and field management, fruit can be continuously harvested for 4-8 months, and the yield per plant is generally 3-5 kg. When the management is good, the yield per plant can reach more than 10 kg.
Fruit harvesting: Open black tomatoes can be harvested in about 60 days after planting. Storage or long-distance transportation is best harvested during the color change or semi-ripe period. Fresh fruit is best harvested in the near maturity period. Early harvesting at an appropriate time can increase the yield and output value of the early stage, and is conducive to the growth and development of the upper ear of the plant.
