Let's grow tomatoes this season
How to grow zero to one hundred greenhouse tomatoes: Greenhouse tomatoes are another profitable greenhouse product that most greenhouse owners welcome. People use tomato fruit all year round. By growing tomatoes in the greenhouse, you can produce more products per square meter and increase your income in this way. Stay with us until the end of this article.
Greenhouse tomato cultivation
The scientific name of tomato is L. lycopersicom or Lycopersicom esculentum. Tomato is one of the plants of the Solanaceae family. The origin of this plant is South America and includes the regions of Mexico, Ecuador, Peru and Chile.
Stages of tomato growth
The greenhouse tomato growth stages are divided into five stages:
Early growth before germination and root formation
Seedling growth until transferring the seedling to a new environment
Vegetative growth until the first flowers bloom
Early fruiting from the opening of the first flower to picking the first fruit
favorable environmental conditions
Temperature conditions of greenhouse tomatoes
Greenhouse tomato is one of the hot season products and is sensitive to cold. Tomato fruit is more sensitive to cold than its leaves. The area where this greenhouse product is grown must have warm weather for at least 4 months.
This product needs an optimal daily temperature of 25-30 degrees for vegetative and reproductive growth and 16-20 degrees at night. The ideal temperature for greenhouse tomato fruiting is 18-24 degrees Celsius. But temperatures below 15 and 30 degrees are weak for tomato fruiting. The number of degree-days for fruit ripening from planting to harvesting is about 3000-4000.
Light requirements of the tomato plant
The light intensity required by the plant in the greenhouse is 400-500 micromol/m2/s or 22000-27000 lux or 89-111 W/m2 or 2-30 mol/m2 per day. It reaches the light saturation point at 13 megajoules per square meter per day.
The amount of carbon dioxide
The amount of carbon dioxide required for maximum performance is about 1000 ppm and in amounts greater than 1000 ppm, it shows signs of poisoning.
Characteristics of suitable soil for greenhouse tomatoes
Greenhouse tomato needs adequate drainage especially after the germination stage and shows sensitivity to waterlogging when it reaches fruit. Excessive moisture causes the death of seedlings caused by Phytophtera, Pythium and Rhizoctonia fungi.
Because tomato has a root structure with branched fibrous root ends, aeration and loosening of the soil texture are necessary for the growth of the plant with high yield. Although the roots penetrate up to 60 cm in the soil, but 70% of the roots are located at a depth of 20 cm.
