Growing environment and local conditions of tomatoes

growing environment and conditions of tomatoes

tomatoes are cultivated in large greenhouses, plastic greenhouses and other facilities in Europe, America, China, Japan and other countries. They are widely cultivated fruits and vegetables, with the United States, the former Soviet Union, Italy and China as the main producers.

Growth conditions of tomatoes

Tomatoes have strong adaptability to the environment and do not choose soil, but they are suitable for planting in loam with deep and fertile soil layer, good drainage and rich organic matter. The pH value is preferably between 6 and 7. They like sunny and well-ventilated environment, but they need shade in summer. They like humidity, the soil humidity should be around 7%, and the air humidity should be around 45%.

growth temperature of tomatoes

tomatoes like warm growth environment, but they are not cold-resistant. Generally, the optimum temperature for assimilation is 2~25 degrees, and the optimum soil temperature for root growth is 2~22 degrees.

Growth process of tomatoes

Tomatoes have two planting times, mainly from February to May and from July to September. The weather conditions in these two periods are good, very warm and the light intensity is not high, which is very suitable for seedling growth. 1. Germination period: After planting and sowing tomatoes, water them in time to keep the soil moist. Seeds can germinate normally after absorbing water. When 3-4 true leaves grow, the growth and development of tomato will enter seedling stage from germination stage. 2. Seedling stage: the seedling stage is from the true leaf stage to the budding stage, and the tomato changes from heterotrophic to autotrophic. The reason for the rapid change is root growth, and the relationship between root and shoot growth at seedling stage will be different among different varieties. Early-maturing varieties take root quickly before flower bud differentiation, and late-maturing varieties will quickly surpass early-maturing varieties after flower bud differentiation. 3. Flowering period: The period from germination to the formation of the first fruit is the flowering period of tomato. After planting, it takes half a month to a month from germination to flowering. The time of early-maturing varieties is shorter, and the cultivation time of medium-maturing varieties or low-temperature maintenance varieties is longer. 4. Fruiting period: the period from the first inflorescence to the end of fruit ripening and harvesting is the fruiting period. It can grow indefinitely. As long as the environmental conditions are suitable, the fruiting period can be extended indefinitely, just because the price of open-field tomatoes will drop when they enter the peak yield period.
