What are the biological characteristics of tomatoes?
First of all, the root system of tomato is relatively strong, widely distributed and deeply rooted, and its regeneration ability is also very strong. It is easy to have adventitious roots on the stem nodes, so it is easy to survive. The stem can stand upright in the early stage, but it needs to stand upright in the later stage. Leaf molecular leaves and true leaves can secrete juice with special smell, so there are few pests.
What are the stages of tomatoes?
Germination period: it usually takes 6-9 days at room temperature from sowing to the appearance of the first true leaf, during which nutrients are supplied by the seeds themselves. Seedling stage: Generally, the seedling stage is from the appearance of the first true leaf to the appearance of the first flower bud, which is generally 45-50 days. This stage is the transition stage of tomato from vegetative growth to reproductive growth and vegetative growth, which directly affects the yield.
Flowering and fruit-setting period: generally, it takes about 15-30 days from inflorescence to first fruit formation. Generally, at this stage, fruit and seedlings grow together, which is the key to solve the contradiction between vegetative growth and reproductive growth.
Fruiting period: it takes about 40-60 days from the inflorescence to the end of harvest. Generally, the vegetative growth is also very vigorous in this period, which is manifested by the increase of plants and leaves. Therefore, at this stage, we should properly handle the relationship between vegetative growth and reproductive growth, strengthen trees, and avoid the influence of virtual growth on flowering and fruiting.
What is the water requirement of tomatoes?
The transpiration of tomato stems and leaves on the ground is very strong, and the transpiration coefficient is generally around 800, which requires more water, but the root system of tomato is very developed and its water absorption capacity is relatively high.
Remarks:
1, planting container: the container can be deeper (it is best to have a drain hole at the bottom);
2, nutrient soil: you can buy nutrient soil suitable for growing tomatoes directly online (some will be mixed with base fertilizer), or you can do it yourself.
3, seedlings or seeds: there are many varieties of tomatoes, and they are also divided into sizes. If you mainly want to use them as fruits and vegetables, you can choose big tomatoes; If you mainly want to pick it as fruit to eat, you can choose some varieties such as cherry tomatoes and small tomatoes, and the planting methods are basically the same.
4. Common pests and diseases: Viral diseases, bacterial wilt, cotton bollworm, aphids and other pests may occur. If it appears, check whether it is caused by these pests, and then solve it in a targeted manner.
