What is the suitable growing environment for tomatoes? What are the precautions when planting?

First, the suitable growth environment for tomatoes

1, temperature

? Tomatoes are warm-loving vegetables, which are neither cold nor heat-resistant. The suitable temperature range for growth and development is 10-33℃, and the optimum growth temperature is 20-25℃. When the temperature is lower than 10℃ or higher than 33℃, the growth and development of plants are slow. When the temperature is lower than 5℃ or higher than 40℃, the plants stop growing. When the temperature is lower than 0℃ or higher than 45℃, plants will be damaged and die soon.

lamplight

Tomato is a light-proof crop, but there is no strict requirement on photoperiod. Under the sunshine of 1 1- 13 hours, tomato plants grew vigorously and blossomed earlier. Although the length of photoperiod is not an important factor in tomato development, light intensity is directly related to yield and quality. Insufficient light can easily lead to plant growth too long, malnutrition, reduced flowering period, abnormal flower development, and lead to flower drop; Excessive light can also cause plants to be easily infected with viral diseases, or lead to premature aging of stems and leaves, and fruits are easily burned.

Step 3: Moisture

? Tomato has developed root system, strong water absorption, lush stems and leaves, strong transpiration and high fruit water content. They are semi-drought-tolerant vegetables and need high water content. Therefore, although tomatoes need to absorb a lot of water from the soil, they do not need regular irrigation.

4. Soil and nutrition

? Tomatoes have strong adaptability to soil, so the requirements for soil conditions are not high. Except for low-lying, waterlogged and poorly drained land, it can be planted in other places, but fertile loam with deep soil layer, good drainage and rich organic matter is the most suitable. The optimum soil pH should be 6-7.

Second, the precautions for planting tomatoes

1. After the seedlings are picked, we should concentrate on the management of tomatoes. If the weather is hot or the land is dry, water it in time. If it is serious, it needs spraying. At this time, we must strictly follow the instructions of the drug and observe the spraying ratio of the drug.

2. During the growth of tomatoes, chemical fertilizers should also be applied. When tomatoes turn white, add an extra fertilizer, which can speed up the growth of tomatoes and make them grow better, bigger and more ruddy.

3. It's best to put the tomatoes in advance before the fruits, so as to ensure that the tomatoes won't touch the soil and rot. In addition, if the sunshine is insufficient, it is best to cut off some leaves, which can solve the problem of insufficient sunshine and reduce the waste of fertilizer.
