Today we went to visit a vegetable base, and the farmers said that the growing condition of the crops planted was not ideal. After entering the greenhouse,felt that there was no problem in temperature, the water was the same, even the fertilizer used was similar. However, some crops were growing well, while some were obviously not. The biggest problem is that there are so many different kinds of crops and vegetables in one greenhouse.
Be aware that different crops have different temperature requirements, and that even warm-loving crops may not have the same optimum temperature for their respective growth. Today, Huazhen Agriculture will take the most common tomato, eggplant and pepper in the big greenhouse to talk about this problem!
1. Tomatoes are warm-loving but not heat-resistant
The appropriate temperature for growth is 13-28℃, and the minimum temperature in seedling stage should not be lower than 13℃ or higher than 33℃, otherwise the differentiation of flower buds will be affected. Temperatures below 15℃ grow slowly and fail to flower or pollinate poorly. 25℃ in the daytime and 17℃ at night is the best flowering period. The fruit stage is 25-28℃ in the daytime and 16-20℃ at night. 19-24℃ is conducive to the formation of lycopene, lower than 15℃ or higher than 30℃ is not conducive to the formation of lycopene.
Although tomato is warm-loving, it can not heat-resistant. Above 35℃, it affects flowering and bearing. Growth stopped at 40℃; The temperature is 42℃ and the air humidity is below 50%, may burn the seedlings.
2. Eggplant is warm-loving and heat-resistant
The optimum temperature for eggplant seed germination was 28-30℃. The minimum temperature at seedling stage should not be lower than 15℃ or higher than 33℃, otherwise the differentiation of flower buds will be affected. 25℃ in the daytime and 17℃ at night is the best flowering period. The suitable temperature for growth is about 25℃, the growth is slow below 20℃, and the growth basically stops below 15℃.
3. Peppers like warmth
Seed germination suitable temperature is 15-30℃, the most suitable for 25℃, in this temperature, 3-5 days can be out of the seedlings; The minimum temperature of flowering period is 10℃, otherwise it can not be pollinated; The suitable temperature for fruit development and color turning was 20-30 ℃. Pepper colonization can be carried out only when the ground temperature is stable through 10℃.
Do you see that? Tomatoes,pepper,eggplants grow at different temperature,do not mix in a greenhouse!
