Although the height of the tomato plant is not short, it can be protected from lodging by the help of a support, so you can also try vertical planting.
She originally chose tomatoes and spinach. Both of these vegetables can be grown on planting racks, are relatively nutritious, and contain vitamin C.
Now I prefer spinach.
Mainly because spinach is more cold-resistant.
Although there is a greenhouse, how much resources are needed to raise the temperature of the greenhouse to 25 degrees, which is suitable for the growth of tomatoes, at minus 40 degrees Celsius? Spinach is different. It is extremely cold-resistant and can germinate at 4 degrees Celsius. The suitable temperature is also 15 degrees Celsius.
There is also the issue of light. Tomatoes need more light, otherwise the nutrition of the fruit will be directly affected, which is also energy consumption.
Tomatoes are also more laborious to grow, as artificial pollination is required to increase fruit set rates.
Spinach can be harvested all year round with simple management, and if you are fast, you can have a harvest in 35 days.
So after weighing the pros and cons, Qiao Xuejun chose spinach. However, you can also set aside one acre of land to grow something else.
You can try tomatoes and strawberries.
With a greenhouse, we can also try to breed excellent cold-resistant hybrids. It would be even better if we could breed crop seeds suitable for the current climate.
She had wanted to do this for a long time, and she often went out to look for plants in the wild because of this, hoping to find crops with cold-resistant genes to cross with existing high-yield crops. But her luck didn't seem to be very good at the moment, and she only collected purple flowers and rye.
It would be impossible to achieve this goal relying solely on the seeds she had now.
That requires a very strong germplasm resource.
——Zhao Xian’s seed bank.
And Zhao Xian was about to enter the city.
