Lao Chen has been planting for many years. The problem of cucumbers grown in greenhouses this year can be difficult for him. It turns out that he used to plant pear trees in greenhouses. The pear trees have passed the fruitful period and they are not making money. Cut the tree, he saw that other people grow vegetables and make money, just think that they can also try to plant them, and then planted cucumbers after changing the previous three acres of greenhouses.
Because there is no experience in planting in the first year, the small problem of cucumber is always constant. People in the village ask and ask, he is embarrassed, but now the cucumber has been planted for more than a month now, it is not Long, he has no way, just come to our platform to consult and see what to do.
When I saw it in the shed of Lao Chen, he found that the cucumber seedlings had not been long, and the growth point was level with the leaves. Normally, the growth point should be about 5 cm higher than the leaves. It is obvious that this is the plant's resistance to stress. Poorly caused.
How to solve the poor resistance of greenhouse seedlings?
The first is to strengthen management, and then increase the temperature, especially the ground temperature. On the one hand, it can spray some anti-reverse agents to improve the resistance of the plants to the ground temperature, stimulate the growth of the seedlings, and use the pure bio-extracted bio-stimulating hormone 600 times + The organic carbon is used 300 times, plus one piece, sprayed once every 15 days, the plant's resistance to stress is raised as much as possible, and the growth is slowly restored.
In addition, the North China region should not be topdressed in January, the ground temperature in the shed is relatively low, and the topdressing can not be absorbed. In the case of low temperature, too much NPK is easy to burn, and 8 mu of organic carbon can be used in one mu of land. Stimulate the roots, put this month to the past, try to pick melons at the beginning of February, and enter the fruiting period in the middle. At this time, the price is not too low, and it can save a little benefit.
After listening to Chen, I did it according to this method. If you have any other good methods or ideas, you can leave a message below, and welcome everyone to actively discuss and communicate.
