The farmer Zheng Lun recently planted the field crops, but after planting it for so long, he did not make money. Seeing that others planted greenhouses made money, Zheng Lun also wanted to try to grow vegetables. Under the guidance of the town's agricultural stores, the greenhouse was built.
According to Zheng Lun’s expectations, the greenhouse was built, and it would be no problem to make money back within two years. When the greenhouse was built, it was busy to buy seedlings and planted cucumbers.
However, things were not as smooth as I thought. After the greenhouse was built, everything was implemented in accordance with the management guidelines of fertilizing and fighting drugs.
Cucumbers are really slow, and the seedlings are still weak. Zheng Lun suspected that it was a disease, he was busy playing with fungicides, but the cucumber not only did not improve, but slowly the leaves turned yellow, and finally many died.
This is a big blow to Zheng Lun, but I can't find the cause of the disease. Finally, there is no way, please come to the agronomist in the county to help, the teacher into the shed to see it, greedy small and cheap to eat big losses.
When Zheng Lun built the greenhouse, he bought a very cheap plastic film. After it was built, it was planted without ventilation. The film produced some volatile substances such as ethylene, diisobutyl phthalate and chlorine.
They can enter the leaf tissue through the stomata on the leaves of the cucumber, destroying the chloroplast of the leaves, causing the slow growth or even death of the cucumber, which has a great influence on the yield of cucumber.
When this happens, it is useless to use fungicides. It should be applied to foliar fertilizers such as Hartz xylan or chitosan oligosaccharides. Attention should be paid to ventilation while spraying, so that this phenomenon can be solved very well. . Therefore, in terms of planting crops, we must not be greedy and cheap, and we must not blindly follow the trend. Being down to earth and accumulating experience is the last word.
