The growers want to have a good harvest of their crops. The grown onion grower Zheng Shu has been planting green onions for three years, and it is also a local one. Zheng Shu planted 8 acres of green onions this year. In the past year, the output of one mu was 6000-8000 kg, which is already very good!
However, this year, Zheng Shu planted a stalk of green onions and produced tens of thousands of pounds, and caught up with the wild onions to raise prices. This year, an acre earned more than 20,000 pieces.
If you want to break through tens of thousands of pounds, I am afraid that every grower wants to break his head! Zheng Shu said that it is not so difficult to have high yields. It is not difficult to grasp the planting points of these key periods. Let's share it with you:
First, the selection of breeding links
Try to choose the seeds of the formal channels, the loss of the seeds is not right. Must be well grasped when sowing, the north is planted in Bailu, too early to cause the green onions to convulsion, too late, the green onions are weak and unfavorable. At the same time, the seeding density must be appropriate, especially not too dense to cause a lot of high seedlings.
Second, the planting link
The line spacing is best controlled at around 80 cm. It is necessary to pay attention to the combination of organic fertilizer and chemical fertilizer to avoid partial application of chemical fertilizer. In addition, attention should be paid to the application of biological bacterial fertilizer and trace elements, which can not only increase the yield, but also increase the disease resistance of the onion and improve the quality of the onion.
Third, anti-floating work
The growth of green onions is faster in the middle and late stages. At this time, it is necessary to prevent the lodging. By chasing calcium fertilizer, increase the lodging resistance of the onion itself, the whole growth cycle of the onion should pay special attention to the application of calcium fertilizer. If the calcium is deficient, the onion stem is too soft and it is easy to fall.
Through the above methods, Zheng Shu's green onion production has made a good breakthrough, and also hopes that all the farmers' friends of the green onion growers have a good harvest.
