If you plant a short scallion, it's a variety problem; if it's a long scallion, it's a planting management problem, which may be caused by flat-wa planting or ridge planting, but the green onion is not raised too high or shallow.
We Gansu people often joke that "potato (potato) grows up, but it is not big". Although it is a joke, it reflects from the side the farmers' habit and importance that underground root and stem crops must be cultivated and ridged. Similarly, in the production management of green onion planting, it is also necessary to make topdressing and ridging for two or three times.
According to the seasonal solar terms at that time, the remedy can come urgently, because after autumn, the temperature gradually drops, and the scallion officially enters the formation period of scallion. At this time, it is timely combined with watering and topdressing to cultivate the soil, and then combined with weeding and loosening the soil, the soil is cultivated again after 15 days. According to the depth of transplanting, the top soil is finally added to the height of 30 to 40 cm.
In a word, in order to avoid shallow scallion planting, it is necessary to ditch and transplant. Combined with watering and topdressing, weeding and loosening the soil, it is necessary to carry out several times of ridging (ridging) and heightening the ridge surface. Only in this way can a moist, loose and dark good growth environment be created for scallion, and the scallion can grow long and thick, with high yield and great benefits.
The above is my practical experience in planting green onions for your reference! However, there are planting habits in various places. What about our good experience of being long and thick? Hope to share and communicate!
