For farmers, planting leeks can be "once and for all", so what are the main points of planting leeks?
1, soil: You don't need to choose a good place to grow leeks, as long as the pH value is 5.5-6.5. 2. Temperature: The germination temperature of leek seeds is 12-18, and the temperature after germination is only 15 -24. 3, lighting: as long as the illumination is moderate. Excessive light will reduce the quality of leeks; The light is too low, the tillers are few, and the yield is reduced. 4. Moisture: The air humidity in the leek planting area should be 60-65%, and the soil humidity should be 70-80% of the field capacity.

There is also local adaptability: leek germination temperature 15-20 degrees, minimum temperature 0-4 degrees, maximum temperature 25 degrees, suitable growth temperature of leek 15-24 degrees, which is suitable for planting in most parts of the year. There is no requirement for soil, as long as the drainage is good. In areas with poor drainage or stagnant water, leek roots are prone to rot, and leaves turn yellow, dwarf, tiller decrease and even die.

From the first day of planting leeks, we must first tell leeks that as leeks, this life is to grow taller and don't think about anything else. Remember to turn over the whole place every two or three years. The temperature in autumn is getting lower and lower, which is beneficial to the growth of leeks. Before leek grows rapidly, it should be topdressed once and sprayed with a new high-fat film to improve fertilizer efficiency and prevent the spread of germs. When topdressing, leeks should be pushed from row to row with bamboo poles, exposed from the ground between rows, ditched, covered with bean cakes, and then covered with soil. After fertilization, water it once. You can also water the leeks first. When the boundary is suitable, divide the leek from the row to both sides with a bamboo pole, spread the bean cake between the rows, then hoe it and mix the bean cake with the soil. Water every 5-7 days 1 time.
