Four key points of planting leek

The tillering ability of leek is very strong, and there is a phenomenon of root jumping (that is, with the gradual upward movement of the tiller of leek, the rooting position of leek is also rising), so sustained growth will often lead to a significant decrease in yield and quality after three or four years of planting leek. Vegetable farmers must replant leek in order to ensure high quality and high yield. So, how can we ensure that leeks continue to grow and last for more years? For this reason, the reporter successively went to the pioneer camp of the white leek planting professional village and the green leek planting professional village Wenjia village in the Wenjia street of Shouguang City to see how they grow leeks.

Reasonably determine the distance between leek beds according to Xu Guang, a vegetable farmer in Wenjia Street of Shouguang City, Xu Guang told reporters that because the production process of white leek and green leek is different in winter, that is, white leek needs to be covered with soil, while green leek does not need to be covered with soil, so the distance between the two kinds of leek border is also different. For example, green chives do not need to be covered with soil in winter production, but only need to set aside a place for wind barrier and walking operation, so the distance between leek beds is about 0.8 meters. On the other hand, white leek needs to take soil from the front of the leek bed in winter, and the amount of soil is relatively large, so in addition to setting aside a wind barrier between the two leek beds, it is also necessary to set aside a convenient place for soil collection, so the width between the leek beds should be large, and the distance between the two leek beds should be about 1.6 meters. Scientific close planting to extend the planting years of leek reporter in Shouguang City Wenjia street interview, many vegetable farmers reflected to the reporter, leek planting is too dense, although can quickly achieve high yield, but also easy because leek tiller too fast, resulting in leek yield and quality decreased rapidly in about 3 years of planting, vegetable farmers have to re-seedling renewal, laborious and laborious, so we should pay attention to reasonable close planting. When planting leeks, vegetable farmers generally plant 30-40 leeks according to two-meter-long ridges with a row spacing of about 28 cm, which can prolong the renewal life of leeks and help to make leeks grow stout and of good quality. Because leek tillers most rapidly in the first year after planting, so if the leek planted in that year is used to produce white leek, the yield per ridge can reach about 5 jin, and the yield can reach about 8 jin in the second year, and can be maintained for 3 years. If vegetable farmers plant about 50 leeks according to two-meter-long ridges, although they can achieve a yield of about 6 jin per ridge when producing white leeks that year, the high yield period of leeks can only last for 2 years, which is not conducive to the improvement of leek production and efficiency in the long run. Therefore, vegetable farmers must pay attention to the planting density when planting leek. The reasonable study on the planting depth shows that the deeper the Chinese chive is planted, the weaker the tillering ability is, the slower the root jumping is, and the planting is too shallow, the tillering ability of the leek is strong, and the root jumping occurs quickly, which will soon cause the root system of the leek to grow above the ground. affect the planting and use life of leek. According to Shouguang City Wenjia Street vegetable farmer Sang Peimin told reporters that the general leek planting depth of 5-6 cm is the most appropriate. This planting depth not only does not affect the tillering of the plant, but also prevents the root jumping of the plant from causing the planting life to be too short, and the renewal life of the leek border is extended to about 5 years. Newly planted leek cannot leave leek moss in order to ensure the yield of leek and promote the expansion and tillering of pseudostem, so we should pay attention to inhibit the reproductive growth of plant, promote the vegetative growth of plant, and remove the newly grown leek moss in time, so as to ensure that the nutrients produced by leaves are concentrated to supply the expansion of leek pseudostem, and lay the foundation for high quality and high yield in winter.
