The four points of leeks colonization
The ability of the leeks to deliver is very strong, and there is the phenomenon of rooting (that is, with the hierarchies of leeks gradually moving up, and the rooting position of leeks is also rising). This continuous growth will often result in the yield and quality of leeks colonization after three or four years. With drastic reduction, vegetable growers must re-plant leeks so as to ensure high quality and high yields. So, how can we ensure the continued growth of leek and continue for more years? To this end, the reporter successively visited the pioneer village of the white leeks planting village of Wenjiao Street in Shouguang City and the village of Wenjiao, a specialty of Qingcai Vegetable Cultivation, to see how they planted leeks.
Reasonably determine the spacing
According to reporter Xuan Guo, a vegetable farmer at Wenjia Street in Shouguang City, told the reporter that because the production process of white leeks and green leeks in winter is different, that is, white leeks need to be covered during production, while green leeks need not cover soil, so the two kinds of leeks The spacing between the jaws is different.
Like green amaranth, because in the winter production does not need to cover the soil, but as long as the place where the wind barrier and the place to walk can be set, so the distance between the crucible can be about 0.8 meters. The white leeks, because in the winter, they need to get the soil from the front of the pupa and get a large amount of soil, so that in addition to the place where the wind barrier is reserved between the two pods, it is necessary to make it easy to access. In the place of soil, so the width between the poles should be large. Generally, the distance between the two poles is about 1.6 meters.
Scientifically planting and extending the cultivation period of leeks
The reporter interviewed reporters at the Wenjia Street in Shouguang City. Many vegetable farmers reported to reporters that the leek was planted densely during planting. Although it could quickly achieve high yields, it was also very easy to deliver the leek because of excessive delivery, resulting in yield and quality of the leek. In the year or so, they quickly reduced. The vegetable grower had to renew the seedlings to update them, which was labor-intensive. Therefore, it is necessary to pay attention to reasonable and close planting when planting.
When planting leeks, farmers usually plant 30-40 trees with a length of two meters long, with a spacing of about 28 centimeters, which can extend the renewal period of leeks, and help the leeks grow stout and of good quality. Because leeks are most rapidly delivered in the first year after planting, the leeks planted in that year, if used for the production of white leeks, can reach a yield of about 5 pounds per ridge, and can reach about 8 pounds by the second year. Yield, and can maintain for 3 years. If a vegetable farmer grows about 50 trees in a two-meter-long ridge, although the production of white leeks is about 6 kilos per ridge at that time, the high yield period of leeks only lasts for 2 years. This is not good in the long run. Leek production and efficiency increase. Therefore, vegetable farmers must pay attention to planting density when planting leeks.
The depth of planting should be reasonable
Research shows that the deeper the leeks colonization, the weaker the ability to deliver, the slower rooting, the shallower colonization, the strong ability of the leeks, and the quicker rooting, will quickly cause the root of the leeks to grow above the ground, affecting the leeks. Planting life. According to reporter Sang Peimin, a vegetable farmer at the Wenjiao Street in Shouguang City, a reporter said that the depth of colonization of common leeks is 5-6 cm.
This depth of planting will not affect the planting of the plant, but also prevent the rooting of the plant and cause the planting period to be too short. This will extend the rejuvenation period of the plant to about 5 years.
Newly planted leeks must not leave leeks
In order to ensure the yield of leeks and promote the expansion and delivery of pseudo-stems, it is necessary to pay attention to inhibiting the reproductive growth of plants and promote the vegetative growth of plants. Attention should be paid to the timely removal of newly grown Brassica oleracea in time to ensure the nutrients produced by the leaves. Concentrated supply of pseudo stems of leek enlargement, laying the foundation for high quality and high yield in winter.
