How many stubbles can be harvested in a year for growing leeks? How to manage the first crop after h

Leeks are resistant to low temperature and drought, wide applicability to ambient temperature, spring, summer and autumn can be produced and manufactured, leeks are shrunken rhizome crops, rhizome heading and regrowth level is rich and strong, many stubbles can be harvested in a year, but the actual number of stubbles also needs to be determined according to the plant rise, soil organic matter and its market demand, such as commercial leeks, because of its leek leaves are spacious, the leaves are emerald green, the leeks are thick, and the relative height is uniform, and the regulations on the product are stricter, so the frequency of harvesting is particularly small, Too often to harvest seeds.

The accumulation of leek nutrients consumes a lot, which will weaken the regeneration ability of leeks and decline in quality, so in order to ensure the quality and quantity of leeks on sale, leeks are generally harvested 3 or 4 times. Leeks only need to grow new leaves and stems before they can be harvested. Actually, this behavior is not right.

Leeks can harvest a few stubbles, all of which are determined by the rhizome. If the seeds are harvested frequently, it will not only reduce the value of the leeks in the stubble, but also not help the leeks rhizomes absorb nutrients, and it is not conducive to the growth and development of leeks. In hot weather, leeks go into a transient semi-dormant mode.

To alleviate the growth and development, the leaf peptide soft crawls on the road, in the case of we do not do the harvesting work, because, at the moment into the semi-sleeping state of leeks, the nutrients in the leaves and stems are transported to the rhizome and underground stems and rhizomes for storage, and the taste is not very good. In addition, there is another reason why leeks are not harvested in summer, the fundamental reason is that the ambient temperature in summer is relatively high, the precipitation is more, and the time period of high temperature and high humidity is very easy to breed diseases.

In this way, it is very easy for diseases to take advantage of the weakness and cause leeks to be susceptible to pests and diseases. The autumn of September, is the autumn breeze is cool, into the "leek leek Buddha open mouth" season, at this time through a summer root to strengthen the roots, cut off the old leeks, sprout out of the leeks fresh, for wrapping leek small box is very delicious. Before the beginning of winter, according to the frequency of harvesting every 20 to 25 days, it can also be cut two or three times.

When growing leeks, you can harvest at least three crops a year. After the first inspection, you should keep plenty of moisture and try not to cut the second cut in a short time.

Leeks can be harvested countless times a year, once every week, and after the first harvest, you need to water more and rest for a week.

Generally, leeks grown in the northern region of our country can be harvested 3 to 4 stubbles a year, and if they are vegetables grown in the southern region or greenhouses, the number of harvests in a year is more.

3-4 months is fine. In order to promote the growth of leek seedlings, the leek seedlings are generally about 12 15 cm high, combined with watering and secondary fertilizer.

The height of leek seedlings grows to 18-20 cm, which is the appropriate period for leek planting. Before planting, a large amount of well-rotted organic fertilizer should be applied in the planting ground to create a better living environment for the growth of leeks. Apply imported water-soluble fertilizer per mu, use sprinkling, ploughing into the soil, level the land according to the cultivation method for furrow or open planting ditch, furrow, ditch and then apply high-quality farm fertilizer, fertilizer and soil mixed evenly can be planted.

After planting, the leeks go through the hot summer and enter the cool autumn. At this time, it is the most suitable growth stage for leeks, and it is a critical period for fertilizer and water management, and timely fertilization to promote leaf growth has laid a material foundation for the expansion of rhizomes and root growth of leeks. The overwintering ability of leeks and the growth of the next year mainly depend on the amount of nutrients accumulated by the plants before winter, and the accumulation of nutrients is determined by the growth status in autumn, so we should pay attention to the fertilizer and water management at this stage.

Generally, it is necessary to chase 2 or 3 times of Ribery Yanwo water-soluble fertilizer.

Leeks are perennial herbaceous plants, generally speaking, heavy stubble will not affect the growth and development of leeks, of course, the premise is that the land should have enough ability to cope with the growth of leeks, the selected soil should be fertile enough, and it is best to add some Bika granular fertilizer or rotten farmhouse fertilizer base fertilizer.

The harvest of leeks is not based on a few leaves, but mainly on the height of the plant. The height of the leek plant reaches 30-40 cm, and the number of leaves reaches 5-7 pieces, which is suitable for cutting, and the content of various nutrients in the plant is the highest at this time, and the quality and yield are in an excellent state. Generally, 4-6 leaves are most suitable for harvesting when the plant height is 30-40cm.

It can be harvested when the number of leaves reaches 5 to 7 leaves.

The last crop of leeks of the year should be harvested in late winter and early spring. Because the quality of leeks is the best at this time.

In addition, the first leeks are usually harvested on New Year's Day or mid-January, and then every 30 days or so.

In winter, the best harvesting time interval of greenhouse leeks is 30-40 days, at this time, the height of leek plants is generally 30-40 cm, the number of leaves reaches 5-7, the content of various nutrients in the plant is also relatively high, and the quality and yield are in the best state.

The harvest was too early, the overall height and nutrient accumulation of the plants were not sufficient, the yield was low, and the flavor was weak. If the harvest is too late, the plants are prone to lodging, the old leaves are easy to yellow, the risk of infection and disease increases, and the taste tends to decline. When diseases such as gray mold occur in the field, if the plant height has exceeded 25 cm, early harvesting can be carried out considering various factors, which is conducive to disease prevention and control and maintaining a relatively stable overall yield.

The number of harvests should be determined according to the growth of plants, field water and fertilizer, the occurrence of pests and diseases, and market demand. Northern regions in general.

Harvesting should be stopped in mid-April, and the roots should be raised to promote growth and lay the foundation for a bumper harvest in the coming winter.

The last leek of the year, it should be around September, from September to mid-September, this time period is still very good, and then not too close, can be increased by about five centimeters, this is the best,

The last crop of leeks in the year is usually in autumn, about after the Chung Yeung Festival, which is conducive to the growth of leeks.

In fact, as long as the local temperature is not too cold, then the leeks can be passed all year round, if the weather is relatively cold, then it is necessary to end the last leeks before the frost, because the big double is serious, the leeks will freeze to death, so it is necessary to cut the last batch of leeks before hitting again, and then do a good job of antifreeze treatment.

When planting white onions, cut the last crop of leeks, and the northeast ones are cut around the beginning to mid-September.

If the last crop of leeks of the year is cut at the end of October. Because the weather will freeze after the end of October, the leeks should be pressed with something to keep warm, and the spring will grow during the day.

The last leeks of the year need to be harvested before the frost falls, try to get a few days in advance to allow the leeks to grow longer.

Leeks as a root plant, planted once, can be harvested for several years in a row, and the planting is simple and easy, very popular with everyone, leeks taste fresh and tender, spicy taste makes many people want to stop, about leeks like people think that leeks are the most delicious delicious, and about the taste of leeks, but think that the taste of leeks is too unpleasant, leeks can continue to grow after harvesting, the harvest cycle is very long, can be harvested for several years, such a growth habit is also called by everyone: lazy vegetables, Leeks are not only planted in farmland, vegetable gardens, but even urban balconies, everyone also likes to use flower pot containers to grow leeks, which can be eaten and cut freshly with a novel taste.

Leeks can be harvested five to six times a year under normal conditions, but the demand for leeks should be well managed

1. Leeks are fertilizer-loving, when planting leeks, we must put down the bottom fertilizer, the bottom fertilizer can be used with well-rotted farmhouse fertilizer at home, and it is best to use well-rotted chicken cage manure to cushion the bottom, so that it can play a long time of fertility.

2. Leeks can withstand high temperature and cold, but leeks can not be drought, and the growth of leeks will be sluggish after drought, and the leaves will turn yellow, so the leek seedbed should insist on soil moisture, so as to ensure the normal growth of leeks.

3. In the growth process of leeks, fertilizer should be added according to the growth of leek leaves, which can be watered with manure or urea water, so that leeks can grow rapidly.

4. After harvesting leeks, the leek field should be sprinkled with plant ash, which can avoid leek incision infection, kill leek maggots in the field, and supplement the potassium fertilizer of leeks, so that leeks can sprout and grow quickly.

In addition to fertilizer and water management after leeks are harvested, it is necessary to stop hoeing in a timely manner, protect moisture, prevent pests and diseases, leeks love to breed maggots, can use drugs to stop irrigation root treatment, reduce the onset of pests and diseases, conducive to the growth of leeks, leeks are the most delicious is after winter, stop harvesting the head knife leek, also known as the four fresh: toon sprouts, falling lotus root, top flower cucumber head knife leek, the taste is the richest, and the most tender, there will be no residue in the mouth to eat, leek open field planting and greenhouse planting, The number of harvests is also different.

About two to four times a year, the adaptability of leeks is very strong, after harvesting, we must ensure soil fertility, and then we must remove all the clods or stones in the soil, sprinkle grass and wood ash, loosen the soil and weed, increase the air permeability of the soil, and then fertilize and water.

The planted leeks can generally be harvested about 10 times a year; After harvesting, the first thing to do is weeding, loosening the soil, proper fertilization, and watering, and wait until the leeks grow another three to five centimeters before they can be harvested again.

Under normal circumstances, leeks can be harvested five or six times a year, after harvesting, more watering, more fertilization, the temperature should be suitable, there should be a certain amount of heat, and the soil can be managed very well.

Leeks have strong bifurcation, and when they grow to about 15 cm, they can be cut for the first time.

The first watering must be watered thoroughly: the leek seeds are generally planted in early March of the lunar calendar, some organic fertilizers and grass ash can be properly applied, and the next few days can be watered depending on the dryness of the soil.

Harvesting is based on growth conditions and can be harvested 5-6 times a year, 25-30 days apart.

The height of the harvest should be cut to the yellow leaf sheath of 3cm on the bulb.

After harvesting, the bark is watered and topdressed in time to promote the growth of roots and leaves.
