When is the last crop of leeks of the year to be cut?

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.

The last crop of leeks of the year should be harvested in late winter and early spring.

First, leek maintenance methods.

1. Temperature: Leeks are suitable for growing in warm places. Specifically, it is more appropriate to keep it at 15 to 25 degrees.

In addition, when breeding, the temperature should not be lower than 12 degrees, otherwise the breeding is easy to fail. In winter, try to keep it slightly warmer as well.

2. Light: Its negative resistance is better, however, in order to promote its growth, it is better to maintain moderate intensity of sunlight. However, when the light is very strong, the quality of the leeks will deteriorate, so it is necessary to block the light slightly.

3. Watering: It is a more moisture-loving variety. The moisture of the soil should be slightly higher, but try not to exceed 80%, and not accumulate water. In addition, the air humidity should also be properly monitored, and it is better to have it at 60% or 70%.

4. Fertilization: Leeks are also a fertilizer-loving plant, and their fertilizer tolerance is also relatively good. Usually, you can pay more attention to fertilization, you can apply water-soluble fertilizer for vines and leaves, and the base fertilizer of the soil can not be less.

Second, breeding skills.

1. Reproduction: It can be sown and reproduced. The most suitable time to plant is between the end of March and the end of April.

Before planting, the seeds need to be soaked and germinated before planting. It can be "spreading". To stop nausea, it is necessary to cover a thin layer of matrix.

After the resurgence, another layer of soil is required. After the soil is covered, it needs to be covered with another layer of mulch. When the seedlings emerge, remove them.

2. Weeding: If it is a large-scale planted leek, then there will be many weeds mixed with it, which should be removed in time. Otherwise, they deplete the limited nutrients in the soil. In addition, after weeding, you can supplement it with a little fertilizer.

3. Problem diagnosis and treatment.

1. Diseases: There are many diseases of leeks. The specific species is "gray mold", which will cause leaf death, and the speed of transmission is relatively fast, and it can be controlled with pesticides. There may also be "epidemics", which are more harmful to stems and leaves, and can be prevented and treated with pesticides.

2. Pests: There are many types of pests, such as "leeks", etc., which are very harmful, and can be irrigated with pesticides.

Northern leeks can generally be harvested until November, and then they can be harvested again in the spring. If it is a greenhouse farming, it can be done all year round. Under normal circumstances, if you harvest every 30 days or so, you can harvest 3-4 times in spring. In summer, the growth rate is slower, and the number of harvests will be less, mainly harvesting leeks or leeks; In autumn, in order to raise roots for winter, it can generally be harvested 1-2 times.

Growth HabitsLeek belongs to the lily family perennial root vegetables, strong adaptability, cold and heat resistance. The suitable growing temperature is between 15 and 25, and the underground part can tolerate lower temperatures. It can accept moderate light intensity and has strong resistance to negatives.

If the light is too weak, the yield will be low, which can easily lead to premature aging. It has strong adaptability to soil texture and is suitable for pH. Leeks have a large demand for fertilizer and have strong fertilizer tolerance.

Generally, leeks are no longer cut in late autumn and early winter. The main purpose is to nourish the roots, so that the nutrients can be transferred to the stems and stored, so as to improve the yield and quality of leeks in the coming year. Although leeks are perennial vegetables that can be harvested many times a year.

However, cutting leeks needs to be determined according to plant growth, soil fertility, etc., so as to make the leek life longer, high yield and high yield. It should be noted that the leeks planted in that year are not suitable for harvesting, and they should be mainly rooted raising.

Leeks are last harvested in late winter and early spring, but the harvesting time varies depending on the cultivation method in each region.

It depends on where you are. If you're in the north, it's a little late, because summer is coming late! If you're in the south, cut a little earlier, because it's hot and you cut leeks when it's hot, that's not okay.

The farther south you go, the sooner you have to stop

It should be before the frost falls, and after the frost, don't cut the leeks anymore, because the low temperature will easily cause the leeks to be injured and die in the winter.

Leeks were last harvested in late winter and early spring, basically in January.

However, due to the different cultivation methods in each region, the harvesting time also varies. For example, if you cultivate in the open field in the northern region, it is suitable to harvest in November, and there is no time limit for greenhouse planting, and leeks can be harvested every January or so, and you can start cutting the leaf sheath 6-7 cm above the bulb when harvesting.

When was the last time leeks were harvested:

1. The last time leeks were harvested was in late winter and early spring, but the cultivation methods in each region are different, so the harvesting time is also different.

2. For example, open field cultivation in the northern region is suitable for harvesting in November, and there is no time limit for greenhouse planting, and leeks can be harvested every 1 month or so, and the leaf sheath at 6-7cm above the bulb can be cut when harvesting.

Methods of harvesting leeks:

Leeks to harvest early in the morning is better, because after a night of growth, the quality is very fresh and tender, leeks should pay attention to the height of stubble when harvesting, to just cut to the bulb on the 3-4cm yellow leaf sheath is appropriate, too shallow yield is reduced, too deep damage to the bulb, easy to affect the growth of the knife and the growth of the whole plant.

This is related to the local climate, and if it is in the north, it will be around November, but in the south, it will not be known. If it is a greenhouse, it can be cut all year round.

Leeks grow very quickly and can be cut many times in winter.

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 planted in the first year can be cut. When harvesting, it can be harvested in a timely manner according to the growth of leeks and the market, and it is generally best to harvest in the morning, so as to cut to the upper part of the bulb 3 4 cm yellow leaf sheath. Leeks planted in greenhouses can be cut three times a year, the first stubble growth period is 30-40 days, and the subsequent growth period of each stubble is about 25 days.

The sowing time of leeks can be divided into three types: spring sowing, summer sowing and autumn sowing

1, spring sowing: should be early but not late, spring when the local temperature is stable at 5-10 can be sown, at this time the ground is not completely cleared, the slurry period is not to the surface is relatively wet, it is easy to emerge, this sowing method also avoids grass damage, because the leek seedlings come out faster after sowing, and the temperature at that time is not suitable for weed germination, forming a time difference. Therefore, it is recommended that everyone try to use this method of sowing.

2. Summer sowing: generally sowing after cucumber and tomato strike, at this time the temperature is high and prone to drought and waterlogging, the sowing amount is about one-third larger than that of spring, and the covering soil is not easy to be too thick, keeping the soil moist, which is conducive to the emergence of full seedlings.

3. Autumn sowing: generally sowing before and after the beginning of autumn, the sowing amount is twice as large as that in spring, and the management is mainly dry and wet. Attention should be paid to grass damage in the later stage. Autumn sowing is generally not recommended.

In general, leeks planted in the first year can be harvested, and they should be harvested in the morning as much as possible, and three crops can be harvested in a year when planted in greenhouses.

It is appropriate to cut 5-7 stubbles of leeks a year.

The annual harvest stubble of leeks is determined by its growth, and about 5-7 stubbles can be harvested, mainly in spring and autumn, and mainly in summer and winter. In spring, because of its vigorous growth and high quality, it is advisable to harvest a few more stubbles and keep them at 3-4 stubbles in late spring. In autumn, when the temperature drops, you can harvest 2-3 stubbles of leeks, but if you want to harvest leeks in winter, try to reduce the number of stubbles harvested in autumn.

Leeks can be harvested for ten years if they are planted once, but generally only the yield of the first two years is OK, and the yield of the latter is not good. Because the roots of leeks will also senesce, the density is too dense, and the soil lacks trace elements, the longer the yield will be, the lower the yield, so the leek planting should be replanted once every two years, and there will be no phenomenon of cutting worse and worse.

Precautions for growing leeks

1. The soil for growing leeks should be soft, fertile, well-drained, breathable, rich in organic matter and appropriate nutrients. In addition, leeks grow at a lower temperature, and slightly higher temperatures may cause them to stop growing. Therefore, it is most suitable to grow leeks in spring and autumn.

2. The most important thing for the growth of leeks is to adjust their growth points. And picking up plums and leeks will not hurt the roots because of multiple cuts. At the beginning of growth, the growing point of the leek will naturally grow upward, and after one cut, the growth point will be transferred to the root of the grass, and the second cut can be carried out.

3. Generally, use a blade to cut the grass roots, and do not use hands to pull them out directly. Also remember to water the soil at the right time after cutting to keep the soil moist. In addition, the application of the right amount of organic fertilizer can promote the growth of leeks.
