The detailed process of the growth of leeks, the growth habits of leeks

Sow seeds, sprout, sprout, grow.

The growth habits of leeks are:

Leeks belong to the lily family perennial root vegetables, which are adaptable, cold and heat resistant, and are cultivated everywhere in China. In many areas in the south, it can be produced all year round, although the aboveground part of the north dies in winter, the underground part goes into dormancy, and the topsoil thaws in spring and germinates and grows.

Leeks like cold and cool, cold and heat tolerant, the seed germination temperature is more than 12, the growth temperature is 15 to 25, and the underground can tolerate lower temperatures.

Medium light intensity, strong resistance to negatives. However, if the light is too weak, the accumulation of photosynthetic products is less, the tillers are less and weak, the yield is low, and it is easy to premature aging. The light is too strong, the temperature is too high, there are many fibers, and the quality is poor.

Harvesting of leeks:

The number of leeks harvested each year depends on the growth of leeks, fertilization and market**. In winter and spring, the arch shed leeks can be harvested 3 stubbles. Although the autumn quality is good, in order to cultivate roots and lay a material foundation for the growth of arch sheds, it is advisable to harvest L-2 stubble.

Leeks are cut with 7 leaves and 1 heart. Early morning harvest is best. It is advisable to cut 3-4cm yellow leaf sheath on the bulb.

In the future, each knife should be slightly higher than the previous stubble to ensure normal growth. The yield is low in the first 1-2 years after planting, 3-6 years is the peak growth period, the yield is the highest, and it enters the senescence stage after 10 years, so it should be transplanted in time.

The growth cycle of this vegetable is as follows:1. Germination period: From seed germination to the first true leaf of the young bud, this stage is the germination period, and the whole excavation process takes about 10 days.

However, the time required for different varieties is not exactly the same, and some varieties germinate very slowly, and the emergence period is about 12-15 days, or even longer.

2. Seedling stage: from having the first true leaf to having the ability to divide the plant is the seedling stage. It takes 70-80 days for general varieties and 60 days for fast growth.

The growth of the aboveground part is relatively slower in this growth stage, and the root growth is the main thing. The value can be determined when the seedlings grow to 18-20 cm.

3. Vigorous growth period: from the beginning of the ability to divide the plant is the vigorous growth period, and the division begins to occur. The specific number of branches also depends on the variety. Among them, the narrow-leaved varieties are rented four or five times, and the broad-leaved varieties are rented two or three times a year. During this period, it is necessary to pay attention to the management of light and temperature of round slag.

The growth cycle of leeks is three to four months, and the growth process of leeks is divided into three periods. During the first germination period, from the germination of the seeds to the growth of the first true leaves of the young buds, the whole excavation process takes about ten days. The second seedling stage, from having the first true leaf to having the ability to divide the plant, is the seedling stage, which generally takes 70 days.

The third vigorous growth period is the vigorous growth period from the beginning of the ability to divide the plants, and some narrow-leaved varieties are divided into four or five times, and the broad-leaved varieties are divided into two or three times a year.

The growth cycle of leeks is three to four months, it is planted once, it can be continuously fertilized and managed, and the fertilizer generally applied is plant ash, so that leeks can be harvested continuously, and in the process of planting, ventilation and light transmission can be maintained, which can make leeks grow continuously for about 3-5 years.

The growth process of leeks.

1. Germination period

The growth of leeks only goes through three processes, the first germination period, fromThe seed germinates to the young shoot, and the first true leaf growsThe whole excavation process takes about 10 days

2. Seedling stage

The second seedling stage, from thereThe first true leaf to have the ability to divide is the seedling stageIt usually takes seventy daysIt takes sixty days to grow fast

3. Vigorous period

The third period of vigorous growth, fromThe beginning of the ability to divide the plant is the period of vigorous growth, the specific number of branches also depends on the variety, and there are someThe narrow-leaved fretridge basal species are divided into four or five timesBroad-leaved varieties two or three times a year

Leek cultivation. 1. Land preparation

Plough the land, plough the depth of 20-25cm, and rake in time after ploughing, so that the land is flat, no stubble, no stubble. The general area is 4-5m wide and 10-15cm high, the purpose is to facilitate watering.

2. Watering

Water a week before sowing, and this time be sure to water thoroughly. After watering, ensure that the water in the small furrow is 3-5cm deep, so that it can infiltrate naturally.

3. Pre-sowing germination

4-5 days before sowing, germination, in 30 warm water, soaking for about 24 hours, into the water soaking process, to remove the seeds and impurities floating on it.

After soaking, wash with cold water, then wrap 2-3 layers with clean gauze and place it at 15-20 times to induce germination. Special attention should be paid to washing with water 1-2 times a day during germination, and 3-5 days refers to ignition of buds.

4. Sowing

The row spacing is 10cm, the ditch is 2cm deep, the seeds are sown in the ditch, the soil is covered about 1cm, and there are wooden boards patted after the soil is covered, so that the seeds and the soil are fully contacted. Cover with plastic film to protect moisture, generally about 5-7 days can emerge.

5. Promote strong squatting seedlings

When the leek is about 10cm high, the water can be controlled, and it can also be covered with fine sand and soil after stirring evenly, the thickness of the soil is 3-5cm, and it is covered again when it is 10-15cm, and it is generally covered 2-3 times. In addition, when planting in early spring, you should pay attention to keeping warm at night, if the temperature is low, you can cover the film to keep it warm, and keep it at L8-20 at night.

6. Harvesting

After squatting, the 4 leaves are harvested for the first time, and the stubble is left 2-3cm during harvesting, and the dead leaves and weeds in the field are removed after cutting. After the wound has healed, the seedlings are cultivated when they reach 10-15 cm, and the second harvest is made when the plants have grown to 5 leaves.

How long is the growing period of chives.

The growth cycle of leeks is about 90 days, but this time is not fixed. The growth cycle of different varieties of leeks is also different, which is also related to the local climate and later maintenance. The growth of shallots will go through many stages, such as the germination stage, the seedling stage, and the shallot formation stage.

Most of the plants are planted around Qingming and Guyu and take half a year to mature.

The growth process of chives.

1.Germination period: It is its germination period from sowing to the growth of the first true leaf, which lasts about 10-15 days.

2.Seedling oak search period: The seedling stage of green onion is from the appearance of the first true leaf to the planting of the plant, during which the plant grows slowly.

3.Onion white formation period: About 10 days after planting, green onion white will enter the green onion white formation period.

At this time, the false stem of the plant will grow rapidly and become thicker.

Maintenance and management of chives during the growth period.

1.In the seedling stage of shallots, it is necessary to apply seedling fertilizer once, and at the same time, through seedling weeding, it can promote the healthy growth of seedlings. 2.Frequent fertilization should be applied during the formation period of green onion white, which will help the plant accumulate nutrients and improve the quality and yield of green onion white.

Introduction to the growth of leeks.

Leeks are suitable for growing in fertile soil. It requires prepared human and animal manure and more nitrogen fertilizer. Shandong is the main production area of leeks, including Linyi, Dezhou, Longkou, Yantai, Xinxian, Liaocheng, Zhangqiu, Jinan, Pingdu, Qingdao, etc.

Leek growth cycle.

Leeks are perennial vegetables of the lily family. Because of its adaptability, strong Qinavol, cold and heat resistance, short growth period, three to four months, it is cultivated all over China. Many parts of the South can produce all year round.

In the north, although the aboveground parts die in winter and the underground parts go dormant, the topsoil sprouts and grows again after the spring thaws. Leeks are cool, cold-tolerant and heat-resistant, with moderate light intensity and strong shade resistance. The suitable air relative humidity is 60-70% and the soil moisture is 80-90% of the maximum field water holding capacity.

It has strong adaptability to soil texture, is suitable, requires a large amount of fertilizer, and has strong fertilizer tolerance.

Leek growth rate.

1.Germination period: The germination period is the time from the beginning of seed germination to the time when the bud extends and grows the first true leaf.

The whole germination process generally takes about 10 days. Some seeds with tight grain size or deep sowing can last up to 12-15 days, and some even longer. 2.

Seedling stage: The seedling stage starts from the first true leaf and ends when there is the ability to divide the plant. During this period, 8-10 leaves and 10-15 roots will grow.

It takes 70-80 days for general varieties and 60 days for fast-growing varieties. 3.Vegetative growth period:

When the stem disc has the ability to branch from the growth point, it enters the vegetative growth period and begins to branch.

Leek growth cycle management.

The yield per mu will vary slightly depending on the variety of leeks planted. Under normal cultivation management, the yield of leeks per mu is about 3,500 catties.

Temperature management. The surface temperature of leek planting must be stable at more than 12 degrees, the average daily temperature must not be lower than 15 degrees, and the underground part can withstand lower temperatures.

Fertilization management. When plowing, apply sufficient basal fertilizer. The topdressing time of leeks should be determined according to the growth rate and weather conditions.

When the plant height is less than 30 cm, spray 400 kg of 3% compound fertilizer water per mu. When the height is more than 30 cm, apply 1000-1500 kg of organic fertilizer and 10-20 kg of compound fertilizer per mu. When the weather continues to be dry, it is necessary to add more water to the fertilizer before applying it.
