How many times do you need to cultivate soil during the growth of green onions? What are the precaut

It takes at least three times to better help the green onions grow. Pay attention to the process of turning the soil, but also pay attention to fertilization, pay attention to watering, but also pay attention to top dressing, but also pay attention to control the prosperity.

In the process of green onion growth, it is generally necessary to carry out about 3 times of soil cultivation.

The width of the soil should not be too wide, take the soil from the middle of the row, and the width of the soil should not exceed one-third of the row spacing, and not too deep, so as not to hurt the roots, and the soil should be pat solid to prevent the rain from collapsing.

Pay attention to the season: in the high temperature season should not be soiled, otherwise the false stem will rot because of the deep burial in the soil, the number of soil cultivation can not be too much, frequent soil cultivation will not only increase the workload, but also inevitably hurt the roots and leaves, affecting the growth of straw. Do not be too deep at a time, otherwise it will bury the leaves, which is easy to cause decay, each time the thickness of the soil is 3-4 cm, the soil will be cultivated to the boundary between the leaf sheath and the leaf body, that is, only the leaf sheath will be buried, and the leaves will not be buried.

In general, it takes three times, and you must pay attention to the growth of specific plants, pay attention to watering, and pay attention to fertilization.

Pay attention to the number of soil cultivation, the height of the soil, the fertilizer and water when cultivating the soil, and pay attention to the protection of green onion roots.

Pay attention to the number of times you build the soil

When the green onion knows that after such an autumn, it is necessary to give the green onion soil, so as to promote the growth of the green onion white when the green onion is soiled, we must pay attention to the number of times the soil is cultivated, it needs to be cultivated many times, and it should be given soil from the end of summer, the soil should be stirred evenly and then the soil should be cultivated, so that the green onion will maintain a stable upward trend, and the second picture should be carried out after entering the growth season, so that the green onion can continue to grow, and the soil should be cultivated three times after half a month, and the fine soil will be cultivated into a low stem, The last time is to cultivate a low stem into a high stem, which will make the green onion grow well and also increase its yield.

Pay attention to the height of the soil

Autumn to green onion soil to be divided into many times, each time to green onion soil to pay attention to the height of the soil, because the growth of green onion and the embryo soil has a direct relationship, if the embryo soil is too high will affect the normal growth of green onions, especially when it exceeds the growth rate of green onions, it will stop growing in its seedling stage when the soil, the height can not exceed three centimeters, when the green onion petals begin to grow, the height of the soil can not exceed 10 centimeters, when it enters the middle of growth, The height of the soil should be about 15 cm.

Pay attention to fertilizer and water when cultivating soil**

Autumn to the fruit soil is to make it grow more smoothly, at this time also to it in time to top dressing watering, to add more phosphate fertilizer and nitrogen fertilizer, can improve the quality and quality of green onions, if only with the soil without top dressing, watering will make the green onions lack of fertilizer, will affect its growth. In addition, when cultivating soil for green onions in autumn, we should also pay attention to the protection of green onion roots, and we must stay away from the root system of green onions when taking soil, otherwise water will become its roots, which will cause improper growth of green onions and reduce the yield of green onions.

The above are the places that need special attention when the green onion is mixed with soil in autumn, pay attention to these and master it later, the correct elimination method and skills, in order to give the green onion the correct soil to promote its growth as soon as possible, so that its green onion white is longer and thicker, and the yield of green onion will be significantly improved.

It should be noted that when you go to the soil in autumn, pay attention to the number and height, as well as the fertilizer and water, the temperature should not be too low, and you should often go to the soil, so that the quality of the green onions will improve.

First of all, it is necessary to do a good job of loosening the soil, and then we must pay attention to the temperature of planting when planting, and then we also need to pay attention to the humidity and density of planting, and at the same time, we also need to water and fertilize in time, and we must remove the impurities in the soil in time.

First of all, it is necessary to choose the best time for green onion cultivation, which is exaggerated to achieve "the right time, place and people". For example, when the soil is cultivated at the right time, the summer transitions to the autumn weather, the temperature gradually cools, the green onions begin to grow vigorously, the leaves continue to increase, and the leaf sheaths continue to lengthen. If the soil is cultivated in summer, the time is too early, and the high temperature in summer will easily cause green onion white rot; If the soil is cultivated in late autumn, it will be late, and the green onion plants that come out of the soil are easy to lodging.

And when cultivating the soil, the soil can not exceed the boundary between the leaf sheath and the leaf body, that is, we usually see in the cultivation of crops "only bury the leaf sheath, not bury the leaf body", if the soil is too buried in the leaf body, it will lead to the rot of green onion leaves. <>

In addition, when choosing a suitable season for the mapping, it should also be noted that the soil is loosened before soil cultivation, and then soil is cultivated. When cultivating soil, the soil on both shoulders of the green ridge should be patted to avoid collapse caused by watering or rain washing. At the same time, it should be noted that the false stems and leaves of green onions should not be harmed, because the false stems and leaves of green onions are mainly used by green onions for photosynthesis of leaves.

If it destroys the photosynthesis that may affect the green onions, the leaves of the green onions turn yellow and gradually rot. Green onions usually need to intermittently add a certain amount of fertilizer in the process of soil cultivation, it should be noted that green onions need to be fertilized during the seedling period and after maturity, and the seedling period is usually divided into three to four times of fertilization, and each fertilization time is usually determined by the length of the green onions. When fertilizing green onions during the ripening stage, nitrogen fertilizer is usually not needed, because nitrogen fertilizer during the ripening stage may cause the green onions to become white and soft, thus affecting the taste of green onions.

The reason why green onions should be cultivated is that the green onions after reasonable soil cultivation are often longer than the green onions without soil cultivation, and the lodging resistance is also better, and the taste and quality of green onions can be greatly improved, and the value of green onions can be enhanced. It can also increase the yield of green onions and the quality of green onions, so we usually carry out green onion cultivation. <>

In the process of planting green onions, it is very important to carry out reasonable soil cultivation, which can increase the length of green onion white, prevent lodging and bending, pay attention to the time of soil cultivation, reasonable top dressing, and the method and number of soil cultivation.

Green onion soil is very critical, precautions are: green onions grow to about 30 cm can be soiled, if too early soil, will lead to the growth rate of green onions is too slow, fertilizer per mu 25 kg of compound fertilizer and 150 kg of organic fertilizer, so that it can make its roots rooted, to 20 days before harvest, and then a soil thickness control of about ten centimeters, at this time the soil can make the quality of green onion white to improve, the taste will be very good.

When planting, we must choose the soil is more fertile and broad, and in the process of fertilization, we must use farmhouse fertilizer, do not use the fertilizer bought outside, but also often water, but also to prevent the occurrence of pests and diseases, if there is a situation of small insects, then we must use insecticides, which is very good for green onion soil.

The soil must bury the white part of the green onion, the soil must be fresh, it must be moist, there are no weeds in it, and there are no pests.

<> when the plant height of green onions reaches about 30 cm, it is the first suitable period for soil cultivation, if the time of soil cultivation is too early, it is easy to affect the growth of green onions, such as plant bending. From the beginning of autumn to before the harvest, it is generally necessary to cultivate the soil 3 times (the height of the soil is 3-4 cm each time), and the first 2 times can be combined with the cultivator, the ridge soil is pressed into the onion ditch, and the ditch is filled after the heat. Soil cultivation is suitable for the afternoon to reduce damage to the young leaves.

1. The best time for the first cultivation of green onions

1. When the plant height of the green onion reaches about 30 cm, it is the suitable period for the first soil cultivation, if the soil cultivation time is too early, the growth of the green onion will be affected, which is easy to lead to plant bending.

2. From the beginning of autumn to before harvesting, it is usually necessary to carry out 3 times of soil cultivation work, and the first 2 times can be carried out together with the cultivation work, and the ridge soil is pressed into the onion ditch, and it is filled after the heat. Soil cultivation is best done in the afternoon to reduce damage to young leaves.

3. The height of the green onion soil is generally 3-4 cm each time, and it can also be determined according to the growth height of the false stem, and the soil can be cultivated at the leaf outlet of the upper leaf. When cultivating soil, remember not to bury the heart leaves to avoid leaf decay.

Second, the green onion is watered a few days after the soil

1. After the green onion is cultivated, it is generally more appropriate to water once every 4-6 days, the temperature begins to drop after the frost, and the green onion has basically grown, at this time the plant's water demand for water is reduced, and the soil needs to be kept with a certain degree of moisture.

2. 5-7 days before harvesting, stop watering to reduce the water content of green onions, which is not only conducive to harvesting, but also can extend the storage period.

3. The main field management work during the late summer and early autumn is to promote roots, and the number of watering can be decided according to the weather conditions. If there is a lot of rainfall, it is necessary to do a good job of drainage and flood prevention to avoid yellow leaves, rotten roots, and dead seedlings.

4. Strengthen cultivation and promote root growth, during the beginning of autumn to white dew, it is necessary to master the principle of light watering, morning and evening watering, and the green onion will enter the peak growth period after the white dew.

The suitable time for the first time to cultivate the soil of green onions is about 30 cm in the plant height, North China generally begins to cultivate the soil for the first time after the beginning of autumn, and then cultivates the soil again every half a month, and lasts until the first half of September, when the soil is cultivated for green onions, it is usually selected to be carried out at 4-6 o'clock in the afternoon on a sunny day, and the hoe should keep a certain distance from the root system of the plant, so as not to damage the root system.

The suitable time for the first cultivation of green onion is about 30 cm in plant height, according to the growth period of the plant, North China generally begins to cultivate the soil for the first time after the beginning of autumn, and then cultivates the soil once every half a month, and lasts until the first half of September, and the whole growth period should be cultivated 3 times.

When cultivating soil for green onions, the hoe should keep a certain distance from the root system of the plant, so as not to damage the root system, and the soil is generally selected at 4-6 o'clock in the afternoon on a sunny day, when the leaves are soft and not easy to be damaged, if the soil is cultivated in the early morning, the leaves are brittle and tender, and the green onions may suffer mechanical damage.

Green onion soil cultivation is best combined with top dressing at the same time, in order to improve the commerciality and yield of green onions, fertilizer usually choose rotted soybean meal cake fertilizer, nitrogen, phosphorus and potassium content in 45% sulfur-based compound fertilizer, calcium nitrate, etc., so that the plant stem becomes thicker, enhance its lodging resistance.

When the onion occurs blight, the diseased place will appear blue-white spots, and gradually spread into gray-white spots in the later stage, you can spray the leaves or irrigate the roots with frost emulsion, in addition, the green onion is also susceptible to the harm of thrips, usually sprayed with bifenthrin for control.

Green onion soil cultivation is an important measure to increase the length of green onions, prevent lodging, and improve the quality of green onions. The following issues should be paid attention to when soiling green onions:

Timely soil cultivation: In autumn, the temperature gradually cools, green onions begin to grow vigorously, the leaves continue to increase, and the leaf sheath continues to lengthen. The soil is cultivated too early, and the temperature is too high, which is easy to cause white rot of green onions; If the soil is cultivated late, the plant is prone to lodging.

Moderate soil cultivation: When cultivating soil, the soil is cultivated to the boundary between the leaf sheath and the leaf body, that is, only the leaf sheath is buried, and the leaf body is not buried, so as not to cause leaf rot.

Reasonable soil: take soil from the middle of the row, and the width of the soil should not exceed 1 3 of the row spacing, so as not to hurt the roots.

Soil should be solid: When cultivating soil, the soil on both shoulders of the ridge should be patted to avoid collapse caused by watering or rain washing.

Avoid hurting onions: Do not hurt false stems and leaves when cultivating soil, so as not to affect the photosynthesis of leaves.

Loosen first and then cultivate: Before soil cultivation, the soil should be loosened by cultivating, and then the soil should be cultivated.

The most correct way to grow green onions is to plant them in the ground without watering them too much. Be careful not to apply too much fertilizer to large insects.

When choosing seeds, to choose a good germination rate, germination can be carried out live broadcast, as long as the same maintains enough moisture, it can improve the germination rate and seedling rate of green onion seeds, the time of delisting from the more like the cool climate, so this time is very flexible, under normal circumstances, it is sown in September, scientific fertilization, in the planting process to prepare the land and apply base fertilizer, to prevent the poison of pests and diseases, be sure to spray fungicides in advance.

The soil must be very fertile, the pH should be appropriate, the quality of the seeds should be very high-quality, more watering, more fertilization, the temperature should be appropriate, there should be a certain daily routine, it should be noted that we must pay attention to insect and pest prevention, and we must play more nutrient solutions and insecticides.
