Soil cultivation is a very important management measure for cultivation, how deep is the best soil f

Among them, the treatment with the highest soil cultivation and the largest plant spacing, that is, the soil depth is 35 cm, and the green onion and onion white under the plant spacing treatment of 10 cm are the longest and centimeters; The higher the soil depth and the larger the plant spacing, the longer the green onion white. The investigation of the white thickness of green onion showed that the white thickness of green onion under the same plant spacing showed an increasing trend with the increase of soil cultivation depth, and the white onion white thickness of different plant spacing under the same soil spacing also increased with the increase of plant spacing.

Among them, the depth of soil cultivation is 35 cm, and the green onion under the plant spacing is 10 cm, although the white onion is coarse, it is cm; The depth of the soil is 25 cm, and the plant spacing is 5 cm, and the green onion white under the treatment is the shortest, which is centimeters. It can be seen that the white thickness of green onion increases with the increase of soil depth and plant spacing.

It is best to dig to a finger deep, because the seed germination rate of green onions is not very strong, if the soil is too deep, the seeds will not be able to be pushed out, and eventually the seed germination rate will be too low.

As an indispensable supplementary food material in home food, green onions should pay attention to burying all its roots when cultivating the soil, and then bury the stem a little bit to plant it completely.

<> 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 should be 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.

First of all, we should pay attention to the width of the soil, not more than 1 3 of the width, and secondly, to prevent the collapse after the rain, and the soil should also be carried out in the afternoon.

It is necessary to pay attention to the temperature control and choose the soil with a high temperature for cultivation, so that the survival rate of green onions will be high.

We must pay attention to the soil to be very nutritious, timely fertilization and watering, but also pay attention to the protection of pests and diseases, and timely spraying of pesticides.

When planting, you must learn some professional planting techniques, and you should also choose very fertile soil, and you should also keep it in sufficient light, and you also need to water it in time.

It must be pH balanced, and the soil must be fertile, and the soil must have enough nutrients so that the green onions will grow better.

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 onions, 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 the 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.

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.

The purpose of green onion soil cultivation is to prevent lodging, soften green onion white, improve the yield and quality of green onion white, the time of soil cultivation, generally in the green onion planting 30 35 days to start, about 15 days to carry out once, when cultivating soil to master a choice, that is, first loose and then tight, specifically in the beginning of the soil can not be too tight, otherwise there will be a phenomenon that the base of green onion white is too fine. Generally speaking, the height of the soil is directly proportional to the height of the green onion, that is to say, the higher the soil, the longer the green onion, and the more white and full the green tissue is.

<> should pay attention to the labor intensity when cultivating the soil, although it is time-consuming and laborious, but it is good for the yield and quality of green onionsIn the process of soil cultivation, we should pay attention to the moisture of the soil, which should not be too wet or too dry;When cultivating soil, the green onion leaves can not be damaged to prevent wound rot and infection with pests and diseases;Pay attention to the width when cultivating the soil, so as not to hurt the roots and affect the growth and elongation of the root system of green onions. After cultivating the soil, it is necessary to shoot it firmly to prevent rain from washing. Eliminate weeds, during the growth of green onions, weeds grow synchronously, compete for water and fertilizer, and also cause various pests and diseases.

By cultivating and loosening the soil, the weeds are crushed and eliminated. Fifth, improve the fertilizer efficiency of top dressing, after the application of chemical fertilizer, then cultivate the soil, cover the fertilizer in the soil, reduce the natural volatilization of fertilizer, improve fertilizer efficiency, and also help the root system of root growth to absorb nutrients.

If there are no weeds growing in the land where green onions are grown, you can imagine that there is no need to cultivate soil at all. The real reason for the soil is to get rid of weeds. The steps to accompany the soil are weeding first, and then loosening the soil.

After loosening the soil, collect and concentrate the weeds. Then pile the green onions on the sides. Then turn the soil over directly.

Pull with a hoe and cover directly with the weeds on the side of the green onion. After the covering, we just wait for the weeds to rot and slowly turn into natural fertilizer. This is also a process of green onion cultivation.

Anyone who has grown green onions knows it. Green onions need to be cultivated to trap the soil, and the real purpose of accompanying the soil is to get rid of weeds. Specifically, if you want to accompany the soil several times, it depends on the growth rate of weeds, and you can take the method of looking at the grass to cultivate the soil to solve the problem of the number of soil cultivation.

The time of soil cultivation is generally in the beginning of 30 35 days of green onion planting, about 15 days for spring and reed cover group once, when cultivating soil to grasp a choice, that is, first loose and then tight, specifically at the beginning of the soil can not be too compact, otherwise there will be a phenomenon that the base of the green onion is too fine.

Fertile soil should be selected for planting, and the soil should be loosened in time to ensure the acidity and alkalinity of the soil, and pesticides should be sprayed in time, and the soil should be cleaned regularly to keep the soil moist. Clap your fingers.

Choose soil with good soil quality for planting and soil cultivation, and pay attention to the amount of soil cultivation, and at the same time water.

Soil cultivation must choose some nutrient soil, it is best to use some planted soil, after planting green onions must be watered in time.

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.
