What is the remedy for the deep planting of wheat?

The suitable sowing depth of wheat is generally considered to be 3-5cm, and more than 5cm is defined as sowing too deep.

There are three disadvantages of sowing too deeply: first, sowing too deep, too many nutrients consumed by wheat germination, long wheat seedling emergence time, and weak seedlings after emergence. The second is to affect the uniformity of seedlings. The third is to affect the number of wheat seedlings. That is, the seedlings are uneven, incomplete, and not strong.

There are generally two reasons for wheat sowing too deep: first, the seeding machine is not matched with the land preparation method. Taking the Beijing area as an example, there are two main ways to sow seeds:

One is small seeder sowing, generally 12 rows or 14 rows, the seeder is relatively light, with about 30 tractors can be driven, suitable for a family and small plots of sowing. Because its own weight is relatively light, the quality requirements for land preparation are relatively high, and it generally has to go through 4-5 processes: corn straw crushing + heavy harrow stubble elimination + tillage + rotary tillage, <>

Moreover, it needs to be suppressed after sowing, otherwise it is difficult to ensure the quality of sowing. Another mode is large wheat planter sowing. With the increasing scale of land circulation, Beijing mainly subsidizes John Deere 1590 24-row wheat no-tillage seeder and the main 24-row wheat seeder in the 90s of the last century, with a sowing row spacing of 15cm and a width of meters.

Its own weight is very heavy, plus the weight of seeds and fertilizer, it takes a tractor with high horsepower (more than 90) to drive, so the corresponding land preparation method of this seeder is no-tillage or heavy rake and stubble after direct sowing. If rotary tillage is carried out before sowing, the sowing depth will be quite difficult to control, and it is very easy to cause the phenomenon of sowing too deep. Second, the unreasonable debugging of the seeder.

The sowing depth was not adjusted according to the plot.

There are generally three remedial measures: one is to loosen the soil before emergence, remember that small machinery should be used, and the soil can no longer be compacted; The second is to supplement water and fertilizer in time after emergence to promote the growth of wheat seedlings. The third is to take measures to continuously regulate water and fertilizer in spring to promote the growth of wheat in spring.

There is no way to remedy the deep planting of wheat, because you can't dig out all the soil, so you can only go with the flow and see if it will sprout, if it does not sprout, sprinkle it more often, but it will generally sprout, rest assured.

1.Timely replenishment and disposal in the place where the seedlings are lacking. And try to sow as much as possible, and the depth of the seed should be shallow. Let the seeds germinate as soon as possible. 2.It is also possible to manually use tools to make the soil on top of the seeds lighter.

Answer: For such wheat fields, it is necessary to do soil removal in time, and remove those excess wheat seedlings. Drag all the dirt onto the ridge and you're done. Alternatively, it is also possible to carry out seedling replenishment.

1. Weak seedlings and yellow seedlings will first cause the problem of weak seedlings, the nutrition of our land is fixed, if the sowing is too deep, then the wheat will consume too much nutrients in the process of emergence, which is easy to cause insufficient nutrients after the emergence of seedlings, causing the problem of weak seedlings.

2. The vitality of wheat seeds is not exactly the same, some may have high vitality and some low vitality, wheat sowing is too deep and the nutrients in the soil are unbalanced, it is easy to cause the problem of uneven seedlings, there may be some places where the wheat seedlings have grown tall, and the wheat in some places has not yet emerged, which will have a certain impact on the weeding work in the later stage.

3.The underground stem is too long The wheat is sown too deeply, which will cause the wheat underground stem to be too long, so that the nutrients of the wheat are wasted, and the nutrition cannot keep up with the normal growth, which has a serious impact on the yield of wheat.

4. Lack of seedlings and broken ridges When the seeds are sown too deeply, due to the influence of nutrients, oxygen, vitality and other factors, some seeds are unable to break through the soil, which causes the phenomenon of lack of seedlings, and the ridges will be broken in serious cases.

For the bucket plots that have occurred the problem of too deep seeding, we put forward the following suggestions for remediation:

1. Artificially ripping soil If our plot is not large, we can spare manpower and time to remove part of the soil above the wheat seed with tools and manually adjust the sowing depth. However, this method is more time-consuming and laborious, and it is not feasible for large plots.

2. Post-seedling remediation For farmers with relatively large plots of land, they can choose to remedy after seedlings, and the main measures are as follows. First, if there is a phenomenon of lack of seedlings and broken ridges, we must replenish the seedlings and replant them in time.

Second, if there is a phenomenon of weak seedlings and yellow seedlings, you can properly apply some urea before the year, and water properly during drought, but it is best not to flood irrigation, and pay attention to observe the growth of wheat after the year, and keep up with water and fertilizer in time.

Sowing too deep will have a serious impact on the growth and yield of wheat, so our farmers must pay attention to determine the appropriate sowing depth according to the actual situation of their plots, generally in 3 5 cm, and the ruler leakage can also be appropriately adjusted. If the problem of oversowing has occurred, measures should be taken to remedy it in time, but it is recommended that our farmers should pay attention to the problem of sowing depth when sowing.

The remedy for sowing too deep in wheat is as follows:

1. Watering and fertilizing.

If it is a plot with good wall condition, although the seedlings will emerge a few days later, if the foliar fertilizer is sprayed in time after the emergence of seedlings to supplement the nutrients consumed by the seedlings when they are unearthed, then the number of tung trees will not cause much impact. If it is a plot with a bad wall, you can water the soil once, but it should be noted that the amount of watering should not be too large, which can promote the growth of seedlings, improve the germination rate of seeds, and make them germinate smoothly.

2. Rake the soil.

In the past, many farmers would use this method to use bamboo rakes or other tools to spread soil on the surface of the sown field, so as to artificially reduce the sowing depth, but this method consumes a large amount of labor and is not suitable for large-scale planting.

3. Replanting in time.

After the wheat emerges, when it is found that there is a lack of seedlings and broken ridges, it is necessary to replant in time, and sow as shallow as possible when replanting, so that the wheat seedlings can emerge as soon as possible and the seedlings are full. Tuanlun base.

Wheat sowing too deep harm:

1. Wheat seedlings will be affected, if the seed vitality is not strong, because the seed is too high from the surface, it cannot break through the soil, resulting in the phenomenon of lack of seedlings and broken ridges.

2. The seedling is weak, because the sowing is too deep, and the wheat will consume too much nutrients when the seedlings emerge, so that when the seedlings grow, the seedlings will be weak and the seedlings will be yellow.

3. The tillering is reduced, and the plots that are sown too deeply, because the seedling emergence time is normal and the wheat is late, so the tillering will be reduced in the later stage.

Avoid crushing: Use harvesting methods that do not easily cause crushing or damage to the ears of rice to minimize damage to the germinated wheat. Hand harvesting:

Choose manual harvesting to avoid poking back and cutting off small seedlings during the pre-harvesting process of machine harvesting. According to the quality classification: the germinated and non-germinated wheat are separated and processed in different ways, and the germinated wheat can be used as feed.

Now while the wheat seedlings are still relatively weak and cautious, before and after the leaf period, take advantage of the moisture with an iron rake horizontally or harrow a few times, you can also manually pull out or hoe some wheat seedlings, take such a method, you can damage some wheat seedlings, play the role of seedlings, should be able to reduce the number of basic seedlings per mu. In the wheat division period and before the early spring jointing, the wheat field is relatively dry and rolled once or twice, which can play the role of squatting seedlings and controlling the growth of the seedlings. It can also be used to make the sheep eat and trample more quickly before the wheat stool gets up.

At the same time, a small amount of compound fertilizer can be applied.

Pay attention to prevent the phenomenon of weak seedlings caused by defertilization.

This not only promotes vigorous growth of wheat puree, but also controls water and fertilizer. Dense wheat shearing is caused by too much basic seedling wide coarse hail. Although inhibition can also control the rapid growth of the population to a certain extent, the control effect is relatively poor.

Wheat can usually be inhibited before and during the transition over. Field soil moisture is a reduction in ineffective wheat tillering.

The main factors. At the same time, a prosperity control agent can be sprayed to reduce overgrowth and wheat density.

The management of water and fertilizers should be properly controlled. Chemical control agent in crushing, potassium monophosphate.

leaves of fertilizer, strengthening talc.

If the wheat is growing too fast, drugs can be used to control overseeded and overdense wheat fields. So how should we do corrective management? There is no harvest of crops and no harvest of land!

Good penetration is certainly a good thing. But for over-dense wheat fields, do farmers need the right management experience? There are two ways to do this:

Control slimming and sowing, these two methods are: in the initial stage, the wheat is sown deeply, the wheat is sown without fruit, and the sowing appearance is poor.

Wheat is sown deeply, wheat is sown not fruit, and growth is poor! Timely clearing of soil and trees, starting with an iron rod from the center of the border of the ridge. When clearing to the last row, drag all the remaining soil behind the border, i.e. sowing in the middle.

On the earth with high planting density, there is no need to process too many wheat seeds. When seeds are sown, they cannot be recovered. If wheat seeds were found to be very dense and flourishing many years ago, they can be rolled or milled.

In this case, the parameters of the wheat planter must be adjusted, the rough burial must be ended, the soil is picked up, and then the trees must be cleared, and then the water and fertilizer management must be strengthened.

If they sow too much, they can adjust the sowing depth of the planter, so that the sowing depth can reach a range that they can accept.

I think the best way is to artificially reduce the thickness of the soil layer so that the wheat can emerge normally.
