When is the right time to water wheat? When is the right time to water wheat this year

Wheat regreening water is generally watered with a stable ground temperature of about 5, and it is appropriate to water about before and after stinging, and 10 kg of urea per mu is applied in combination with watering to promote regreening. In addition, it is also necessary to adapt to the conditions of the seedlings according to the seedling conditions. Generally, wheat seedlings should be watered early, which can promote tillering in spring and improve tillering into ears.

The seedlings should be watered late, which can control the tillering in spring and prevent the population from being too large, resulting in the early wheat field canopy and lodging.

The most suitable watering time for wheat should be arranged after l0 a.m. to before 5 p.m.

The timing of watering wheat varies depending on climatic conditions and soil conditions. Generally, when the average ground temperature in the 5 cm cultivated layer soil is 5, the air temperature is 3 10, the topsoil is frozen at night and the day disappears, and the water can seep down from the soil, and the watering time is arranged as far as possible after l0 o'clock in the morning to before 5 o'clock in the afternoon.

Take advantage of the sunny and warm weather to irrigate with little water to ensure that it can seep down quickly after watering, and strictly prevent the surface water from freezing and freezing to frostbite wheat seedlings. Combined with watering, 10 kg of urea and an appropriate amount of diammonium phosphate were applied per mu to promote the rooting and tillering of wheat seedlings.

Due to the wide range of drought and the relatively tight water resources, all localities should pay attention to watering the wheat fields that are seriously affected by drought and frost, popularize water-saving irrigation technology, and irrigate 40 cubic meters per mu. After watering, when the surface moisture is suitable, it is necessary to hoe in time to protect moisture and increase temperature, and improve the utilization rate of water resources.

Wheat watering method:

1. The total number of stems per mu in the three types of wheat fields is less than 450,000, and most of them belong to late-sown weak seedlings. The management of fertilizer and water in spring should be mainly promoted. Spring topdressing should be done in two parts.

For the first time, the ground temperature of 5 cm in the regreening period stabilized at 5 o'clock to start topdressing and watering, Lunan in mid to late February, Lubei, Luzhong, Ludong in late February to early March, 5-7 kg of urea and an appropriate amount of diammonium phosphate per mu were applied to promote spring tillering and consolidate the tillering before winter to increase the number of ears per mu. The second time fertilization was applied in the middle of jointing to increase the number of grains per panicle.

2. The total number of stems per mu in the second-class wheat field is 45-600,000. The focus of spring fertilizer and water management is to consolidate the tillering before winter, appropriately promote the occurrence of spring tillering, and improve the panicle formation rate of tillering.

Hello, wheat is watered in late November to early December for overwintering. But this should be based on local climatic factors, in years with a lot of rainfall, the bottom moisture is very good, and there is no need to water it if it rains heavily after sowing. Poor bottom moisture and straw returning.

and they must be watered. The time of pouring is based on the fact that there is no water stored in the night and day. This eliminates the need for a hoe.

It is recommended to use medium nitrogen, high phosphorus and low potassium compound fertilizer for wheat base fertilizer.

Because this is determined according to the physiological needs of wheat growth, more phosphorus fertilizer is needed in the early stage, and less nitrogen and potassium are needed, so the bottom fertilizer is applied with high phosphorus fertilizer, and nitrogen fertilizer and potassium fertilizer are applied again at the jointing stage of wheat, and the effect is better.

Easy to absorb and effective.

In the process of high-yield wheat planting, water management is a very important point, especially in the last water management before winter, whether to use watering or not, when to water well, farmers often have questions.

The benefits of watering overwintering water are well understood, and for wheat planting, watering can alleviate drought, store water for spring regreening, and prevent frost damage when extreme cold weather comes. In addition to these two advantages, watering overwintering water also reduces eggs.

There will definitely be pests, and watering it this time will make it come a little less. When the weather gets colder and colder, although it is not suitable for underground pests to come out, these eggs will burrow downward, and wait until the beginning of spring next year, when the temperature gradually rises, and then come out to harm. If you water it before winter, the eggs will also be washed away, and it will be much easier to wait until next year to control the pest.

Therefore, watering winter water is particularly important for the growth of wheat. If there is a prolonged drought, then even if the leaves no longer grow, the damage to the root system is still particularly great.

When it comes to watering overwintering water, farmers often have two problems. When it was suggested to water the winter, some farmers said with disdain that watering is still expensive, and the price of wheat is not high, so it is better to save some money.

In another case, some farmers have responded to water the winter, and the yield is not high, but when the spring returns to green, there are a lot of dead seedlings, and others water to increase the yield, why do I water but reduce the yield?

There are many benefits of wheat overwintering water, and it is not recommended to follow the trend of watering, which is decided according to the soil conditions. At the same time, understand the benefits of watering, but also understand the correct way to water. Dead seedlings may be caused by late watering or excessive watering.

If you water when the cold air has come, and it freezes at night after watering, but it does not melt during the day, it will affect the growth of the root system, and there will be a situation of dead and weak seedlings. The watering time must be grasped well, not too late or too early.

Watering time mainly depends on the temperature, the temperature of each region is different, generally at 3 5 degrees Celsius when watering, in previous years, Henan this piece is about late November to early December, this year there are experts ** There will be continuous rain and snow days, to pay attention to weather changes to decide. When watering, the ground should be free of standing water, and it is best to seep it down on the same day. It's the best time to freeze at night and melt when the sun rises.

There are also herbicide plots, because the soil is dry, afraid of poor weeding effect, watered in advance with overwintering water, which can not fully play the advantages of winter water. It is recommended to apply herbicides in arid plots with an extra bucket of water to increase the absorption of weeds into the solution, and then wait until the right time to water the winter water, which is also not in conflict.

This problem has to be discussed according to the quality of the region or the land, we have a serious salinity here in the sixties and seventies, at that time it was watered twice, the first time after the frozen soil in the ground after the Chinese New Year has all melted, the ground is impermeable and easy to die. Up to now, we have watered three times here, the first time is also watered after thawing, this time the top dressing is applied at one time, first.

The second and third times are no longer top dressing, the second time is to water the spring land together before and after the Qingming Festival, laying the foundation for spring sowing, and the third time is the best time to raise the flower water, (also called grout water) At this time, wheat needs water the most! Because the wheat grains will grow to half the size after flowering, and then water them late, the wheat ears will be heavy and easy to overturn when they encounter the wind. During this period, the humidity of the wheat field must be controlled, and the humidity is easy to get "powdery mildew", and the humidity is low to affect the wheat yield.

Our farming habits here are relatively backward, the amount of planting is large, and the density of wheat is high)

The last watering of the wheat should be at the filling stage, when sufficient water is given to make the wheat grains full and increase the yield. However, if the precipitation itself is sufficient, it can also be left unwatered.

The climate and conditions are different in each place, so the watering time is different, basically watering is ten days after the wheat is about to ripen.

It should be in the wheat flowering period, as the saying goes, watering the flowers is not watering.

Wheat is yellowing and is not growing well: it is recommended to water from March 10 to March 20. The wheat is in good condition: it can be watered between March 20 and April 10.

Under normal circumstances, an acre of land uses 35 to 40 catties of urea, if you use the bottom fertilizer, an acre of land has used three 15 compound fertilizer, 100 catties, top dressing when using 20 catties of Yanxiang's urea, if you know that the growth is better, you can do it before the top stage, when the wheat enters a peak period of tillering, at this time in the top dressing can also be jujube or to.

Wheat can not be watered immediately after sowing, which can easily lead to difficult seedling emergence and poor growth, generally watering before sowing to let the soil be in a moist state. In fact, it should not be watered immediately after sowing, mainly because too much watering will make the seeds rot, and at this time, the large temperature difference between day and night watering is easy to cause soil compaction, and may also make it difficult to overwinter.

Wheat should not be watered immediately after sowing.

Many people want to water wheat after sowing it, so that wheat seeds can better take root and sprout after absorbing enough water, so that wheat can be watered immediately after sowing, in fact, it can not be watered immediately after sowing, watering before sowing to keep the soil moist, so as to avoid watering to make it grow poorly.

First of all, watering after seed sowing can not effectively control the amount of water, which may make the soil where the seeds grow too moist, which will cause the seeds to absorb too much water, resulting in rot, which will also cause wheat seeds to grow normally and germinate new sprouts.

Secondly, the climatic conditions after wheat planting make it not suitable for immediate watering, because the temperature difference between day and night at this time is relatively large, after watering it, it is easy to cause excessive water evaporation through the temperature difference between day and night, so that the phenomenon of soil compaction occurs, which will also affect the normal germination of seeds.

In addition, wheat needs to be overwintered after planting, and if it is watered too early, it will suffer from low temperature and frost damage, which will make it difficult to overwinter. Therefore, after sowing, wait until the wheat seeds grow and there are 3 or 5 leaves on the leaves, and then water them, so that they can survive the winter safely.

Wheat needs to be watered when it is planted. But how to pour? When to pour? There are pros and cons to watering the ground first or later, and the best practice is to adapt to local conditions.

What happens if you water first and then sow seeds? In fact, we generally use the latter on our side, and water it after sowing. Watering first is more suitable for plots where the soil is more prone to compaction, especially the watering method of large flood irrigation, which is more likely to cause soil compaction.

The direct consequence of soil compaction is that the emergence rate of wheat in the later stage is affected, because after the soil is compaction, a layer of hard shell will be formed on the surface, and the wheat bud is restricted, and the sprouts are easy to be broken, or it is difficult to break through the soil layer, resulting in late emergence and uneven emergence.

Therefore, for this situation, the plot is more suitable to choose the first watering and then sowing, and then sowing the wheat after the soil moisture is good, so as to avoid the situation of soil compaction after watering, and the other is that this kind of plot is best to choose the sowing after the rain, or sowing when there is no rainy day after sowing to the wheat seedling emergence period, so as to avoid soil compaction.

If the soil compaction occurs inadvertently, farmers should also take timely measures to reduce the low emergence rate of wheat, and farmers can use cocoons or harrows to help wheat seedlings unearth in time. In addition, if the soil in the planting area is very dry and sandy, and the soil moisture retention is relatively poor, this situation is also more suitable for watering first, soil moisture production, and then sowing wheat when the moisture is suitable.

For the second case, sowing first and then watering, my hometown here is more like to take, our side of the soil moisture preservation situation is relatively good, generally after harvesting corn, the large harvester directly crushed the corn stalk in the ground, and then plough the land again, if the soil moisture is good, you can sow wheat. After sowing, depending on the weather conditions, it would be best if there was a little rain in the weather, and the matter of watering would be saved. If there is no rain, the general wheat sowing should be watered about a week ago, generally choose small water, large flood irrigation is not good for the later emergence of seedlings.

And if you water first, it will be difficult for agricultural machinery to plough the land, and it will be inconvenient.

Therefore, whether it is watering first or watering later, you need to consider the local planting environment, adapt measures to local conditions, and do not blindly copy other people's practices.

Wheat fields are dry, watering first and then herbicides have a good effect.

The timing of watering wheat varies depending on climatic conditions and soil conditions.

If it is spring wheat, the soil is relatively moist, generally watering is carried out 10 days after sowing, so that it will not cause soil compaction, thereby affecting the seedling emergence rate, and the amount of watering dust should be determined according to the degree of wetness of the soil, and can not cause excessive water accumulation. If the winter wheat is sown in early October, the watering time will be longer, usually after 35 days, and the wheat can only be watered after about 3 leaves, mainly to prevent frostbite on the wheat plants and to reduce soil compaction.

If the soil is seriously cracked after wheat sowing, you can water it immediately, but you can not use the watering method of flood irrigation, otherwise it will cause the phenomenon of water accumulation, and the phenomenon of soil compaction will easily occur after the water is dried, so you only need to ensure that the soil is moist when watering.

Precautions for watering wheat:

1. Generally, the field is not very arid, so there is no need for watering, because all watering periods must be based on drought. If there is enough rainfall, there is no need for watering, which not only wastes water, but also causes the fields to become too wet and pests and diseases.

2. There is a principle of watering overwintering water, which must be carried out during the day, because the temperature will be above zero during the day, and the watering will not freeze at this time. At night, the temperature will drop below zero, and then it will start to freeze, and by the second day during the day, the ice will melt, in which case it is better to pour overwintering water.

3. The return to green water is generally started in mid to early March after the New Year, if it is not a drought in the field, you can push the Huai brother to imitate the late time, and must not be watered for the sake of watering.
