When is it good to water wheat? Can wheat be watered now?

What is the best time to water wheat? Why? As long as the soil moisture in the wheat field is insufficient, it is most appropriate to water it in time, because when the moisture is insufficient, it will affect the normal growth of wheat and reduce the yield, especially in the high-yield cultivation of wheat in several key growth periods.

After sowing wheat, it can rain or snow before the temperature of sub-zero in winter arrives. At this time, farmers generally do not water overwintering water. If the weather is dry and there is no rain or snow, you should start watering at noon in mid to late November of the solar calendar, when the daytime temperature is 8 10, and if the temperature is too low, you can't water.

Covering the head water, generally for the sowing of moisture, when the moisture in the field is insufficient, it can be carried out after the wheat is sown. There are also wheat watering when the field moisture is better when the sowing is good, which is conducive to sowing the whole seedling and laying the foundation for the high yield of strong seedlings. After the head is watered, the topsoil should be hoeed in time to prevent the topsoil compaction from affecting the emergence of seedlings.

Overwintering water, generally in the winter cold, rain and snow juvenile parts should be carried out in time before wheat overwintering, not only conducive to the field to bridge the soil, but also to the safe wintering of wheat to prevent frost damage. Generally, the wintering water is carried out at an average daily temperature of about 3-4, and the night freezes and the day disappears. If there is a lot of rain and snow, you can not do it.

Back to green water. It is particularly important for the high yield of wheat in the area of insufficient rainfall in spring, which can generally be carried out when the average daily temperature continues to be stable above 3, and the production is mostly combined with green fertilizer for watering, so as to promote the rapid growth of wheat and facilitate the formation of ears.

Jointing booting water. For the fields that have not been watered back to green water, it is necessary to water and apply jointing fertilizer at the jointing stage of wheat to meet the fertilizer and water demand for rapid growth of wheat.

Wheat grain filling water, for the later rainfall is insufficient area, generally wheat heading and raising flowers should be watered with grain water, which not only promotes grain filling and increases yield, but also can prevent dry and hot wind damage, prevent premature aging, increase grain weight and increase yield. If the ear fertilizer is insufficient, the grain fertilizer is also applied.

In short, wheat should focus on watering back to green water, pulling water or booting water and filling water, etc., and the specific watering times should be flexibly used according to local meteorological conditions and soil moisture content in the field.

1. Winter irrigation. Water once a year in mid to late November. Helps reduce underground pests and germs. It is conducive to the safe wintering of wheat.

2. Return to green water. The year after wheat planting, in early spring 23 months, when the soil thaws and warms up, it can be watered once. By the way, urea is sprinkled to supplement nitrogen fertilizer for wheat, which is conducive to the rapid rejuvenation of wheat and the role of strengthening seedlings.

3. Grout water. After the wheat is pollinated in May each year, it goes to the grain filling period. At this time, watering water will increase wheat production and income.

For winter wheat, from sowing to harvesting, in general, there are 4 watering periods, namely hooded water, overwintering water, regreening water, and grout water, however, it is not for everyone to water these 4 periods (the cost is too great, and too much watering is not conducive to the growth of wheat), but according to the specific conditions of the field, choose one or two periods for watering.

Generally is about 7-10 days after sowing, some places are more dry when planting wheat, resulting in poor wheat seedlings or weak seedlings due to drought after emergence, at this time watering once, conducive to the growth of wheat at the seedling stage, whether it is the seedling rate or the seedlings are strong, have a certain effect.

Hello, I'm glad to answer for you, now wheat can be poured with some farm fertilizer water, anti-freezing. According to the soil moisture, if the soil is dry, it can be irrigated in time to prevent wheat frost damage. Wheat should not be watered after entering the overwintering period.

Wheat is a bit dry at the moment and can be watered. Wishing you a happy <>

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.

Spring wheat is watered in early March.

At this time, the wheat has entered the regreening period, and the temperature must be stable above 5, and watering at noon. Watering too early is easy to reduce the ground temperature, and the call section affects the wheat to green. In sandy soil with poor water retention capacity, the amount of watering should not be too large.

After watering, spring wheat is easy to grow, and it is best to suppress it after the water seeps down, which can not only alleviate the drought, but also help control the prosperity and become stronger.

Wheat spring water should be watered as late as possible, and pesticides should be applied first to prevent diseases and insects. The cohesive soil with strong water retention capacity is higher than 70 in the field, and it can be dispersed when it is loosened, which is suitable for wheat growth. If you water again, the soil moisture will be high, and the root permeability will be poor, which will increase the occurrence of diseases.

Growth habits of wheat:

The soil layer is deep, the structure is good, and the tillage layer is deep, which is conducive to water storage and fertilizer conservation, and promotes root development. Soil structure refers to the composition ratio of solid (organic and inorganic), liquid and gas, which is closely related to soil moisture, air, temperature and nutrients.

The average daily temperature of winter varieties was 16 18, semi-winter was 14 16, and spring was 12 14. The temperature of the sky is affected by the geographical latitude and altitude, that is, the higher the latitude and altitude, the lower the temperature, and the earlier the sowing date.

Wheat long day crops (8 to 12 hours of light per day) if the sun conditions are insufficient. It will not pass through the light stage, and it will not be able to tassel and bear fruit. The light stage of wheat is after the vernalization stage.

Do you still need to water after the wheat flowering period, when do you need to water it, and when do you need to water it, and when you don't.

Hello answer, please wait a while, in the inquiry information, in the preparation for your answer, thank you....Hello, watering needs to be based on the growth habit of wheat, under normal circumstances, wheat needs to be watered 3 4 times in a lifetime, that is, after sowing the head water, winter frost overwintering water, after the Spring Festival back to green water, April and May grouting water, that is, our people say wheat water, but wheat watering is not the more the better, but according to their own soil moisture, some places if the soil moisture is not bad, perhaps as long as the water is watered wheat can be harvested, but in some places because of the severe drought, Then you need to water four or five times, but in most cases it is usually three times.

Wheat can be watered. Wheat watering is particular: the time and frequency of spring watering are not only related to the yield of wheat, but also related to the quality of wheat.

The effects of watering on wheat yield and quality were also related to different precipitation years, soil fertility and fertilization levels. In general, watering increases grain yield and protein yield, but protein.

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.
