If the wheat is not planted, it is better to water it before it is planted, but it is better to rain

Wait! What if it doesn't rain? That doesn't affect next year's earnings! Plant a shadow first and earn next year! Planting is steady.

There is a proverb that says that "wheat is planted, autumn is in management", as long as the wheat is sown, the moisture is sufficient, the field is cultivated as the bottom of the real and the virtual, and then the foot fertilizer is applied, the next year is a bumper harvest year, so the wheat must be intensively cultivated when planting.

Then, it is the primary condition for planting wheat to understand the soil moisture and planting time, and the suitable soil relative humidity for wheat emergence is 70% to 80%. The agricultural proverb says: "Late sowing is weak, early sowing is prosperous, not too late, not early wheat seedlings strong." ”

If the soil moisture can generally be sown dry, but the rainfall is large after sowing, then it will be troublesome, easy to cause the ground to be compacted after the impact of raindrops, and after the sun is irradiated after the sunny day, a layer of hard scab is formed on the surface of the ground, causing the wheat seedlings to sprout. If there is a light rain for a few days after the wheat is sown, the moisture required for wheat emergence is guaranteed, which is conducive to the improvement of the emergence rate.

Sowing wheat after the rain believes that the advantages outweigh the disadvantages, one is to use the moisture after the rain to cultivate the field and ensure that the land is level. It is especially important for the land where the wheat is planted, which can be deeply turned to achieve good planting results. Second, good moisture is conducive to the one-time sowing of wheat seedlings, and the sowing amount can also be appropriately controlled to prevent the phenomenon of vigorous growth after the sowing of wheat is large.

Third, global warming, wheat sowing can be delayed by about ten days, such as the rainy period delayed by about ten days, is a good time for sowing.

In short, sowing before rain may cause poor seedling emergence rate, after the surface soil is easy to form compaction, some wheat seedlings have been unearthed, and some seeds are blocked by the compacted layer, forming a row of wheat seedlings green, a line of no wheat seedlings. In our general formation of this compaction situation, it is necessary to use a rake to hug the ground, destroy the soil compaction layer, which is conducive to the wheat seedlings soil, but after this treatment, the wheat seedlings can not reach the whole seedling neatness, and affect the yield.

It is a cause for concern that the soil will be moistened and the surface will be compacted due to the rain that has just been planted, which will cause the seeds to be stuffy and not germinate. Of course, there are some farmers who think that this is a timely rain, and the soil moisture is insufficient before sowing, which just saves watering and can improve the moisture, which is conducive to the seedlings and seedlings. There are also plots that have been sown early and have already emerged, and after the rains, the wheat grows faster.

So, back to our worries, will the rain just after the wheat is sown affect the emergence of seedlings?

I think the benefits of this rain are still favorable, and there is no need to worry too much, which is similar to the reason for pouring water on the head after sowing. As long as the wheat meets the conditions of temperature and humidity after sowing, then it will not affect the emergence of seedlings.

In terms of temperature, an autumn rain and a cold, the temperature has also dropped in the past two days, and if it is lower than 15 for a long time, it will affect the emergence of seedlings. Note that the low temperature for several days in a row may delay the time of emergence, if there is a day or two that does not have much effect.

In addition, many farmers will sow seeds first and then water them in order to catch up with the planting date. Soil moisture also increases after rain, which is more suitable for seedling emergence than when the soil is dry, and also saves the need for watering. Generally, clay soil is watered first and then sown, if the wheat is watered before the emergence of seedlings, there will be soil compaction, high humidity and other problems.

For now. The rain is always light rain, unless there will be water accumulation in some low-lying places, and in more arid places, after the rain in time, there is still drought in the deep soil layer.

Therefore, I think that farmers should not worry too much about the plots where the wheat is sown and it rains as soon as the wheat is sown, or the plots where the seedlings are not yet available. My idea is to wait for the seedlings to look at the growth of the seedlings, when there are weak seedlings, you can spray a fertile leaf amino acid foliar fertilizer to promote the growth of seedlings, and if there is a lack of seedlings, you should also replant or replenish the seedlings.

It rained as soon as my wheat was planted, so it's okay. I think that's a good thing. Your wheat has just been planted and it rains. As soon as the wheat is planted, it should be watered with water. In this way, the wheat can grow a little faster.

It should be fine, a long time ago, people planted wheat with that kind of woody wheat planting equipment, before the light rain will not come out, and now the new wheat planting machine is equipped with a compacted device, and a little rain will not affect the emergence rate.

The problem is not big, if the newly planted wheat is most afraid of heavy water irrigation, even cloudy days, if this is the case, the wheat seed will cause rot, reduce the germination law, and cause a reduction in yield.

From the experience of old farmers;

If the newly planted wheat is most afraid of heavy water irrigation and cloudy days, this situation will cause rot of the wheat seeds, reduce the germination law, and cause a decrease in yield.

If it rains and there is no water in the ridges, there is no need to worry.

There is no obstacle to wheat seeds.

The situation of whether it is better to water the wheat now, or not to water it is as follows:

1. Watering before sowing. According to different planting habits, some people choose to water 3-5 days before sowing, and after watering, after the field can operate normally, plow, rotate and other operations.

There are also people who choose to water the last crop a few days before harvesting, such as the corn planted on the stubble, about 5 days before the corn harvest to water, after the corn is harvested, and then sow wheat, so you don't have to worry about moisture.

Take the way of watering first and then sowing, a very important advantage, the soil in the field will not appear compacted, after watering, affected by the high temperature at noon, the soil may be compacted, at this time, ploughing, rotary and other sowing work, the soil will become finely broken, which is conducive to the germination of wheat, seedling work.

2. Watering after sowing. After the wheat is planted, some farmers water it immediately, while others water it a few days later.

If there is no rainfall for a long time before wheat sowing, rotary tillage is about 15cm, and the soil is still relatively dry, in this case, after wheat sowing, wheat seeds can not absorb sufficient water, affecting the emergence rate. At this point, watering can be carried out immediately after sowing.

How many days after sowing winter wheat is good for watering:

Winter wheat sowing 10 15 days after watering better, at this time the plant has adapted to the new growth environment, can carry out normal growth and development, at this time watering to water thoroughly, will not cause the phenomenon of soil slabbing, to ensure the normal growth of the plant roots, before the plant wintering on the line of watering, keep the soil in a semi-dry and semi-wet state.

Now watering wheat has an impact on wheat, and wheat watering needs to be treated according to the situation: head covering water, overwintering water, rejuvenation water, and grout water.

1. Cover your head with water

The time of watering the head water is generally about 10 days of wheat sowing, which is suitable for the relatively dry situation in the field, improving the emergence rate of wheat, and ensuring the normal growth of wheat at the seedling stage.

2. Overwintering water

The time of overwintering water, under normal circumstances, is carried out around mid-November (also depends on the specific local situation), and the purpose of this watering is mainly to prevent frost damage and ensure that the wheat can safely overwinter. According to the planting experience, after watering, it will not freeze during the day, and it can freeze at night, and it can thaw during the day of the next day, which is more suitable at this temperature.

3. Return to green water

The water is watered when the wheat is green, usually around March of the following year. Wheat after a winter "baptism", wait until spring, the temperature rises, everything recovers, wheat begins to grow rapidly period, watering a return to green water, is conducive to the growth needs of the middle and late stages.

4. Grouting water

Grain filling water is watered once during the wheat filling period, the time is about May, and the watering is once during this period, which is conducive to wheat filling, full grains, and plays a role in increasing income and quality.

Growing Environment:

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.

Summary. Wheat is a food crop planted in the spring and generally matures in autumn, so it is already the season for wheat harvesting and is not suitable for watering. If the wheat is short of water during the growing period, it can be watered in moderation, but the following points need to be noted:

Control the amount of watering: Wheat needs adequate water during the growing period, but excessive watering can lead to insufficient oxygen in the soil, affecting the growth of wheat. Therefore, it is necessary to control the amount of watering and avoid overwatering.

Control the watering time: Wheat grows most vigorously in the evening and morning, and watering during this time can effectively replenish soil moisture. If watered during the day, it may cause the water to evaporate too quickly, affecting the growth of the wheat.

Pay attention to drainage: After watering, you need to pay attention to drainage to avoid water retention in the soil and affect the growth of wheat. In short, watering can help wheat growth to a certain extent, but it is necessary to pay attention to controlling the amount and time of watering to avoid affecting the growth and yield of wheat.

Just these few days, is it okay to water.

After watering, it is necessary to pay attention to drainage to avoid water retention in the soil, which will affect the growth or growth of wheat. In short, watering can help wheat growth to a certain extent, but it is necessary to pay attention to controlling the amount and time of watering to avoid affecting the growth and yield of wheat.

Can watering prevent the cold in spring?

Inverted spring cold refers to a natural phenomenon in which the temperature drops sharply in spring, which may lead to frost damage to crops, and watering cannot completely prevent inverted spring cold. However, moderate watering can increase soil heat retention and slow down the rate of decline in soil temperature, thereby producing a protective effect on crops, or reducing the risk of frost damage. Therefore, proper watering can alleviate the impact of the cold to a certain extent.

In addition, if you are planting some crops with strong cold resistance, such as wheat, barley, rape, etc., you can appropriately increase organic fertilizers and phosphorus and potassium fertilizers during the planting process to improve the cold resistance of the plants. At the same time, covering material can also be used to keep warm to avoid the impact of the crop from the cold of the spring.

1. If it is planted with spring wheat, the soil is relatively moist, and it is generally watered 10 days after sowing, so that it will not cause the phenomenon of soil compaction, which will affect the seedling emergence rate.

2. If it is winter wheat sown in early October.

Watering will take longer, usually after 35 days (late November), until the wheat has grown about 3 leaves, mainly to prevent frostbite on the wheat plants and to reduce soil compaction.

3. Generally before wheat sowing, a large area of watering will be carried out to ensure that the soil is in a moist state, and the seeds of wheat will quickly take root and germinate at the end of the dormant period after sowing, watering will affect the growth of wheat, and then watering can be carried out once after winter, so that the roots have grown thick and strong, and can absorb sufficient water.

4. 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 evaporated, so you only need to ensure that the soil is moist when watering.

After the wheat is planted, it should be watered, and there is actually water after wheat sowing, and there are Pingli wheat seeds to absorb water and germinate.

If you plant spring small or wheat, and the soil is relatively moist, it is generally watered about 10 days after sowing; The winter wheat sown in early October will be watered for a longer time, generally after 35 days (late November), and wait until the wheat has about 3 leaves for watering, mainly to avoid frostbite to the wheat plant, and to reduce soil compaction.

According to the moisture of the soil, it is generally not more than 7 days to destroy the state. Because the wheat that has just been planted must not be covered by the soil, so that it is impossible to germinate, which causes the wheat to be uneven after the long traces come out, so it is best not to water it once every 7 days, so as to avoid the unevenness caused by the long germination interval of wheat. ”
