Is it better to water or not water corn spikes?

1. Water when sowing.

After sowing corn, if the soil moisture content is relatively high at the time of sowing, you can do without watering. If the soil is dry, then it is necessary to water, generally soil moisture is 65-75% of the water holding capacity in the field, which can promote the germination of corn seedlings, improve the germination rate, and prevent ridge breakage.

2. Watering during jointing.

Corn seedlings enter the jointing stage after the plant begins to grow rapidly, at this time the water demand increases, the general soil moisture is 60-65% of the field water holding capacity, if the soil water content is relatively low, it must be watered, the jointing period watering is particularly important, because it will not only affect the growth of corn plants, but also affect the heading and flower bud differentiation of corn.

3. Watering at the heading stage.

After the corn plant enters the heading period, not only the temperature will be very high at this time, but the leaf area is also the largest, so the corn in the heading period is the time when the corn needs the most water during the whole growth period, and the general soil moisture is 70-80% of the water holding capacity in the field, so the water content of the soil should be watered in time at this time. Watering at the heading stage can not only improve the photosynthesis products of leaves, but also help to improve the pollination rate of maize, and lay the foundation for early grain filling of maize in the later stage.

4. Watering during the grouting period.

After the corn enters the grain filling stage, the water requirement is still relatively large, and the general soil moisture is 70-75% of the water holding capacity in the field, and sufficient water can better make the corn grain filling, thereby improving the yield. Therefore, after the corn enters the filling stage, if the soil moisture is lacking, it should be watered as soon as possible.

Corn spit is well watered to let the fruit grow.

OK.

1. Watering after sowing.

Generally, it is watered after sowing corn, and if the soil moisture content is relatively high at the time of sowing, it can also be left without watering. When sowing, watering can promote the germination of corn seedlings, increase the germination rate, and prevent ridge formation.

2. Watering during jointing.

After the corn seedlings enter the jointing stage, the plants begin to grow rapidly, and the water requirement increases at this time, and watering at the jointing stage is particularly important, because it will not only affect the growth of corn plants, but also affect the heading and flower bud differentiation of corn. At this stage, watering* soil moisture can be kept at about 60%, if the water is too high, the root system is shallow, and the corn is easy to fall and reduce the yield in the later stage.

3. Watering during pumping.

Basically, in July and August, which is also the hottest time of the year, corn rhizomes and leaves grow rapidly, which is also the stage of transformation of the plant's energy accumulation for reproductive growth, so not only the soil moisture should be maintained, but also the fertility of the field should be sufficient. At this time, the water content in the field can be maintained at more than 70%.

4. Watering in the grouting stage.

The growth of corn plants is mainly focused on the development of ears. Sufficient moisture allows for better corn filling, which increases yields. Therefore, after the corn enters the grain filling stage, if the soil moisture is insufficient, it should be watered as soon as possible.

Watering attention: 1. Do not water at noon.

The sun is just noon, the temperature is particularly high, at this time, if the corn is watered, the contrast between cold and heat is large, resulting in the water absorption capacity of the corn root system will be reduced, in addition, after watering, the water evaporates too quickly, on the one hand, the corn does not absorb enough water, on the other hand, the soil is easy to form knots, affecting the normal growth of corn.

2. It is best to use river water for sprinkler irrigation.

According to the practical experience of the people, river water is the best water source, the biggest benefit of drip irrigation corn is water-saving and uniform, water can be released at any time, the cost is not high, some can be used every year, some are one-time, the investment is not large, and according to the farmers who have used it, this is the real cost-effectiveness, especially the benefits of dryland are better.

Water is to provide the growth of corn seedlings, lack of water is easy to cause seedlings to dehydrate and dry up and die, when the soil of the planted corn seedlings is drier, it is necessary to water in time to supplement the water in the soil, and the corn seedlings can grow normally.

Hello. Corn seedlings can be watered.

The management of maize seedlings is as follows:

1. Drought prevention, anti-compaction, and seedling unearthing.

In case of drought after corn sowing, when the soil moisture content is below 60 in the maximum water holding capacity of the field, dry seeds, dry buds and dry mold often occur, resulting in serious lack of seedlings, so it should be watered in time to loosen the soil and protect moisture. In case of rainfall, resulting in soil compaction, water should be removed in time, or hoeing loosen the soil layer, disperse moisture and breathe to help seedlings unearthed.

2. Seedling inspection, seedling replenishment and interspersal seedling.

Whole seedlings are the basis for a good yield of maize. During the emergence period, when it is found that there is a lack of seedlings and broken ridges, it is necessary to promote germination and replanting or replanting with soil in time. Seedlings are seedlings at the 3-leaf stage and seedlings at the 4-5 leaf stage.

Keep it dense and thin, and remove miscellaneous seedlings and diseased seedlings. The seedlings are right, and more seedlings can be left on the side and the ground to make up for the shortage. In the plot with heavier underground pests, in addition to timely insect control, the number of seedlings can be increased and the seedling time can be appropriately postponed.

3. Cultivating and weeding.

The seedling stage is generally cultivated 2-3 times. Before seedling setting, 1 shallow tillage (tillage depth 3-4 cm); Before jointing, combine soil cultivation and carry out 1-2 times of tillage. The depth of small tillage should be mastered by the principle that the seedlings should be shallow and the rows should be deep, and the depth of tillage is generally 6-8 cm.

Cultivation at the seedling stage is more important for interplanting maize. After the harvest of the previous crop, it is necessary to carry out cultivation and stubble removal in time, top dressing and watering to ensure full growth and strong seedlings.

4. Top dressing of seedling fertilizer.

Seedling fertilizer combined with inter-seedling application, according to the seedling conditions to apply eccentric fertilizer, in order to promote balance, generally about 1500 kg of decomposed manure per mu, or 4-5 kg of urea.

You can also use the water-soluble fertilizer of the balance of the leaves of the Vosch Plant, which is conducive to plant absorption and has a high utilization rate.

5. Control underground pests and rodents.

Corn seedlings can be watered, if it is too dry and not watered, the seedlings will dry up. But it is necessary to water when the outside temperature is low, such as four or five o'clock in the morning or after the sun goes down in the evening, otherwise the seedlings will die of heat.

Corn seedlings are not suitable for heavy watering.

It is best to use a shower for watering, and the lower the concentration of fertilizer in the water, the better, and it is appropriate to keep it at about 1:20!

Watering is required. Corn enters the maturity stage after heading, and a lot of water is needed to promote the growth of corn, and more watering is helpful for a bumper harvest of corn.

If the soil is very dry, be sure to water the corn before it is waxy. When the corn enters the maturity period, it can be decided whether to water according to the soil moisture in the field and whether the corn is in the wax maturity period, and then consider it in combination with the cost.

Yes, because at this time they also need a lot of water and nutrients to fill the corn cobs, and they also grow corn stalks at this time. Watering can make the corn stalks grow taller and get more forage.

There is no need for more watering as corn is a drought-tolerant crop. It is advisable to water corn to keep the soil quality not compacted, and the corn watering should not be too much, and the soil can be moist.

Corn watering, of course, is the best, like our hometown does not go to wine and waits for the rain to rain, the rain will grow very big, and it will be very fast.

Corn planting should be watered properly, not too much. The best time for corn watering is in the spring and summer of each year, when the plant grows more vigorously, the demand for water is greater, in the process of watering, it is necessary to directly water the water in the soil, water all the soil can be, in addition to watering, it is also necessary to provide a balanced compound fertilizer for corn to improve the growth rate of the plant.

Extension: The watering time of the corn.

1. Watering time.

The best watering time for corn is in the spring and summer of each year, when the corn sprouts and grows, joints and heads, and the demand for water is greater. In the process of watering corn, it is best to use unpolluted lake and river water to allow the plants to absorb more mineral elements.

2. Watering method.

Watering corn does not need to be too frequent, only need to be watered every other month, in the process of watering, you can water the water hose directly in the soil, but in the case of hot weather, you need to use a sprayer to spray water on the corn leaves to avoid the leaves drying out.

3. Provide nutrients.

In the process of corn growth, there is a certain demand for nutrients, and too little fertilization will lead to a decrease in the yield of the plant, so you can fertilize the corn every other month when breeding, and you can use rotten farmhouse fertilizer at the germination stage of corn, nitrogen fertilizer can be used at the jointing stage, and phosphorus and potassium fertilizer needs to be applied at the heading stage.

4. Supplemental lighting.

Corn is suitable for growing in a sunny environment, and insufficient light will lead to poor plant growth, so in daily maintenance, it can provide all-weather natural light for corn to keep the leaves green. However, when the corn is in the seedling stage, it can only provide scattered light to avoid the seedlings from blackening and dying.

When the corn reaches the late stage, it refers to the grain setting stage, which can be watered according to the moisture, and if the field is dry, it needs to be watered.

Generally, after sowing corn, it is watered, and if the soil moisture content is high at the time of sowing, it can be left without watering.

In the event of drought during sowing, watering can promote the germination of corn seeds and prevent ridge breakage.

After corn sowing, before the three-leaf stage, it is necessary to have sufficient water to ensure growth, in the past, in some areas, because of special drought, the growth of corn seedlings has a great impact, resulting in weak seedlings, or dead seedlings.

After the corn seedlings enter the jointing stage, the plant begins to grow rapidly, and the water demand increases at this time, if the soil water content is low, it must be watered, and the watering at the jointing stage will have an impact on the corn plant, as well as the heading and flower bud differentiation of the corn.

Corn is a crop with greater water demand, and the demand for water at different growth stages is different, such as less seedling stage, more jointing to heading stage, otherwise it will affect heading, pollination, and reduce yield. I don't know what stage you mean by late corn. Then I'll just briefly say it according to my understanding.

First, grouting to wax maturity stage.

After the corn enters the filling to wax maturity stage, this is an important stage to determine the yield of corn grains, at this time, although the sensitivity of corn to water is reduced, but still need sufficient water to ensure grain filling, otherwise severe drought, corn grains are deflated and not full, and the grain weight is reduced.

The experience of water management of high-yield corn is that corn should be better watered twice during this period, one is watering from flowering to grain formation, which is the key water to promote grain count. The second is milk cooked water, which is the key water to increase grain weight. In dry years, you can water the flower water, milk ripe water, and in the wet year, you can water one of them or not water according to the soil moisture.

Like this year, there was plenty of rain here, and some of the fields of corn were waterlogged. It doesn't matter what flowering milk is ripe water, now it's best not to drop a drop, and dry and dry mechanical work, otherwise it will be ruined and will have to be done manually. If it rains again, the sowing of wheat in some plots will have to be delayed, and all the waterlogging springs will occur.

Second, the wax ripening period to the full maturity period.

After the corn plant enters the wax maturity stage, the kernels have matured and entered the drying and dehydration stage, and only a small amount of water is needed to maintain the growth of the plant. Most of today's corn varieties are live stalks mature, and the water in the plant at this moment is enough to ensure the normal maturity of corn grains, and there is no need to water anymore, so as not to be greedy for green and late maturity, which will affect the sowing of wheat.

In short, after the corn reaches the wax stage, no matter how dry the ground is, you don't need to water it. The critical period for corn water demand is before grain filling, which is the critical period for corn plants to need water. Good steel should be used on the cutting edge.

You can bury the water, this period corn needs high water, it is recommended to water.

Fertilization technology at ear stage of corn:

The main field management measures at this stage are:

1. Pull out weak plants and promote roots through cultivation.

For those small and weak plants, they should be uprooted as soon as possible to improve the quality of the population. The panicle stage is generally cultivated 1-2 times. Deep tillage should be carried out at the jointing to small trumpet stage to promote root development and expand the absorption range of roots. After the small flare period, the cultivation should be shallow to protect the roots and accumulate moisture.

2. Reapply ear fertilizer.

The spring corn ear stage is an important period for top dressing. The topdressing at the panicle stage is mainly nitrogen fertilizer, and the water-soluble fertilizer of high-nitrogen functional powder can be used by soil chefs. The topdressing time is generally good at the large bell mouth period, and the specific application should be determined according to the seedling potential and soil fertility.

The fertilization method is: combined with cultivated soil, between the two plants 15-20 cm away from the corn row, dig a deep hole with a depth of 6-10 cm and a diameter of 3-4 cm, apply 25 kg of nitrogen fertilizer per mu, and apply the fertilizer to cover the soil in the hole.

3. Watering and irrigation.

Once there is a drought before and after tasseling, it is necessary to irrigate in time, otherwise it will affect the flowering and pollination of corn. During the noisy period of corn ears, the liquid key should be poured twice with water: before and after the big flare, it should be combined with top dressing for irrigation.

Before and after the second tasseling, the general irrigation amount should be large, but it should also be moderately controlled according to the weather and ground water holding capacity. Ground irrigation of corn is usually done by furrow irrigation or ditch irrigation, which does not affect the soil structure and saves water. The soil water holding capacity should be 70%-80%, if there is too much rainfall and excessive soil moisture, it should be drained in time to prevent waterlogging.

4. Prevent pests and diseases.

The main diseases and insects of summer corn ears are large spot disease, small spot disease, stem rot and corn borer, etc., which should be detected early and prevented in time.
