The timing of fertilizing corn is important, is it better to fertilize in the morning or in the even

Corn has always been an important crop, and it is also very stable, and many farmers have been sowing corn for a long time. As the saying goes, "from small to large", fertilization can improve corn yields, but when fertilizer is available, catching up is not necessarily a good thing. In the process of making corn fertile, it is necessary to pay attention to scientific fertilizer in order to improve the yield.

For farmers who have been sowing corn for a long time, there are three important periods for corn fertilizer. Sufficient basal fertilizer is applied at the initial stage, seed fertilizer is sown during the sowing process, and the third is top dressing during the growth of corn. The first two chemical fertilizers are basically the same, the basic fertilizer is mainly organic fertilizer and chemical fertilizer, the fertilizer is mainly fast-acting fertilizer, and the fertilization time is also indisputable.

Everyone has their own opinions and ways of topdressing. Generally speaking, the top dressing of corn mainly uses the promotion period, male heading stage and enema stage of corn, that is, we often say stem fertilizer, granular fertilizer, ear fertilizer, and the more common top dressing also uses nitrogen fertilizers such as urea and ammonium carbonate. In order to ensure nutritional balance, some farmer friends use compound fertilizer, and in order to save fertilizer and fertilizer, some farmer friends sprinkle fertilizer directly on the foliage.

In the process of harvesting corn, some farmer friends top dressing in the morning, some farmer friends top dressing at night, and some farmer friends choose top dressing on cloudy days It is also a relatively common phenomenon, but yesterday when I browsed **, I found that some netizens raised such a question. Is corn fertilization morning or evening?

At first, I was a little confused when I saw this question, but after carefully reviewing the time of fertilizing corn, the characteristics of the fertilizer needs of corn, the fertilizer methods of various fertilizers, and everyone's opinions, I think the answer to this question should be like this. In principle, when it is time for corn topdressing, you can choose fertilizer and then topdressing. Autumn rain is best used with ditches.

That is, to bury fertilizer with soil. Otherwise, nitrogen fertilizer is easy to volatilize, resulting in a waste of fertilizer resources, when using ammonium carbonate for top dressing, if the amount of fertilizer is too large, it is easy to produce ammonia.

In the actual production process, many farmers may sometimes only have a small amount of autumn rain, and do not stick to fertilizer. Morning or evening is also available. When the soil is dry, it should be fertilized and watered.

It is best not to fertilize when it rains heavily. Otherwise, the fertilizer will be well lost in the water, and it is a good time to apply fertilizer when it encounters persistent cloudy days. For farmers who spray foliar top dressing, it is necessary to strictly control the fertilization time, complete the fertilization before 10 o'clock in the morning, fertilize after 5 o'clock in the evening, and fertilize it all day long on cloudy days, so that the fertilizer can be kept moist for a long time.

For farmers with a large sowing area, when it is time for topdressing, in fact, early spring or night should also pay attention to topdressing. Otherwise, you can delay the good chance of fertilization. For farmers with small sowing areas, it is mainly to fertilize according to their own habits and hobbies.

There is a lot of dew in the morning and a lot of mosquitoes in the evening.

The time to fertilize corn is very important, it should be better in the evening than in the morning, because if the temperature is too high during the day, it is easy to burn the roots of corn by chemical fertilizers.

The evening time is better, because on the morning of the second day, where there is sunshine, the corn is also a day to work hard to grow.

I think good morning. Because the sun is more abundant in the morning, it is easy to absorb nutrients.

Good evening, because applying fertilizer at night will not let the fertilizer burn the corn, nor will the corn be sunburned alive.

There is no difference between morning and evening, and both time periods are more humid and both are the best time to apply fertilizer. Corn is a crop that needs a lot of water and fertilizer, and theoretically speaking, there are four stages in its growth process that require the supply of fertility to meet its nutrient needs throughout the growth period. These four stages are the seedling stage, the big flare stage, the heading stage, and the filling maturity stage.

These four different periods of topdressing supply can promote the rapid growth of seedlings, promote the growth of corn stalks, promote the growth of corn ears, and promote the large and full corn grains. The topdressing of fertilizer is the most suitable stage for the topdressing of the ginseng rod period, and the favorable fertility supply can promote the growth of corn ears, and can also promote the fullness of the grains to achieve the purpose of high yield.

Fertilizing in the morning is better because there is more light in the morning, and it also facilitates absorption throughout the day and also improves yields.

Corn needs to be topdressed twice in its lifetime. The best period for the first top dressing is the big trumpet period (when the corn grows to 8-10 leaves). During this period, corn needs the largest amount of nutrients and absorbs nutrients, and the absorption rate is relatively fast.

First of all, theoretically speaking, top dressing is really important for corn growth. Because the need for fertilizer is different during each growing season of corn. Therefore, when corn is sown, compound fertilizer of about 20 kg per mu can be applied to promote seedlings and stabilize growth.

The nutrients required by maize at different growth stages are different, and the nitrogen absorbed from emergence to jointing accounts for 3% of available phosphorus and potassium. From jointing to flowering, the nitrogen absorbed is available phosphorus and available potassium is 97%.

The best period for corn topdressing is in the jointing to ear differentiation period (late June), when corn has 7-12 leaves, it is the female ear growth elongation to the female floret differentiation period, which is the key period to determine the corn ear length and ear thickness, corn can also be topdressing fertilizer is to put a little less fertilizer when sowing, to the bell mouth rain, and then chasing fertilizer is the best, in order to promote the increase of corn leaves, increase the area of photosynthesis, promote the stalk thickness, and lay a good foundation for root growth. The topdressing time of tapping rod fertilizer is generally carried out when the corn seedlings are 6-8 leaves, and the seedlings are about 30 cm high.

<> maize seedling stage, the amount of nutrients absorbed is not much, it is a slow absorption stage, and the absorption of the whole seedling stage accounts for less than 10 of the total absorption in a lifetime, but the concentration of nitrogen, phosphorus and potassium in the plant is the highest in a lifetime. Seed fertilizer can be directly absorbed by maize seeds, which has a quick-acting effect on the growth of maize at the early seedling stage, and can meet the demand for fertilizer in the early stage of maize growth. The biggest benefit of one-time fertilization is that it saves labor and time, but the yield does not increase.

During the whole growth period of corn, it is in a period of more rain, and part of the fertilizer in the soil is lost, and the situation of defertilization will occur.

The best period of corn topdressing is in the jointing to ear differentiation period (June 20-27), when the corn has 7-12 leaves, which is the female ear growth and elongation to the female floret differentiation period, which is the key period to determine the length and thickness of the corn ear.

Corn big flare stage (about 10-12 leaves of corn), is the most vigorous stage of physiological growth and vegetative growth, at this time the rhizome, leaf and ear of the plant grow and develop together, the amount of fertilizer required is the whole growth period of the most demand, the largest period, this time for top dressing, on the one hand, can provide sufficient nutrients for the growth and development of corn, on the other hand, can promote spikelet differentiation, increase the size of the ear, improve the grain saturation and single grain weight, the effect of increasing yield in the later stage is very obvious. The first time in the jointing and booting stage (accounting for two-thirds of the total topdressing), the second topdressing (accounting for one-third of the total topdressing), the first topdressing can be about 10 leaves. If time does not allow, a one-time topdressing can also be carried out in early July, but it is not necessary to do so.

Corn topdressing is generally 6-8 leaves, and the seedling height is 30 cm. Tapping straw fertilizer can promote the lushness of the upper leaves of maize, expand photosynthesis, prolong the functional period of the lower leaves, and lay a good foundation for promoting roots, strengthening stalks and increasing ears.

The best way to top dressing is to have a good topdressing effect when he has already blossomed and fruited, and the harvest rate is also very high to achieve the desired harvest.

Compound fertilizer should be pursued, because there are many nutrients in compound fertilizer, which can meet the needs of corn for all aspects of fertilizer.

The best time for top dressing is when the corn is about 50 cm high, and it is necessary to pay attention to the top dressing with phosphorus and potassium fertilizer, which will help to improve the yield.

It is best to choose at the time of jointing. It is best to pay attention to the choice of concentration, but also to send the map in advance, it is best to use well-rotted organic fertilizer, and you must not water.

The seedling stage is most suitable. Be sure to use organic fertilizer and compound fertilizer, fertilize according to the condition of the soil, and be targeted.

There is not much difference between the two, and fertilizer can be applied in the morning and evening, as long as the temperature is not relatively high.

If you want to fertilize the corn, the best thing to do is to choose the evening; The difference between the two is not big, but for evening fertilization, it will be photosynthesized and transpirated, so as to effectively improve the germination rate of corn.

Fertilization is best in the morning; The difference is not very big, but the morning fertilization can go through the photosynthesis of the sun, so that the corn can better absorb the nutrients of the fertilizer.

Catching up with 1 mu of urea 10-15 kg or superphosphate 20-35 kg, potassium chloride 10-15 kg, zinc sulfate 2 kg, etc., at this time corn is mainly vegetative growth as the main stage, divided into early-maturing varieties and early-maturing varieties, 5 early-maturing leaves, 7 medium-maturing leaves. At the same time as the vegetative reproduction and growth of the plant, there are about 11 corn leaves, and at this time the plant has grown about 60%, and the male ears have begun to differentiate. This is an important period for the formation of panicles.

At this time, the fertilizer can be mainly nitrogen fertilizer, increase nitrogen fertilizer 5 10, potassium fertilizer. If there is enough water and fertilizer, you can feed the corn ears with nutrients to increase the grains. Insufficient water and fertilizer can occur.

Male panicle quantifier, it is important that the stem stops growing after the corn is watered. Fertilization is also important at this time, as is the application of 1 10 nitrogen fertilizer. Watering to resist drought, ensure sufficient water and fertilizer in the later stage, prolong the nutrient time of leaves, help to synthesize nutrients, operate and store, and increase the yield of large spike particles.

Farmers are medicating corn, and the herbicide may be applied when the corn grows 3 to 5 pieces. Corn at this period has good tolerance and high tolerance, and the weed growth momentum is also weak, which is easy to control. Of course, in the specific process of use, it is necessary to strictly follow the instructions of the agent, and it is best to dilute it with water before application.

10 a.m. or 6 p.m., best for the effect of the medicine.

Corn topdressing is a technical job. It's not something you can catch up with at any time, and it's not something that any fertilizer can be chosen at will. The best time for corn to rain in autumn is during the trumpet, when the corn has 11-12 leaves, when the corn needs more nutrients.

I braved the light rain to go to the vegetable market to buy vegetables. In the distance, I saw a figure shaking in the vegetable garden, and when I looked closely, Uncle Xu of our village was harvesting corn in the vegetable garden. After greeting my uncle, I asked him.

Your corn grows well, why are you chasing corn in the rain now? Uncle Xu is like this. The corn is now knee-long.

There is no bottom fertilizer at the time of sowing, so at this stage without autumn fertilizer, it will be thinner. Therefore, even if it rains, it is necessary to catch up with the seedling fertilizer this time when the corn stalk is high. Otherwise, it will affect the growth and yield of corn in the middle and late stages.

It must be that there is less fertilization in the evening, when the plant does not absorb nutrients for a day, and the absorption rate will be particularly high.

In the evening, because it is easy to sunburn the corn after fertilizing in the morning and then out of the sun, it is very conducive to the growth of corn after a night of absorption in the evening and dew at night.

It is better to fertilize in the morning, because at this time the sun is more abundant, and after fertilization, the best results will be achieved.

I am a rural person, my family used to grow a lot of corn, I remember my mother seems to be fertilizing in the morning, because the morning is cooler, but in fact, it is okay, but it is best to complete the fertilization before 10 o'clock in the morning, and after 5 o'clock in the evening, so that the fertilizer can be kept moist for a long time.
