Can corn cobs die if they are flooded for two days?

*Corn cobs that are flooded for two days do not necessarily die**, but it depends on the severity of the flooding.

If it's just a slight flood, and there's no lodging breakage or anything like that, and there's no smell of alcohol, then the corn won't be too badly affected. However, if the smell of alcohol appears in the flooded crops, it means that the crops have begun to breathe anaerobically, and the starch stored inside has begun to ferment and decompose, in which case the corn may die.

In general, if the corn is flooded for a longer period of time or if the flooding is severe, it may adversely affect the growth and yield of the corn and even lead to the death of the corn. When this happens, it should be drained as soon as possible to allow oxygen from the soil to enter to help the corn resume growth.

Depending on the severity of the flooding, if there is a break or silt covering the corn stalks, then the yield of the corn will be seriously affected, if it is only flooded without lodging and breaking and there is no smell of alcohol, then the corn will not be affected too seriously, generally if the flooded crops have an alcohol smell, the basic crops will be drowned or about to be drowned, because the smell of alcohol in the crops indicates that anaerobic respiration has begun, and the starch stored inside the crops begins to ferment and decompose, and the crops are drownedIf there is no smell of alcohol, the crops can be saved, and as long as the flood waters recede, they will survive again!

Live, corn needs a lot of water but is not waterlogged, here are a few emergency remedies for you!

1. Drainage and stain reduction. The flooded corn field should be ditched and desilted in time, and the plants should be straightened. After the rain, the lodging plants should be lifted in time, and the soil should be cultivated as far as possible without damaging the aerial roots, and attention should be paid to removing the foliar sediment and raising the feet.

3. Cultivating loose soil. When the ground is white after precipitation, it is necessary to cultivate and loosen the soil in time, break the soil compaction, promote the soil moisture and breathability, improve the rhizosphere environment, and promote the growth of the root system. Lodging corn seedlings should be straightened in time and the roots should be cultivated.

Fourth, weeding and top dressing. For the fields drained and waterlogged, choose to increase nitrogen fertilizer on sunny days, and apply water-soluble fertilizers with high nitrogen macroelements in Haihai and Weihai to promote the normal growth of corn. For a large number of rainy and sunshine days, increasing nitrogen fertilizer can improve greenness, promote photosynthesis, and alleviate nitrogen hunger after waterlogging.

Appropriate amount of phosphorus, potassium and micro-fertilizer. Promote the recovery of corn growth and reduce yield loss.

Fifth, plough and replant. For fields where the flooding is very serious and there is no hope of remediation, it is necessary to plow and replant in a timely manner to make up for the losses caused by the disaster. You can choose to grow some fast-growing leafy vegetables, such as chicken hair, baby greens, etc.

Plough and replant fields should be sown early, phosphorus fertilizer should be increased, management should be strengthened, and early maturity should be promoted.

The drought tolerance of corn is still relatively strong, that is to say, corn can also be planted in some places where there is no water, as long as it rains a few times a year, like we plant corn in the mountains, there is no water source at all, it depends on rain or dewdrops, so as long as it is not high temperature and drought, then corn can survive.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: After the corn is sown, the ground is flooded for two days before there is no water to emerge seedlings, and after the corn is sowned, the ground is flooded for two days before there is no water and the seedlings cannot emerge; As long as the corn seeds are not soaked for more than 12 hours, they can emerge.

If the corn seed is just sown, it can still come out if the water is flooded, if the corn is germinated, the water will not go down for a while and a half, so the corn seed can not come out The corn seedling stage can be soaked in the water for two to three days, if the temperature is high, it will not work, and it should be drained in time. Due to continuous rainfall, the soil is compacted and the crop roots are in a state of suffocation due to lack of oxygen.

Dear, I'm honored to have your question to provoke Sun Yo The information that the teacher found for you here is: After the corn is sown, the ground is flooded for two days before there is no water, can the seedlings come out of the shed, and the corn is flooded in the field for two days after the corn is sown, and the seedlings cannot emerge without water; As long as the corn chain leads the seeds, they can emerge if they are not soaked for more than 12 hours. If the corn seed is just sown, it can still come out if the water is flooded, if the corn is germinated, the water will not go down for a while and a half, so the corn seed can not come out The corn seedling stage can be soaked in the water for two to three days, if the temperature is high, it will not work, and it should be drained in time.

Due to continuous rainfall, the soil is compacted and the crop roots are in a state of suffocation due to lack of oxygen.

If this is the case, it stands to reason that the water in the corn field has dropped, and the corn has not changed, so it should not die.

Corn is a crop that is both afraid of drought and intolerant to flooding, and when soil moisture exceeds 80% of the maximum water holding capacity, corn will be stunted; After being flooded for 3 days, the survival rate of corn is basically very low.

Therefore, if the water level drops immediately after the rain, it will not affect the corn, but will promote the increase of corn yield, but once the water is accumulated for more than 3 days, then the corn will waterlog.

After heavy rainfall, if there is standing water in the corn field, it should be discharged as soon as possible to reduce the humidity in the field.

Judging by your description, there are not many problems with corn growth at the moment.

Let's pay attention to it later.

It doesn't matter if you don't die, the yield will definitely be reduced, and if you die, it depends on the maturity now.

After the cornfield has been flooded, then as long as he grows on the plants, then he is fine.

In recent days, due to excessive rain, our family's corn field has been flooded with branches. On the first day of the flooding, we were worried about the impact on our crops. However, after a few days of observation, we found that the crops seemed to be fine and were growing well.

Flooding has a great impact on crops, but it also makes us pay more attention to the environment in which our crops grow. First, flooding helps reduce insect infestation in cornfields, as flooding suppresses insect activity. Second, flooding also increases the nutrient content of the corn field, because flooding will squeeze the nutrients under the corn field upwards, so that the crops can absorb the nutrients more fully.

Although flooding can also have a negative effect on crops, we should see the benefits of flooding. Flooding can reduce insect infestations and increase nutrient content, and we should protect crops as well as the environment. Let's work together to make the crops grow stronger!

Corn crops should not be flooded for more than 3 days.

Waterlogging for more than 3 days will affect yields. Corn is a crop that requires a lot of water, but is not tolerant to waterlogging, and when the soil moisture exceeds the maximum water holding capacity of more than 80, corn is stunted.

The corn grip is poor due to waterlogging, resulting in hypoxia, resulting in difficulty in root respiration, and at the same time, the reduction of toxic substances leads to root poisoning and death. The flooding should not exceed 1 day at the seedling stage, 1 2 days at the panicle stage, and 2 3 days at the flowering stage. The seedling stage is the least tolerant to waterlogging.

Flooding of maize at different times will lead to a decrease in yield, but the decline is related to the growth period, the degree of flooding, and the length of flooding. At the 4-leaf stage, the yield can be reduced by 10 30 after 5 days of watering.

Yield of corn planting:

1. When the corn seedlings grow to 5 leaves, cut off all the plants above the first leaf with a blade, and remove the first leaf by hand. Because the corn seedlings are still growing below the soil surface, the plant will grow new leaves the next day after the leaves are removed. After leaf picking, the corn is thicker, steady, and less bald than the stalk without leaves, which can increase the yield by 30.

2, the tip of the corn in the whole field of silking in the late stage of the mu hu, between the upper part of the plant that does not have a knot stick and the third leaf to fold into a corner by hand, but can not be broken, after the break of the four fast bark to five days that is, the rod is drawn, and the broken stem node can generally be restored to its original state in two to four days. In practice, this method can reduce the empty stalk ratio of maize from 15 40 to 2 5, and increase the average yield per mu by 15 25 kg.

Nothing happened after the cornfields had been flooded for a few days.

However, after a long time, due to long-term blistering, the oxygen content in the soil will become very low, and the microorganisms in it will ferment, which will cause the root system of the plant to rot.

Therefore, after being flooded for about 3 to 5 days, the empty water should be discharged, and after the exposure to the sun, the potatoes will not have any effect.

Summary. Water will drown the corn.

Water will drown the corn.

1. Timely drainageOnce the water in the field is found, remove the water in the field and the water in the cultivated layer as soon as possible, reduce the time of water accumulation in the field, and prevent the occurrence of root rot and stem base rot caused by water accumulation in the field and poor soil aeration. 2. Timely sorting out the corn that has fallen due to the disaster, and the corresponding treatment methods should be taken according to the degree of lodging: first, for the plot with a light lodging degree and lodging in one direction, the stem nodes of the corn near the ground can quickly take root, relying on their own lateral bending to resume upward upright growth, if the number of broken plants is not large, it is recommended to let it recover naturally; Second, for the plots that are flowering or scattered pollen within 3 days, they should be straightened and straightened as soon as possible; Third, for plots with taller plants, pollinated and more stems, the finch should not support the seedlings to prevent the root system from being torn off and causing plant death; Fourth, for the lodging is serious and has not yet been pumped, when the ground is slightly dry after the rain, the method of artificial straightening is adopted.

For plots with broken stems, the broken plants should be removed from the field as soon as possible to avoid rotting and affecting the normal plant growth.

3. After the rainstorm and flooding, the dryland crops are compacted and the soil is poorly aerated and the water, gas and heat are seriously out of balance, and the soil is loosened after drying in the field for 2 to 3 days, so as to break the compaction and prevent the roots, so that the roots of the plants can resume normal growth as soon as possible to prevent the lodging of the later stage. 4. Timely fertilizer waterlogged corn after flooding, a large amount of nutrients in the soil are lost, should be timely supplemented with chemical fertilizer, mainly to apply fast-acting nitrogen fertilizer (urea), and supplemented by phosphorus and potassium fertilizer, there is a lack of parts can also be supplemented with an appropriate amount of micro-fertilizer. The amount of fertilizer should be determined according to the degree of damage of the plant, soil fertility and crop growth period.
