How long can corn withstand flooding, and does the state have subsidies if corn is flooded

After flooding, it is necessary to apply fertilizers such as urea and nitrogen fertilizers in time. Since the peak growing season of corn is in summer, it is necessary to pay attention to the following matters: (1) Rush to sow early:

According to the author's observation for many years, the summer corn sown or transplanted a few days before and after the "Xiaoman" solar term matures early, is less affected by drought or flood in the later period, and the damage of borer is much lighter. Therefore, early sowing and early planting are the first choice to seize the high yield of summer maize. (2) Strengthen field management

Before live broadcast or transplanting, draw the "three ditches" of the field dam. To prevent stagnant water from becoming waterlogged, an appropriate amount of pesticides should be used to control underground pests when sowing. After the emergence of seedlings, check the seedlings in time to fill the gaps, control caterpillars, especially bugs, to ensure that the seedlings are full and strong.

3) Timely topdressing and weeding: the bottom fertilizer should be sufficient when sowing, and the seeds can emerge smoothly. After the 6-leaf stage, top dressing should be re-applied, and the nest should be discarded with high-quality compound fertilizer.

In addition, urea is used to drench with fecal water; Manually tear or use herbicides that do not hurt corn to control weeds and protect seedlings. (4) Late pest control: flowering and fruiting period, high humidity, heavy occurrence of diseases and insects, should be observed in time, dampness, timely symptomatic application of pesticides to prevent and control various pests and diseases, focusing on the prevention and control of rice borer that harms corn, sowing late summer corn, spraying the ears once with a large number of Lesben plus insecticidal double doses during the silking period of the ears, focusing on the top.

5) Reasonable dense planting: summer corn plants are tall, and sowing too dense is easy to cause shade, empty poles or lodging. And aggravate the moisture damage, it should be slightly thinner than spring corn planting.

6) When harvesting, the pulp should be completely dry and mature, and harvested when the weather is good, so as to avoid the harvest accumulation for too long, and dry in no weather, resulting in mildew loss. During rainy periods, you can leave the pole to delay the harvest and reduce undue losses.

Corn has different resistance to flooding during different growing seasons.

At the seedling stage, the corn plant has a weak ability to tolerate waterlogging, and can not exceed the day of flooding, if it is flooded for a long time, it will lead to the growth of corn is hindered or even killed. During the growing period, the flooding time should not exceed 3 days at most, and if it exceeds 3 days, the yield of corn will be greatly affected.

Overall, maize's tolerance to flooding varies depending on the growing season and water conditions. During the rainy season or when irrigation is excessive, special attention needs to be paid to drainage to avoid flooding of corn.

Legal Analysis: Corn is flooded and the state has subsidies. At present, the financial premium subsidy basically covers the main bulk agricultural products, covering planting, breeding, forestry, etc.

Agricultural insurance can enable insured farmers to receive economic compensation in a timely manner after suffering disasters within the scope of insurance liability, and can ensure the stability of farmers' lives by transferring and diversifying risks and paying compensation. It will help to ensure the continuous stability of the agricultural production process, so that the large amount of uncertain agricultural risk losses can be converted into small fixed agricultural insurance premiums.

Legal basis: Article 12 of the Regulations of the People's Republic of China on Agricultural Insurance After receiving the notice of the occurrence of an insurance accident, the insurance institution shall conduct an on-site investigation in a timely manner and verify the damage to the subject matter of insurance together with the insured. Where agricultural production and operation organizations, villagers' committees, and other units organize farmers to take out insurance, the insurance institutions shall publicize the results of the investigation and damage assessment.

In accordance with the provisions of the agricultural insurance contract, the insurance institution may adopt sampling methods or other methods to verify the extent of the loss of the subject matter of the insurance. Where sampling methods are used to verify the extent of losses, it shall comply with the sampling technical specifications provided for by the relevant departments.

Legal analysis: Yes, you can apply for subsidies from the relevant local departments, and the state generally has subsidies for agricultural losses.

Legal basis: Interim Measures for Social Assistance

Article 2: The social assistance system adheres to the bottom line, emergency relief, and sustainability, and is linked to other social security systems, and the level of social assistance is commensurate with the level of economic and social development.

Social assistance efforts shall follow the principles of openness, fairness, impartiality, and timeliness.

Article 3: The civil affairs departments are to coordinate the establishment of the national social assistance system. Departments such as for civil affairs, emergency management, health, education, housing and urban-rural construction, human resources and social security, and medical security are to be responsible for the corresponding social assistance management efforts in accordance with their respective duties.

Local people's ** departments such as for civil affairs, emergency management, health, education, housing and urban-rural construction, human resources and social security, and medical security at or above the county level are responsible for the corresponding social assistance management work within their respective administrative regions in accordance with their respective duties.

The administrative departments listed in the preceding two paragraphs are collectively referred to as the social assistance management departments.

Article 4: Township people's ** and neighborhood offices are responsible for accepting, investigating, and reviewing applications for social assistance, and the specific work is to be undertaken by the social assistance handling agency or handling personnel.

Villagers' committees and residents' committees are to assist in the work of social assistance.

Corn at 20 degrees moisture can be stored for a long time. If the fresh raw corn is stored in the freezer, it can generally be stored for about a year, and the preservation method is to peel off the corn husk, leaving two or three layers of skin in the most celery wheel godCorn whiskersThere is no need to remove it, so that it will stay fresh for a longer time.

Corn can be stored in the refrigerator, if it is stored in the refrigerator, it can generally be stored for about a week without spoiling, but be careful not to peel off all the outer skin of the corn, otherwise it will lead to water loss.

How to preserve corn:

Hanging preservation: Corn can be tied together and hung in a ventilated place, which is an ancient method of preserving corn by drying it for a long time.

Corn kernel preservation: Fresh corn is broken down into granules, and then placed in a low temperature environment for preservation, which can also achieve the effect of long-term preservation.

Nitrogen preservation: If you want to preserve corn for a long time, you can also put corn in a bag full of nitrogen, which is based on the principle of isolating the air to preserve.

Corn is flooded like leaky water, not for a long time, it can still be relieved, if the time is relatively long, the roots and leaves are rotten, it is impossible to recover the spring come, can only plant the slag source of the next crop.

Yes, you can. It is necessary to drain the water as soon as possible, carry out the loosening of soil and soil cultivation in time, break the compaction, and increase the application of fast-acting nitrogen fertilizer.

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.

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!
