What is the reason why corn dies when it is ripe, and why corn is dying when it is about to ripen

Corn dies when ripe.

1. It may be that the weather is dry, and a lot of water is needed to mature, and the nutrients cannot keep up, so you can water it properly.

2. It may be too much rain and continuous cloudy days.

The roots of the corn are broken, causing the corn to wither, pay attention to timely drainage.

3. There may be insects, which bite the corn orange and cause the corn to die, so check and spray in time.

There are many types of maize diseases, the epidemic factors are complex and changeable, the control methods should be diverse, and the disease management must start from the agricultural ecosystem as a whole, and change the single disease control to the direction of systematic comprehensive control. It is necessary to change the focus on protecting corn to protecting the farmland ecosystem, develop in the direction, and give full play to the organic coordination function of various key technologies.

1. Dynamic monitoring of pathogen physiological species variation can timely grasp the frequency of virulence of pathogen races and the dynamics of pathogen variation, which can provide a scientific basis for disease resistance breeding and rational distribution of varieties, improve the predictability of disease resistance breeding, and avoid huge losses caused by the loss of variety resistance caused by pathogen variation.

2. Breeding and utilization of disease-resistant varieties and rational distribution of varieties.

The breeding and utilization of disease-resistant varieties is the most fundamental, economical, safe and environmentally friendly measure to control maize diseases. Screening resistance from cross lines, discovering disease resistance genes, creating disease resistance breeding materials with strong resistance and excellent agronomic traits, and then breeding new disease resistance varieties, which are popularized and applied in production. Carry out a reasonable layout of the promoted varieties, and plant hybrids with different disease resistance types in a certain proportion in the same ecological region to avoid the single planting of varieties.

3. Agricultural cultivation and disease prevention measures.

timely sowing, the implementation of corn-soybean, corn-wheat rotation, change the ecological conditions in the field; Rational formula fertilization, timely increase the application of K fertilizer, improve the resistance and defense ability of corn to pests and diseases; For the prevention and control of soil-borne diseases, the use of seed coating agents can achieve twice the result with half the effort.

It may have something to do with the soil, and if it doesn't have anything to do with the seeds.

Choose stress-tolerant corn seeds for the next year, and don't covet cheap seeds.

If the unripe corn is killed by frost, the corn that is saved in time can actually be cooked. If the sowing date of corn is delayed, the growing period will be relatively long. If the temperature is too low, you can choose to raise the temperature in time.

In the case of good temperature, the corn will slowly mature, and there is a possibility of saving it in the later stage. We must not wait until the corn has stopped growing to save it, it is already too late. Be sure to pick the unripe corn in time and use it to feed the family's livestock.

Corn mainly relies on the leaves to receive sunlight for photosynthesis during the ripening stage.

During this process, it is important to ensure that the corn can absorb the temperature. If normal corn has green leaves when it grows, there is no need to worry, and if there is a change in color, it needs to be adjusted. If the temperature is too low, the leaf will reduce the amount of photosynthesis it absorbs, and it may also stop.

The temperature should not be lower than 20, otherwise the corn leaves will start to die. If you find that the sun is not sufficient, you can also choose to control it with a greenhouse. <>

Corn can be harvested before and after frosting, and a good harvest must be carried out in time. If a farmer grows corn for a year and ends up with no harvest at all, that's part of the biggest loss. If the planted corn is not harvested in time, the corn will stop developing after frosting and the yield will be reduced.

You can fertilize and water more before you plan to let it absorb better. When it grows well, you can choose to have a good harvest so that there will be no losses. <>

Overall, corn is very nutritious and can be eaten not only in stewed soups but also steamed. Corn is a coarse grain.

Therefore, if the farmer has nothing to do in his hometown, he can choose to plant some corn. Winter weather is colder, and corn is the least frost-tolerant. In the process of planting, we must pay attention to the ways and means, and we must not be confused.

No, because the frost has a great damage to the corn, and the cells of the corn have been killed, and the corn cannot absorb nutrients normally, so it cannot mature.

Under normal circumstances, it is not possible to mature, because the corn has stopped growing, and the long-term frost has also affected their root system, resulting in the inability to absorb nutrients in time and continue to grow.

It will not grow anymore, only when it dries slowly, if there is frost, it means that the temperature has fallen below 16 degrees, and the plant will not be green at this time, and it will not continue to grow.

Infected with bacterial wilt: Once corn is infected with bacterial wilt, it dies in two to three days or five to six days. Improper watering:

Too little watering at the grain filling stage and wax maturity stage of the plant affects the growth and development of maize. Pest infestation: Corn borer will eat the stems and leaves of the plant, destroying the original tissues of the corn.

Maintenance method: Regular cultivation and weeding.

1. Infected with bacterial wilt

The reason for the death of corn is that it is infected with bacterial wilt, when the plant is in the filling stage to the mature stage, it is easy to be infected with bacterial wilt, especially before and after the milk maturity period is the peak period of the disease, and a bird cave hall is infected, less than two to three days, more than five to six days will wilt and die.

2. Improper watering

In the grain filling period and wax maturity period of corn, it is necessary to water in time to keep the soil moist, if the watering is insufficient, resulting in a lack of water in the soil, it will affect the growth of the plant, so that there is a situation of dead trees, especially in the grain filling period, the amount of watering should be strictly controlled, neither more watering nor less watering.

3. Insect pests

Corn borer is easy to occur from seedling stage to maturity stage, corn borer will eat the leaves and stems of the plant, destroy the original tissue of the corn, resulting in the plant can not grow and develop according to the normal growth state, and in severe cases, the corn wilts and dies.

4. Maintenance method

In the process of maintaining corn, it is necessary to carry out reasonable trembling watering according to each growth stage of the plant, and at the same time do a good job of drainage measures in the rainy season, reduce the humidity in the field, and carry out weeding in the hidden period, and spray 10% of the imidacloprid 1,000 times liquid on the plant to control the corn borer.

If the autumn corn suddenly frosts, it may freeze and die. Many of the foundations are frosted and frozen so early, but if the corn is ripe and the cobs are broken, he will slowly die. If you plant too late, and by the time the frost freezes, your corn cob is not ripe, then it is very bad, because by then he is close to death, and the corn cob will not be ripe.

Below or above 35 degrees Celsius, growth should stop or grow slowly.

When the temperature is below 15 degrees, the jointing chamber rubber is stopped.

In the 5-10 cm deep bond soil, the temperature is constant and bright macro is set at 10-12 degrees Celsius can be sown; When the temperature is 25-35 degrees, corn seeds are most suitable for germination; The temperature is 18-20 degrees Celsius, which is most suitable for seedlings.

<> corn sprouts are prone to frost damage in an environment with a temperature of 2 degrees Celsius, and in severe cases, they will freeze to death. Corn seeds are easy to powder in the environment below 4 degrees Celsius, corn likes high temperatures, 25-30 degrees Celsius is the suitable growth temperature, the temperature above 18 degrees Celsius is the best temperature for the jointing stage, and 26-27 degrees Celsius is the best temperature from heading to flowering.
