Do you need to turn over the soil when the corn is half the size? What does turning the soil do?

Generally speaking, corn promotes early maturing plots, mainly late-maturing varieties (there are many spring maize planting areas), and the purpose of promoting early maturation is to prevent maize from not maturing before frost (yield reduction), promote maize growth and development through field management, and promote early maturation (more than 5-6 days). During the whole growth period, promoting corn maturity is a series of processes, and in the later stage, the measures to promote early maturity mainly have the following three points, but there are also certain limitations, which can be operated according to their actual conditions.

When corn grows to the later stage, the field is relatively dense and not suitable for manual operation, but if the friends who plant large and small rows can go to the field to weed, it can promote soil permeability, increase temperature, facilitate the activity of microorganisms in the field, strengthen corn root respiration, reduce premature corn aging, and achieve the purpose of early maturity. Do not get too close to the roots during the turning period, be careful not to cause damage to the roots, pay attention to the action, and minimize the damage to the leaves. Weeding is mainly based on weeding, and the grass is also treated together, and the workload is too large.

Because the above requires labor, it is suitable for farmers who plant a small area to plant a large area, and the labor cost is too high.

Only one ear of fruit left for a corn plant is fine. That is to say, although it is the first ear, in the actual planting process, due to weather factors, nutritional factors, etc., the second or third ear of the corn plant develops and "competes" with the first ear. In this case, unnecessary ears should be removed in timeIn addition, there may be bottles of wine, medicinal wine, small plants, radishes and ears of plants in the field, it is recommended to remove them all, on the one hand, it can not only improve water-saving fertilizers, but also improve the ventilation and light transmission of the field, which are conducive to the early maturity of corn.

I have never heard of grinding corn when ploughing the land, planting Shandong, and corn. Basically, wheat is sown directly after harvesting, and it is planted in two seasons a year, and the land must be cultivated when the wheat is grown. Corn is planted in the Northeast for one season, and when corn is planted the next year, it must be turned over and over again.

The Shandong side usually does not turn over the ground. The wheat harvest is followed by summer, when the rain is heavier and the land is wet. Most of the wheat straw is returned to the field, and the straw is relatively broken, so there is no need to turn the corn and sow it directly.

The straw of wheat usually rots almost within two months, and there is also a downside to the land that has not been turned. In other words, some places where the straw is thicker will affect the corn sprouts and need to be cleaned by yourself. There is another drawback.

When the corn is first watered, the straw in the field has not yet rotted, so it is slower to water, and these straws can hinder the flow of water.

The main function of turning the soil is to loosen the soil, improve the breathing ability of the corn roots, and make it grow more robustly.

Not only corn is grown, but other crops are also necessary to be ploughed before planting. If you sow the original crop, you will find that the soil's moisture retention capacity, fertilizer use, root growth and aboveground growth will be affected to varying degrees.

Nowadays, no-tillage planting technology is being promoted in many regions, and I think that for the current agricultural planting situation in China, the blind pursuit of cost reduction and ignoring the ability of soil to resist drought, yield and quality is not worth the loss. It is said that the planting method of the previous year is not only a habit, but also has a certain scientific support.

It depends on the situation, if you care about it, you will go to turn the picture for him, and you don't care about waiting for him to grow on his own (in the past two years, the people who have gone out to work here have not planted much, and corn and the like are all planted and then born to raise), turning the soil can make the soil loose, ventilate the root system of corn, and bury the weeds growing next to it as fertilizer when turning the soil, and also avoid the corn being robbed of nutrients by weeds.

It is necessary to till the soil during the corn planting process, because the soil will be more fertile after the doubling.

It is necessary. Ploughing the handshake and turning the pina will bring immeasurable value. Continuous no-tillage is not possible, tillage can effectively prevent soil compaction, which is good for increasing yields, but it does not need to be ploughed every year, and organic fertilizer can improve the base soil.

It is necessary to plough the soil, and the water absorption and air permeability of the soil will be better after ploughing the soil, which is more conducive to the absorption of corn.

When the ground is dry, what will be the effect of planting corn in a deep depth when the dry soil is separated.

1.This allows corn to take deeper roots. Loose soil, topsoil planting years too much, deep ploughing can alleviate the late cracking of the soil plate 2

This allows the soil to retain more water and provide more nutrients for corn. 3.The corn fertilizer will be better in the year of sucking and closing, the utilization rate of deep fertilizer is higher, farmers are used to fertilizing first, and then ploughing the ground, the more fertilizer covers the soil, the less volatilization.

Summary. Hello, dear, I'm glad to answer for you, corn doesn't need to be dug if it doesn't grow in the soil. You don't see signs of corn growth for a long time after sowing and you can find the cause of the problem by examining factors such as soil, seeds, and climate.

Hello, dear, I'm glad to answer for you, corn doesn't grow in the soil and doesn't need to be answered. You don't see signs of corn growth between your pancakes long after planting, and you can find the cause of the problem by examining factors such as soil, seeds, and climate.

Climate. Expansion related: Let the space give the seeds to grow corn need to pay attention to the following:

Choose the right land: Corn needs plenty of sunlight and moisture, so it's important to choose the right land to grow it. The soil should be soft, fertile, well-drained, and have the appropriate depth of tillage.

Maintain the right temperature and humidity: Corn is suitable for growing in a warm, humid environment. During planting, timely watering, fertilization, and weeding are very important.

Planting suitable varieties: According to different climatic conditions and soil quality, select suitable corn varieties for planting. Drought-tolerant, adaptable, and high-yielding high-quality varieties are usually selected.

Reasonable fertilization: Before sowing, an appropriate amount of basal fertilizer should be applied according to the soil conditions, and nutrients such as nitrogen, phosphorus, and potassium should be applied after sowing or at the same time to promote the growth and development of corn. Pay attention to the prevention and control of pests and diseases

Corn is susceptible to various pests and diseases, so it is necessary to take timely control measures, select appropriate pesticides for spraying, and adopt biological control methods.

It has been planted for + five days, and the teeth are not unearthed.

Low temperatures, unsuitable soil, and improper sowing depth can all be caused.

Can it come out. Dear, you can also look at the quality of the seeds, the quality of the seeds themselves will affect germination.

You can start by growing a few seeds at home and see if they sprout.

Can a tooth come out?

OK. What area are you in.

Ordos City, Inner Mongolia.

Dear, it shouldn't have much to do with your temperature I'll check the temperature is okay, you first cultivate the seeds to see if they germinate.

The seeds are all teeth, but they are planted a little early.

Kiss, that's the first few days when the temperature was low, and it will be fine when the temperature rises.

Summary. Corn is a high-yielding crop, and its yield level is closely related to the level of soil fertility. In the high-yield and high-efficiency fertilization measures of corn, the first thing is to widely apply organic fertilizer to improve soil fertility, and the amount of organic fertilizer input per mu should not be less than 4000 kg.

Hello, this can be grown.

Hello, you can use more base fertilizer before planting corn, and choose potassium sulfate release fertilizer. Due to the relatively high controlled-release fertilizer, the controlled-release corn on the market is now made of a mixture of slow-release fertilizer and compound fertilizer, and the cover must pay attention to the seed fertilizer isolation in the early process of the fertilizer, and the fertilizer is 6 8 cm on the right side of the seed fertilizer, and the fertilizer is on the side of the corn seed.

Maize is a pure and high-yielding crop, and its yield level is closely related to the level of soil fertility. In the high-yield and high-efficiency fertilization measures of corn, the first thing is to widely apply organic fertilizer to improve soil fertility, and the amount of organic fertilizer per mu should not be less than 4,000 kg.

Summary. Corn grass germination time is generally 5 to 10 days after sowing, and the fastest growth time is two months. Scientific name of corn grass:

Fragrant green orchid, multi-branched, annual herbaceous plant. It is widely cultivated in China. Generally speaking, as long as the temperature of the growing environment is not lower than 12, the growth cycle is 200 days.

About 2 days. I'm sorry I don't understand, but can you elaborate on that?
