When is corn sown? When is corn sown?

Are you talking about spring-sown corn or summer-sown corn? It is sown around the left and right for spring sowing, and sowing in July for summer sowing.

Sow in the spring, and you can have a good harvest in the summer.

According to the climate of different places, spring corn in the north is now the sowing season, and summer corn is sown after the wheat harvest.

Corn is divided into spring corn and autumn corn, spring corn is sown in late April and early May, and autumn corn can be sown no later than mid-July.

Corn is divided into spring corn and autumn corn, spring corn is sown in late April and early May, and can be harvested in late August; Autumn maize should be sown no later than mid-July and harvested in mid-to-late October.

Maize is an annual herbaceous plant of the genus Maize in the family Poaceae. Aliases: maize, cob, baogu, rice, millet, jade, bud rice, Northeast Liaoning dialect is called pearl grain, Chaozhou dialect is called barley kernel, Cantonese is called corn, Hokkien is called panwheat.

Corn is an annual monoecious cross-pollinating plant with tall plants and strong stems, which is an important food crop and forage crop, and is also the highest total crop in the world, second only to rice and wheat in terms of planting area and total yield.

It is cultivated all over the country. It is widely cultivated in tropical and temperate regions of the world and is an important cereal.

Corn has always been known as a longevity food, rich in protein, vitamins, trace elements, fiber, etc., and has great potential for the development of highly nutritious and biologically functional foods. However, due to its complex heritability and rich variation, there are shortcomings such as long cycle, excessive coefficient of variation, and affecting the growth and development of offspring in the conventional breeding process, and modern biological breeding technology not only overcomes the above shortcomings and deficiencies, but also improves the breeding speed and quality.

Corn is sown in April-May in the spring and in July in the fall.

Corn is an annual herbaceous plant of the genus Poaceae, also known as bud grain, bud cob, maize, pearl rice, etc., which is an important food crop and feed crop in China, and is planted in the north and south of China. Corn is very popular among consumers in the market, it is divided into spring corn and autumn corn according to the time of planting, spring corn is sown between April and May, and can be harvested in late August. At this time, the climate is more suitable, the temperature and humidity are more suitable, and the germination rate for sowing is relatively high.

Autumn maize should be sown no later than mid-July at the latest, and harvested in mid-to-late October. In the life of maize, according to morphological characteristics, fertility characteristics and physiological characteristics, it can be divided into several different growth stages, each stage includes different growth periods, and these different stages and periods have their own characteristics and are closely related.

Precautions for corn planting

1. Soil selection: Choose soil rich in organic matter, loose and well-drained. Corn has high soil requirements, and sufficient nutrients and suitable soil pH can promote growth and yield.

2. Water management: Sufficient water is needed during the corn growth period, especially in the booting and filling stages of rapid growth. Make sure the soil is moderately moist, but avoid waterlogging.

3. Fertilization: Reasonable fertilization according to soil quality. Organic fertilizers should be applied appropriately before sowing to increase soil fertility and improve soil structure. In the process of corn growth, an appropriate amount of nutrients should be supplemented according to the required nutrients of the plant.

4. Weed control: take control measures in time to prevent the competition of weeds for corn growth. Weeds can be managed by hand weeding, mulching the lawn, and spraying herbicides.

5. Pest control: closely observe the condition of corn plants and leaves, and take timely control measures once pests and diseases are found, such as spraying appropriate pesticides.

6. Interval and density: According to the variety and soil conditions, the interval and density of corn should be reasonably determined to ensure that each corn plant gets enough nutrients and space.

8. Natural factors: pay attention to the weather forecast and arrange agricultural work reasonably. In the event of extreme weather (e.g., strong winds, heavy rain, drought, etc.), protect the corn plant to reduce losses.

Spring corn is generally sown from late April to early May, and summer corn is roughly around June.

After the corn is sown, only when the ground temperature of 10 cm is stable through 12, the effect of germination in 7 days will be achieved, if the ground temperature does not reach this temperature, the corn seed is in the soil for too long, the germination rate will be low, and the seeds that barely germinate will also form weak seedlings. Therefore, corn sowing must be based on temperature changes, timely grasp of sowing time. Do not sow too early, corn is not sown earlier the higher the yield.

If you plant too early, the yield will be low.

Only when the local wheat is planted in the first 15 to 20 days of the harvest is the period when the corn yield is at its highest. In addition, it is necessary to select suitable varieties, and maize varieties should not only be excellent varieties that adapt to the local climate, but also varieties with high comprehensive characteristic indices such as lodging resistance and stress resistance.

How to grow corn:

1. Soil preparation and fertilization.

Before corn planting, you need to prepare the land and fertilize it, select a suitable plot, and then turn the soil deeply, with a depth of about 35 cm, so that the soil becomes loose and breathable, and apply a sufficient amount of fertilizer in the soil as the base fertilizer, and ridge after the fine rake is leveled, so that you can prepare for planting.

2. Sowing and planting.

Select the appropriate variety of corn grains, sow them into the soil according to the row spacing of 65cm, plant spacing of 18cm, and the depth of 5cm, and need to be watered appropriately after sowing to keep the soil slightly moist, so that the corn can quickly emerge and grow, and it should pay attention to the time after the seedlings are replenished.

3. Maintenance management.

After corn planting, it needs to be well maintained and managed, it needs to be cultivated and weeded regularly during the growth period, and it is also necessary to apply thin fertilizer to it regularly, and it is necessary to pay attention to the prevention and control of pests and diseases during the maintenance period.

Corn is more suitable for planting in the month. The most suitable temperature for corn sowing is 10 12, learn from the law of temperature changes in the past month is a good time for corn planting, and the corn is a short-day sun-loving crop, and the sunshine is conducive to growth in 8-12 hours. Corn can be flowered late if it has long days, but it can bloom in short days.

Therefore, farmers should seize the time and sow seeds when the soil temperature is stable.

Growth and development of cornThe life of corn - from sowing to new seed maturity, through planting in germination, seedling, jointing, booting, tasseling, flowering, silking, fertilization, filling until the new seed matures, the whole growth and development process is completed.

Summary. Hello, spring corn is generally sown from late April to early May, and can be harvested in late August; Autumn maize should be sown no later than mid-July and harvested in mid-to-late October. Due to the certain differences in temperature in various regions, the planting standard can be based on low temperature above 10.

Hello. Round corn is sown in several months here in Beitun.

Corn sowing in the North begins on April 25.

How long is it growing.

If 5 17 comes out, can it still ripen.

Corn generally matures in September-October, and the ripening time can vary slightly.

I'm 10 20 received.

But immature, what is the reason for this. Weather.

Corn is one of the widely planted food crops in the world, and it is called differently in different regions, such as corn, cob, corn, maize, etc., of course, different regions, corn has different planting times, so, when is autumn corn sown? When is the late sowing time for autumn corn? Let's find out together.

Corn sowing time as far as possible to adopt rain-fed dry farming technology, in the suitable sowing period for rain sowing, if there is no rain, sprinkler irrigation or canal irrigation, there is micro-drip irrigation conditions to make the best use.

The suitable sowing date of spring maize in cold and cool mountainous areas is from late April to early May, and in plain areas it is in mid to late May.

In the northern mountainous areas of Yanqing, Miyun and Huairou, when the temperature of spring maize in the 5-10 cm soil layer is stable to 10 (according to the current monitoring), and the relative moisture content of the soil is about 65%, it should be sown as soon as possible. If the soil moisture is low, it is necessary to wait for rain to sow seeds.

Moisture grabbing and sowing should be deep and shallow covering the soil, so that the seeds are on the wet soil, and suppressed after sowing to ensure that the seeds are in contact with the wet soil.

When can corn not be sown after 1Northeast China: The determination of corn sowing date, the first thing to consider is the low temperature chilling injury at the flowering stage, the slow growth and development in the cool summer, and the influence of low temperature chilling injury and early frost in the autumn at the filling and maturity stage.

Sowing can be done when the temperature rises to 7-8 in spring, early maturing varieties are used in cold years, and mid-late maturing varieties or late maturing varieties are selected in warm years.

Early-maturing varieties are used in the northern region, and mid-late maturing varieties are selected in the central and southern regions.

Early maturing varieties are used at high altitudes.

2.North China: wheat stubble corn sowing period should not be too early, so that wheat, corn symbiosis period is too long (generally 25 days is appropriate) can not be sown too late, to ensure that wheat harvest corn has entered the ear differentiation stage, so that the critical period of corn yield formation has a good growth environment, but also to make corn growth in the later stage is not affected by low temperature, mature and high yield.

3.In the autumn in North China, there is often a cold autumn weather with low temperature and rain or early cooling (late August to September), which makes the corn greedy for green and late ripening, the grain maturity is not good, and the yield is not high.

The reason for this is that the seeds are sown too late and the varieties are not used properly.

According to the long-term weather forecast, varieties with different ripeness should be used for different year types (warm autumn, cold autumn) to ensure that different year types can obtain good harvests.

4.Southwest China: Spring maize sowing should pay attention to two problems, one is the early spring warming in southwest China, and the use of early spring heat conditions to avoid the impact of spring drought, early summer drought and high temperature.

Second, it is necessary to pay attention to the "late spring" caused by the "inverted spring cold" weather, and should rush to sow seeds at the end of the cold tail to avoid the impact of the spring cold.

5.South China: Especially in Hainan, the determination of the sowing date of corn in the south in winter should take into account the low temperature of corn flowering and pollination period from January to early February, and it is advisable to sow from October 15 to November 15, and should not be postponed to late November to early December.

6.Corn is divided into spring corn and autumn corn, spring corn is sown in late April and early May, and can be harvested in late August; Autumn maize should be sown no later than mid-July and harvested in mid-to-late October.
