What is the growth cycle of corn? Corn growth cycle

The growth period of corn is generally 95-120 days.

The growth period of jade is generally divided into early-maturing varieties, late-maturing varieties and medium-maturing varieties, and the growth period is different.

The growth period of corn is generally 100 to 120 days.

The growth period of corn is generally about 100 days, which varies depending on the variety and region.

The growth period of corn is, technically speaking, the growth period, from the time of sowing to maturity of corn. The growth period of corn is related to two factors, one is the characteristics of the variety, and the other is the environmental factors, especially the temperature, so the growth period of corn varies from 70 days to 150 days.

The growth period of corn will be affected by the seasonal climate, variety, etc., generally about 100 to 130 days, in this period, corn will go through the seedling stage, ear stage, flower and grain stage, fruit stage several stages.

The growth period of corn is 120 days.

The growing season of corn is generally 110 days.

The growing season of corn is generally about 60 days.

1) ultra-precocious, 70-80 days; (2) precocious, 81-90 days; (3) medium-early maturity, 91 100 days; (4) medium-ripe, 101 110 days; (5) medium and late maturation, 111 120 days; (6) late maturation, 121 130 days; (7) Super late ripening, 131 140 days.

Depending on the growth period and variety of maize, the growth period of maize is generally 100 to 120 days.

Corn is one of the main food crops in our country, with a wide variety of varieties and is cultivated in various places. So how long is the growth cycle of corn?

The growth cycle of corn is generally about 100-130 days, and there will be great differences between different varieties and different regions. For example, the growth cycle of corn in North China is about 100 days, and the growth cycle of corn in Northeast China takes about 130 days.

Its growth cycle is mainly divided into three stages: seedling stage, panicle stage and flowering stage.

The growth cycle of corn is early and late, generally about 118-125 days, after the beginning of autumn, I am afraid that the corn will not come up, and the corn will be killed by frost before it matures, so it should be planted before the summer in the middle and lower reaches of the Yangtze River.

In the middle and lower reaches of the Yangtze River, corn can be planted in two crops, and in the Yangtze River basin, spring-sown corn is generally sown at the end of March and early April, and can be picked in early to mid-July.

Autumn maize should be sown no later than mid-July and harvested in mid-to-late October.

The growth cycle of corn is about 100 days, the shortest is more than 90 days, and the longest is 120 days.

The growing cycle of maize is generally about 80 to 100 days.

Generally, it takes about 90 days from planting to maturity. Some cycles are about 100 days long, and now they are all live straw, that is, even if they are ripe, the straw is still green.

The normal growth cycle is 120 days.

The cycle is 120 days, and hot days grow fast.

The growing season of corn is generally between 80-120 days. Due to factors such as variety, climate, soil, moisture, fertilizer, etc., the ripening time of corn is different. Some corn varieties only require 100 days, but due to the factors mentioned above, the maize period is sometimes a few days earlier or a few days later, not necessarily exactly 100 days.

The maturity period of corn varieties is when various factors are normal before corn can reach maturity. If there are one or two reasons, the ripeness of corn changes. Corn planting tips 1

Planting time corn prefers to grow in a warm environment. If you want to plant, you first have to choose the right time to plant. According to the habits of corn, it is best to plant it in April-May in spring, and it can also be planted in mid-July.

It should not be planted too early or too late, otherwise the temperature is not suitable and it will easily lead to poor growth of corn plants.

The seeds are sown, and the swelling and germination of the embryo can be found on the first day;

A week later, the little shoots burst out of the ground; Under the sun's rays, the small yellow shoots gradually turn green;

Around 27 days, the seedlings gradually grow and begin to joint;

At 52 days, corn filaments begin to be drawn out, and male pollen appears at the top;

After about 90 100 days, after fertilization of males and females, the corn cob grows larger and larger, and the corn filaments slowly dry up or fall off, and grow into corn cobs.

The growing season of maize is divided into three stages. The time period from planting to jointing of corn is called the seedling stage, which is mainly rooted and germinated. The period of time when corn begins to grow tall and when it is tasseled is called the ear stage, during which the stems and leaves of corn grow rapidly.

The period from tasseling to fruit ripening is called the flowering stage, which is the time when corn begins to take shape.

Exact answers. Wheat is planted in autumn (late October to early November) and harvested in May of the following year.

There are many varieties of maize, which are generally planted in early summer and harvested in January.

The corn growth cycle is 95-120 days.

1. The growth cycle of early-maturing corn varieties.

The growth period is 80 100 days, and the accumulated temperature is required to be 2000 2300. The plants of this type of variety are shorter, the number of leaves is less, generally 14 16 pieces, the requirements for fertilizer and water conditions are not high, and the yield potential is not high.

2. The growth cycle of medium-ripe varieties of corn.

The growth period is 105-120 days, and the accumulated temperature is required to be 2500 2700. This type of variety has a wide range of adaptation areas, and the number of leaves is 18 20.

3. The growth cycle of late-maturing varieties.

The growth period is more than 125 days, and the accumulated temperature is required to be more than 2900. The plant is tall, the number of leaves is more, generally there are 21-25 pieces, the grain is larger, the requirements for water and fertilizer conditions are generally higher, and the yield potential is higher.

Precautions for corn planting

Corn has very important requirements for water and fertilizer, so when we choose the planting environment, we require fertile soil and irrigation and drainage, so we should open three ditches on the whole land, namely the main ditch, the surrounding ditch and the box ditch, and make the ditch communicate, the ditch does not accumulate water, and can be irrigated and drained.

Corn land preparation is best to plough frozen billets or plant a season of winter vegetables every other year, and when sowing corn in the second year, the soil is loose and dry, and the aggregate structure is good, which is beneficial to the growth of corn. If ploughing is not carried out, in the spring of the following year, it is necessary to choose to plough the land in time, apply farm fertilizer, keep the soil dry, improve the fertility of the land, and do a good job of clearing the weeds in the field.

The maize growth cycle is generally between 80 and 120 days.

Due to the combined influence of variety, climate, soil, moisture, fertilizer and other factors, the maturity time of corn is different. Some corn varieties only need 100 days, but due to some of the above factors, the corn maturity period is sometimes a few days earlier, or a few days later, not necessarily just 100 days. The maturity period of corn varieties is to reach the maturity stage of corn under the condition that various factors are normal.

If there are one or two reasons, the maturity of corn will change.

Corn planting tips

1. Planting time.

Corn likes to grow in a warm environment, if you want to plant it, then you first need to choose the right planting time, according to the habits of corn, it is better to plant in April and May in spring, and you can also plant in mid-July, not too early or too late, otherwise the temperature is not suitable to easily lead to poor growth of corn plants.

2. Soil preparation and fertilization.

When planting corn, it is suitable to choose loose, fertile and well-drained plots, before planting, the soil needs to be deeply turned, and an appropriate amount of fertilizer should be applied to the soil as base fertilizer, so that the soil can be more loose and fertile, and corn can grow more vigorously after planting.

3. Sowing and planting.

After digging a trench for the plot, prepare the corn seeds of suitable varieties, and then sow them into the soil according to a certain plant spacing, and cover a thin layer of soil after sowing, and water appropriately, so that the soil is in a slightly moist state, and soon the corn can emerge and grow.

Corn is mainly divided into three stages due to the variety, light, geographical latitude, planting depth, different growth cycles, and different planting times.

First, the seedling stage.

Second, the spike stage.

Third, the central part of the flowering stage such as Luzhong, northern Henan and other places: generally sowing in mid to late June, 5 7 days after the emergence of seedlings, early July is the three-leaf stage, mid-July is the seven-leaf stage, late July to early August jointing, mid to late August male pollination, September is the milk maturity period, late September to October is the mature harvest.

The growth cycle of corn has a certain relationship with climate and variety, for example, the growth cycle of corn in North China is about 100 days, while the growth cycle of corn in Northeast China takes about 130 days.

Compared with traditional rice, wheat and other food crops, corn has strong drought tolerance, cold tolerance, barrenness tolerance and excellent environmental adaptability. Corn has a high nutritional value and is an excellent food crop.

Hello! The growth cycle of corn is around 150 days. There are also some early-maturing varieties of corn that can reach 100 days.

Medium-term management, soil closure treatment before sowing so that weeds in the field can basically be controlled If there are more weeds in the field, post-emergence herbicides can be used before 5 leaves. This can be followed by a ploughing. Before jointing, nitrogen fertilizer was applied in combination with cultivator [conducive to mechanical operation].

During this period, pesticides should be sprayed according to the situation to prevent pests and diseases.

1. The growth cycle of sweet corn is about 100 days in North China and about 130 days in Northeast China.

2. Northeast China, North China and some parts of Northwest China are sweet spring corn that is harvested once a year;The North China Plain is dominated by summer maize, which is the second cropping in a year.

Hello Liaodan 1805,

Dingsheng 328,

The output of iron 2116 is outstanding and has a wide adaptability, which can be promoted according to the actual situation of each region.

You can take a look.

Question: I want to ask, which variety of sweet corn is better to plant on June 15 in Liaoning.

Guangliang Sweet 27 is a sweet corn variety introduced from Thailand, with tropical blood, the breeding place is in India, the heat tolerance is much better than that of ordinary sweet corn, and the cob is very large, the planting density is controlled at 2600-2800 plants, and the weight of the peeled cob can reach about 1 catty! The yield is very high.

2. Ruixian Sweet 211

Ruixian Sweet 211 is a variety with very good comprehensive performance, which is a rice grain type, with about 350-400 grams of fresh buds, crisp taste and high sweetness. The variety has wide adaptability, strong resistance to stress, and vigorous growth.

It takes about 110 to 120 days from sowing to edible green corn. It takes about 150 days to about 160 days until it is fully matured.

Day 1 after sowing: germination of embryos;

One week after sowing: small shoots break through the soil;

Around 27 days, the seedlings gradually grow and begin to joint;

At 52 days, corn filaments begin to be drawn out, and male pollen appears at the top;

After fertilization of the male and female in about 90 100 days, the corn filaments slowly dry up or fall off and grow into corn cobs.

120 days for early corn and 95 days for late corn.

If you don't know how to plant corn, you can go to the field to learn how to plant the corn planting and management of pests and diseases.

The growth cycle of corn is about 100-120 days, which has a certain relationship with the local climate and varieties. In the southwest, corn is generally sown in April and harvested in August.

The suitable harvest period for summer maize is from the end of September to the beginning of October. When the bract leaves are dry, the milk line of the grain disappears, the black layer appears and the water content is less than 32%, mechanical harvesting is selected, and the straw is crushed and returned to the field to fertilize the soil.

A large number of practices have proved that late harvest of corn can increase the yield by 750-1500kg hm2, and the 1000-grain weight can increase by more than 15%. When the moisture content of the grain is less than 14%, choose a dry and ventilated site for storage.

The growth cycle of corn varies depending on the variety, geographical latitude, light, planting depth, planting time, etc.

There are three main phases.

First, the seedling stage.

Second, the spike stage.

3. Flower stage.

Central parts of the country, such as central Lu, northern Henan and other places:

Generally sowing in mid to late June, 5 7 days after the emergence of seedlings, early July is the three-leaf stage, mid-July is the seven-leaf stage, late July to early August jointing, mid to late August male pollination, September is the milk maturity period, late September to October is the mature harvest.

The growth cycle of corn is generally about 100-120 days, and there will be some differences in time depending on the variety and geographical environment. Here's a detailed schedule of the corn growth cycle:

1.Sowing period: Seeds are sown in spring (e.g. March-April) or summer (e.g. June).

2.Seedling emergence period: Seedlings can emerge about 5-7 days after sowing.

3.Jointing stage: The plant is high in the state of plucking, the internodes begin to elongate, and visible stems and leaves appear.

4.Small flare stage: 6-8 leaf stage of corn, about 25 cm in height, at this time the field is closed.

5.Big flare stage: The female ears of corn begin to differentiate, the male ears begin to expose the parietal leaves, and visible male ears appear in the leaf axils.

6.Tasseling stage: The tip of the male spike exposes the parietal lobe, which is called tasseling.

7.Silk spinning stage: The filaments of the female spike protrude from the bract, and the spike is red.

8.Grain building stage: After the female panicle is pollinated, the grain begins to form.

9.Milk ripening limb state: Grain volume and weight continue to increase, but the dry matter content is less.

10.Wax ripening stage: The dry matter content of the grains is the highest, reaching the maximum.

11.Maturity stage: The dry matter content of the grains is basically stable and no longer increases.

In the above growth cycle, the different growth stages of corn have different requirements for environmental conditions and agricultural practices, and farmers need to adjust and manage accordingly according to the specific situation.
