Generally speaking, what is the yield per mu of excellent varieties of corn?

There are not many varieties that can shout "tons of grain per mu" in the Northeast. Especially in the case of serious pests and diseases in recent years, some stable yield, high yield varieties can not be effectively reflected corn is a cash crop, but also an excellent food crop, in our north, generally planted, corn wants high yield, naturally inseparable from planting and management experience. There are many factors that determine corn yield, and differences in geographical environment, varieties, cultivation management techniques, etc. may lead to differences in corn yields, generally speaking.

Generally, the yield of summer maize is higher than that of spring maize and autumn maize, mainly due to the difference in growth period, light and accumulated temperature! The third is the problem of corn varieties, which is also the biggest influencing factor! At present, the yield of genetically modified corn per mu introduced in China can reach up to 3,000 catties in Heze, we Heze is a corn planting base, the yield and variety of corn, the soil quality is very related, in our local area, the highest yield reaches 1,600 catties, the yield of good soil quality is about 1,350 catties, and the normal yield is about 1,000 catties The yield of corn is determined by many factors, and it is also a matter of concern to farmers.

We are from Yining County, Yili, Xinjiang, and we all grow corn here in spring.

Spring corn has sufficient water and fertilizer, and insect disease control is 1,500 to 1,800 catties. Summer corn is about 800 to 1,000 catties. This year's drought has watered about 800 catties, not watered the harvest loss of 200 yuan of seeds, cultivated land seeds spend fertilizer money, the high-yield field selection of dense and high-yield varieties of high-yield, the implementation of dense planting and high-yield mechanized cultivation and water and fertilizer integration technology, excavation of improved seeds, good methods and light, temperature, water and fertilizer resources to increase the yield potential, after 12 years of systematic research, many times created a national corn high yield record.

Our Puyang belongs to the Huang-Huai-Hai alluvial plain, with flat terrain, fertile soil, sufficient sunshine, convenient irrigation and drainage, and is an advantageous corn producing area. The yield of corn per mu is generally 800-1200 catties, and the high yield reaches about 1500 catties. If the grass is not removed regularly and not watered regularly, then even in high-quality seeds, there will be no good harvest, and generally this kind of harvest can have 7 8 hundred catties.

Generally speaking, the yield per mu of a good variety of corn is about 3,000 catties, which is very much, which is a very good value.

The yield per mu is about 1200 1600 catties, and if it is planted scientifically, the yield may be higher.

Generally speaking, the yield per mu of excellent varieties of corn is about 800 1200 catties.

Generally speaking, the yield per mu of excellent varieties of corn is generally 800 1200 catties, and the yield is still quite good.

<> mu yield of 3,000 pounds of corn has Lianchuang 825 and other varieties. Lianchuang 825 has very good adaptability, and has passed the examination and approval in the three major corn producing areas in China, which is not only suitable for summer sowing, but also suitable for spring sowing, and is a corn variety with wide adaptability. The key points of cultivation technology are planting in the northwest spring maize area, and the suitable sowing date is from late April to early May, with a planting density of 5000-5500 plants per mu.

1. Corn varieties with a yield of 3,000 catties per mu

1. There are varieties of corn with a yield of 3,000 catties per mu, such as Lianchuang 825. The adaptability of Lianchuang 825 is very good, and it has passed the examination and approval in the three major corn producing areas in China, which is not only suitable for summer sowing, but also suitable for spring sowing, and has become a corn variety with a very wide adaptability. The average plant height is 276 cm in the summer maize area, the ear height is 100 cm, the number of adult leaves is 19-20, the average yield per mu in the summer maize area is 276 cm, the average yield per mu in the spring maize area is 1 kg, and the yield increase potential of the high fertilizer and water plots is huge, and the highest yield per mu can reach more than 1500 kg.

2. The cultivation technology of Lianchuang 825 is planted in the northwest spring maize area, and the best sowing date is from late April to early May, with a planting density of 5000-5500 plants per mu; In the summer maize planting area, the best sowing date is from late April to early May, and the planting density per mu is about 4500-5000 plants.

Attention should be paid to the prevention and control of corn borer during the big flare period.

In the middle and late stages of growth, attention should be paid to the prevention and control of corn size spot disease and aphids.

and other pests and diseases. It is suitable for planting in Heilongjiang, Jilin, Inner Mongolia, Liaoning, Beijing, Tianjin and other provinces and municipalities in the North East China spring corn area, and also suitable for planting in Ningxia, Heilongjiang, Gansu and other spring corn areas.

2. How to increase corn yield

1. Soil fertilizer.

The land where corn is planted is generally to be reclaimed for the second time, and all the roots of the crops planted in the previous year can be turned out to prevent the normal growth and germination of corn seeds when planting corn, if the nutrients in the soil are insufficient, it is necessary to add appropriate farm fertilizer to the soil, it is recommended to use some poultry manure, animal manure has the advantage of good nutrients.

2. Soil disinfection.

Before planting corn, it is necessary to pay attention to the disinfection of the soil, and after the land has been cleared, quicklime can be used.

Or potassium permanganate.

Carry out a comprehensive disinfection of the soil, and when disinfecting, you must pay attention to avoid the rainy season, because the rain will wash away all the potassium permanganate and quicklime, and the soil disinfection at this time will have little effect.

3. Seed selection.

According to the conditions of light and heat resources in various places, the scientific variety layout and reasonable maturity collocation. Select excellent varieties with high yield and stable yield, disease and insect resistance, stress resistance, resource efficiency, and suitable for mechanized operations that have passed the national or provincial examination (recognition), and the varieties should be suitable for maturity, and the planting should be eliminated from crossing the area to ensure safe maturity. In the maize structure adjustment area, according to local conditions, choose to choose the high-quality special or grain-feed silage corn that has passed the national or provincial examination (certification) and is suitable for local planting.

varieties, pay attention to the purchase of high-quality coated seeds, improve the emergence rate and group uniformity, and prevent seedling pests and diseases and underground pests.

There is no corn variety with a yield of 4,000 catties per mu.

At present, there is no corn variety with a yield of 4000 catties per mu, and the yield per mu of most corn is about 1000-1400 catties, and the yield per mu will also be affected by factors such as planting area, environment, variety, technology, etc., if the planting technology is good and the corn varieties are of high quality, it is usually helpful to improve the yield of corn.

The corn varieties with relatively high yield mainly include Denghai 710, Xianyu 1225, Heyu 187, Denghai 605, Zhongkeyu 505, etc., among which Xianyu 1225 belongs to the new corn varieties with high yield and large ears, the plant type is semi-compact, the plant height is about 312-317cm, the average yield per mu is generally about 1600 catties, and the yield per mu can reach about 2670 catties.

Methods of growing corn:

1. Land. It is suitable for planting corn in loose soil, deep soil, and rich organic matter.

2. Seed selection. According to the actual situation of various places, high-quality corn varieties with strong lodging resistance and good disease resistance should be selected.

3. Sow seeds. You can make a hole in the soil, and then sow the seeds, the depth of sowing is generally 5cm, and the sowing is completed according to the soil moisture in time. Carry out seedling determination when the corn is 5 leaves, and pull out the diseased seedlings, weak seedlings, and different plants in time, retain the robust seedlings, and need to replenish the seedlings in time after the lack of seedlings.

4. Daily management.

Temperature: The appropriate temperature for seed germination is 28-35, the temperature is generally required to be 15-27 at the jointing stage, and the temperature needs to be kept at 25-26 after entering the flowering stage, and the temperature at the filling stage is 20-24.

Light: Corn is a short-day plant that can generally flower and bear fruit in short-day conditions (8-10 hours).

Moisture: Corn needs a lot of water, so it needs to be watered reasonably according to the growth of the plant.

Fertilization: nitrogen fertilizer needs to be applied in time during jointing, booting, tasseling and flowering and grain filling, and nitrogen fertilizer can generally be applied to 10-20kg mu (whole growth period).

Cultivating and weeding: In the growth period of corn, it is generally necessary to cultivate the soil 2-3 times, and at the same time, it is also necessary to remove the weeds in the field in time.

Prevention and control of pests and diseases: common pests and diseases of corn mainly include leaf spot, powdery mildew, corn borer, mole cricket, ground tiger and other types, which need to be selected according to the type of pests and diseases to prevent and control, such as leaf spot can generally be sprayed with 800 times of 50% compound thiophanate-based wettable powder.

Summary. Dear, I'm honored to have your question The information that the teacher found for you here is: corn varieties with a yield of 4,000 catties per mu:

Recommendations <>

Now that the epidemic is repeated, you must pay attention to safety when you go out, <> go out, wear a mask, wash your hands frequently! Have a great day, <>

At present, there are no corn varieties with a yield of 4,000 catties per mu, and the corn varieties with high yield include Baoyu Longgao L2, Jinchong No. 1, Dongdan 1331, Shuoyu 668, Fengle 742 and so on.

1. Baoyu dragon height l2

This variety is the corn variety cultivated by the Heilongjiang Academy of Agricultural Sciences, at present, it has been planted in a large area in Heilongjiang, and other regions are also conducting trial planting, this variety has broken the record of more than 3,000 catties per mu, and the average yield per mu is about 1,000 kilograms.

2. Jinchong No. 1.

Jinchong No. 1 corn is a variety cultivated in Inner Mongolia, this variety has good adaptability, disease resistance, cold resistance, lodging resistance, the average yield per mu is more than 1600 catties, the highest yield per mu exceeds more than 2000 catties, in the three northeastern provinces and Inner Mongolia, Xinjiang and other places are planted, other areas can be tried first, and then promoted.

3. Dongdan 1331

Dongdan 1331 is a corn variety approved by the state, widely planted in Northeast China and North China, suitable for planting in most corn planting areas, with an average yield of about 1600 kg per mu, up to 2000 kg, and the growth period is 125 days to 135 days depending on the region.

4. Master's education 668

In addition to the northeast region, this variety is suitable for planting in most of the main corn producing areas, and in the comparative experiment, the yield per mu of 668 corn varieties has reached more than 1400 catties, which is a suitable corn planting variety in the north and south.

5. Fengle 742

Fengle 742 is a new corn variety bred by Shanxi Academy of Agricultural Sciences, with an average yield of more than 2,000 catties per mu in the main corn producing areas in 19 years. High yield reached 2,500 catties, was selected as the first branch of corn high yield, this year has been in the northeast three spring section of the province, Hebei, Shandong and other regions have a large area of spring sowing, but also suitable for the Yellow River Basin corn production area summer sowing.

The yield of corn is not fixed, and will vary depending on the variety and planting area, for example, the yield of spring corn per mu in the three eastern provinces is about 1000 to 1400 catties.

1: How many catties of corn is generally produced per mu?

Yields vary greatly from region to region, and from variety to species.

The yield per mu of spring maize in the three eastern provinces is generally about 500-700 kg (under the standard water content of 14 waters), the summer maize area of Huanghuaihai is generally about 600 kg, and the yield in Xinjiang is the highest up to 700-900 kg.

Two: Corn ** a few reasons:

1."One look" runs.

After the cancellation of the acquisition of the city, ** fell sharply, 1400 yuan is the bottom, appeared in the 16 years of the new grain listing period, every year when the new grain is listed will hit a low point, this is a more obvious law. We believe that in 2018, the domestic corn ** will be at the bottom and at the top, fluctuating in the range of 1500-1900 yuan. At present, we expect that there may be ** lows in April and October, respectively, because the auction will start in May, and the market expects that the ** may be knocked down, and new grain will be listed in October.

2."Second look" inventory.

What is the national inventory? When to put it? This is critical.

However, at the moment, the inventory may not be as large as previously stated, and the quality still needs to be considered. At the same time, the 2017 corn area is reduced and the total amount is not much, which may be an important weight. At present, there are 100 million tons of grain reserves, 53 million tons in 14 years, and they are already facing the problem of aging, 100 million tons in 15 years.

3."Three looks" consumption.

Mainly two large pieces of consumption.

1) Deep processing is the highlight, here is the capacity distribution of deep processing.

2) Feed breeding, can reproduce the sow after the correction through the PSY, or in a relatively low position, which will affect 8 months after the pig **, so the pig ** overall is still difficult to have a big change, this is the short and medium-term, in the long run, the proportion of large-scale breeding is higher, the disturbance factor of disorderly production capacity is getting smaller and smaller, and the pig will be more balanced. Feed consumption for maize will also flatten.

4."Four looks" policy.

There are three main aspects of policy.

1) According to the national plan, the corn area will be reduced by 70 million mu by 2020, but we see that 73 million mu has been achieved in 17 years. In addition, compared with the planting income of soybean, corn and rice, corn is higher than soybean, soybean 4100, corn 3500, farmers' planting enthusiasm will be very high. So we think there could be a slight increase in area in '18.

2) Reserve grain to destock. Do not doubt the determination of the state to destock. The ** of the collection and storage is more than 2000, which shows the determination of the country. However, in the downturn, the weekly auction volume will still be lowered, and it will not suppress the market, which is more flexible.

3) Subsidy policy, after the auction, the market will expect the introduction of subsidy policy, which is generally a positive policy, after all, the state will think about farmers.
