How much wheat should be planted and how much fertilizer should be used on an acre of land

20-25 kg of fertilizer, the general sowing rate is 15-30 kg per mu.

The sowing amount of wheat should be determined according to the characteristics of the variety, the early and late sowing date, soil quality, soil fertility level and other factors. Wheat is generally sown early, and the amount of seed is less, and vice versa. The number of seeds with strong tillering ability is small, and the amount of seeds with weak tillering ability is large.

If the soil is heavy and the soil fertility level is poor, the amount of seeds used is large. The general sowing rate of dry stubble wheat field is 15-30 catties per mu.

Fertilizer application rate = (the amount of planned output required for a certain element - the amount of soil supply to a certain element) (the content of a certain element in the fertilizer (%), the utilization rate of the fertilizer in the current season (%)

1. Generally, urea per mu is less than 10 kilograms, and it is advisable to apply shell rain from the end of February to the beginning of March.

2.Foliar spray can be carried out at the booting stage of wheat, with 150 grams of urea and 150 grams of potassium dihydrogen phosphate mixed with 60 kg of water per mu in the afternoon of sunny and windless days.

3. Flat formula fertilization. Nitrogen, phosphorus and potassium must be applied together, and phosphorus and potassium fertilizers should be appropriately increased on the basis of stable nitrogen fertilizer. Reasonable balance of fertilization, so that top dressing, base fertilizer appropriate, according to different soil quality to determine the proportion of base fertilizer, top dressing.

Generally, the ratio of wheat field application in sandy loam soil and light loam soil is 3:7; The application ratio of medium loam and heavy loam soil in wheat fields was 4:6; The application ratio of light sticky and heavy sticky wheat fields is 5:

5。At the same time, attention is paid to the application of various trace elements.

Wheat fertilization. For every 100 kilograms of wheat grains produced, about four kilograms of pure nitrogen, about kilograms of phosphorus, and about kilograms of potassium are needed.

Wheat fertilization should be carried out according to the soil fertility and nutrient absorption law.

Wheat is afraid of the womb, and it is very important to apply plantar fertilizer, so it is necessary to increase the application of organic fertilizer when cultivating the land, and the soil miscellaneous fertilizer needs to be sprinkled with 35 compound fertilizer or 50 kg of wheat special fertilizer.

In the regreening period, according to the growth of wheat, a topdressing of regreening fertilizer is carried out, and 8-10 kg of urea can be applied generally, and the plots without lack of fertilizer can be applied without topdressing.

At the jointing stage and booting stage, 15 to 20 kg of urea per mu were applied.

In the later stage of wheat, potassium dihydrogen phosphate, amino acids, humic acids, and alginic acid foliar fertilizers can be sprayed, which can effectively improve the stress resistance of plants and achieve the purpose of increasing yield.

Hello, the chemical fertilizer used in one acre of wheat generally weighs between twenty and twenty-five kilograms, which is the normal amount of chemical fertilizer used.

Generally speaking, it is a bag of fertilizer per acre, and we usually choose to fertilize 100 kilograms of diamine per acre, 40 kilograms of urea, or a bag of 100 kilograms of wheat professional compound fertilizer.

This question cannot be made subjectively, only a comprehensive analysis of your land fertility and yield targets can make a scientific and reasonable fertilizer budget.

An acre of land needs to sow 33-35 catties of wheat seeds, when planting wheat, it is necessary to apply organic fertilizer after decay in the land to make the soil more fertile, and also need to ensure sufficient moisture, and the water content in the soil can be measured by using a soil moisture detection instrument.

It is also necessary to top dressing the wheat when it is heading to increase the yield.

1. The number of seeds

An acre of land needs to sow 33-35 catties of wheat seeds, when planting wheat, you need to choose excellent varieties of wheat seeds, you can choose seeds with good disease resistance and strong lodging resistance, and you also need wheat seeds and imidacloprid.

Wait for the insecticide to mix and stir, so that each wheat seed is contaminated with the agent, reducing the probability of wheat infection.

2. Apply basal fertilizer

When planting wheat, you need to apply enough base fertilizer in the soil, you can use organic fertilizer after decay, or you can use farmhouse fertilizer made from the manure of chickens, ducks and pigs to provide nutrients for wheat growth, and you also need to plough the soil to make the sowing depth of 3-4 cm to avoid reducing the emergence rate of wheat seeds.

3. Sufficient moisture

Wheat needs sufficient water in the growth process, when planting wheat, you need to ensure that the soil is moist, you can use the soil moisture detection instrument to check the moisture in the soil, if the water content in the soil is higher than 60%, you do not need to water the wheat to avoid its death, and you also need to drain the water in the soil for the wheat in heavy rainy weather.

4. Carry out top dressing

When cultivating wheat, it is necessary to top dressing the plants during their heading period, and nitrogen, phosphorus and potassium can be applied to the soil.

Compound fertilizer, so that the yield of wheat increases, also needs to grow 6-7 true leaves in wheat.

, spray potassium dihydrogen phosphate on its leaves.

Increase the weight of wheat grains and maintain the normal growth of plants.

About 30 kg of compound fertilizer should be applied to one mu before wheat sowing.

Before wheat sowing, 80 kg of compound fertilizer per mu is applied as base fertilizer, which also depends on the composition of compound fertilizer. Wheat sowing and fertilization, generally speaking, compound fertilizer per mu is 20-30 kg, depending on the land. In the past, wheat sowing was generally planted with fertilizer, and according to different soil fertility, wheat sowing was generally applied about 30 kg of compound fertilizer per mu.

The soil fertility is different, the fertilization level is different, generally about 30 kg. Generally, 25-30 kg of special compound fertilizer per mu, and about 30 40 kg of 45% special compound fertilizer per mu for wheat sowing. Wheat sowing is generally applied with 51% content of 50 kg of special compound fertilizer per mu.

Wheat is divided into spring wheat and winter wheat, spring wheat is better sown in March and April, and winter wheat is better sown in September and October, because the conditions in each region are different, so it is necessary to choose the right time for sowing.

Here are three things to pay attention to when sowing wheat:

1.Wheat can be dried twice before sowing, generally 30-200 days before sowing, and then 3-5 days before sowing, which can accelerate the activity of enzymes in seeds and is conducive to seed germination.

2.In the preparation of the land, it is necessary to carry out deep ploughing, the depth is generally 25-30cm, which is conducive to root growth, improves the drought resistance and cold resistance of wheat, and can also reduce the germs in the soil.

3.Pesticide seed dressing before sowing can control a variety of underground pests and a variety of soil-borne diseases of wheat.

Planting wheat, how many catties can be sown in an acre of land to achieve high yield? 30 pounds is good? Or is 50 pounds good?

One acre of land must be sown with less than 10 kg of wheat seeds to achieve high yield. Some professional studies have shown that the highest yield per mu is controlled within 10 kg, because by controlling the sowing amount of wheat, the occurrence of pests and diseases and the threat of large-scale lodging in the late growth stage can be reduced. One acre of land must be sown with less than 10 kg of wheat seeds in order to achieve high yield.

Studies have shown that the sowing amount of wheat per mu is best controlled within 10 kg, so that by controlling the sowing amount of wheat, the occurrence of diseases and pests or the risk of large-scale lodging in the late growth stage of wheat can be effectively reduced.

If it is sandy land, it is relatively poor soil water retention capacity, so an acre of land planted with 25 catties to 30 catties of seeds can be, if it is a medium fertility plot, that is to say, the fertility of this land is average, then the sowing amount of wheat is controlled in an acre of land 18 catties to 20 catties is about the same.

<>1. The yield of wheat planting in different regions will be different, such as the Huaibei region in central China, where one acre of land can produce 1000-1200 kg of wheat. In Anhui Province and Henan Province in China, one acre of land can produce about 1,000 catties of wheat. In China's areas along the Yangtze River, one acre of land can produce 500-600 catties of wheat.

2. One acre of wheat needs to use 20kg-25kg of chemical fertilizer. It should be noted that when fertilizing wheat, it is necessary not only to apply sufficient basal fertilizer, but also to apply appropriate topdressing at the appropriate time.

1. How many catties of wheat are in one acre of land.

1. The yield of wheat per mu in different regions is different, and the yield of wheat will be higher in areas suitable for planting, such as the Huaibei region of the central province of China, the yield of one mu of land is at least 1000 catties, and the yield can exceed 1200 catties when the yield is high. In most areas of Anhui Province and Henan Province in China, the yield of wheat per mu can exceed 1,000 catties. However, the yield of wheat in some areas is not high, such as the areas along the river, the yield per mu is generally 500-600 catties.

The total annual wheat output in China is 10,000 tons, the total sown area is mu, and the average yield per mu is catty. In 2019, China's total wheat output was 10,000 tons, the total sown area was mu, and the average yield per mu was catty.

2. How much chemical fertilizer is needed for one acre of wheat.

1. Generally, 20kg-25kg of chemical fertilizer is needed for one acre of wheat. Wheat growth requires sufficient nitrogen and potassium, and proper topdressing should be followed by plantar fertilizer. Generally, every 50kg of wheat grains should absorb 1kg-2kg of pure nitrogen, phosphorus and potassium.

2. If the wheat in the jointing stage is thin, the leaf color is yellow early, and the tillering is less, the topdressing time should be 5-7 days in advance. 15kg-20kg of sulfur-containing potassium-controlled slow-release urea per mu is generally effective for 3 consecutive days. The topdressing rate of dark green leaf color, large population and continuous tillering can be appropriately increased.

3, wheat jointing period to the development period, more suitable for wheat topdressing, the amount of topdressing according to the specific situation of wheat seedlings to determine, the normal growth of wheat topdressing time is generally in early March, in the obvious internode when topdressing, will not make the root internode too long. Proper topdressing can meet the demand for fertilizer in the growth and development stage of wheat, promote the healthy growth of wheat, increase the ear length and 1000-grain weight, and increase the number of grains per spike.

4. The specific fertilization plan of wheat should be formulated according to the comprehensive fertility of the soil, which is generally based on organic fertilizer, combined with inorganic fertilizer application, fertilization can make the organic matter content in the soil more balanced, and improve the content of lysine and protein in wheat grains.
