How to calculate row spacing and plant spacing for corn sowing?

First of all, you have to calculate the planting area yourself, and then divide it by the length and width, so that you can calculate the travel distance and plant spacing.

If you don't know how to calculate, then you rent a cultivator and it will calculate the distance directly when it plows.

Corn plant spacing calculation formula:

1. Calculation method of single-grain sowing high-quality seeds.

Precision sowing plant spacing (m) = 667 ( ) average row spacing (generally the number of seedlings per mu and the seed germination rate (92%).

1 mu = 667 square meters = 6,000 square feet. If you use the wide and narrow row method, you must first calculate the average line spacing. Seeding quality and herbicides.

When the loss of seedlings caused by the emergence is large, it is necessary to appropriately reduce the plant spacing and not thin the seedlings.

2. Semi-precision sowing empty auspicious key seed calculation method.

Semi-precision sowing plant spacing (m) = 667 ( ) average row spacing (generally the number of seedlings per mu. When sown with half a plant spacing or two grains in one hole, the general seed germination rate is 85% to 92%. When the seedlings are fixed, the seedlings are set according to the plant spacing, and when the seedlings are missing, a hole is left nearby.

Corn planting essentials

1. Seed selection. When planting corn, it is necessary to select high-quality and improved seeds, which can have good resistance and emergence rate when planting. Generally, medium and late maturing varieties with high yield potential, dense tolerance and compactness, and large spike type are preferred.

2. Land preparation. Before corn planting, in order to make corn have a better growth environment, it is necessary to carry out meticulous land preparation, generally to achieve two plows and two harrows, and the depth of the tillage layer is more than 30 centimeters to achieve"The ground is flat, the soil is fine, the moisture is sufficient, and the fat is high"quality requirements for land preparation.

3. Apply basal fertilizer. The application of base fertilizer should be carried out together with land preparation, generally 1000 kg of rotted farmhouse fertilizer, 50 kg of soybean cake bucket and superphosphate per mu.

50 kg.

Corn planting row spacing is generally 55-60 cm, and plant spacing is 24-30 cm. In production, you can use 70-80 cm wide row spacing planting, can also use 40-50 cm wide row spacing for planting, or use 60-70 cm equal row spacing planting, planting must follow the principle of fertile land should be dense, thin land should be thin.

1. Plant spacing is 22 cm, row spacing is 50 cm, mu (the number of plants is 6061.

Plant spacing 22 cm, row spacing 55 cm, mu (number of plants 5510.

The plant spacing is 22 cm, the row spacing is 60 cm, and the number of plants per mu is 5051.

2. Plant spacing is 25 cm, row spacing is 50 cm, mu (the number of plants is 5334.

Plant spacing 25 cm, row spacing 55 cm, mu (4849 plants.

Plant spacing 25 cm, row spacing 60 cm, mu (number of plants 4445.

3. The plant spacing is 30 cm, the row spacing is 50 cm, and the number of plants per mu is 4445.

The plant spacing is 30 cm, the row spacing is 55 cm, and the number of plants per mu is 4041.

Plant spacing 30 cm, row spacing 60 cm, mu (number of plants 3704.

4. The plant spacing is 33 cm, the row spacing is 50 cm, and the number of plants is 4041.

Plant spacing 33 cm, row spacing 55 cm, mu (number of plants 3673.

Plant spacing 33 cm, row spacing 60 cm, mu (3367 plants.

Calculation method of corn plant spacing.

1. Sow high-quality seeds in a single seed.

Precision sowing plant spacing (m) = 667 (square meters) Average row spacing (m, generally m) Number of seedlings per mu Seed germination rate (generally greater than 92%); 1 meter = 3 feet = 30 inches.

It is the same according to the size, 1 mu = 667 square meters = 6000 square feet.

The average row spacing can be calculated first, and the seedling spacing should be appropriately reduced when the seedling loss caused by sowing quality and herbicides is large, and the seedlings should not be thinned.

2. Semi-precision sowing seeds.

Semi-precision sowing plant spacing (m) = 667 (square meters) Average row spacing (m, generally m) Number of seedlings per mu; 1 meter = 3 feet = 30 inches.

When sowing with half plant spacing or two seeds in one hole, the germination rate of seeds is generally greater than 85% but less than 92%. When the seedlings are set, the seedlings are set according to the plant spacing, and when the seedlings are missing, leave a hole and two plants nearby.

3. How to count the number of corn plants (trees) in a field?

Number of plants (trees) = [(ground length, plant spacing) + 1] [ground width, row spacing) + 1].

For example, in a plot of 30 meters long and 20 meters wide, the corn should be planted according to the row spacing of 60 cm and the plant spacing of 30 cm.

30 = 3434 trees.

4. Corn density table.

There are two ways to grow itOne is to combine the past two ridges (60 cm 65 cm apart) into a large ridge, and plant two rows of corn on the ridges, with a spacing of 40 cm between small rows and 80 cm or 90 cm between large rows; In the second way, the past ridges are combined into two large ridges, and two rows of corn are planted on each large ridge, that is, from the past three rows to four rows, with a spacing of 30 cm between small rows and 60 cm or 67 5 cm between large rows. The plant spacing is about 25-27 cm. The planting density should be determined according to the level of local cultivation and the characteristics of the variety.

Method. Corn planting should first choose excellent seeds, before planting can be soaked and germinated, so that the germination rate can be improved, and when you see white roots come out, you can sow seeds, corn sowing, to choose loose and fertile, good drainage of sunny soil slope for planting, before planting the land to carry out deep ploughing.

The time of corn planting is in early April in the spring of each year, the depth of sowing is 4 5 cm deep into the soil, usually about 10 days will sprout, after rubbing the teeth can be squatting seedlings, mainly to cultivate the drought tolerance of the plant, as well as let his root system get a good growth, corn likes fertilizer.

A large amount of fertilizer is needed in the planting process, fertilizer should be applied every 10 15 days, attention should be paid to the coordinated supply of phosphorus, nitrogen and potassium fertilizer, and the field should be diligent in weeding to prevent them from competing with crops for fertilizer. Although corn is drought tolerant, during the flowering and fruiting period of corn, there can be no lack of water, otherwise it will cause the phenomenon of empty fruit, after 4 to 5 months of growth, usually the first batch of corn can be harvested in August --- September.

The row spacing for corn planting is generally 50-60 cm, the plant spacing for spring sowing is 33-40 cm, and the spacing for summer sowing corn is 25-33 cm.

The density of spring sowing corn can reach 3,300-4,000 mu, and the density of rot-sowing corn in summer can reach 4,000-4,500 mu.

In order to ensure high yield, it is generally necessary to determine the specific planting plant row spacing according to the characteristics of corn varieties, if the stem and leaf angle is small, the row spacing of corn with leaves growing upwards can be relatively reduced.

1. What is the plant spacing and row spacing of corn planting?

1. Plant spacing. 1) The plant spacing of spring-sown corn is generally 33-40 cm, and the planting density per mu is 3300-4000 plants.

2) The plant spacing of summer-sown corn is generally 25-33 cm, and the planting density per mu is 4000-4500 plants.

2. Line spacing. 1) The row spacing of corn planting is generally between 50-60 cm.

2) For the dense-tolerant varieties with small stem and leaf angles, leaf uplash, and deep root development, the row spacing can be appropriately reduced.

3) For large spike varieties with tall stems and flat leaves, the row spacing can be appropriately increased.

Second, the planting method of corn

1. Seed treatment refers to leakage.

1) Choose varieties with high disease resistance, high yield, high stability, and suitable for local planting.

2) Place in the sun for 2-3 days to dry the seeds sufficiently.

3) After the sun, the seeds are soaked in clean water for 12-24 hours, and the seeds are mixed with pesticides after being removed.

2. Soil rolling and leasing treatment.

1) Ploughing the soil for about 15 cm on a cloudy day can make the corn better rooted in the soil.

2) At the same time, organic fertilizer, as well as an appropriate amount of ammonium sulfate and urea are applied as base fertilizer.

3. Sowing depth.

1) Generally, the sowing depth is 5-6 cm.

2) In the clay with good moisture content, it needs to be sown shallowly, and the depth should be 4-5 cm.

3) In dry loose soil, it is necessary to sow deeply, and the depth is 6-8 cm.
