How to accurately calculate the amount of sowing per acre

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. 1. The planting of wheat must maximize the development of individuals and groups to achieve the purpose of multiple ears and large grains, which is the basis for determining the reasonable sowing amount. Some farmers often sow too much, which is easy to cause wheat lodging and aggravation of pests and diseases, and eventually lead to insufficient grains and low yields.

2. In order to meet the production requirements of high yield, it is also necessary to determine the actual sowing amount according to the characteristics of wheat varieties, soil fertility, the quality of land preparation, and the sowing time of morning and evening. Semi-winter varieties generally have a sowing rate of 6 to 8 kg per mu and an ear formation of 400,000 to 450,000, while spring varieties generally have a sowing rate of 7 to 9 kg per mu and an ear formation of 350,000 to 400,000.

If wheat wants to obtain high yield, it is necessary to sow all seedlings at one time, achieve seedling Qi, seedling uniformity and seedling strength, and create a reasonable bumper yield group for next year's wheat high yield and stable yield is the key. This requirement can only be met by accurately and flexibly grasping the amount of seeding.

First of all, the target yield should be determined according to the soil fertility and water and fertilizer conditions, the number of ears per mu should be determined by the target yield, and then the appropriate basic seedlings should be determined by the number of ears per mu, and then the appropriate sowing amount should be calculated according to the basic number of seedlings, the 1000-grain weight and germination rate of the variety, and the seedling emergence rate in the field.

The calculation method of one acre of land is as follows:1. The traditional formula for calculating the number of acres of land:1 acre 60 sq m 6000 sq ft.

One square meter is equal to one acre.

Simple calculation method, formula :Number of acres of length (m) x width (m).

Example 1: How many acres of land is 200 meters long and 150 meters wide?

200 m x 150 m.

45 (acres).Simple Calculation, Equation:Length (m) x width (m) 667

One square meter is equal to one acre.

Example 2: How many acres is the area of a piece of land 60 meters long and 40 meters wide?

60m x 40m 667

acres) acres).2. Calculation method of folk formulasThe formula for converting square meters to acres is:

Add half to the left and move three "".

Example 3: How many acres is 128 square meters?

Calculation method: use half of 128+128 first.

mu) and then move the decimal point to the left by three places, that is, the number of acres obtained is: mu.

acres

"Mu" is a unit of land area in China, so it is calculated according to the length and area units of China. 1 zhang = 10 feet, 1 square foot = 100 square feet, 1 mu = 60 square feet.

How is the formula for calculating mu.

Three-dimensional loneliness. Concern.

In our daily life, especially farmers, we often have to calculate the area of land, and here is a simple calculation method.

Tool Raw Material Calculator.

Method: Read step by step.

The traditional formula for calculating the number of acres of land is: 1 mu = 60 square feet = 6000 square feet = square meters.

We usually find the number of acres, and generally use a simpler calculation method. The formula is: length (m) width (m) number of acres.

For example, the land area of 200 meters long and 150 meters wide is:

200 (m) 150 (m) sq m mu).

Length (m) Width (m) 667 = number of acres.

For example, if a piece of land is 60 meters long and 40 meters wide, the formula is 60x40 667 and the number calculated is the number of acres.

There is also a more practical formula for folks to calculate: square meters are exchanged for acres, and the calculation formula is "add half and move three left".

For example: 1 square meter mu, such as 128 square meters is equal to how many acres?

The calculation method is to add 128 to half of 128: 128 64 192, and then shift the decimal point to the left by 3 places, that is, the number of acres is.

Mu is not a standard unit, generally one mu is equal to 666 square meters.

Hello friends, I will answer the questions. How to calculate the mu of land 1, the conversion formula of land area 1 hectare = 15 mu = 10,000 square meters, 1 mu = 10 cents mu = 60 square meters = square meters, 1 acre = 100 square meters, 1 square meter = mu. 2. Conversion between square meters and acres (1) Measure the length and width of the land (m), and then use the length and width to convert square meters into acres.

2) The calculation method of converting square meters to acres (the formula is to add half and move three left): For example, there is a piece of land of 60 square meters. Add by half, that is, 60 + 30 = 90.

Shift three to the left, i.e. 90 1000=. Therefore, 60 square meters is an acre. (3) The calculation method of converting mu to square meters (the formula is divided by three and doubled to the right by three):

Let's say there are 48 acres of land. Divide by three, i.e. 48 3=16. Double, that is, 32.

Summary. Good afternoon, kiss! We're happy to answer for you!

The calculation method of one mu of land is as follows: 1. The traditional formula for calculating the number of acres of land: 1 mu 60 square zhang 6000 square feet square meter One square meter is equal to one mu.

Example 1: How many acres is 200 meters long and 150 meters wide? 200 m x 150 m chain is not 45 (acres).

The calculation formula of the folk formula for calculating the lack of friends is converted into acres of jujube square meters, and the calculation formula is: "add half to the left and move three" example 3: 128 square meters, which is equal to how many acres? Calculation method: first use 128 + 128 half of the Fuyan acacia 128 128 2 192 mu).

Then move the decimal point to the left and the number of acres obtained: mu. Mu "mu" is the unit of land area of the Chinese municipal system, therefore, its calculation method is calculated according to the length and area unit of China.

1 zhang = 10 feet, 1 square foot = 100 square feet, 1 mu = 60 square feet.

One acre of land is equal to 666 and two-thirds of a square meter. You first measure the area of your land, and then divide it by this number to get the number equal to how many acres.

Answer: Mu is the unit of land area of the Chinese municipal system, one mu is equal to 60 square abbots, about square meters, 1 square meter is equal to mu, and 15 mu is equal to one hectare. The conversion of mu to square meter can be estimated by the relationship between "square meter", "zhang" and "ruler". Or use the calculation formula:

Add half to the left and move three "".

The number of square meters can be calculated according to the area formula, and then converted into the number of acres;

1 acre = square meter.

Mu is a unit of land area in China, one mu is equal to sixty square abbots, about square meters. Fifteen acres is equal to one hectare. This is the ancient Chinese method of counting. Nowadays, most counts are rounded in units of ten, and in ancient times, they were mostly rounded in units of "60".

In ancient times, mu was a vague concept, and "mu" as a unit of land volume could be counted by the number of scales, so the "mu" mentioned here was actually used as a quantitative word to indicate length.

Tell us how to quickly calculate the number of acres of land.

If it is a regular graph, the number of square meters is calculated according to the area formula, and then converted into the number of acres;

1 acre = square meter.

For example, a rectangle, measured length = 30 meters, width = 23 meters, area = length and width = 30 23 = 690 (square meters) = 690 acres).

How many square meters is an acre of land?

1 hectare = 100 acres (ares).

1 hectare = 15 acres.

1 hectare = 053 8 acres 1 acre = square meter.

Algorithm: length * width 667 = mu.

It is not limited to the length and width, as long as the area is about 667 square meters, it is one acre.
